摘要
试验以杜泊、多赛特、德国肉用美利奴羊分别作为父本,以萨福克与小尾寒杂交后代作为母本进行三元杂交,对杂交羔羊的生产性能指标进行对比分析。结果表明,杜×萨寒[杜泊♂×(萨福克♂×小尾寒羊♀)♀]宰前空腹重、胴体重、屠宰率3项指标分别达到了43.0 kg、22.4 kg和52.07%,均显著高于多×萨寒[多赛特♂×(萨福克♂×小尾寒羊♀)♀]和德×萨寒[德国肉用美利奴羊♂×(萨福克♂×小尾寒羊♀)♀];杜×萨寒日增重达到了262.3 g,高于多×萨寒和德×萨寒,且显著高于德×萨寒。
Three-way crossbreeding trials were conducted using Dorper ram, Poll Dorset ram, German mutton merino ram and ewe hybrid of Small-tail Han and Suffolk, respectively. The productive performance of the hybrids was determined. The results showed that the pre-slaughter empty body weight, carcass weight and slaughtering percentage of hybrids of Dorper×Small-tail Han and Suffolk reached 43.0 kg, 22.4 kg and 52.07%, respectively, and the three indicators were all higher than those of hybrids Poll Dorset×Small-tail Han and Suffolk and German mutton merino ×Small-tail Han and Suffolk; the daily gain of hybrids of Dorperx Small-tail Han and Suffolk reached 262.3 g which was higher and significantly higher than that of hybrids of Poll Dorset×Small- tail Hart and Suffolk and German mutton merino×Small-tail Han and Suffolk, respectively.
