本研究旨在通过猪消化代谢试验测定浓缩脱酚棉籽蛋白(CDCP)生长猪消化能,同时研究其对仔猪生长性能、血清生化指标和养分表观消化率的影响。试验选取65日龄、体重(38.80±2.60) kg的“杜×(长×大) ”健康阉公猪8头,随机分成2组(每组4个重复,每个重复1头猪),分别饲喂基础饲粮和试验饲粮(80%基础饲粮+20% CDCP),单笼饲养,采用交叉法进行消化代谢试验测定消化能。然后选取(31±2)日龄、体重(10.00±0.60) kg的“杜×(长×大) ”健康仔猪132头,按随机区组设计分成2组(对照组和CDCP组),每组6个重复,每个重复11头猪。对照组饲喂基础饲粮(鱼粉用量为4%),CDCP组饲喂试验饲粮(利用CDCP完全替代基础饲粮中...

The purpose of this study was to determine the concentrated degossypolized cottonseed protein (CDCP) digestive energy for growing pigs through pig digestive metabolism experiment, and to study effects of CDCP on growth performance, serum biochemical indexes and nutrient apparent digestibilities of piglets. Eight healthy 65-day-old “Duroc×Landrace×Large White” barrows with body weight of (38.80±2.60) kg were selected and randomly divided into 2 groups with 4 replicates per group and 1 pig per replicate. Pigs in 2 groups were fed with basal ...
