本试验旨在研究中链脂肪酸对脂多糖（LPS）诱导的断奶仔猪肠黏膜免疫屏障损伤的保护作用。将24头（21±1）d、体重为（9.0±0.7）kg的杜×长×大三元杂交断奶仔猪随机分为4个处理组,每个处理组6个重复,每个重复1头猪。试验采用2×2因子设计,2个主因子分别为日粮处理（中链脂肪酸或玉米油）和免疫应激（LPS或NaCl）。预试7 d,试验期为21 d。试验第21天,每个日粮组3个重复注射100μg/kg体重（BW）的LPS,另外3个重复猪注射等量的生理盐水,4 h后屠宰取肠道样品待测。结果表明:中链脂肪酸显著提高了空肠绒毛高度（P

The experiment was conducted to investigate the effects of medium-chain fatty acids(MCFA)supplementation on intestinal mucosal immune barrier function of weanling piglets after lipopolysaccharide(LPS)challenge.A total of 24 weaned piglets of(21±1)d with average body weight(9.0±0.7)kg,were randomly divided into four treatments.All piglets fed control diet for 7 d while they were acclimated to the experimental conditions.The experiment consisted of a 2×2 factorial design,and the main factors included diet(MCFA or corn oil)and immunological cha...
