本试验旨在研究亚麻籽油对脂多糖(LPS)刺激断奶仔猪肠黏膜结构和免疫细胞的影响。选择24头(9.15±0.90) kg杜×长×大断奶仔猪,随机分为4组,每组6个重复,每个重复1头猪。试验采用2×2双因子设计,主因子包括:1)饲粮处理(5%玉米油或5%亚麻籽油) ;2)免疫应激(注射生理盐水或LPS) 。饲粮中添加5%玉米油或5%亚麻籽油饲喂21 d,在试验第21天,每组1 / 2的猪腹膜注射100 μg / kg BW的LPS,另外1 / 2的猪腹膜注射等量生理盐水。注射LPS或生理盐水4 h后,将仔猪麻醉屠宰,取肠道样品待测。结果表明:1) LPS刺激显著降低了空肠、回肠绒毛高度和空肠隐窝深度(P

The purpose of this study was to investigate the effects of flaxseed oil on intestinal mucosa structure and immune cells of weaned piglets after lipopolysaccharide （LPS） challenge. Twenty-four Duroc Landrace Yorkshine crossed-bred weaned piglets with average body weight （BW） of （9.15±0.90） kg were randomly divided into four groups with six replicates each and one pig per replicate. The experiment consisted of a 2×2 factorial design, and the main factors included： 1 ） diet treatment （5% flaxseed oil or 5% corn oil） ; 2） immu- nologi...
