摘要
本试验选用 0日龄樱桃谷肉鸭 6 0 0只 ,随机分为 1 0个组 (9个试验组 +1个对照组 ) ,每组 2个重复 ,每个重复 5 0只肉仔鸭。试验组采用二因素、每个因素三个水平的完全随机设计 ,以研究抗生素 (0～ 7日龄添加 )和益生素 (8～ 35日龄添加 )组合使用对 0～ 35日龄肉鸭生产性能的最佳水平组合。综合生产性能的分析结果表明 :土霉素用 0 1 % ,益生素用 0 0 75 %组合使用饲喂肉鸭的效果最佳。鉴于土霉素已逐渐淘汰 。
The trial was mede to study the best conbinative level of antibiotic(feeding from o day to to 7 days)and probiotic(feeding 8 days to 35 days)on the performance of meat ducks from o day to 35 days.600 cherry-vally meat ducks(0-day-old) were divide into 10 groups(9 experment groups and 1 control group)randomly,with 2 subgroups in each.There were 50 meat ducks in each subgroup.The experiment groups were designed on two factors and three levels in each factor.The results showed that meat ducks gained best performance while level of antibiotic was 0.1 percent,and level of probiotic was 0.075 percent.
