黄芪多糖对断奶仔猪生产性能的影响

为了分析黄芪多糖对断奶仔猪生产性能的影响,选择28日龄的杜大长三元杂交断奶仔猪108头,公母各半,体重接近。随机分为4组,每组27头,每组3圈,每圈9头。对照组饲喂基础日粮,Ⅰ、Ⅱ、Ⅲ组为试验组,分别在基础饲粮中加入黄芪多糖200、500 mg/kg和1000 mg/kg,试验期28 d。结果表明:含黄芪多糖日粮对仔猪的日增重、营养物质消化率、料肉比及腹泻率均有所改善,添加组与对照组在腹泻率方面差异显著(P<0.05),其中以添加500mg/kg为宜。

Effects of astragalus polysaccharide on growth performance of weaning piglets

The study was conducted to investigate the effect of astragalus polysaccharide(APS) on growth performance of weaning piglets.54 male and 54 female crossbred(Duroc·Landrace×Yorkshire) weaning piglets at age of 28 days were divided into four groups randomly.There were 27 piglets in each group which were raised in three pens with 9 piglets in each pen.The piglets of control group,treatment Ⅰ,treatment Ⅱ and treatment Ⅲ were fed with basal diet,basal diet +200 mg/kg APS,basal diet + 500 mg/kg APS and basal diet + 1000 mg/kg respectively.The experiment lasted for 28 days.The results showed that the average daily gain,feed/gain ratio and diarrhea incidence(P < 0.05) of piglets in group Ⅰ,group Ⅱand groupⅢ were improved respectively compared with control group,and group Ⅱ had the best effects.
