摘  要：
选用96头平均体重为(5.27±0.49)kg的杜×(大×长)断奶仔猪,按完全随机区组设计分为4组,每组4个重复,每重复6头(公母各半),各组仔猪分别饲喂含0%、0.125%、0.25%和0.50%谷氨酰胺二肽的试验饲粮,研究不同水平的谷氨酰胺二肽对断奶仔猪生产性能、细胞免疫及血液生化指标的影响。结果表明,饲粮中添加0.125%~0.50%谷氨酰胺二肽可改善21日龄断奶仔猪饲料利用率、增强细胞免疫功能、提高血清生长激素水平、降低血清皮质醇水平;高剂量(0.50%)谷氨酰胺二肽可显著提高血清超氧化物歧化酶水平;根据各项测定指标综合结果确定断奶仔猪饲粮中谷氨酰胺二肽适宜添加水平为0.125%~0.25%。

摘  要：
Ninety six crossbred Duroc×(Landrace×Largewhite) weanling piglets weighing (5.27±0.49) kg were randomly allocated to 4 treatments , 4 replicates of 6 piglets each (half male, half female). Piglets per treatments were respectively fed one of the experimental diets supplemented with glutamine dipeptide at a level of 0%, 0.125%, 0.25% and 0.50% , to study effect of the different levels of glutamine dipeptide in diet on the growth performance, cell immunity and serum biochemical index of weanling piglets. The result indicated that the supplement of 0.125%~0.50% glutamine dipeptide in diets improved feed conversion rate, strengthened cell immunity, increased serum growth hormone concentration and decreased cortisol concentration. High supplemental level of glutamine dipeptide (0.50%) significantly increased serum SOD value. Optimum supplemental level of glutamine dipeptide in diet for weanling piglets were 0.125% ~0.25%.
