高寒牧区牧草枯黄期陶赛特肉羊羊羔补饲育肥试验

摘要

陶赛特肉羊在无补饲、无棚圈的高寒牧区具有较强的适应能力，产肉性能高，耐粗饲。陶赛特肉羊羊羔早期生长发育快，育肥性能好、肉质嫩、无膻味、不腻口，是青海省肉羊生产中的宝贵资源。每年的十月份气温急剧下降，牧草进入枯黄期，但还有部分羔羊未达到出栏体重。为充分达到其早期发育快的特点，生产优质羔羊肉，促进当年羔羊出栏，已达到冬季羊肉均衡上市的目的，于2007年10月20日-12月20日进行了补饲育肥试验，陶赛特肉羊羔羊在放牧加补饲精料颗粒料自由采食条件下进行短期育肥50d，平均体重和日增中分别达到35．43kg和114．4g，较对照组提高5．51kg和10．2g，表明在冬季来临时对陶赛特肉羊羔羊进行放牧加补饲精料育肥具有一定的增重潜力。%Dorset sheep has good adoption ability in Alpine region with producing higher meats, growing fast, good fatten performance, good taste, is precious resource in Qinghai province.
