The Effects of Glutamine Used as Substitute for Antibiotics Feed Additive on Production Performance and Slaughter Characteristics of the Yellow Chicken
摘要
Abstract
[Objective] An experiment was conducted to study the effects of glutamine replacing antibiotics in diet on production performance, slaughter characteristics of the yellow chicken. [ Method ] One hundred - eighty - one - day - old yellow chicken were randomized into two control groups and three trial groups with 3 replicates per group and 12 chickens per replicate. The positive control group was fed with diet supplemented with antibiotics (0.03% Nosiheptide + 0.025% Colistin sulfate premix). The negative control group was fed with basal diet. Birds in the trial group I, Ⅱ and Ⅲ were fed with diet supplemented with 1,2, 3 g/kg glutamine, respectively. [Result] The average weight (kg) of 81 -day -old chicken in each group were 2.72, 2.66, 2.62,2.84, 2.68 kg, and there was no significant difference(P > 0.05) among the groups, and the average weight of the trial group II was higher than the positive control group by a margin of 4.41%. The feed conversion ratios of the whole period were not significantly different from those with 2. 67, 2.66, 2.80, 2.64 and 2.62 respectively (P > 0.05). The results showed that there were no significant differences (P > 0.05) among the birds fed with diets supplemented with glutamine of 0.1% , 0.2% , 0.3% substituting feed antibiotic additive compared with birds in control groups in terms of the body weight, feed conversion, other indicators of carcass quality of the 81 d chicken. [ Conclusion]The evaluation of 81 d finish body weight, feed intake to body weight ratio and death rate of the chicken showed that using substituted antibiotic feed additive with 0.2% glutamine is suitable in the diet of yellow chicken .关键词
