摘要
为探究中草药添加剂对育肥期肉羊生产性能的影响,筛选出最佳添加剂量进行推广.该试验选取90日龄小尾寒羊40只,随机分为对照组(A组)、低剂量添加组(B组),中剂量添加组(C组)和高剂量添加组(D组),通过测定末重、增重、平均日增重、日平均采食量、料肉比等几项指标进行比较分析.结果表明,B组在末重、增重、平均日增重、日平均采食量、料肉比与A组相比差异性不显著(P＞0.05),但是与C组、D组相比差异性显著(P＜0.05),且C组的料肉比最低.说明在饲料中添加一定剂量的中草药添加剂有利于育肥期肉羊的增重,降低料肉比,增加养殖效益,推荐使用剂量为在日粮中添加0.6%.
Abstract
In order to study the effect of Chinese herbal medicine additive on the performance of fattening mutton sheep,the optimal additive dosage was screened and popularized.In this experiment,40 small-tailed Han sheep of 90 days old were randomly divided into control group(Group A),low-dose additive group(Group B),middle-dose additive group(Group C)and high-dose additive group(Group D),the final weight,weight gain,average daily weight gain,average daily feed intake and feed-to-meat ratio were measured and compared.The results showed that there was no significant difference between Group B and Group A in final weight,weight gain,average daily weight gain,average daily feed intake,feed-to-meat ratio(P＞0.05),but compared with Group C and Group D,the difference was significant(P＜0.05),and the feed-to-meat ratio of Group C was the lowest.The results showed that adding a certain amount of Chinese herbal medicine additive to feed was beneficial to gain weight,reduce feed to meat ratio and increase breeding benefit.The recommended dosage was 0.6%.
