抗生素与益生素组合效果研究

本试验选用1日龄樱桃谷肉鸭600只,随机分为10个组(9个试验组+1个对照组),每组2个重复,每个重复30只肉仔鸭。试验组采用二因素,每个因素3个水平的完全随机设计,以研究抗生素(1～7日龄添加)和益生素(8～42日龄添加)组合使用对1～42日龄肉鸭生产性能的最佳水平组合。结果表明:土霉素用0.1%,益生素0.075%组合使用饲喂肉鸭的效果最佳。

Combinative Eeffect of Antibiotic and Probiotic on Feeding Meat Ducks

The trial was made to study the best combinative level of antibiotic(feeding from1day to7days)and probiotic(feeding8days to42days)on the performance of meat ducks from1day to35days.600cherry-Vally meat ducks(0-day-old)were divide into10groups(9experiment groups and1control group)randomly,with2subgroups in each.There were50meat ducks in each subgroup.The experiment groups were t0meat 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 was0^1percent ,and level of probiotic was0.075perecent.
