甘氨酰-L-谷氨酰胺对断奶仔猪生长性能及肠道吸收功能的影响

Effect of GLY-L-GLN on Growth Performance and Intestinal Absorption Ability in Weaned Piglets

选择108头28日龄断奶的杜大长仔猪,分别饲喂含0%,0.15%,0.3%,0.45%和0.6%甘氨酰L谷氨酰胺(GLYLGLN)和1%谷氨酰胺(GLN)的日粮。试验表明:日粮中添加0.3%的GLYLGLN和1%的GLN可显著(P<0.05)提高断奶仔猪平均日增重,降低腹泻率。添加适宜水平的GLYLGLN和1%的GLN可提高断奶后7,14和21d的血清D木糖浓度(P<0.05)。

One hundred and eight piglets weaned at 28 d were divided into six groups（0%, 0.15%, 0.3%, 0.45%, 0.6% GLY-L-GLN and 1% GLN supplementation） for 21 d thai. The results of growth performance showed that 0.3% GLY-L-GLN and 1% GLN in diets could improve growth performance and reduce the percentage of diarrhea significantly （P 〈 0.05）. The serum D-xylose concentrations in piglets fed 0.15%, 0.3%, 0.45% GLY-L-GLN and 1% GLN diets were significantly higher than that in piglets fed control diet（ P 〈 0.05）.
