大豆-玉米混合青贮对肉牛生长性能、养分表观消化率及瘤胃发酵参数的影响
Effects of soybean-corn mixed silage on growth performance,nutrient apparent digestibility,and rumen fermentation parameters of beef cattle
摘要
Abstract
The experiment was conducted to study the effects of soybean-corn mixed silage on the growth performance,nutrient apparent digestibility,and rumen fermentation parameters of beef cattle.A total of 48 Simmental crossbred cattle with a body weight of about(350±23)kg were randomly divided into three groups,each group had four replicates,with four beef cattle per replicate.The control group was fed whole corn silage,and 50％and 100％whole corn silage were replaced by soybean-corn mixed silage in groups Ⅰ and Ⅱ,respectively.The pre-test period was seven days and the formal test period was 60 days.The results showed that compared with the control group,the average daily weight gain of beef cattle in group Ⅱ was significantly increased(P＜0.05),and the ratio of feed to gain was significantly decreased(P＜0.05).The apparent digestibility of acid detergent fiber and phosphorus in group Ⅰ and Ⅱ,and neutral detergent fiber in group Ⅱ were significantly increased(P＜0.05).The weight gain income and profit of beef cattle in group Ⅱ were significantly increased(P＜0.05).The study indicates that replacing corn silage with 100％soybean-corn mixed silage can promote the growth of beef cattle,enhance the nutrient apparent digestibility and economic benefits.关键词
