摘要
试验旨在研究日粮中添加不同蛋白源对保育猪生长性能的影响。试验选用体重相近的21日龄"杜×长×大"三元杂交保育猪144头,随机分为4组,A组为对照组,含进口鱼粉3%,B、C、D分别为试验组,分别含进口肠膜蛋白粉2%、破壁酵母粉3%和血浆蛋白粉3%,试验期14 d。结果表明,各处理组对保育猪平均日采食量、平均日增重和料肉比的影响不显著(P>0.05),但添加进口鱼粉3%可较好改善保育猪平均日增重和料肉比,添加破壁酵母粉3%可较好改善保育猪平均日采食量。
This experiment was conducted to investigate the effects of different dietary protein sources on growth performance of nursery pigs.One hundred and forty-four nursery pigs at the age of21d were randomly divided into four groups.Group A was the control group,containing3%imported fish meal,B,C and D were the experimental group,which contained2%of the imported intestinal membrane protein powder,3%of the broken yeast powder and3%of the plasma protein powder respectively and the trail lasted for14days.The results showed that the average daily feed intake,average daily gain and feed conversion ratio of the nursery pigs were not significantly affected by the treatment groups(P>0.05).But the addition of3%imported fish meal could improve the daily average daily gain and feed to meat ratio of the diet pigs,and the addition of3%broken yeast powder could improve the average daily feed intake of the nursery pigs.
