蛹虫草发酵物对威宁牛生长性能和血清免疫功能的影响
Effects of the fermented Cordyceps militaris on the growth performance and immune function in serum of Weining cattle
摘要
Abstract
[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.关键词
