Effects of Probiotics Supplementation on Growth Performance,Immune Function and Blood Biochemical Indexes of Hu-sheep Lambs
The experiment was conducted to investigate the effects of different treatment groups on growth performance,im-mune function and blood biochemical indexes of lambs.Thirty-six healthy Hu sheep lambs with similar body weight were ran-domly divided into control group(basal diet),trial group Ⅰ(70％basal diet+30％alfalfa meal)and trial group Ⅱ(70％basal diet+30％alfalfa meal+1％probiotics).The experiment lasted for 60 d.The results showed as follows:there were no signifi-cant differences in final weight,dry matter intake and ratio of feed to gain among all groups(P＞0.05),and the average daily body gain in group Ⅱ increased by 10.40％compared to the control group(P＜0.05),but no significant difference between group Ⅰ and control group(P＞0.05).The levels of aspartate aminotransferase and alkaline phosphatase in group Ⅱ were sig-nificantly lower than those in control group(P＜0.05).The levels of triglycerides in groups Ⅰ and Ⅱ were significantly lower than those in control group(P＜0.05).The IgG content in group Ⅱ was significantly higher than that of the other two groups(P＜0.05),but the IgA and IgM contents were not significantly different among groups(P＞0.05).Therefore,dietary supple-mentation with probiotics and forage fiber can improve growth performance of lambs,improve some serum biochemical inde-xes,and enhance the immune function and body resistance of lambs.
