摘要
该文旨在研究TMR中加入发酵饲料对肉牛生长性能产生的影响,试验选择36头体重接近的西门塔尔杂交肉牛,随机分为3组.结果显示,同对照组比较,试验A组、试验B组肉牛的终末体重都有增加,B组肉牛的每日体增重与平均每日采食重量全部显著增加(P＜0.05);同对照组肉牛比较,A组肉牛的料重比提升了0.03%(P＞0.05),B组肉牛的料重比例下降了0.84%(P＜0.05).20%的发酵饲料替代TMR饲喂肉牛能够促进其生长性能,有效降低料重比,使经济效益提高.
Abstract
The purpose of this paper is to study the effect of adding fermented feed to TMR on the growth performance of beef cattle.Thirty-six Simmental hybrid beef cattle with similar body weight were randomly divided into three groups.The results indicated that the finalbody weight of cattle in both group A and group B increased compared to the control group.The weight gain and daily feed intake of beef cattle in Group B showed a significant increase(P＜0.05).Compared with the control group,the feed-to-weight ratio of the experimental group A increased by 0.03%(P＞0.05),and the feed-to-weight ratio of the experimental group B decreased by 0.84%(P＜0.05).It can be seen that feeding beef cattle with 20%fermented feed instead of TMR can promote the growth performance of beef cattle and effectively reduce the feed-to-weight ratio and thus improve economic benefits.
