Abstract
One
hundred and eighty (180) unsexed day-old, commercial broiler
chicks were purchased from Venkateshwara Hatcheries Pvt. Ltd.
These chicks were weighed individually and uniformly distributed
as 30 chicks in each of six groups. Each group was divided into
two replicates with 15 chicks in each. The birds were offered
feed and water ad-libitum. The chicks were fed with
starter mash which contained crude protein 22% and metabolizable
energy 2918 Kcal / kg up to three weeks of age. For next 3 weeks
ie. from 4 to 6 weeks of age with finisher mash which contained
crude protein 20% and metabolizable energy 2966 Kcal/ kg. Group
T0 (control group) was fed standard broiler mash. In group T1
Vitamin A was added @ 8500 IU/ litre of Drinking water. Group T2
was fed Broiler mash + Vitamin C @ 500 mg/ kg of feed. Group T3
was fed Broiler mash + Vitamin E @ 300 mg/ kg of feed. Group T4
was given Broiler mash + Levamisole @ 2 gm/ kg of feed and
group. T5 was provided with the combination of all the feed
supplements Vitamin A added @ 8500 IU/ litre of Drinking water,
Broiler mash + Vitamin C @ 500 mg/ kg of feed + Vitamin E @ 300
mg/ kg of feed + Levamisole @ 2 gm /kg of feed. The results of
economics of broiler production showed that net cost of
production per bird was maximum for T5 (Rs. 76.78) followed by
T4 (Rs. 67.34), T1 (Rs. 66.56), T0 (Rs. 59.11), T2 (Rs. 58.16)
and T3 (Rs. 58.02). The net profit per bird for groups T0, T1,
T2, T3, T4 and T5 was Rs. 28.44, 21.49, 30.59, 30.48, 20.41and
11.12, respectively. The supplemented groups T2 and T3 have more
net profit than control group. However, group T1, T4 and T5 had
less net profit than the control group.
