不同比例苦豆子替代苜蓿对伊拉肉兔生长性能、血清生化指标和免疫指标的影响OA北大核心CSTPCD

The aim of this experiment was to study the effects of alfalfa substitution with different proportions of Sophora alopecuroides L.on the growth performance,serum biochemical indexes,and immune indexes of Hyla rabbits.A total of one hundred and twenty 35-day-old healthy Hyla rabbits with similar body weight were randomly divided into four groups with five replicates per group and six rabbits per replicate.The rabbits in the control group were fed a basal diet,and the others in the experimental groups were fed 4％,8％,and 12％Sophora alopecuroides L.instead of alfalfa in the basal diet,respectively.The pre-test lasted for 14 days and the formal test lasted for 56 days.The results showed that compared with the control group,the average daily gain and body weight at the 28th and 56th days in 4％group were significantly increased(P＜0.05),and the feed to gain ratio was significantly decreased(P＜0.05).The live weight,half evisceration rate,and full evisceration rate were significantly increased(P＜0.05).Compared with the control group,the serum globulin(GLB)content of experimental groups was significantly decreased(P＜0.05),and the activities of γ-glutamyl transpeptidase(GGT),alanine aminotransferase(ALT)and alkaline phosphatase(ALP)were significantly increased(P＜0.05).Serum glucose(GLU)and total cholesterol(TG)concentrations in 8％and 12％groups were significantly decreased(P＜0.05).Thymus weight and thymus index in 8％group were significantly decreased(P＜0.05),and liver index was significantly increased(P＜0.05).The concentrations of serum immunoglobulin G(IgG)and immunoglobulin M(IgM)in 4％group were significantly increased(P＜0.05).The results show that when the upper limit of Sophora alopecuroides L.is 8％,and the supplemental amount of Sophora alopecuroides L.is 4％,the breeding effect of meat rabbits is the best.
