ABSTRACT
The study was conducted at the BSU Experimental Station, La Trinidad, Benguet from May to June
2011 to determine the effect of Atovi supplementation on the growth performance of Cobb broilers.
A total of 80 day-old chicks were randomly distributed into two treatments and each
treatment was replicated four times with ten birds per replicate to make a total of 40 birds per
treatment. The two treatments were pure water or no Atovi supplementation and 2.5 g of Atovi per
liter of water. The Atovi supplementation was introduced to the birds at day 7 to 14 days but the
end of the study is at 40 days old.
Results showed that there were no significant differences in the initial weight, gain in
weight, feed conversion ratio and feed cost to produce a kilogram gain in weight. The average daily
gain in weight of the birds has a mean of 0.029 kg. It is revealed that the birds given 2.5 g 0f Atovi
per liter of water had the same performance as those of the control group in terms of final weight,
water and feed consumption. In terms of feed conversion ratio, it is revealed that birds given Atovi
and the control group had the same efficiency in converting feeds into flesh. The mean feed
conversion ratio of birds is 1.754
No incidence of mortality nor morbidity was incurred in all treatments which could possibly
mean that Atovi was efficient in improving the immune system of the birds that made them to have
a greater stamina to combat diseases caused by bacteria and viruses compared to the birds in the
control group given vetracin. In terms of the return on investment birds given Atovi had the higher
return.

The Effects of Atovi Supplementation on the Growth Performance
of Cobb Broilers /Resalie T. Mangawa. 2012
INTRODUCTION
Broiler production is one of the most developed animal industries. It is not only a
means of solving meat inadequacy, being an excellent source of protein, but it is also one
of the major sources of livelihood for some farmers because it generates profit in a short
period of time. Nowadays, most poultry raisers use feed additives to increase production
of poultry products. However, poultry raisers should choose a feed supplement or
additive containing better nutritive value suited to their animals which may be given in
small amount but functions greatly in the growth development of the animal body. One of
the newly introduced feed additives which, according to the manufacturer, improve the
performance of the livestock and poultry when added into their feed and/or water intake
is the Atovi and this is what the researcher would like to find out in this study i.e. the
effect of Atovi on the growth performance of broilers.
Atovi, according to the Vim-Vertex& Company, Inc. (2007), the manufacturer, is
a Filipino invented product based on molecular alteration, nuclear reaction and
nanotechnology. It is a feed premix powder made from vitamins and minerals.
The Vim-Vertex & Company, Inc. as cited in www.atovianimalg2.com(2007),
also claimed that the Atovi’s high micro potential energy charges the cells mitochondria
and immediately initiates the ATP pumps to run the Krebs cycle (cells whole mechanism)
that is all cells of all organs i.e. liver, kidneys, heart. Intestinal tract, muscles, bones,
etc.at all levels of the animal, making normal cells efficient while the deteriorating and
sickly cells revitalized, rejuvenated and restored ultimately making them efficient too.
Ones the body cells are efficient; they automatically regenerate and increase the immune
system and anti-bodies.

Also it was cited that Atovi corrects and maintains the digestive system properly.
Though this all nutritional and medication inputs are absorbed and utilized properly and
efficiently. Proof of this is the almost total absence of undigested proteins in the manure
and very low ammonia fumes which produce the foul odor ending up into a non-
pathogenic and organic fecal and further decomposition is not needed.
With metabolism performing properly, the genetic potentials and performance,
like that of the immune system are strengthened. The animals have greater stamina. They
do not easily contract disease caused by bacteria and viruses. In cases where medications
have to be administered such medicines are readily absorbed and utilized ensuring faster
recovery.
The result of the study will benefit both the researcher and the broiler raiser in
particular and also the broiler industry as a whole. If the result is found feasible, broiler
user may use Atovi as a feed supplement to improve the performance of the birds. The
result may also serve as reference materials for other students and researchers to come up
with follow-up researches.
The study was conducted at the BSU Experimental Station, La Trinidad, Benguet
using a total of 80 Cobb broiler subjected to 40 days of feeding period from May to June
2011. Generally, the study was conducted to determine the effect of Atovi
supplementation on the growth performance of broilers under upland condition.
Specifically, it aimed to determine the performance of broilers given Atovi in terms of
gain in weight, feed and water consumptions, feed conversion ratio, morbidity and
mortality rates, and net profit.

REVIEW OF LITERATURE
West (1977) defined feed additive as a substance added to compound ration or
protein concentrate in the course of manufacturing, for some specific functions such as,
stimulates growth and improves the efficiency of feed utilization.
Gillespie (1979) cited that feed additives are drug like materials added to basic
feed mix. Feed additives are not nutrients; they are added to feed mix to cause animals to
grow faster or to control some diseases. Similarly, Fronda (1972) mentioned that using
feed additive does not only make production of animals economical but also helps in the
control of diseases.
Card and Nesheim (1972) said that the addition of additives in poultry feeds will
often improve the rate of weight gain and feed efficiency of growing chicks and provide
the entire essential in adequate amount.
Lassiter and Edwards (1982) mentioned that additives are substances added to
feeds that are not included for their nutritional value but in one way or the other will
improve animal performance or efficiency of animal production.
Acker (1983) cited that wide acceptance of feed additives in poultry and swine
ration is attributed to their well-established benefit in improving growth rate, improving
feed conversion and reducing mortality and morbidity. He also stated that materials serve
as catalyst in digestion and metabolism in very small amount. Furthermore, he also
mentioned that the rearing of animals such as broilers in confinement increases the need
of vitamins in rations.
Atovi, according to the Vim-Vertex & Company, Inc. (2007) is made from
vitamins and minerals feed premix that improves the performance and efficiency of a cell

Atovi induces natural detoxification or expulsion of harmful compounds or
xenobiotics such as drugs, natural poisons and antibiotics on the cellular level. The
benefits attained in using Atovi feed premix are as follows:increaseoutput& productivity,
reduces feed intake, reduces redundant nutritional supplements and medication, reduces
consumption of water and power, eco-friendly manures and wastes because it does that
not emit foul odor and does not pollute the land, air & water. www.alibaba.com (2007).

MATERIALS AND METHOD
The materials and equipment used were: 80 day old broiler chicks (Cobb),
weighing scale, measuring cups, spoon, stick brooms, disinfectant, incandescent bulbs,
old newspaper sheets, brooding and rearing cages, record book, feeding and drinking
troughs, Atovi and commercial feeds (purina).
All the brooding and rearing cages were thoroughly cleaned with laundry soaps
and disinfected a week before the arrival of the chicks. Newspaper sheets were placed on
the floor to minimize the escape of heat inside the brooder and to serve as mattings. Also,
it served as receptacle for feeds for the first few days. In addition, waterers were well
secured on the floor to minimize spillage and these were covered with wire screen to
prevent the birds from stepping inside the waterer. Furthermore, the brooders were heated
two hours before the arrival of the chicks.
Upon arrival, the 80 birds were divided into two treatments following the T-Test.
Each treatment had four replications with 10 birds per replicate, making a total of 40
birds per treatment group. The two treatments were:
T0= pure water/ no Atovi
T1= 2.5g Atovi per liter of water
All birds were subjected to the same management except on the drinking water
offered to them. Birds in the control group (T0) were given pure water withvetracin for
the first two weeks but with no supplementation of Atovi. Birds in treatment (T1) were
given Atovi supplementation at the level of 2.5 g per liter of water but without vetracin
for the first two weeks. The Atovi supplementation was introduced to the birds at day 7
until they were 40 days old.

Feeding was done 4 times a day, at 6 and 10 o’clock in the morning and 2 and 6
o’clock in the afternoon. During the first two weeks of brooding, the chicks were fed with
chick booster containing 24% of crude protein. This was followed by broiler starter mash
for the next two weeks (15th-30th) containing 21% crude protein, and then finisher ration
containing 18% crude protein on the remaining weeks until the end of the study or at 40
days old.
Birds in all treatment were also subjected to the same lighting management.
Brooding cages were lighted day and night. However, lights were turned off for a period
of one hour daily at 5-6:00 pm for the birds to be accustomed to the dark surrounding in
case of brown outs. But during the conduct of the study, there were no brown outs
incurred.
To help maintain the good health of the birds, hygiene and sanitation were
maintained to avoid the occurrence of diseases. Manures of the birds were scrapped daily.
Also, the birds were vaccinated against avian pest on the 10th day of brooding.

RESULTS AND DISCUSSION
Body Weights
Table 1 presents the mean initial and final weights of the birds in the two
treatments. Statistical analysis revealed that the initial weights of the birds in the two
treatments were not significantly different. This implies that the birds were more or less
of the same weight at the start of the study. The birds had an overall mean initial weight
of 0.453 kg.
In terms of final weight, statistical analysis revealed a highly significant
difference between treatment means. The mean final weight of birds given Atovi were
heavier with a mean of 1.67 kg compared to the mean final weight of birds given pure
water or no Atovi supplementation which was 1.546 kg.
Total Gain in Weight
The total gains in weight of the birds in the two treatments are presented in Table
2. Statistical analysis revealed that the gains in weight of the birds in the two treatments
were not significantly different.Thebirds given Atovi had a mean gain in wieght of 1.220
kg and the birds given pure water or no Atovi supplementation had a mean of 1.091 kg.
This implies that adding Atovi into the water of birds did not stimulate the growth of the
birds. This finding is different from the claim of the

manufacturer, the Vim-Vertex & Company, Inc., that Atovi premix, when given to the
birds, improves their growth rate.
Feed and Water Consumption
The mean feed and water consumptions of the birds in the two treatments are
presented in Table 3. True to both feed and water consumptions, significant differences
were observed between the two treatments. Birds given Atovi supplementation consumed
more feeds and water with means of 2.154 kg and 1.537 l, respectively. On the other
hand, the birds in the control group or those not given Atovi supplementation had a mean
feed consumption of 1.1885 kg and a mean water consumption of 1.535 l. The result
implies that giving Atovi to the birds increases their feed and water consumptions.
Perhaps the Atovi had made the feed and water palatable, hence, the increase on their
consumptions.

Feed Conversion Ratio (FCR)
The mean feed conversion ratios of the birds in the two treatments are presented
in Table 4. Statistical analysis revealed that there was no significant difference between
the two treatment means indicating that giving Atovi to the birds did not affect their feed
conversion ratio. The overall mean feed conversion ratio obtained was 1.754.
Morbidity and Mortality
There was no incidence of mortality or morbidity among the birds from the start
up to the end of the study. Even if the treated birds were just given Atovi and were not
given commercial vetracin as done to the control birds, these were able to maintain good
health despite the fluctuation of the environmental temperature that could have made the
birds prone to respiratory diseases during the conduct of the study. These could possibly
mean that Atovi given to the treated bird was efficient in enhancing the immune system
of the birds or it had made them to have a greater stamina to combat diseases caused by
bacteria and viruses. The result agrees with Acker (1983) who stated that giving additives
to birds reduces mortality and morbidity.
Feed Cost per Kilogram
of Broiler Produced
Table 5 presents the feed cost to produce a kilogram gain in weight. Statistical
analysis revealed no significant difference between the two treatment means. It is shown
that birds given Atovi incurred had a higher cost of feed compared to the birds given no
Atovi. However, the difference which Php 0.42 is still considered small to cause a
significant effect. The mean feed cost was P57.086.

Returns on Investment (ROI)
The returns on investment are presented in Table 6. The itemized expenditures are
presented in the appendix Table 8. Though the returns on investment was not subjected to
statistical analysis, the results revealed that birds given Atovi obtained higher returns on
investment (ROI) of 20.40 %. The birds given no Atovi, on the other hand had an ROI of
19.68 %. Higher returns were obtained from birds given Atovi because the birds had
higher final weights compared to birds given no Atovi.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to determine the effect of Atovi supplementation on the
growth performance of Cobb broilers. Eighty (80) day old broiler chicks were divided
into two treatments following the T-Test. Each treatment was replicated four times with
ten (10) birds per replication, making a total of forty (40) birds per treatment. The
treatments were T0-control/ pure water or no Atovi and T1-2.5g of Atovi per liter of
water.
This experiment was conducted at Benguet State University Poultry Experimental
Station, La Trinidad,Benguet from May to June 2011.
Statistical analysis revealed that there were no significant differences between the
two treatment means in terms of initial weight, gain in weight, feed conversion ratio and
feed cost to produce a unit gain in weight. This means that the birds in the two treatments
were more or less comparable to each other in the above parameters. The overall mean
initial weight of the birds was 0.453 kg, the overall mean gain in weight was 1.220 kg for
the birds given Atovi and 1.091 kg for the birds given no Atovi. The overall mean feed
conversion ratio was 1.754 and the overall mean feed cost was Php 57.086.
Significant differences were obtained in terms of final weight and the feed and
water consumptions. The birds given Atovi had heavier final weights with a mean of 1.67
kg and 1.546 kg for the birds given no Atovi. For the feed and water consumptions, the
birds given Atovi had a mean feed and water consumptions of 2.154 kg and 1.537 l
respectively. The birds given no Atovi on the other hand, had a mean feed and water
consumptions of 1.885 kg and 1.535 l, respectively.

15
Also, it is reflected in the results of the study that the Atovi was as efficient as the
vetracin as evidenced by the no incidence of mortalities nor morbidities in the birds given
Atovi in place of vetracin.
However, in terms of the returns on investment (ROI), birds given Atovi obtained
higher ROI of 20.40%, and birds given pure water or no Atovi supplementation had an
ROI of 19.68%.
Conclusion
Based on the result of the study, it is concluded that the addition of Atovi at the
level of 2.5 g/l of water given to the broilers results to heavier weights and also to take
the place of vetracin in preventing diseases and therefore higher return on investment.
Recommendation
Based on the result of the study the researcher recommends that Atovi can be
administered or can be added as water supplement at the level of 2.5 g/l of water for
broilers for better performance. However, it is also recommended that a further study be
conducted to include the effect of Atovi on the carcass quality.

ABSTRACT
The study was conducted at the BSU Experimental Station, La Trinidad, Benguet from May to June
2011 to determine the effect of Atovi supplementation on the growth performance of Cobb broilers.
A total of 80 day-old chicks were randomly distributed into two treatments and each
treatment was replicated four times with ten birds per replicate to make a total of 40 birds per
treatment. The two treatments were pure water or no Atovi supplementation and 2.5 g of Atovi per
liter of water. The Atovi supplementation was introduced to the birds at day 7 to 14 days but the
end of the study is at 40 days old.
Results showed that there were no significant differences in the initial weight, gain in
weight, feed conversion ratio and feed cost to produce a kilogram gain in weight. The average daily
gain in weight of the birds has a mean of 0.029 kg. It is revealed that the birds given 2.5 g 0f Atovi
per liter of water had the same performance as those of the control group in terms of final weight,
water and feed consumption. In terms of feed conversion ratio, it is revealed that birds given Atovi
and the control group had the same efficiency in converting feeds into flesh. The mean feed
conversion ratio of birds is 1.754
No incidence of mortality nor morbidity was incurred in all treatments which could possibly
mean that Atovi was efficient in improving the immune system of the birds that made them to have
a greater stamina to combat diseases caused by bacteria and viruses compared to the birds in the
control group given vetracin. In terms of the return on investment birds given Atovi had the higher
return.

The Effects of Atovi Supplementation on the Growth Performance
of Cobb Broilers /Resalie T. Mangawa. 2012
INTRODUCTION
Broiler production is one of the most developed animal industries. It is not only a
means of solving meat inadequacy, being an excellent source of protein, but it is also one
of the major sources of livelihood for some farmers because it generates profit in a short
period of time. Nowadays, most poultry raisers use feed additives to increase production
of poultry products. However, poultry raisers should choose a feed supplement or
additive containing better nutritive value suited to their animals which may be given in
small amount but functions greatly in the growth development of the animal body. One of
the newly introduced feed additives which, according to the manufacturer, improve the
performance of the livestock and poultry when added into their feed and/or water intake
is the Atovi and this is what the researcher would like to find out in this study i.e. the
effect of Atovi on the growth performance of broilers.
Atovi, according to the Vim-Vertex& Company, Inc. (2007), the manufacturer, is
a Filipino invented product based on molecular alteration, nuclear reaction and
nanotechnology. It is a feed premix powder made from vitamins and minerals.
The Vim-Vertex & Company, Inc. as cited in www.atovianimalg2.com(2007),
also claimed that the Atovi’s high micro potential energy charges the cells mitochondria
and immediately initiates the ATP pumps to run the Krebs cycle (cells whole mechanism)
that is all cells of all organs i.e. liver, kidneys, heart. Intestinal tract, muscles, bones,
etc.at all levels of the animal, making normal cells efficient while the deteriorating and
sickly cells revitalized, rejuvenated and restored ultimately making them efficient too.
Ones the body cells are efficient; they automatically regenerate and increase the immune
system and anti-bodies.

Also it was cited that Atovi corrects and maintains the digestive system properly.
Though this all nutritional and medication inputs are absorbed and utilized properly and
efficiently. Proof of this is the almost total absence of undigested proteins in the manure
and very low ammonia fumes which produce the foul odor ending up into a non-
pathogenic and organic fecal and further decomposition is not needed.
With metabolism performing properly, the genetic potentials and performance,
like that of the immune system are strengthened. The animals have greater stamina. They
do not easily contract disease caused by bacteria and viruses. In cases where medications
have to be administered such medicines are readily absorbed and utilized ensuring faster
recovery.
The result of the study will benefit both the researcher and the broiler raiser in
particular and also the broiler industry as a whole. If the result is found feasible, broiler
user may use Atovi as a feed supplement to improve the performance of the birds. The
result may also serve as reference materials for other students and researchers to come up
with follow-up researches.
The study was conducted at the BSU Experimental Station, La Trinidad, Benguet
using a total of 80 Cobb broiler subjected to 40 days of feeding period from May to June
2011. Generally, the study was conducted to determine the effect of Atovi
supplementation on the growth performance of broilers under upland condition.
Specifically, it aimed to determine the performance of broilers given Atovi in terms of
gain in weight, feed and water consumptions, feed conversion ratio, morbidity and
mortality rates, and net profit.

REVIEW OF LITERATURE
West (1977) defined feed additive as a substance added to compound ration or
protein concentrate in the course of manufacturing, for some specific functions such as,
stimulates growth and improves the efficiency of feed utilization.
Gillespie (1979) cited that feed additives are drug like materials added to basic
feed mix. Feed additives are not nutrients; they are added to feed mix to cause animals to
grow faster or to control some diseases. Similarly, Fronda (1972) mentioned that using
feed additive does not only make production of animals economical but also helps in the
control of diseases.
Card and Nesheim (1972) said that the addition of additives in poultry feeds will
often improve the rate of weight gain and feed efficiency of growing chicks and provide
the entire essential in adequate amount.
Lassiter and Edwards (1982) mentioned that additives are substances added to
feeds that are not included for their nutritional value but in one way or the other will
improve animal performance or efficiency of animal production.
Acker (1983) cited that wide acceptance of feed additives in poultry and swine
ration is attributed to their well-established benefit in improving growth rate, improving
feed conversion and reducing mortality and morbidity. He also stated that materials serve
as catalyst in digestion and metabolism in very small amount. Furthermore, he also
mentioned that the rearing of animals such as broilers in confinement increases the need
of vitamins in rations.
Atovi, according to the Vim-Vertex & Company, Inc. (2007) is made from
vitamins and minerals feed premix that improves the performance and efficiency of a cell

Atovi induces natural detoxification or expulsion of harmful compounds or
xenobiotics such as drugs, natural poisons and antibiotics on the cellular level. The
benefits attained in using Atovi feed premix are as follows:increaseoutput& productivity,
reduces feed intake, reduces redundant nutritional supplements and medication, reduces
consumption of water and power, eco-friendly manures and wastes because it does that
not emit foul odor and does not pollute the land, air & water. www.alibaba.com (2007).

MATERIALS AND METHOD
The materials and equipment used were: 80 day old broiler chicks (Cobb),
weighing scale, measuring cups, spoon, stick brooms, disinfectant, incandescent bulbs,
old newspaper sheets, brooding and rearing cages, record book, feeding and drinking
troughs, Atovi and commercial feeds (purina).
All the brooding and rearing cages were thoroughly cleaned with laundry soaps
and disinfected a week before the arrival of the chicks. Newspaper sheets were placed on
the floor to minimize the escape of heat inside the brooder and to serve as mattings. Also,
it served as receptacle for feeds for the first few days. In addition, waterers were well
secured on the floor to minimize spillage and these were covered with wire screen to
prevent the birds from stepping inside the waterer. Furthermore, the brooders were heated
two hours before the arrival of the chicks.
Upon arrival, the 80 birds were divided into two treatments following the T-Test.
Each treatment had four replications with 10 birds per replicate, making a total of 40
birds per treatment group. The two treatments were:
T0= pure water/ no Atovi
T1= 2.5g Atovi per liter of water
All birds were subjected to the same management except on the drinking water
offered to them. Birds in the control group (T0) were given pure water withvetracin for
the first two weeks but with no supplementation of Atovi. Birds in treatment (T1) were
given Atovi supplementation at the level of 2.5 g per liter of water but without vetracin
for the first two weeks. The Atovi supplementation was introduced to the birds at day 7
until they were 40 days old.

Feeding was done 4 times a day, at 6 and 10 o’clock in the morning and 2 and 6
o’clock in the afternoon. During the first two weeks of brooding, the chicks were fed with
chick booster containing 24% of crude protein. This was followed by broiler starter mash
for the next two weeks (15th-30th) containing 21% crude protein, and then finisher ration
containing 18% crude protein on the remaining weeks until the end of the study or at 40
days old.
Birds in all treatment were also subjected to the same lighting management.
Brooding cages were lighted day and night. However, lights were turned off for a period
of one hour daily at 5-6:00 pm for the birds to be accustomed to the dark surrounding in
case of brown outs. But during the conduct of the study, there were no brown outs
incurred.
To help maintain the good health of the birds, hygiene and sanitation were
maintained to avoid the occurrence of diseases. Manures of the birds were scrapped daily.
Also, the birds were vaccinated against avian pest on the 10th day of brooding.

RESULTS AND DISCUSSION
Body Weights
Table 1 presents the mean initial and final weights of the birds in the two
treatments. Statistical analysis revealed that the initial weights of the birds in the two
treatments were not significantly different. This implies that the birds were more or less
of the same weight at the start of the study. The birds had an overall mean initial weight
of 0.453 kg.
In terms of final weight, statistical analysis revealed a highly significant
difference between treatment means. The mean final weight of birds given Atovi were
heavier with a mean of 1.67 kg compared to the mean final weight of birds given pure
water or no Atovi supplementation which was 1.546 kg.
Total Gain in Weight
The total gains in weight of the birds in the two treatments are presented in Table
2. Statistical analysis revealed that the gains in weight of the birds in the two treatments
were not significantly different.Thebirds given Atovi had a mean gain in wieght of 1.220
kg and the birds given pure water or no Atovi supplementation had a mean of 1.091 kg.
This implies that adding Atovi into the water of birds did not stimulate the growth of the
birds. This finding is different from the claim of the

manufacturer, the Vim-Vertex & Company, Inc., that Atovi premix, when given to the
birds, improves their growth rate.
Feed and Water Consumption
The mean feed and water consumptions of the birds in the two treatments are
presented in Table 3. True to both feed and water consumptions, significant differences
were observed between the two treatments. Birds given Atovi supplementation consumed
more feeds and water with means of 2.154 kg and 1.537 l, respectively. On the other
hand, the birds in the control group or those not given Atovi supplementation had a mean
feed consumption of 1.1885 kg and a mean water consumption of 1.535 l. The result
implies that giving Atovi to the birds increases their feed and water consumptions.
Perhaps the Atovi had made the feed and water palatable, hence, the increase on their
consumptions.

Feed Conversion Ratio (FCR)
The mean feed conversion ratios of the birds in the two treatments are presented
in Table 4. Statistical analysis revealed that there was no significant difference between
the two treatment means indicating that giving Atovi to the birds did not affect their feed
conversion ratio. The overall mean feed conversion ratio obtained was 1.754.
Morbidity and Mortality
There was no incidence of mortality or morbidity among the birds from the start
up to the end of the study. Even if the treated birds were just given Atovi and were not
given commercial vetracin as done to the control birds, these were able to maintain good
health despite the fluctuation of the environmental temperature that could have made the
birds prone to respiratory diseases during the conduct of the study. These could possibly
mean that Atovi given to the treated bird was efficient in enhancing the immune system
of the birds or it had made them to have a greater stamina to combat diseases caused by
bacteria and viruses. The result agrees with Acker (1983) who stated that giving additives
to birds reduces mortality and morbidity.
Feed Cost per Kilogram
of Broiler Produced
Table 5 presents the feed cost to produce a kilogram gain in weight. Statistical
analysis revealed no significant difference between the two treatment means. It is shown
that birds given Atovi incurred had a higher cost of feed compared to the birds given no
Atovi. However, the difference which Php 0.42 is still considered small to cause a
significant effect. The mean feed cost was P57.086.

Returns on Investment (ROI)
The returns on investment are presented in Table 6. The itemized expenditures are
presented in the appendix Table 8. Though the returns on investment was not subjected to
statistical analysis, the results revealed that birds given Atovi obtained higher returns on
investment (ROI) of 20.40 %. The birds given no Atovi, on the other hand had an ROI of
19.68 %. Higher returns were obtained from birds given Atovi because the birds had
higher final weights compared to birds given no Atovi.

SUMMARY, CONCLUSION AND RECOMMENDATION
Summary
The study was conducted to determine the effect of Atovi supplementation on the
growth performance of Cobb broilers. Eighty (80) day old broiler chicks were divided
into two treatments following the T-Test. Each treatment was replicated four times with
ten (10) birds per replication, making a total of forty (40) birds per treatment. The
treatments were T0-control/ pure water or no Atovi and T1-2.5g of Atovi per liter of
water.
This experiment was conducted at Benguet State University Poultry Experimental
Station, La Trinidad,Benguet from May to June 2011.
Statistical analysis revealed that there were no significant differences between the
two treatment means in terms of initial weight, gain in weight, feed conversion ratio and
feed cost to produce a unit gain in weight. This means that the birds in the two treatments
were more or less comparable to each other in the above parameters. The overall mean
initial weight of the birds was 0.453 kg, the overall mean gain in weight was 1.220 kg for
the birds given Atovi and 1.091 kg for the birds given no Atovi. The overall mean feed
conversion ratio was 1.754 and the overall mean feed cost was Php 57.086.
Significant differences were obtained in terms of final weight and the feed and
water consumptions. The birds given Atovi had heavier final weights with a mean of 1.67
kg and 1.546 kg for the birds given no Atovi. For the feed and water consumptions, the
birds given Atovi had a mean feed and water consumptions of 2.154 kg and 1.537 l
respectively. The birds given no Atovi on the other hand, had a mean feed and water
consumptions of 1.885 kg and 1.535 l, respectively.

15
Also, it is reflected in the results of the study that the Atovi was as efficient as the
vetracin as evidenced by the no incidence of mortalities nor morbidities in the birds given
Atovi in place of vetracin.
However, in terms of the returns on investment (ROI), birds given Atovi obtained
higher ROI of 20.40%, and birds given pure water or no Atovi supplementation had an
ROI of 19.68%.
Conclusion
Based on the result of the study, it is concluded that the addition of Atovi at the
level of 2.5 g/l of water given to the broilers results to heavier weights and also to take
the place of vetracin in preventing diseases and therefore higher return on investment.
Recommendation
Based on the result of the study the researcher recommends that Atovi can be
administered or can be added as water supplement at the level of 2.5 g/l of water for
broilers for better performance. However, it is also recommended that a further study be
conducted to include the effect of Atovi on the carcass quality.
