摘要
选用21日龄的杜×长×大三元杂交早期断奶仔猪160头,按窝别、性别和体重分为2组,即对照组为基础日粮,试验组为基础日粮+0.1%复合卵黄抗体粉剂。表明:21～35日龄阶段,试验组比对照组平均日增重高15g(P<0.05),采食量高2.4g·d-1(差异不显著),料重比下降,腹泻率下降9.9%(P<0.05)。35～70日龄阶段,试验组比对照组平均日增重高6.5g(差异不显著),采食量下降15g·d-1,料重比低,腹泻率下降1.5%(P<0.01)。
To investigaee effect of egg yolk antibodies on performace and diarrhoea rate,160 early weaned piglets (Landrance×Large white×Middle Yakshire) of 21 day old were allotted to two treatments.The first control group use based on biet.In trial treatment addition with 0.1 % compound egg yolk antibodies power.The result of the experiment showed:It is 21～35 day old,trial group than control group improved 15 g(P<0.05) on average daily gain,feed intake improved 2.4 g·d-1 (P>0.05), feed/weight dropped,the suffering from diarrhoea rate dropped by 9.9%(P<0.05).35～70 day old,trial group than control group improved 6.5 g(P>0.05), feed intake dropped 15 g·d-1,feed/weight dropped,the suffering from diarrhoea rate dropped by 1.5 %(P<0.01).
