Effect of Dietary Supplementation of Garlic (Allium Sativum) Powder on Growth Performance and Blood Biochemical Parameters in Broilers

Abstract

Thesis Title: Effect of dietary supplernentation of garlic (Allium sativum) powder on growth perfonnance and blood biochemical parameters in broilers. The present investigation entitled "the growth perfonnance, haemato-biochemical and carcass quality of broiler chickens supplemented with garlic (Allium sativum) 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 garlic powder (Allium sativum) on the growth performance, hemato-biochemical characteristics and carcass quality of broiler chickens. 480 day old chicks (DOC) of Cobb 400 breed were used in this experiment. The chicks were divided into 4 groups of I 20 chicks each, with 4 replicates of 30 chicks in each group. The chicks were wing banded, weighed and then randomly distributed in dietary treatment into four groups consisting of 120 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 20o/o CP respectively. Tl, fed mixed ration only, served as control. T2 was fed mixed ration supplemented with 250 gram/1 OOkg ration, T3 was fed mixed ration supplemented with 500 gram/ I OOkg ration, T4 was fed mixed ration supplemented with 750 gram/ I OOkg ration. Growth performance, carcass quality and hemato-biochemical parameters were investigated. The average • body weight of six week of broiler chicks were 1704.138 ± 5.979, 1747.343 ± 5.633, 1781.130 ± 6.162 and 1817.358 ± 7.181 gm in group Th T2, T3, and T4 respectively. The 6th week body weight differences among the treatment groups were differed significantly (p<0.05).The average total feed consutnption from 1-6 weeks were 3508.353 ± 7.632, 3527.720 ± 2.621, 354 7.270 ± 3.538 and 3536.283 ± 3.835 gm for the group T1._ T2, T3, and T4 respectively. The total feed consumption from 1-6 weeks among the treatment groups were differed significantly (p<0.05). The average total feed conversion ratio for the period 1-6 week were 2.108 ± 0.005., 2.065 ± 0.006'1 2.038 ± 0.007 and 2.007 ± 0.008 for group T1, T2'1 T3, and T4 respectively The average total cholesterol in mg per dl were 184.205 ± 1. 901, 171.333 ± 1.316, 160.775 ± 1.504 and 145.120 ± 3.027 for T1, T2, T3, and T4 respectively. The average dressed carcass percent for the different treatment groups were 63.064 ± 0.273, 67.796 ± 0.288, 68.994 ± 0.071 and 71.225 ± 0.17 I for T" T2, T3, and T4 respectively. The average thigh \veight percent for the different treatn1ent groups 28.171 ± 0.035, 28.285 ± 0.028, 28.812 ± 0.029 and 30.030 ± 0.025· for T" T2 T3._ and T4 respectively. Weekly feed consumption, weekly body \\·eight and \Veekly body \Veight gain \Vere significantly higher in supplernented treatrnent groups \vith combined elernents than individual elements and lowest in control group. Dressing%, Eviscerated Weight <7o Thigh \veight % , Liver wt o/o, Heart wt%, Spleen wt %, Gizzard wt % were higher in supplen1ented groups and lo\vcst in control group. The highest % of carcass characteristics \vas observed in T4. Hernato-biochen1ical characteristics were significantly higher in supplen1ented groups than control except for cholesterol which was higher in control groups as con1parcd to supplcrnented groups. rotal and \\et!kly feed consutnption differed significantly. T4 showed a preferentially high total and \Vech.ly feed consumption.
