摘要
【目的】选育出繁殖率高、生长发育速度快、屠宰率高的肥羔品种。【方法】选取相同年龄的萨福克羊(♂)×(♀)阿勒泰大尾羊杂交一代、陶赛特羊(♂)×(♀)阿勒泰大尾羊杂交一代和阿勒泰大尾羊后代各30只并按照品种不同分成3组,在相同的营养水平下对比其90 d的生长发育情况。【结果】试验羊生长发育指标统计分析表明,萨福克羊(♂)×(♀)阿勒泰大尾羊杂交一代和陶赛特羊(♂)×(♀)阿勒泰大尾羊杂交一代的体重、体高、毛质、屠宰率等指标均优于阿勒泰大尾羊后代羔羊。【结论】萨福克羊(♂)×(♀)阿勒泰大尾羊杂交一代与阿勒泰大尾羊后代羔羊相比,生产性能更加优良。
[Objective]The main purpose of the present study was to select and breed the fat lamb varieties with high breeding coefficient, quick development and high dressing percentage. [ Method]The total 30 lambs were selected from three pilot groups with F1 Suffollk (♂)×(♀) Ahay, F1 Poll Dorset (♂)×(♀) Ahay group and Poll Dorset (♂)×(♀) Altay group were superior to those of Altay lamb group. [Result]The results showed that the body weight, height and wool quality of the F1 Suffollk (♂)×(♀) Altay group and F1 Poll Dorset were superior to those of Altay lamb group. [ Conclusion]The production performance of F1 Sufforllk Altay group were superior to that of Altay lamb group.
