本试验旨在研究饲粮及饮水中添加复合有机酸对断奶仔猪生长性能、胃肠道内容物pH、血清生化指标、营养物质表观消化率以及空肠黏膜中分泌型免疫球蛋白A( SIgA)含量的影响。试验选取21日龄、体重为(6.0±1.0) kg的健康“杜×长×大”三元杂交断奶仔猪120头,随机分成Ⅰ、Ⅱ、Ⅲ、Ⅳ组,每组5个重复,每个重复6头。Ⅰ组为对照组,饲喂基础饲粮;Ⅱ组为抗生素组,在基础饲粮中添加0.05%的弗吉尼亚霉素预混料(弗吉尼亚霉素含量为50%);Ⅲ组为有机酸化剂组,在基础饲粮中添加0.2%的复合有机酸B,且在饮水中添加0.1%的复合有机酸A;Ⅳ组为有机酸化剂组,在基础饲粮中添加0.2%的复合有机酸B和0.3%的复合有机酸C。试...

This experiment was conducted to investigate the effects of dietary and drinking water supplemented compound organic acids on growth performance, gastrointestinal tract pH, serum biochemical indicators, apparent nutrient digestibility and secreted immunoglobulin A (SIgA) content in the jejunal mucosa of weaning piglets. In the test, a total of 120 healthy 21-day-old Duroc×Landrace×Yorkshire ternary weaning piglets with body weight of (6.0±1.0) kg were randomly divided into 4 groups, namely, groups Ⅰ, Ⅱ, Ⅲ and Ⅳ. Each group contained 5 re...
