小尾寒羊、特克塞尔羊×小尾寒羊和杜泊×小尾寒羊杂一代羔羊生长发育研究

Study on the Growth of Small-tail Han Sheep,Texel×Small-tail Han Sheep and Dorper Small-tail Han Sheep

试验选用小尾寒羊的羔羊,特克塞尔(♂)与小尾寒羊(♀)杂一代(特寒),杜泊与小尾寒羊杂一代(杜寒)羔羊共计68只对其生长发育性能进行研究。结果表明,特寒,杜寒杂一代羔羊初生重较小尾寒羊分别提高19.76%和14.53%;3月龄断奶体重较小尾寒羊分别提高46.37%和44.13%;6月龄特寒、杜寒杂一代体重分别为49.0和48.7 kg。从出生到6月龄体尺测定结果表明特寒、杜寒杂一代与小尾寒羊相比,胸围、尻宽、体长、体高变化差异显著。

The experiment select total 68, Small-tail Han sheep F1 （ HF1）, Texel × Small-tail Han sheep F1 （THF1） and Dorper Small-tail Han sheep FI（DHF1） on the productive performance. The results indicate that the birth weight of THF1 and DHF1 increased 19.76 % and 14.53 % than HF1 respeetively; the weighe during 3 Months increased 46.37 % and 44.13 % respeetively; the weight during 6 months is 49.0±2.35 kg and 48.7±0. 24 kg respectively. The body length, body height and chest girt of THF1 and DHF1 enhance signifieiently than HF1 from birthing to 6 month-age.
