复合益生菌制剂对肉鸡生长性能、屠宰性能和免疫指标的影响
Effects of Compound Probiotics on Growth Performance, Slaughter Performance and Immune Indices of Broilers
摘要
Abstract
This experiment was conducted to determine the effects of different proportions of compound probi-otics on growth performance, slaughter performance and immune indices of arbor acres(AA)broilers. Three hundred and twenty 1-day-old healthy male AA broilers were randomly divided into 4 groups with 4 replicates per group and 20 broilers per replicate. The broilers in control group(groupⅠ)were fed a basal diet,and the others in groupsⅡ,ⅢandⅣwere fed the basal diets supplemented with 1 000 mg/kg different proportions of compound probiotics. The experiment lasted for 42 days. The results showed as follows:1)at 1 to 42 days of age, the average daily feed intake and average daily gain of broilers in groupⅢwere the highest,and the ratio of feed to gain was the lowest, which were significantly different compared with group Ⅰ(P<0.05). 2)The breast muscle percentage in groups Ⅲ and Ⅳ was significantly higher than that in group Ⅰ(P<0.05). 3)At 21 and 42 days of age, the serum immunoglobulin A content of broilers in group Ⅲ was significantly higher than that in group Ⅰ(P<0.05). Therefore, dietary compound probiotics can increase the growth perform-ance, slaughter performance and serum immunoglobulin content to different degrees, and supplemented with 1 000 mg/kg proportions of 1:2:1:1(Bacillus subtilis:Saccharomyces cerevisiae:Lactobacillus acidophilus:Bifidobacterium lactis)compound probiotics can reach the best effects.关键词
