蛹虫草发酵物对威宁牛生长性能和血清免疫功能的影响OA
Effects of the fermented Cordyceps militaris on the growth performance and immune function in serum of Weining cattle
[目的]开发新型中草药饲粮,为饲料替抗和肉牛健康养殖提供科学依据.[方法]选取40头健康、体重相近(200±10 kg)的12月龄威宁牛,随机分为4组(每组10头),分别饲喂基础饲粮(对照组,CK)及添加0.8％(T1组)、1.5％(T2组)、2.2％(T3组)蛹虫草发酵物的饲粮,预试期15 d,正试期90 d.测定各组牛的体重、采食量、体尺等生长性能指标以及血清免疫球蛋白(IgG、IgA、IgM)含量.[结果]T2组(1.5％添加量)威宁牛的平均日增重显著提高(P<0.05),较CK组提高12.27％,料重比较CK组显著降低19.64％(P<0.05);90 d时,血清中IgG、IgA、IgM含量较CK组分别显著提高30.14％、46.15％、40.91％(P<0.05).[结论]蛹虫草发酵物的适宜添加量为1.5％,能明显提升威宁牛的免疫功能.
[Objectives]A new type of herbal feed was developed to provide scientific basis for the replac-ing antibiotics with feed and the healthy farming of beef cattle.[Methods]40 healthy and approximately weighted 200±10 kg and 12-month-old Weining cattle were randomly divided into 4 groups with 10 cattle in each group.They were fed with basic diet(control group,CK)and diet supplemented with 0.8％(T1 group),1.5％(T2 group),and 2.2％(T3 group)fermented Cordyceps militaris,respectively.The pre-test period was 15 days,and the main test period was 90 days.The indexes of growth performance including body weight,feed in-take and body size,and the content of immunoglobulins including IgG,IgA and IgM in serum of each group of cattle were measured.[Results]The average daily weight gain of Weining cattle in the T2 group was signifi-cantly increased(P<0.05),with an increase of 12.27％compared to that in the CK group.The feed-to-weight ratio of the T2 group was significantly reduced by 19.64％compared to that of the CK group(P<0.05).The content of IgG,IgA,and IgM in the serum of the T2 group at 90 days was significantly increased by 30.14％,46.15％,and 40.91％,respectively,compared to that of the CK group(P<0.05).[Conclusions]The appropriate addition amount of fermentation product of Cordyceps militaris is 1.5％,which can significantly enhance the immune function of Weining cattle.
