摘要
Abstract
The experiment was to research the effect of adding different levels of protein mulberry silage to the diet on the growth performance,serum biochemical index and breeding economic benefit of mutton sheep.A total of 100 healthy sheep of similar weight were selected and randomly divided them into five groups with 20 replicates in each group.The mutton sheep in control group were fed a basic feed,while the mutton sheep in experimental groups were fed a experimental feed containing 4%,8%,16%and 32%protein mulberry silage,respectively.The pre-feeding period was one week and the formal experimental period was eight weeks.The results showed that compared with the control group,adding 8%and 16%protein mulberry silage to the diet could significantly reduced the serum urea nitrogen,cholesterol,triglyceride level and rumen acetic acid/propionic acid level of the mutton sheep(P＜0.05),significantly increased the concentration of propionic acid in the rumen of the mutton sheep,as well as the weight gain income and breeding profit of the mutton sheep(P＜0.05).The experiment indicates that adding less than 16%protein mulberry silage can improve some serum biochemical indxes and rumen fermentation function of mutton sheep and increase breeding profits.关键词
