摘  要：
【目的】研究基础日粮中添加丁酸钠替代饲用抗生素对白羽肉鸡生产性能及免疫器官指数的影响。【方法】将225只1日龄的白羽肉鸡随机分为5个处理组(每个处理组3个重复,每个重复15只)。分组情况:阳性对照组在基础日粮中添加0.03%那西肽+0.025%硫酸粘杆菌素预混剂的抗生素;阴性对照组饲喂基础日粮;试验Ⅰ组在基础日粮中添加0.25%丁酸钠;试验Ⅱ组在基础日粮中添加0.5%丁酸钠;试验Ⅲ组在基础日粮中添加0.75%丁酸钠。【结果】42 d的各组平均体重分别为2.32、2.43、2.20、2.30、2.31 kg,差异不显著(P>0.05)。1~42 d料重比分别为1.67、1.62、1.69、1.67、1.64,均差异不显著(P>0.05)。14和21 d各试验组免疫器官指数与阳性对照组均无显著差异(P>0.05)。【结论】从白羽肉鸡42 d生产性能和免疫器官指数等指标综合来看,用添加0.5%丁酸钠替代白羽肉鸡饲用抗生素是可行的。

摘  要：
【Objective】 An experiment was conducted to study the effects of sodium butyrate replacing antibiotics in diet on production performance and immune organ index of white broilers.【Method】234 one-day- old AA broilers were randomized into two control groups and four trial groups with 3 replicates per group and 13 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.Broilers in the trial group Ⅰ,Ⅱ and Ⅲ were fed with diet supplemented with 0.25%,0.5%,and 0.75%Sodium butyrate.【Result】The average weight of 42-day-old chicken in each group were 2.32 kg,2.43 kg,2.20 kg,2.30 kg,2.31 kg respectively,and there was no significant difference(P >0.05).The feed /gain ratio of the whole period were 1.67,1.62,1.69,1.67 and 1.64 respectively,and there were no significant difference(P >0.05) among other groups.Compared with that of the positive control group,there was no significant difference(P >0.05) on immune organ indexes of white broilers in each group.【Conclusion】 It showed that using substituted antibiotic feed additive of 0.5%sodium butyrate is suitable in the diet of white broilers from the evaluation of 42 d production performance and immune organ index of the broilers.
