日粮添加黑水虻虫粉对肉鸭生长性能、羽毛生长和屠宰性能的影响

试验旨在研究日粮中添加黑水虻虫粉对肉鸭生长性能、羽毛生长和屠宰性能的影响。试验选取900只21日龄体重相近的公番鸭,分为3个组,每组5个重复,每个重复60只番鸭。对照组为基础日粮,试验组分别在基础日粮中添加3%和5%黑水虻虫粉。结果显示:①日粮黑水虻虫粉对肉鸭各阶段体重、平均日采食量、平均日增重和料重比无显著影响(P>0.05);②日粮添加黑水虻虫粉对肉鸭45、55、65和75日龄主翼羽长度和宽度无显著影响(P>0.05),但有提高65日龄第3主翼羽宽度的趋势(P>0.05);③日粮添加黑水虻虫粉对肉鸭屠宰性能和器官指数无显著影响(P>0.05);但从数值上看,5%黑水虻虫粉降低胸肌率,降幅为5.88%(P>0.05)。综上,日粮添加3%和5%黑水虻虫粉对肉鸭生长性能、羽毛生长、屠宰性能和器官指数无显著影响,具备应用的可行性。

Effects of Dietary Hermetia illucens Larvae Meal on Growth Performance,Feather Growth and Slaughter Performance in Muscovy Ducks

This experiment was conducted to evaluate the effects of dietary Hermetia illucens larvae(HI)meal on growth performance,feather growth and slaughter performance in Muscovy ducks.A total of 90021-day-age male Muscovy ducks were selected and randomly divided into 3 groups with 5 replicates per group and 60 ducks per replicate.The control group was fed on a basal diet(HI0)and the two test groups were fed on the basal diet with an additive of 3%or 5%HI meal(HI3 and HI5).The results showed that:①Dietary HI meal had no significant effect on BW,ADFI,ADG and FCR in ducks(P>0.05).②There was no difference in the width and length of primary feathers among 3 groups on Day 45,5565 and 75(P>0.05),while the width of the third primary feather on Day 65 in the HI5 group was higher than that of the HI0 group(P>0.05).③Dietary HI meal had no significant effect on slaughter performance and organ index(P>0.05),while the breast rate of the HI5 group was lower than that of the HI0 group(P>0.05).In conclusion,dietary 3%and 5%HI meal had no significant effect on growth performance,feather growth and slaughter performance.
