微生态制剂对高山美利奴羊生产性能、养分表观消化率、产毛性能和血清生化指标的影响OA北大核心CSTPCD
Effects of microecological agents on production performance,nutrients apparent digestibility,wool production performance,and serum biochemical indexes of Alpine Merino sheep
试验旨在探究微生态制剂对高山美利奴羊生产性能、养分表观消化率、产毛性能和血清生化指标的影响.选择2～3岁、体重相近的高山美利奴母羊90只,随机分为3组,每组3个重复,每个重复10只母羊.对照组、试验Ⅰ组和试验Ⅱ组分别在饲粮中添加0、1％和2％的微生态制剂.预试期10 d,正式试验期120 d.结果显示,与对照组相比,试验Ⅰ组、Ⅱ组的羔羊初生重显著提高(P＜0.05),母羊产毛量和毛长度显著增加(P＜0.05).试验组母羊的干物质、粗蛋白、粗脂肪、…查看全部>>
The purpose of this experiment was to investigate the effects of microecological agents on the production performance,nutrients apparent digestibility,wool production performance,and serum biochemical indexes of Alpine Merino sheep.Ninety Alpine Merino ewes aged 2～3 years and of similar weight were randomly divided into three groups with three replicates in each group and ten ewes in each replicate.The control group,the test group Ⅰ and the test group Ⅱwere …查看全部>>
