文档介绍：日粮中添加乳生肽对断奶仔猪生产性能的影响

摘要:为研究不同水平乳生肽在断奶仔猪日粮中的添加效果,选取180头长×大二元杂交仔猪,随机均分为3组,3组分别按如下处理:组1为对照组,饲喂基础日粮;组2和组3分别在基础日粮中添加300和500 mg/kg的乳生肽。试验期50 d,测定仔猪的生产性能,观察仔猪采食、毛色、排粪及其精神状态,记录腹泻、疾病和死亡等典型症状及异常情况等。结果表明,组2仔猪的平均末重、平均日增重、%、%%,%,但差异均不显著;组3的平均末重、平均日增重、%、%%,%,但差异均不显著;各项指标组3均好于�M2,但差异也不显著。组2和组3的腹泻率、发病率以及死淘率极显著低于对照(P中国论文网/8/view-

Abstract:In order to study the effects of lactoferrin on weaned piglets, 180 Landrace×Yordshire weaned piglets were divided into 3 groups randomly, groups 1~3 were treated as follows: ①basal diet; ②basal diet+300 mg/kg lactoferrin; ③basal diet +500 mg/kg lactoferrin. The trial lasted for 50 days. The samples were collected and growth performances, ingestion, hair color, feces and mental state were observed. The results showed that, the average final weight in group 2 and group 3 were greater than control group by % and % respectively; the average daily gain(ADG) in group 2 and group 3 were greater than control group by % and % respectively. The average daily
