饲料精粗比对肉牛生长性能、免疫功能的影响
Effects of Feed Concentrate to Roughage Ratio on Growth Performance and Immune Function of Beef Cattle
摘要
Abstract
This study aimed to evaluate the effects of different concentrate-to-roughage ratios on the growth performance and immune function of beef cattle.Sixty Simmental crossbred beef cattle were randomly assigned to four groups with concentrate-to-roughage ratios of 75∶25,70∶30,65∶35,and 60∶40,respectively,for a 90-day feeding trial.Cattle fed diets with ratios of 65∶35 and 60∶40 showed significantly higher final body weight and average daily gain(P＜0.05),while their feed-to-gain ratio was significantly lower(P＜0.05).Serum immunoglobulin G(IgG)and interleukin-4(IL-4)levels were significantly increased in both groups(P＜0.05),and the 60∶40 group also exhibited higher IgM and IgA concentrations(P＜0.05).The concentrate-to-roughage ratio significantly affects growth and immune function in beef cattle,with the 60∶40 ratio providing the most favorable results under the conditions of this study.关键词
