Abstract: The present investigation entitled “the growth performance, haemato-biochemical and carcass quality of broiler chickens supplemented with vitamin E, Zn, and Cr” was conducted at the Poultry Research and Training Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Modipuram, Meerut (Uttar Pradesh) for a total of 6 week, to study the effects of different inclusion levels of supplementary Vitamin E, Zn and Cr either individually or in combination on the growth performance, hemato-biochemical characteristics and carcass quality of broiler chickens. 240 day old chicks of Cobb 400 breed were used in this experiment. The chicks were divided into 8 groups of 30 chicks each, with 3 replicates of 10 chicks in each group. The chicks were wing banded, weighed and then randomly distributed in dietary treatment into eight groups consisting of 30 chicks in each group. The chicks were reared under deep litter production system of management. These chicks were provided with broilers starter and finisher feeds formulated to provide 22% CP and 20% CP respectively. T1, fed mixed ration only, served as control. T2 was fed mixed ration supplemented with 250 mg/kg vit. E, T3 was fed mixed ration supplemented with 50 mg/kg Zn, T4 was fed mixed ration supplemented with 0.7 mg/kg Cr., T5 was feed mixed ration supplemented with 250 mg/kg vit. E + 50 mg/kg Zn. , T6 was fed mixed ration supplemented with 250 mg/kg vit. E + 0.7 mg/kg Cr. , T7 was fed mixed ration supplemented with 50 mg/kg Zn. + 0.7 mg/kg Cr. , T8 was fed mixed ration supplemented with 250 mg/kg vit. E + 50 mg/kg Zn. +0.7 mg/kg Cr. Growth performance, carcass quality and hemato-biochemical parameters were investigated. The average body weight of six week of broiler chicks were 1576.58 ± 2.45, 1701.90 ± 2.45, 1673.80 ± 2.45, 1631.63 ± 2.45, 1799.50 ± 2.45, 1770.00 ± 2.45, 1738.90 ± 2.45 and 1862.40 ± 2.45 gm in group T1, T2, T3, T4, T5, T6 , T7, and T8 respectively. The 6th week body weight differences among the treatment groups were statistically significant (p<0.05).The average total feed consumption from 1-6 weeks were 3500.01 ± 1.16, 3522.93 ± 1.73, 3514.98 ± 2.31, 3508.00 ± 3.46, 3545.02 ± 3.46, 3540.00 ± 2.89, 3529.97 ± 3.46 and 3549.96 ± 4.04 gm for the group T1, T2, T3, T4, T5, T6 , T7, and T8 respectively. The total feed consumption from1-6 weeks among the treatment groups were statistically significant (p<0.05). The average total feed conversion ratio for the period 1-6 week were 2.29 ± 0.005, 2.11 ± 0.003, 2.14 ± 0.003, 2.22 ± 0.005,2.03 ± 0.005, 2.06 ± 0.005, 2.09 ± 0.005 and 1.96 ± 0.005 for group T1, T2, T3, T4, T5, T6 , T7, and T8 respectively The average total cholesterol in mg per dl were 183.07±0.44, 162.00±0.44, 166.33±0.50, 171.33±0.59, 141.00±0.54, 148.00±0.69, 150.33±0.45 and 135.33±0.63 for T1, T2, T3, T4, T5, T6 , T7, and T8 respectively. The average dressed carcass percent for the different treatment groups were 69.40±0.42, 71.06±0.57, 70.40±0.34, 69.80±0.23, 72.90±0.21, 72.50±0.15, 71.80±0.31and 73.50±0.10 for T1, T2, T3, T4, T5, T6 , T7, and T8 respectively. The average thigh weight percent for the different treatment groups 30.50 ± 0.08, 32.40 ± 0.05, 31.90 ± 0.03, 31.30 ± 0.06, 33.30 ± 0.03, 33.10 ± 0.05, 32.80 ± 0.08, 33.80 ± 0.06 for T1, T2, T3, T4, T5, T6, T7 and T8 respectively. Weekly feed consumption, weekly body weight and weekly body weight gain were significantly higher in supplemented treatment groups with combined elements than individual elements and lowest in control group. Dressing %, Eviscerated Weight % , Thigh weight % , Liver wt %, Heart wt%, Spleen wt %, Gizzard wt % were higher in supplemented groups and lowest in control group. The highest % of carcass characteristics was observed in T8. Hemato-biochemical characteristics were significantly higher in supplemented groups than control except for cholesterol which was higher in control groups as compared to supplemented groups. Total and weekly feed consumption was not significantly differ in 0-3 weeks’ period but showed a significant difference among treatment groups from 4-6 weeks of the experiment. T8 showed a preferentially high total and weekly feed consumption. The present investigation showed an improvement in growth performance, hemato-biochemical parameters and carcass characteristics among treatment groups supplemented with vitamin E, zinc, chromium either individually or in combination as compared to control groups. The effects were higher when the elements supplemented were combined due to their synergistic effects. It is therefore concluded that supplementation of combined vitamin E, chromium and zinc has a preferential effect on growth performance, hemato-biochemical parameters and carcass characteristics of broiler chickens as compared to supplementing individual elements or control in broiler production.
