Effect of Feeding Pro Biotic on Growth and Production Performance in Broiler Chicks

Abstract

The present study was conducted on the data collected from the experimental growth performance and conformation traits of Cobb 400 strain of broiler work was carried out under Integrated Farming System Research Project at Sardar Vallabhbhai Patel University of Agriculture & Technology Modipuram, Meerut. 120 birds Cobb 400 of synthetic strain were selected randomly and used for the study purpuse (DOC) and divided into four equal groups, each were fed different diets. Feed consumption, Body weight gain, feed conversion ratio (FCR) and shank length, keel bone, hock circumference were measured. Average feed consumption of broiler chicks during 0-1 week of age for the group fed diet T1. T2, T3 and T4 was found 145.0 ± 0.577, 136.6 ± 1.552, 138.7 ± 1.302 and 145.9 ± 1.320 gm, respectively. The overall average feed consumption for T1, T2, T3 and T4 was 141.55 ± 1.187 gm. Average feed consumption of broiler chicks up to 6 week of age for the group fed diet T 1, Ti, T3 and T4 was found 3373.4 ± 1.246, 3322.4 ± 0.887, 3370.9 ± 1.123 and 3402.4 ± 0.679 gm, respectively. The overall average feed consumption for T1, T2, T3 and T4 was 3367.4 ± 12.382 gm, up to six week of age. Significant differences (P<0.05) exist in feed consumption of broiler chicks among different treatment of diet fed to broiler chickens during different diet. Average body weight gain of broiler chicks during 5-6 week ofage for the group T1, T2, T3 & T4 was found 445.0 ± 1.036, 451.0 ± 0.823, 469.0 ± 0.540 and 481.8 ± 0.881 gm respectively. The overall average weight gain for T1, T2, T3, and T4 was 461.70 ± 0.820 gm, during six week of age. Average body weight gain of broiler chicks up to 6 week of age for the group T1, T2, T3 & T4 was found 2149.1 ± 1.683, 2224.9 ± 2.999, 2331.7 ± 0.649 and 2499.3 ± 1.649 gm respectively. The overall average weight gain for T1, T2, T3, and T4 was 2301.25 ± 1.817 gm, up to six week of age. Significant differences (P<0.05) exist in body weight gain of broiler chicks among different treatment of diet fed to broiler chicks. Average feed conversion ratio of diet T 1, T 2, T 3 & T 4 was found 1.57 ± 0.034, 1.49 ± 0.096, 1.44 ± 0.0 I 0 and 1.36 ± 0.042. The overall average feed conversion ratio for T1, T2. T3, and T4 was 1.47 ± 0.045, up to six week of age. At the age of 6 week average shank length, keel bone length and hock circumference of broiler fed diet T1, T2, T3 and T4was found 70.60 ± 0.704, 73.10 ± 0.727, 79.20 ± 0.728 and 81.90 ± 0.641 mm; 94.70 ± 0.639, 98.50 ± 0.468, 102.60 ± 0.676 and 104.20 ± 0.462; 72.70 ± 0.571, 76.00 ± 1.040, 82.40 ± 0.787 and 84.40 ± 0.653 mm , respectively. The overall averages and length, keel bone length and hock circumference was 76.20 ± 0.700, 100.00 ± 0.561 and78.87 ± 0.762 mm, respectively.
