中草药饲料添加剂对肉羊生产性能和粪污排放的影响
|
摘要
试验旨在研究中草药饲料添加剂对肉羊生产性能和粪污排放的影响,以期为中草药饲料添加剂在肉羊生产中的应用提供理论依据。选择40只体况良好、体重相近的萨寒杂交肉羊为研究对象,随机分成4个处理组,其中A组为对照组,饲喂基础日粮,B组、C组和D组3个试验组分别添加0.4%、0.8%、1.2%的中草药饲料添加剂。结果表明:C组羊的采食量和日增重水平最高,分别较对照组提高18.93%和45.00%,料肉比较对照组降低18.03%;C组粪污排放量和单位增重粪污排放量分别较对照组降低7.01%和29.92%。说明在该试验条件下,肉羊基础日粮中添加中草药饲料添加剂能够显著提高采食量和平均日增重,降低料肉比,其中在日粮中的最适添加比例为0.8%。
This experiment was to study the effects of Chinese herbal feed additive on production performance and feces discharge of mutton sheep so as to provide a theoretical foundation for the application of Chinese herbal feed additives in mutton production. 40 crossbred mutton sheep with good body condition and similar weight that was offspring crossed by Suffolk sheep and Small-tail han sheep were randomly divided into 4 treatment groups. Group A was a control group,and other 3 groups were experimental group,the same basal diet were fed,but with different amount of Chinese herbal feed additives they were 0,0.4%,0.8% and 1.2% in group A,group B,group C and group D respectively. The results showed that the intake and daily gain in group C increased by 18.93% and45% over the control group respectively,while the feed conversion ratio of the control group was 18.03% more than that of group C.Feces discharge in group C was 7.01% lower than that in the control group,in addition,feces discharge to unit gain in group C was29.92% lower than that in the control group. It was concluded that the Chinese herb feed additives could significantly increase feed intake and average daily gain of mutton sheep,and improve feed conversion ratio. Under this experiment,the best addition rate of Chinese herb feed additives is 0.8% in ration.
