本试验旨在研究L-亮氨酸（Leu）对猪流行性腹泻病毒（PEDV）感染幼龄仔猪血液指标和空肠免疫相关基因m RNA表达量的影响,探索Leu对PEDV感染仔猪应激的缓解作用。选用30头体重相近的7日龄PEDV阴性仔猪,随机分为3个处理组：对照组、PEDV组和PEDV＋Leu组,每个处理10个重复,每个重复一头猪。试验期10 d（7日龄~16日龄）。从第0天开始对PEDV＋Leu组按2.8 g/kg体重饲喂Leu,而对照组和PEDV组均按4.1 g/kg体重饲喂L-丙氨酸。第7天早上对PEDV组和PEDV＋Leu组采用口服的方式接种106.5TCID50的PEDV,同时对照组采用口服的方式接种等剂量的生理盐水,3 d后（16日龄）取血液和肠道样品。结果表明：与对照组相比...

This experiment was conducted to study the effects of leucine （Leu）on blood biochemical parameters and immune-related genes in the jejunum mucosa of piglets infected by PEDV,thereby to determine whether Leu can relieve the stress on piglets caused by PEDV.A total of 30 7-day piglets of similar weight without PEDV were selected and randomly di-vided into three treatment groups：control group,PEDV group, PEDV＋Leu group.Each group had 10 replicates with 1 piglet each.The experiment lasted for 10 days.Piglets in PEDV ＋ Leu group were fed with L...
