摘要: 76头杜洛克、长白、大约克三元杂交仔猪(随机分为4组,每组19头)进行饲养试验,探讨外源性Gln对28±2日龄断奶仔猪生产性能和腹泻的影响。试验结果表明:与对照组相比,试验组平均日增重升高[其中1.2%Gln组差异显著(P<0.05);平均日采食量降低(P>0.05)];饲料转化率降低[其中1.2%Gln组差异显著(P<0.05);腹泻率、腹泻频率及死亡率都降低(P>0.05)]。提示:在早期断奶仔猪日粮中添加外源性Gln,可以提高饲料转化率,促进仔猪生长,降低仔猪腹泻率和死亡率。

Abstract: 76 piglets(divided into 4 groups, 19 piglets each group ) were used to investigate the effects of glutamine on the growth performance and diarrhoea of piglets weaned at 28±2 days. The results showed that: The ADG of groups supplied with glutamine increased [The group of 1.2%Gln obviously increased (P<0.05)]. The ADFI of groups supplied with glutamine decreased (P>0.05). The feed conversion rate of groups supplied with glutamine decreased [The group of 1.2%Gln obviously increased (P<0.05)]. The diarrnhoea rate, diarrhoea frequency and mortality of groups supplied with glutamine also decreased compared with the control group (P>0.05). The results suggested that the weaned diet with the addition of glutamine could improve feed conversion rate and the performance of early piglets, reduce the rate of diarrhoea and mortality.
