ABSTRACT
The study was conducted at the Benguet State University experimental project
from October to December 2011to compare the level of garlicand with antibiotic premix
on water on the growth performance of sunshine chicken, feed consumption, feed
efficiency, morbidity and mortality, and lastly on the return of investment.
A total of 160 Sunshine Chicken day old chicks were randomly distributed after
having a 5 day trial feeding into four treatments following the Complete Randomized
Design (CRD). The four treatments were replicated four times with ten birds per
replicate.
The result and observation showed after 56 days of the experiment that there were
no significant in terms of the initial weight and total feed intake. While on the feed
conversion ratio it was shown that it is significant same as through on the final weight,
total feed intake, average daily gain, and total feed cost required to produce a kilogram in
weight which has a result of highly significant.
Apparently, the treated sunshine chicken with 30 grams of garlic granules has a
better effect when it comes to its final weight, total gain in weight, average daily gain and
on the return on investment which has a higher percentage than those of the other
treatments of 31.75 %.

INTRODUCTION
Animal raising is an important and diverse component of Philippines Agriculture
and one of it is poultry production which is a practice of raising domesticated birds, for
the purpose of meat and egg as a part of our diet.
Feeding has a great effect in the growth of poultry industry and almost research
now a day is focused on finding new supplement that improves animal performance
that’s why it is important to the raisers to know what the best feed is for their bird is. And
we know the fact that chickens are omnivores, eating most anything they find. This eating
habit of chicken makes them easy to feed a variety of supplemental feed. Though
commercial feed provides a good base diet for chicken, it is still efficient if we add an
herbal supplement on their diet which could boost its growth performance that will
increase our profit.
This study allows us to improve more on chicken traits such as performance, and
immune response. It was also conducted to find out the effect of garlic granules as a feed
supplement to sunshine chickens. The result of this study can serve as a guide in using
garlic granules as a feed supplement in chickens.Lastly, the research can be a good start
to enhance the performance of chickens that can result to high income and profit.
The Studyspecifically aimed todetermine the effect of garlic in terms of: growth
performance, feed consumption, feed efficiency, morbidity and mortality of chickens, and
return on investment. And to determine the best level of granulated garlic to be utilized as
feed supplement for sunshine chicken.
This study was conducted at the Benguet State University (BSU) Poultry
Experimental House Balili, La Trinidad, Benguet.

REVIEW OF LITERATURE
Chicken broiler and egg production are the most progressive animal enterprises in
the Philippines today. The poultry industry in fact began as a backyard enterprise but has
shifted to the formation of very large integrated contract farming operations. The growth
of poultry industry in the Philippines has indeed been impressive but its problems
including inefficient management and the prevalence of many destructive poultry
diseases and parasites cannot be ignored (EPA, 2005).
The practice of complementary and alternative medicine is now on the increase in
developing countries in response to World Health Organization directives culminating in
several pre-clinical and clinical studies that have provided the scientific basis for the
efficacy of many plants used in folk medicine to treat infections (Vijaya and Ananthan,
1997; Dilhuydy and Patients, 2003; Iwalokun et al., 2004). Previous studies have
demonstrated positive effects of herbal supplements on production performance and
carcass quality to chickens (Schleicher et al., 1998; Tekeli et al., 2006, 2008).
In pursuit of improved broilers health and in order to fulfill consumer expectation
in relation to food quality, poultry producers commonly apply natural feeding
supplements, mainly herbs (Gardzielewska et al., 2003).
Garlic is one of the most beneficial natural food supplements. This is because of
garlic's numerous significant health benefits. First of all, garlic helps to detoxify the body
while enhancing the immune system. This makes garlic beneficial for fighting colds and
infections. Garlic also is well known as a natural way to lower blood pressure while
improving circulation. However, the benefits of garlic don't stop here. Garlic lowers
blood lipid levels, helps to stabilize blood sugar levels, and may even help prevent ulcers.

Garlic is helpful for virtually any disease or infection, making it one of the most popular
herbal food supplements (Anonymous, 2007).
Garlic, a member of the Allium family (Liliaceae), has been used traditionally for
ages to treat a wide array of diseases, namely, respiratory infections, ulcers, diarrhea and
skin infections (Fenwick and Hanley, 1985). Reuter et al. (1996) reported garlic as a
plant with antibiotic, anticancer, antioxidant, immunomodulatory, anti-inflammatory,
hypoglycemic and cardiovascular- protecting effects.
Moreover, garlic is very rich in aromatic oils, which enhance digestion and
positively influenced respiratory system being inhaled into air sacs and lungs of birds.
Also it was found that garlic has strong antioxidative effects (Gardzielewska et al., 2003).
Garlic extract and/or garlic components were able to prevent chemically induced
tumors or acute toxic effects of chemicals. The chemo-preventive potential of garlic has
been attributed to the presence of several bioactive organosulfur compounds. These
compounds might act as antioxidants (Fanelli et al., 1998; Siegers et al., 1999). The
antioxidative stress properties of garlic might result from the contributions of its sulfur
component in different steps and not necessarily from the contribution of only one of
them (Fanelli et al., 1998). Garlic also has been shown to have strong antimicrobial
action (Iwalokun et al., 2004; Gbenga et al., 2009). Allicin and its derivatives have been
shown to be a larvicidal and bacteriostatic, active against both Gram positive or Gram
negative organisms as well as fungi such as Candida albicans and viruses including
influenza viruses (Chang and Cheong, 2008). Allium sativum taken at a low dose may
have some therapeutics potentials against gastric ulcers associated with
H.

pyloriinfection(Adeniyi et al., 2006). Garlic extracts do have significant inhibitory effects
against microorganisms associated with dental caries (Masaadeh et al., 2006).
When garlic is crushed, its health-promoting properties are released. Allicin is an
antibiotic and an anti-fungal. Garlic also contains Vitamin B, enzymes, minerals and
flavonoids, which attack cancer-causing free-radicals. Garlic's composition offers many
healing possibilities (Paige, 1999).
Raw garlic is more potent; cooking garlic reduces the effect the green, dry 'folds'
in the center of the garlic clove are especially pungent. The sulfur compound allicin,
produced by crushing or chewing fresh garlic, produces other sulfur compounds: ajoene,
allyl sulfides, and vinyldithiins. Aged garlic lacks allicin, but may have some activity due
to the presence of S-allylcysteine. Allicin is released only by crushing or chewing raw
garlic and cannot be formed from cooked garlic.
Garlic may interact with warfarin, antiplatelets, saquinavir, antihypertensives,
calcium channel blockers, and
hypoglycemic
drugs, as well as other
medications.Members of the alium family might be toxic to cats or dogs. Some degree of
liver toxicity has been demonstrated in rats, particularly in extremely large quantities
exceeding those that a rat would consume under normal situations (Wikipedia, 2011).
A study conducted by Raeesiet al., 2010 on the effect of periodical use of Garlic
(alliumsativum) powder on performance and carcasscharacteristics in broiler chickens
showed that birds which received 1 and 3% garlic powder hadgreater weight gain than
those who were fed 0.5% garlicpowder or the control group. The weight gain did not
showsignificant differences between treatments from 0 to 21days.From day 22-42,
treatments which received 1% garlic powder had greater body weight gain than others.

Thesedifferences were significant except between thesetreatments and those which got
0.5% garlic powder.Although birds who received garlic in their finisher diet only had
greater body weight gain than others, period of feedinggarlic (starter, finisher or the
whole of the experiment) had nosignificant effect on body weight gain.In the whole
duration of the experiment (0-42 d), addition of 1 and 3% garlic to basal diets
significantly increased body weight gainas compared with 0.5% garlic supplemented
groups but it was not significant in comparison with control group.Groups which were
fed garlic in the finisher diet had greater body weight gain but, the period of using garlic
did not affect body weight gain significantly.
Feed intake was significantly higher in control group. Birds received garlic for the
whole of theexperiment, had higher feed intake but generally, period offeeding garlic did
not affect feed intake significantly.Chowdhuuryet al., 2002, added different levels of
garlic to layersdiet. They reported no significant effects of thissupplementation on
growth, feed intake and feed efficiency.
Supplementation of 1% garlic powder, decreased feedconversion rate (FCR)
compared with 0.5% supplemented and control group, significantly. Birds received
3%garlic powder in their diets had better FCR than control group.Control groups
significantly consumed more feed than theothers, except those which were supplemented
with 0.5% garlic powder. There were no significant differencesbetween control and 0.5%
supplemented group, although thelatter had lower FCR. Groups which were
supplemented withgarlic powder in just the finisher diet had better FCR thanthose which
were supplemented for the whole of theexperiment. Control groups consumed more feed
than the others but they had no significant difference withthose which supplemented with

garlic in starter diet. Jamrozet al., 2005, reported that capsaicin, cinamaldehyde and
carvacroldecreased FCR significantly in broiler chickens. Howeverthey did not affect
body weight gain at all. Demiret al., 2003, added thyme and garlic powder to broilers
diet. Theyconcluded that this supplementation did not affect growth,feed intake and feed
conversion rate in whole of theexperiment. Konjufcaet al., 1997, reported that
althoughperformance was not affected when broiler diets weresupplemented with 1.5, 3
and 4.5% garlic in powder form,their serum and liver cholesterol decreased significantly.
Theyalso indicated that this supplementation did not influence feedconversion rate. Lewis
et al.,2003, reported that garlic extractincreased body weight gain and also improved
feedconversion rate in broilers between 7-27d. Alciceket al., 2003, indicated that broilers
which received blend of essential oils,had higher weight and feed intake and also lower
feedconversion rate than control group.
In conclusion, 1 and 3% supplemented groups in finisherperiod had better
performance as compared with other groups.Since present study conducted in optimum
and antisepticconditions, it seems that better or more responses could beexpected in
performance if the raising conditions would not behealthy. The authors suggest it needs
more studies to conductin more periods to achieve more accurate results.

METHODOLOGY
Materials
The material that was used were 160 heads of Sunshine Chicken, Commercial
Feeds (CF), Garlic, Antibiotic Premix, Brooding-rearing Cages, Feeders, Waterers,
Sacks, Incandescent Bulb (100 watts), Old Newspaper Sheets, Weighing Scales, Pails,
Record Book, and Disinfectant.
Methodology
Pre-experimental phase. Before the arrival of the chicks, the brooding pens
together with the feeding through and watererswas thoroughly cleaned and disinfected.
The floor was covered with old news paper sheets and the light was switched on a few
hours before the arrival of the chicks.
Upon arrival of the chicks, theywere placed inside the brooder house (Figure 1)
where they were fed with B-Meg Integra 1000. Water was available to them at all times.
During this pre-experimental period which was lasted for five days, the birds were given
the same care and management. They were fed twice a day, once in a morning and once
in the afternoon.
Preparation of garlic supplement. Clean garlic was bought from the market, and
then diced (Figure 2). The resulting product was added on the basal diet of Sunshine
Chicken on specified amounts depending on treatment.

Experimental design and treatment. After 5 days, the experimental birds was
weighed to obtain their initial weight, and was distributed at random into four treatments
following the Completely Randomized Design (CRD) each treatment was replicated
fourtimes with 10 birds per replication, making a total of 40 birds per treatment.
The four treatments were the following:
T0= Commercial Feeds with antibiotic premix in the water (Control)
T1= 15 g Garlic / kg of Commercial Feeds (Figure 3)
T2= 30 g Garlic / kg of Commercial Feeds (Figure 4)
T3= Commercial Feeds with no antibiotic premix

Care and management of birds. The garlic was fed to the birds from six until fifty
six days of age. The birds in all treatments were given the same care and management
except on the levels of garlic that was added to their ration. The birds on the Control (T0)
was fed commercial feeds with antibiotic premix in the water; while the birds that were
assigned to T1was given 15 grams garlic per kilogram of commercial feeds (Figure 3).
The T2 birds were given 30 grams garlic per kilogram of commercial feeds (Figure 4),
and those under T3were given commercial feeds with no antibiotic premix. The birds
were fed with B-Meg Integra 1000 from day 1 up to 14 days, while B-Meg Integra
2000during 15-42 days, and B-Meg Integra 3000from 43 daysto the end of the study at
56 days.

Data Gathered
The data gathered as follows:
1. Initial weight (kg). This refers to the weight of the birds at the start of the study.
This was taken after when the chicks were six days old.
2. Final weight (kg). This refers to the weight of the birds at 56 days of age.
3. Feed offered (kg). This refers to the total amount of feeds consumed by the
birds from the start of the study until the end of the experiment. This was taken by adding
all the feeds offered to the birds after the left-overs have been subtracted.
4. Feed leftover (kg). The weight of the feeds left in the feeding troughs taken
every morning before feeding.
5.
Mortality. This refers to the number of dead birds during the experiment.
6.
Morbidity. This refers to the number of birds that got sick during the duration
of the study.
7. Commercial feed cost. This refers to the cost of commercial feeds.
8. Cost of garlic granules. This refers to the cost ofgarlic.
7. Total feed cost. This refers to the cost of commercial feeds and the garlic.
From the data above, the following data was computed:
1. Total gain in weight (kg). This was computed by subtracting the initial weight
from the final weight.
2. Average daily gain (kg). This was obtained by the following formula:
Average daily gain = Total gain in weight
Experimental period
3. Total feed intake. This was obtained by adding the amount of feed offered after
the feed left-overs had been subtracted.

13
4. Feed conversion ratio. This was obtained by dividing the total feed intake by
the total gain in weight.
5. Feed cost required to produce a kilogram gain in weight. This was obtained by
multiplying the cost of one kilogram feed mixture by the FCR.
6.
Percent
Mortality. This was obtained by dividing the total number of dead birds
in each treatment and multiplied by 100%.
7. Net returns. This was obtained by subtracting the total cost of production from
the total sales.
8. Return on investment (ROI). This was computed using the following formula:
ROI = Total sales - total cost of production x 100
Total cost of production
9. Morbidity rate (%). This was computed by dividing the number of sick birds by
their initial number multiplied by 100.
10.Mortality rate (%). This was obtained by dividing the number of dead birds
from the start until the end of the experiment by the total number of birds at the start of
the study multiplied by 100.
11. Cost of production (php). This includes the cost of stocks, feeds, labor and
other materials that used in the study.
12. Gross income. This was obtained by multiplying the final weight of the birds
by their price per kilogram live weight.
Data Analysis
The data was subjected to analysis of variance for Completely Randomized
Design (CRD). Comparison of treatment means was done using Duncan’s Multiple

RESULTS AND DISCUSSION
Initial Weight
The average initial weights shown in Table 1 were taken when the experimental
birds were 6 days old. Statistical analysis revealed that there were no significant
differences among the treatments. While there are slight differences in the body weights
of the experimental birds presented in the table, such difference were very minimal to
cause a significant difference among the treatments. Result also implies that the
experimental birds had more or less the same in weight at the start of the study. The
average initial weight is 0.380 kg.
Final Weight
The final weights of the sunshine chicken at 56 days of age in all treatments are
also shown in Table 1. The results indicate that the final weights of birds tend to increase
as the level of garlic in the diets was elevated. The birds given 30 g weighed the heaviest.
This was followed by the birds given 15 g garlic and those fed commercial feeds only but
with antibiotic premix in water, respectively. Meanwhile, the weights of the birds fed
commercial feeds with no antibiotic premix were comparable to the two former
treatments. The increase in weights could be attributed to the stimulating effect on the
immune system of the birds and its rich aromatic oils which enhanced their digestion as
cited by Gardzielewskaet al. (2003).
Total Gain in Weight
Table 2 presents the total gain in weight of the birds in the different treatments.
Statistical analysis shows highly significant differences among the treatment means.

Thirty grams of garlic supplementation resulted to a mean gain of 2.077 kg, same with
the group fed with fifteen grams which is 1.952. The group fed with commercial feeds
and lastly the one fed with commercial feeds with antibiotic premix in the water had
comparable means which were lower than the above mentioned means.This collaborates
with the study of Raeesiet al. which found that the addition of 1 and 3% garlic to basal
diets of broilers significantly increased body weight gain as compared with 0.5% garlic
supplemented groups. This implies that adding garlic granules on the feeds of the birds
positively affects the growth performance of the birds. The result revealed that
supplementing 15 to 30 grams garlic granules on sunshine chicken ration improves body
weight gain.
Average Daily Gain
Thedifferences between the average daily gain in weight of the birds compared
among treatments were highly significant, wherein the experimental birds given with
15to 30 grams garlic were found more capable to gain weight daily than those given
commercial feeds only with or without antibiotic premix as shown in Table 2.

Total Feed Intake
The average feed consumption of the birds is shown in Table 3. Statistical
analysis showed there were no significant differences among the different treatments.
This is similar to the study of Chowdhuury et al., where they added different levels of
garlic to layers diet where they reported no significant effects of supplementation on feed
intake. This means that all the experimental birds have eaten more or less the same
amount of feeds. This implies that the garlic incorporated with the ration of the
experimental birds was very minimal and did not significantly increase the feed
consumption of the birds.
Feed Conversion Ratio
Table 4likewise presents feed conversion ratio of the treatments. Statistical
analysis showed significant differences between treatments. The birds given 30 grams
ofantibiotic premix on water.On the other hand, the feed conversion ratio of the birds fed
15 g garlic was comparable to that of the birds given commercial feeds with no antibiotic
premix. This result was similarly reported byRaeesiet al., where the birds which

received 3% garlic powder in their diets had better FCR than control group. This
indicates that the addition of garlic on the feeds makes them more efficient in converting
feeds to flesh. The overall mean feed conversion ratio of the birds was 2.567. These could
be possibly caused by capsaicin, cinamaldehyde and carvacrol which improved FCR in
broiler chickens as reported by Jamrozet al.

weight. Statistical analysis showed that there was a highly significant difference among
the treatmentmeans. The birds given the highest amount of garlic (30 grams) has a higher
feed cost to produce kilogram gain in weight. There was a direct relationship between the
levels ofgarlic and the cost of feed to produce a kilogram gain due to the additional cost
incurred in the procurement of the garlic.
Morbidity Rate
Two birds got sick when they were 11 days old.However, at 21 days age it was
observed that the swollen and teary eyes got healed. Furthermore, birds given antibiotic
premix on water was the only group which had a morbidity rate of 5 %. This mayproves
that garlic is a plant with antibiotic, anticancer, antioxidant, immunomodulatory, anti-
inflammatory, hypoglycemic and cardiovascular- protecting effects.
Mortality Rate
Two birds died during the duration of the study. The group fed commercial feeds
with antibiotic premix in the water has 2.5% mortality rate similar with the group fed

with commercial feeds without antibiotic. The first bird that died was from the
groupgiven commercial feeds with no antibiotic 42 days of age. The other bird died at 43
days of age from the group that fed with commercial feed with antibiotic premix. They
were suspected to have died because of heat stroke.
Return on Investment
Table 7 shows the return on investment in the different treatments. Even though it
was not subjected to statistical analysis, it is shown that the group fed with 30 g garlic has
a higher ROI of 31.71% followed by the group given 15 g of garlic having 26.50%. The
group fed commercial feeds without antibiotic, and the group fed commercial feeds with
antibiotic premix on the water recovered lower ROI. This implies that supplementing
garlic on the feed of chicken may result to a higher income.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to determine the effect of different levels of garlic on
the growth performance of Sunshine Chicken. One hundred sixty day-old chicks were
distributed at random following the Completely Randomized Design (CRD) into four
treatments. Each treatment was replicated four times with ten birds per replication,
making a total of 40 per treatment. The treatment were: T0-Commercial Feeds with
antibiotic premix in the water, T1-15g garlic / kg of Commercial Feeds, T2-30 g garlic /
kg of Commercial Feeds, and T3-Commercial Feeds with no antibiotic premix. This was
conducted from October to December, 2011 at Benguet State University Poultry
Experimental House at Balili, La Trinidad, Benguet.
Analysis of variance showed no significant differences in terms of initial weight
and total feed intake. However, the feed conversion ratio of the birds fed with garlic
relatively improved. The same effect was seen on the final weight, total gain, and feed
cost per kilogram gain in weight.
This shows that supplementation of 15-30 grams garlic may cause the birds to
gain more weight than those group fed with commercial feeds with antibiotic premix on
water and commercial feeds only. It did not lower the feed consumption of the birds but it
has made them more efficient in converting feed to flesh.
Though there were morbidity from the group fed commercial feeds with antibiotic
premix on the water and mortality from the group fed with 15 grams garlicandthose given
only commercialfeeds only, the values were low and thus did not affect the ROI. This
means that adding 30 grams garlic on the basal diet may have been effective in keeping

the birds healthy since there was no mortality like the control group given commercial
antibiotic.
The highest return on investment was observed in the birds given 30 grams garlic
followed by the group fed with 15 grams,commercial feeds only with no antibiotic and
lastly, the group given antibiotic premix on the water.
Conclusion
Based on the results of the study, the addition of garlic on the sunshine chicken
ration resulted to higher body weights and weight gain, better FCR and lower feed
conversion ratio, and total feed cost to produce a kilogram in weight. Therefore, it is
concluded that garlic can be incorporated in the feed of sunshine chickens to enhance
growth and feed efficiency.
Recommendation
Since supplementing garlic on sunshine chicken ration resulted to higher income,
it is recommended that garlic may be added in sunshine chicken diets during the
brooding-finishing period.
However, a similar study may be conducted to evaluate the effect if the level of
garlic is increased beyond 30g.

ABSTRACT
The study was conducted at the Benguet State University experimental project
from October to December 2011to compare the level of garlicand with antibiotic premix
on water on the growth performance of sunshine chicken, feed consumption, feed
efficiency, morbidity and mortality, and lastly on the return of investment.
A total of 160 Sunshine Chicken day old chicks were randomly distributed after
having a 5 day trial feeding into four treatments following the Complete Randomized
Design (CRD). The four treatments were replicated four times with ten birds per
replicate.
The result and observation showed after 56 days of the experiment that there were
no significant in terms of the initial weight and total feed intake. While on the feed
conversion ratio it was shown that it is significant same as through on the final weight,
total feed intake, average daily gain, and total feed cost required to produce a kilogram in
weight which has a result of highly significant.
Apparently, the treated sunshine chicken with 30 grams of garlic granules has a
better effect when it comes to its final weight, total gain in weight, average daily gain and
on the return on investment which has a higher percentage than those of the other
treatments of 31.75 %.

INTRODUCTION
Animal raising is an important and diverse component of Philippines Agriculture
and one of it is poultry production which is a practice of raising domesticated birds, for
the purpose of meat and egg as a part of our diet.
Feeding has a great effect in the growth of poultry industry and almost research
now a day is focused on finding new supplement that improves animal performance
that’s why it is important to the raisers to know what the best feed is for their bird is. And
we know the fact that chickens are omnivores, eating most anything they find. This eating
habit of chicken makes them easy to feed a variety of supplemental feed. Though
commercial feed provides a good base diet for chicken, it is still efficient if we add an
herbal supplement on their diet which could boost its growth performance that will
increase our profit.
This study allows us to improve more on chicken traits such as performance, and
immune response. It was also conducted to find out the effect of garlic granules as a feed
supplement to sunshine chickens. The result of this study can serve as a guide in using
garlic granules as a feed supplement in chickens.Lastly, the research can be a good start
to enhance the performance of chickens that can result to high income and profit.
The Studyspecifically aimed todetermine the effect of garlic in terms of: growth
performance, feed consumption, feed efficiency, morbidity and mortality of chickens, and
return on investment. And to determine the best level of granulated garlic to be utilized as
feed supplement for sunshine chicken.
This study was conducted at the Benguet State University (BSU) Poultry
Experimental House Balili, La Trinidad, Benguet.

REVIEW OF LITERATURE
Chicken broiler and egg production are the most progressive animal enterprises in
the Philippines today. The poultry industry in fact began as a backyard enterprise but has
shifted to the formation of very large integrated contract farming operations. The growth
of poultry industry in the Philippines has indeed been impressive but its problems
including inefficient management and the prevalence of many destructive poultry
diseases and parasites cannot be ignored (EPA, 2005).
The practice of complementary and alternative medicine is now on the increase in
developing countries in response to World Health Organization directives culminating in
several pre-clinical and clinical studies that have provided the scientific basis for the
efficacy of many plants used in folk medicine to treat infections (Vijaya and Ananthan,
1997; Dilhuydy and Patients, 2003; Iwalokun et al., 2004). Previous studies have
demonstrated positive effects of herbal supplements on production performance and
carcass quality to chickens (Schleicher et al., 1998; Tekeli et al., 2006, 2008).
In pursuit of improved broilers health and in order to fulfill consumer expectation
in relation to food quality, poultry producers commonly apply natural feeding
supplements, mainly herbs (Gardzielewska et al., 2003).
Garlic is one of the most beneficial natural food supplements. This is because of
garlic's numerous significant health benefits. First of all, garlic helps to detoxify the body
while enhancing the immune system. This makes garlic beneficial for fighting colds and
infections. Garlic also is well known as a natural way to lower blood pressure while
improving circulation. However, the benefits of garlic don't stop here. Garlic lowers
blood lipid levels, helps to stabilize blood sugar levels, and may even help prevent ulcers.

Garlic is helpful for virtually any disease or infection, making it one of the most popular
herbal food supplements (Anonymous, 2007).
Garlic, a member of the Allium family (Liliaceae), has been used traditionally for
ages to treat a wide array of diseases, namely, respiratory infections, ulcers, diarrhea and
skin infections (Fenwick and Hanley, 1985). Reuter et al. (1996) reported garlic as a
plant with antibiotic, anticancer, antioxidant, immunomodulatory, anti-inflammatory,
hypoglycemic and cardiovascular- protecting effects.
Moreover, garlic is very rich in aromatic oils, which enhance digestion and
positively influenced respiratory system being inhaled into air sacs and lungs of birds.
Also it was found that garlic has strong antioxidative effects (Gardzielewska et al., 2003).
Garlic extract and/or garlic components were able to prevent chemically induced
tumors or acute toxic effects of chemicals. The chemo-preventive potential of garlic has
been attributed to the presence of several bioactive organosulfur compounds. These
compounds might act as antioxidants (Fanelli et al., 1998; Siegers et al., 1999). The
antioxidative stress properties of garlic might result from the contributions of its sulfur
component in different steps and not necessarily from the contribution of only one of
them (Fanelli et al., 1998). Garlic also has been shown to have strong antimicrobial
action (Iwalokun et al., 2004; Gbenga et al., 2009). Allicin and its derivatives have been
shown to be a larvicidal and bacteriostatic, active against both Gram positive or Gram
negative organisms as well as fungi such as Candida albicans and viruses including
influenza viruses (Chang and Cheong, 2008). Allium sativum taken at a low dose may
have some therapeutics potentials against gastric ulcers associated with

pyloriinfection(Adeniyi et al., 2006). Garlic extracts do have significant inhibitory effects
against microorganisms associated with dental caries (Masaadeh et al., 2006).
When garlic is crushed, its health-promoting properties are released. Allicin is an
antibiotic and an anti-fungal. Garlic also contains Vitamin B, enzymes, minerals and
flavonoids, which attack cancer-causing free-radicals. Garlic's composition offers many
healing possibilities (Paige, 1999).
Raw garlic is more potent; cooking garlic reduces the effect the green, dry 'folds'
in the center of the garlic clove are especially pungent. The sulfur compound allicin,
produced by crushing or chewing fresh garlic, produces other sulfur compounds: ajoene,
allyl sulfides, and vinyldithiins. Aged garlic lacks allicin, but may have some activity due
to the presence of S-allylcysteine. Allicin is released only by crushing or chewing raw
garlic and cannot be formed from cooked garlic.
Garlic may interact with warfarin, antiplatelets, saquinavir, antihypertensives,
calcium channel blockers, and
hypoglycemic
drugs, as well as other
medications.Members of the alium family might be toxic to cats or dogs. Some degree of
liver toxicity has been demonstrated in rats, particularly in extremely large quantities
exceeding those that a rat would consume under normal situations (Wikipedia, 2011).
A study conducted by Raeesiet al., 2010 on the effect of periodical use of Garlic
(alliumsativum) powder on performance and carcasscharacteristics in broiler chickens
showed that birds which received 1 and 3% garlic powder hadgreater weight gain than
those who were fed 0.5% garlicpowder or the control group. The weight gain did not
showsignificant differences between treatments from 0 to 21days.From day 22-42,
treatments which received 1% garlic powder had greater body weight gain than others.

Thesedifferences were significant except between thesetreatments and those which got
0.5% garlic powder.Although birds who received garlic in their finisher diet only had
greater body weight gain than others, period of feedinggarlic (starter, finisher or the
whole of the experiment) had nosignificant effect on body weight gain.In the whole
duration of the experiment (0-42 d), addition of 1 and 3% garlic to basal diets
significantly increased body weight gainas compared with 0.5% garlic supplemented
groups but it was not significant in comparison with control group.Groups which were
fed garlic in the finisher diet had greater body weight gain but, the period of using garlic
did not affect body weight gain significantly.
Feed intake was significantly higher in control group. Birds received garlic for the
whole of theexperiment, had higher feed intake but generally, period offeeding garlic did
not affect feed intake significantly.Chowdhuuryet al., 2002, added different levels of
garlic to layersdiet. They reported no significant effects of thissupplementation on
growth, feed intake and feed efficiency.
Supplementation of 1% garlic powder, decreased feedconversion rate (FCR)
compared with 0.5% supplemented and control group, significantly. Birds received
3%garlic powder in their diets had better FCR than control group.Control groups
significantly consumed more feed than theothers, except those which were supplemented
with 0.5% garlic powder. There were no significant differencesbetween control and 0.5%
supplemented group, although thelatter had lower FCR. Groups which were
supplemented withgarlic powder in just the finisher diet had better FCR thanthose which
were supplemented for the whole of theexperiment. Control groups consumed more feed
than the others but they had no significant difference withthose which supplemented with

garlic in starter diet. Jamrozet al., 2005, reported that capsaicin, cinamaldehyde and
carvacroldecreased FCR significantly in broiler chickens. Howeverthey did not affect
body weight gain at all. Demiret al., 2003, added thyme and garlic powder to broilers
diet. Theyconcluded that this supplementation did not affect growth,feed intake and feed
conversion rate in whole of theexperiment. Konjufcaet al., 1997, reported that
althoughperformance was not affected when broiler diets weresupplemented with 1.5, 3
and 4.5% garlic in powder form,their serum and liver cholesterol decreased significantly.
Theyalso indicated that this supplementation did not influence feedconversion rate. Lewis
et al.,2003, reported that garlic extractincreased body weight gain and also improved
feedconversion rate in broilers between 7-27d. Alciceket al., 2003, indicated that broilers
which received blend of essential oils,had higher weight and feed intake and also lower
feedconversion rate than control group.
In conclusion, 1 and 3% supplemented groups in finisherperiod had better
performance as compared with other groups.Since present study conducted in optimum
and antisepticconditions, it seems that better or more responses could beexpected in
performance if the raising conditions would not behealthy. The authors suggest it needs
more studies to conductin more periods to achieve more accurate results.

METHODOLOGY
Materials
The material that was used were 160 heads of Sunshine Chicken, Commercial
Feeds (CF), Garlic, Antibiotic Premix, Brooding-rearing Cages, Feeders, Waterers,
Sacks, Incandescent Bulb (100 watts), Old Newspaper Sheets, Weighing Scales, Pails,
Record Book, and Disinfectant.
Methodology
Pre-experimental phase. Before the arrival of the chicks, the brooding pens
together with the feeding through and watererswas thoroughly cleaned and disinfected.
The floor was covered with old news paper sheets and the light was switched on a few
hours before the arrival of the chicks.
Upon arrival of the chicks, theywere placed inside the brooder house (Figure 1)
where they were fed with B-Meg Integra 1000. Water was available to them at all times.
During this pre-experimental period which was lasted for five days, the birds were given
the same care and management. They were fed twice a day, once in a morning and once
in the afternoon.
Preparation of garlic supplement. Clean garlic was bought from the market, and
then diced (Figure 2). The resulting product was added on the basal diet of Sunshine
Chicken on specified amounts depending on treatment.

Experimental design and treatment. After 5 days, the experimental birds was
weighed to obtain their initial weight, and was distributed at random into four treatments
following the Completely Randomized Design (CRD) each treatment was replicated
fourtimes with 10 birds per replication, making a total of 40 birds per treatment.
The four treatments were the following:
T0= Commercial Feeds with antibiotic premix in the water (Control)
T1= 15 g Garlic / kg of Commercial Feeds (Figure 3)
T2= 30 g Garlic / kg of Commercial Feeds (Figure 4)
T3= Commercial Feeds with no antibiotic premix

Care and management of birds. The garlic was fed to the birds from six until fifty
six days of age. The birds in all treatments were given the same care and management
except on the levels of garlic that was added to their ration. The birds on the Control (T0)
was fed commercial feeds with antibiotic premix in the water; while the birds that were
assigned to T1was given 15 grams garlic per kilogram of commercial feeds (Figure 3).
The T2 birds were given 30 grams garlic per kilogram of commercial feeds (Figure 4),
and those under T3were given commercial feeds with no antibiotic premix. The birds
were fed with B-Meg Integra 1000 from day 1 up to 14 days, while B-Meg Integra
2000during 15-42 days, and B-Meg Integra 3000from 43 daysto the end of the study at
56 days.

Data Gathered
The data gathered as follows:
1. Initial weight (kg). This refers to the weight of the birds at the start of the study.
This was taken after when the chicks were six days old.
2. Final weight (kg). This refers to the weight of the birds at 56 days of age.
3. Feed offered (kg). This refers to the total amount of feeds consumed by the
birds from the start of the study until the end of the experiment. This was taken by adding
all the feeds offered to the birds after the left-overs have been subtracted.
4. Feed leftover (kg). The weight of the feeds left in the feeding troughs taken
every morning before feeding.
5.
Mortality. This refers to the number of dead birds during the experiment.
6.
Morbidity. This refers to the number of birds that got sick during the duration
of the study.
7. Commercial feed cost. This refers to the cost of commercial feeds.
8. Cost of garlic granules. This refers to the cost ofgarlic.
7. Total feed cost. This refers to the cost of commercial feeds and the garlic.
From the data above, the following data was computed:
1. Total gain in weight (kg). This was computed by subtracting the initial weight
from the final weight.
2. Average daily gain (kg). This was obtained by the following formula:
Average daily gain = Total gain in weight
Experimental period
3. Total feed intake. This was obtained by adding the amount of feed offered after
the feed left-overs had been subtracted.

13
4. Feed conversion ratio. This was obtained by dividing the total feed intake by
the total gain in weight.
5. Feed cost required to produce a kilogram gain in weight. This was obtained by
multiplying the cost of one kilogram feed mixture by the FCR.
6.
Percent
Mortality. This was obtained by dividing the total number of dead birds
in each treatment and multiplied by 100%.
7. Net returns. This was obtained by subtracting the total cost of production from
the total sales.
8. Return on investment (ROI). This was computed using the following formula:
ROI = Total sales - total cost of production x 100
Total cost of production
9. Morbidity rate (%). This was computed by dividing the number of sick birds by
their initial number multiplied by 100.
10.Mortality rate (%). This was obtained by dividing the number of dead birds
from the start until the end of the experiment by the total number of birds at the start of
the study multiplied by 100.
11. Cost of production (php). This includes the cost of stocks, feeds, labor and
other materials that used in the study.
12. Gross income. This was obtained by multiplying the final weight of the birds
by their price per kilogram live weight.
Data Analysis
The data was subjected to analysis of variance for Completely Randomized
Design (CRD). Comparison of treatment means was done using Duncan’s Multiple

RESULTS AND DISCUSSION
Initial Weight
The average initial weights shown in Table 1 were taken when the experimental
birds were 6 days old. Statistical analysis revealed that there were no significant
differences among the treatments. While there are slight differences in the body weights
of the experimental birds presented in the table, such difference were very minimal to
cause a significant difference among the treatments. Result also implies that the
experimental birds had more or less the same in weight at the start of the study. The
average initial weight is 0.380 kg.
Final Weight
The final weights of the sunshine chicken at 56 days of age in all treatments are
also shown in Table 1. The results indicate that the final weights of birds tend to increase
as the level of garlic in the diets was elevated. The birds given 30 g weighed the heaviest.
This was followed by the birds given 15 g garlic and those fed commercial feeds only but
with antibiotic premix in water, respectively. Meanwhile, the weights of the birds fed
commercial feeds with no antibiotic premix were comparable to the two former
treatments. The increase in weights could be attributed to the stimulating effect on the
immune system of the birds and its rich aromatic oils which enhanced their digestion as
cited by Gardzielewskaet al. (2003).
Total Gain in Weight
Table 2 presents the total gain in weight of the birds in the different treatments.
Statistical analysis shows highly significant differences among the treatment means.

Thirty grams of garlic supplementation resulted to a mean gain of 2.077 kg, same with
the group fed with fifteen grams which is 1.952. The group fed with commercial feeds
and lastly the one fed with commercial feeds with antibiotic premix in the water had
comparable means which were lower than the above mentioned means.This collaborates
with the study of Raeesiet al. which found that the addition of 1 and 3% garlic to basal
diets of broilers significantly increased body weight gain as compared with 0.5% garlic
supplemented groups. This implies that adding garlic granules on the feeds of the birds
positively affects the growth performance of the birds. The result revealed that
supplementing 15 to 30 grams garlic granules on sunshine chicken ration improves body
weight gain.
Average Daily Gain
Thedifferences between the average daily gain in weight of the birds compared
among treatments were highly significant, wherein the experimental birds given with
15to 30 grams garlic were found more capable to gain weight daily than those given
commercial feeds only with or without antibiotic premix as shown in Table 2.

Total Feed Intake
The average feed consumption of the birds is shown in Table 3. Statistical
analysis showed there were no significant differences among the different treatments.
This is similar to the study of Chowdhuury et al., where they added different levels of
garlic to layers diet where they reported no significant effects of supplementation on feed
intake. This means that all the experimental birds have eaten more or less the same
amount of feeds. This implies that the garlic incorporated with the ration of the
experimental birds was very minimal and did not significantly increase the feed
consumption of the birds.
Feed Conversion Ratio
Table 4likewise presents feed conversion ratio of the treatments. Statistical
analysis showed significant differences between treatments. The birds given 30 grams
ofantibiotic premix on water.On the other hand, the feed conversion ratio of the birds fed
15 g garlic was comparable to that of the birds given commercial feeds with no antibiotic
premix. This result was similarly reported byRaeesiet al., where the birds which

received 3% garlic powder in their diets had better FCR than control group. This
indicates that the addition of garlic on the feeds makes them more efficient in converting
feeds to flesh. The overall mean feed conversion ratio of the birds was 2.567. These could
be possibly caused by capsaicin, cinamaldehyde and carvacrol which improved FCR in
broiler chickens as reported by Jamrozet al.

weight. Statistical analysis showed that there was a highly significant difference among
the treatmentmeans. The birds given the highest amount of garlic (30 grams) has a higher
feed cost to produce kilogram gain in weight. There was a direct relationship between the
levels ofgarlic and the cost of feed to produce a kilogram gain due to the additional cost
incurred in the procurement of the garlic.
Morbidity Rate
Two birds got sick when they were 11 days old.However, at 21 days age it was
observed that the swollen and teary eyes got healed. Furthermore, birds given antibiotic
premix on water was the only group which had a morbidity rate of 5 %. This mayproves
that garlic is a plant with antibiotic, anticancer, antioxidant, immunomodulatory, anti-
inflammatory, hypoglycemic and cardiovascular- protecting effects.
Mortality Rate
Two birds died during the duration of the study. The group fed commercial feeds
with antibiotic premix in the water has 2.5% mortality rate similar with the group fed

with commercial feeds without antibiotic. The first bird that died was from the
groupgiven commercial feeds with no antibiotic 42 days of age. The other bird died at 43
days of age from the group that fed with commercial feed with antibiotic premix. They
were suspected to have died because of heat stroke.
Return on Investment
Table 7 shows the return on investment in the different treatments. Even though it
was not subjected to statistical analysis, it is shown that the group fed with 30 g garlic has
a higher ROI of 31.71% followed by the group given 15 g of garlic having 26.50%. The
group fed commercial feeds without antibiotic, and the group fed commercial feeds with
antibiotic premix on the water recovered lower ROI. This implies that supplementing
garlic on the feed of chicken may result to a higher income.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to determine the effect of different levels of garlic on
the growth performance of Sunshine Chicken. One hundred sixty day-old chicks were
distributed at random following the Completely Randomized Design (CRD) into four
treatments. Each treatment was replicated four times with ten birds per replication,
making a total of 40 per treatment. The treatment were: T0-Commercial Feeds with
antibiotic premix in the water, T1-15g garlic / kg of Commercial Feeds, T2-30 g garlic /
kg of Commercial Feeds, and T3-Commercial Feeds with no antibiotic premix. This was
conducted from October to December, 2011 at Benguet State University Poultry
Experimental House at Balili, La Trinidad, Benguet.
Analysis of variance showed no significant differences in terms of initial weight
and total feed intake. However, the feed conversion ratio of the birds fed with garlic
relatively improved. The same effect was seen on the final weight, total gain, and feed
cost per kilogram gain in weight.
This shows that supplementation of 15-30 grams garlic may cause the birds to
gain more weight than those group fed with commercial feeds with antibiotic premix on
water and commercial feeds only. It did not lower the feed consumption of the birds but it
has made them more efficient in converting feed to flesh.
Though there were morbidity from the group fed commercial feeds with antibiotic
premix on the water and mortality from the group fed with 15 grams garlicandthose given
only commercialfeeds only, the values were low and thus did not affect the ROI. This
means that adding 30 grams garlic on the basal diet may have been effective in keeping
Growth Performance of Sunshine Chicken Given Garlic (Allium sativum) as

the birds healthy since there was no mortality like the control group given commercial
antibiotic.
The highest return on investment was observed in the birds given 30 grams garlic
followed by the group fed with 15 grams,commercial feeds only with no antibiotic and
lastly, the group given antibiotic premix on the water.
Conclusion
Based on the results of the study, the addition of garlic on the sunshine chicken
ration resulted to higher body weights and weight gain, better FCR and lower feed
conversion ratio, and total feed cost to produce a kilogram in weight. Therefore, it is
concluded that garlic can be incorporated in the feed of sunshine chickens to enhance
growth and feed efficiency.
Recommendation
Since supplementing garlic on sunshine chicken ration resulted to higher income,
it is recommended that garlic may be added in sunshine chicken diets during the
brooding-finishing period.
However, a similar study may be conducted to evaluate the effect if the level of
garlic is increased beyond 30g.
