育雏期添加复方中草药对肉鸡生长性能的影响

摘要

选用1日龄的白羽肉鸡1200只，随机平均分为12组，分别在1~10日龄、1~15日龄和1~19日龄的阶段饲料中添加饲料质量1.5%的复方中草药，以常规饲料饲喂为对照，每组1个处理，3次重复，其他管理同常规，研究了育雏期添加不同时长的复方中草药对肉鸡生产性能指标的影响。结果表明：育雏期在饲料中添加不同时长的复方中草药均能够提高肉鸡采食量、平均体重均匀度和出栏平均体重，降低料肉比和死亡率，其中，添加时长为1~15日龄和1~19日龄时效果较好，但二者所有指标差异均不显著。考虑到中草药的使用成本，认为在肉鸡育雏期的1~15日龄阶段饲料中添加1.5豫的复方中草药较为经济。%The effect of compound traditional Chinese medicine on growth performance in brooding stage of broilers was reasearched. 1 200 one-day-old broilers were randomly divided into 12 groups,test group were fed with basal diets added with 1.5% traditional Chinese medicine from 1 to 10,1 to 15 and 1 to 19 days old, each group had 1 treatment and 2 repeats. Control group was fed basal diets. The results showed that compound traditional Chinese medicine feed additive can feed increase intake, weigh unifor-mity and maketing weight,reduce feed to gain ratio and death ratio. Effect was better when the additive was fed from 1 to 15 days old and from 1 to 19 days lod. then the other groups, but the date wasn’s remarkable between these two groups.Considering the cost of compound traditional Chinese medicine, the economic benefit was higher when this additive was fed from in a ratio of 1.5% from 1 to 15 days old.
