试验旨在研究谷氨酰胺(Gln)对灌服大豆分离蛋白(SPI)仔猪肝脏和肌肉抗氧化功能及肝脏形态结构的影响.将24头7日龄健康仔猪(杜×长×大)随机分为3组:对照组、SPI组、SPI+Gln组,每组8个重复,每个重复1头猪.试验第1～5 d各组仔猪均饲喂人工乳,试验第6～7 d SPI组和SPI+Gln组每头仔猪饲喂含大豆分离蛋白(10 g/kg BW)的人工乳,对照组饲喂含酪蛋白(7.8 g/kg BW)的人工乳.试验第8～10 d SPI + Gln组灌服Gln(250 mg/kg BW),其余2组灌服丙氨酸(305 mg/kg BW).试验第11 d屠宰仔猪,取肝脏、腓肠肌、背最长肌组织样品,检测抗氧化酶活性和氧化产物的含量,并制作苏木素-伊红染色肝脏切片.结果表明,SPI可诱导肝...

The aim of this study was to investi-gate the effects of glutamine(Gln) on the antioxi-dative capacity of liver and muscle, as well asthe liver morphology in piglets fed with soy pro-tein isolate(SPI). Twenty-four 7-day-old healthypiglets(Duroc × Landrge × Large White) were randomly allocated to three groups: control group, SPI group, and SPI + Gln group, with 8 replicates(pigs) in each group. On the day 1 to 5 of the experiment, the piglets of each group were fed with milkreplacer. On the day 6 to 7 of the trial, piglets in the SPI group and...
