In order to explore the effects of compound probiotics on the growth performance,sheep nutrient digestion,serum biochemical indexes and economic benefits of mutton sheep,150 mutton sheep were randomly divided into 5 groups,each group had 5 replicates,and each group was 6 sheep.0(group A),0.5%(group B),1.0%(group C),1.5%(group D)and 2%(group E)were added to the basic diet of meat sheep.The results showed that in terms of growth performance index,the final weight and average daily weight gain of group B,C,D and E beef cattle with compound probiotic preparations were significantly higher than that of group A(P＜0.05).In terms of slaughter performance and serum biochemistry,group B,C and D E were better than group A(P＜0.05).In terms of economic benefit index of aquaculture,group D was significantly better than other groups in economic benefit index(P＜0.05).Conclusion:Adding 1.5%compound probiotics to mutton sheep feed can improve its growth performance,slaughter performance,serum biochemical index and improve the economic benefit of breeding.
