本试验旨在研究日粮中添加复合氨基酸对断奶仔猪免疫功能以及肠道能量和氨基酸水平的影响.将16头体重(4.83±0.16)kg的(21±3)日龄断奶仔猪随机分为对照组和试验组,每组8个重复,每个重复1头猪.对照组饲喂基础日粮+0.99%的丙氨酸(与试验组等氮),试验组饲喂基础日粮+1.00%的复合氨基酸(谷氨酸:谷氨酰胺:甘氨酸:精氨酸:N-乙酰半胱氨酸=10:4:4:2:1).于试验的第21天采集样品.结果表明:与对照组相比,试验组降低了断奶仔猪的腹泻率、血液白细胞和单核细胞的数量以及回肠黏病毒抗性蛋白-1 (MX1 )和干扰素诱导蛋白-1(IFIT1 )基因的相对表达量(P＜0.05);有降低15～21 d耗料增重比的趋势(P＜0.1);提高了血液...

The study was to investigate the effects of dietary supplementation with a compound of amino acid blend on the immune function,intestinal energy and amino acid levels of weaned piglets.A total of 16 piglets were(average body weight of 4.83±0.16 kg,21±3-day-old of age)randomly allocated into two groups.The control group was fed the based diet supplemented with 0.99%alanine(equal nitrogen to that in the experimental group),whereas the experimental group was fed the basal diet supplemented with 1.00%compound of an amino acid blend(AAB;glutamate:...
