DDGS对麻黄肉鸡生长性能的影响

试验选取32日龄的麻黄肉鸡1200只,随机分成4组,每组5个重复,每个重复60只鸡。饲粮分别添加0%,2%,4%,6%的DDGS,试验期为36 d。试验结果表明,日粮中添加0%、4%、6%、8%的DDGS对黄羽肉鸡的生长性能均无显著影响(P>0.05)。但4%添加组料肉比最低。综合考虑饲料成本及经济效益等因素,本试验条件下,以DDGS添加量为4%的效益最好。

Effects of DDGS on growth performance in Ephedrine broilers

A tolal of 1200,21-day-old broilers were randomly divided into 4 treatments with 5 replicates of 60 chickens per replicate.4 experimental diets were added with 0 %,4 %,6 %,8 % DDGS,respectively.The experiment period was 36 d.The results showed that: 0 %,4 %,6 %,8 % DDGS adding levels had no significant effect on the growth performance(P > 0.05).But,the feed conversion ration of 4 % adding group was the lowest Take the cost of forage and economic efficency into consideration,the optimum adding level was 0.60 %,which could get the best interests.
