The influence of compound probiotics on the growth performance,slaughter performance,serum biochemical index and economic benefits of mutton sheep
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.
