摘要 试验选用60头21d断奶、体重均一的杜长大仔猪。按单因素完全随机化设计随机分为2组,一组为对照组,饲喂基础日粮;一组为试验组,基础日粮添加0.5%的谷氨酰胺,研究谷氨酰胺处理对断奶仔猪小肠黏膜形态变化的影响。在断奶当天及断奶后7d和14d每个处理随机选取3头仔猪屠宰,取小肠组织,测定肠黏膜的形态结构变化。结果表明:日粮中添加谷氨酰胺提高了小肠绒毛高度和固有层厚度及皱褶深度。 Sixty crossbred piglets (Durocxlandracex^orkshire)weaned at 21 days of age were divided into 2 treatments based on weight and gender.Piglets in treatments were fed basal diet and basal diet supplemented with 0.5 % glutamine respectively.The effect of glutamine on morphology of intestine mucosal of early weaned piglets was studied.The VH and LPD traits of intestine mucosal at the age of 21,28,35 d were measured.The results showed that both VH and LPD of weaned pigs increased with supplementation of glutamine.
