发酵椰蓉渣饲料对文昌鸡育肥期生长性能和屠宰性能的影响

Effect of fermented coconut residue feed on growth performance and slaughter performance of Wenchang chickens during finishing period

试验旨在探究发酵椰蓉渣饲料对文昌鸡生长性能和屠宰性能的影响。试验选用10 200只50日龄初重(680±25) g的文昌鸡,随机分为2组,每组34个重复,每个重复150只鸡。对照组文昌鸡饲喂基础日粮,试验组在基础日粮中添加发酵椰蓉渣。试验期60 d。结果显示,与对照组相比,试验组文昌鸡末重及平均日增重均显著提高(P<0.05),料重比显著降低(P<0.05),死淘率有下降趋势(P>0.05);与对照组相比,试验组文昌鸡的屠宰性能无显著差异(P>0.05)。研究表明,发酵椰蓉渣饲料能够提高文昌鸡生长性能。

The purpose of the experiment was to explore the effect of fermented coconut residue feed on the growth performance and slaughter performance of Wenchang chickens.A total of 10200 fifty-day-old Wenchang chickens with initial weight of(680±25)g were randomly divided into two groups,with 34 replicates per group and 150 chickens per replicate.The Wenchang chickens in control group were fed a basal diet,and Wenchang chickens in experimental group were fed a basal diet supplemented with fermented coconut residue.The experimental period was 60 days.The results showed that compared with the control group,the final weight and average daily gain of the experimental group were significantly increased(P<0.05),while the feed to gain ratio was significantly reduced(P<0.05).The mortality rate of the experimental group showed a decreasing trend(P>0.05).Compared with the control group,there was no significant difference in slaughter performance of Wenchang chickens in the experimental group(P>0.05).The study indicates that adding fermented coconut residue feed can improve the growth performance of Wenchang chickens.
