本试验旨在研究N-乙酰半胱氨酸(N-acetylcysteine,NAC)灌胃对超早期断奶仔猪血浆中游离氨基酸、小肠形态结构及功能的影响.将22头体重为(2.99±0.41) kg的7日龄断奶仔猪随机分为对照组和NAC组,每组1 1个重复,每个重复1头猪.在饲喂人工乳的基础上,NAC组每天每头按50 mg/kg体重进行NAC灌胃,对照组每天每头进行同体积的生理盐水灌胃.于试验第11天按0.1 g/kg体重的剂量给仔猪灌服D-木糖溶液,1h后前腔静脉采血,然后屠宰取小肠组织样,刮取肠黏膜及制作组织切片.结果表明:与对照组相比,NAC组显著提高了超早期断奶仔猪平均日增重(P＜0.05);提高了超早期断奶仔猪血浆中谷氨酰胺、胱氨酸、γ-氨基丁酸水平...

The study was conducted to investigate the effects of intragastric administration of N-acetylcysteine (NAC) on plasma free amino acid composition and intestinal morphology function of ultral-early weanned pigs.The 22 weight (2.99±0.41) kg of 7-day-old weaned piglets were randomly divided into control group and NAC group.Each group had 11 replicates.The two groups were fed a basal milk,the NAC group were fed NAC with 50 mg/kg body weight per day by intragastric administration,and the control group were fed the same volume of saline per day.On d...
