摘    要:选21日龄断奶的杜大长仔猪72头,按试验要求分为2组,每组3个重复,每重复12头。分别饲喂基础日粮和含1%谷氨酰胺(Gln)日粮,试验期21 d,在断奶后0 d、7 d和14 d分别屠宰取小肠测重,并取十二指肠、空肠、回肠测定绒毛高度和隐窝深度。试验结果表明:断奶后7 d,日粮中添加Gln可显著提高仔猪的平均日增重和小肠相对重量,提高十二指肠和空肠绒毛的高度,降低十二指肠和空肠的隐窝深度;断奶后14 d,日粮中添加Gln对断奶仔猪的生长和肠道形态发育影响与基础日粮组相比差异不显著。

关 键 词:谷氨酰胺  小肠黏膜  断奶仔猪  小肠绒毛

Abstract:Seventy-two piglets weaned at 21d were allocated to two treatments,each of which had 3 replicates,12 piglets per replicate.The control treatment was fed basal diet,while the experimental group was fed basal diet supplemented with 1% glutamine(Gln).The experiment lasted for 21days.The results showed that 1% Gln in diets could significantly improve growth performance and relative intestinal weight at 7d post weaning.Piglets fed with glutamine had significantly higher intestinal villus height and lower crypt depth at 7d post weaning,but at 14d post weaning,the effects of Gln on growth performance and intestinal mucous development were not significant.
Keywords:weaned piglet  glutamine  intestinal mucous  intestinal villi
