蛋氨酸对宫内发育迟缓断奶仔猪血浆生化指标和肠道消化吸收功能的影响
Effects of methionine on plasma biochemical parameters and intestinal digestive and absorptive function in intrauterine growth-retarded weanling piglets
摘要
Abstract
Objective:The aim of this study was to investigate the effects of methionine on plasma biochemical parameters and intestinal digestive and absorptive function in weanling piglets with intrauterine growth retardation (IUGR).Methods:After weaning(21 d of postnatal age),thirty female normal birth weight(NBW)piglets were assigned to receive the control diet (NBW-CON),and sixty same-sex IUGR piglets were randomly assigned to receive the control diet (IUGR-CON)or the control diet supplemented with 0.12％ methionine(IUGR-MET) for 28 d,each group consisted of six replicates with five piglets per replicate.Results:Compared with NBW-CON piglets,the plasma urea nitrogen content of piglets in IUGR-CON group was increased,whereas the plasma total protein and D-xylose contents were significantly decreased (p ＜ 0.05).In addition,the apparent digestibility of crude protein and gross energy,the activity of trypsin in the jejunal digesta,and the activities of alkaline phosphatase and Na+-K+-ATPase in the jejunal mucosa of piglets in IUGR-CON group were also significantly decreased(p ＜ 0.05).Compared with piglets in IUGR-CON group,IUGR-MET piglets had decreased plasma urea nitrogen content,whereas increased plasma D-xylose content (p ＜ 0.05).Dietary supplementation of 0.12％ methionine significantly alleviated the decreased apparent digestibility of crude protein,the activity of trypsin in jejunal digesta,and the activity of Na+ -K +-ATPase in jejunal mucosa(p ＜0.05).Conclusion:Dietary supplementation of 0.12％ methionine significantly decreased plasma urea nitrogen content and partially improved digestive and absorptive function in the intestine of IUGR weanling piglets.关键词
