浅析青海省小尾寒羊的发展现状与方向

Primary Analysis on the Production and Developing Trend of Small-tail Han Sheep in Qinghai

通过对青海省引进、纯繁、推广小尾寒羊的情况调查,适应性观察,以及杂交试验分析表明,从山东梁山、郓城等地引进的小尾寒羊在舍饲,羊舍饲条件下,能够适应青海省海拔较低的农区环境,较好的保持了原产地小尾寒羊的品种特性,产羔率220%,羔羊成活率85.67%。生长发育快,体格高大。小尾寒羊不是一个肉用品种,它的品种特性在于生长发育快、早熟、常年发情和多胎性,利用这一优势的有效途径是经济杂交。以小尾寒羊或其杂种一、二代羊为母本,选用良种肉用公羊进行杂交,建立高效、集约化的肉羊生产体系,生产优质羊肉是青海省小尾寒羊养殖的发展方向。

Tests of introducing, extending, purely and crossly breeding small-tail-Han sheep and its performance were analyzed, its adaptation ability was observed. It was found that under full and semi shelter conditions, the small-tail-Han sheep from Liangshan and Yunchen Sandong province could adapt to the environment in low altitude agriculture area in Qinghai well and maintained the species feature. Averagelly the reproductive rate and lamb surviving rate could reach 220% and 86% respectively. Growing fast and had big size. By commercial cross breeding the sheep potential such as fast growing, early maturing, heating around year and showing multi-embryo performance could be kept. Chosen small-tail Han sheep or its F1 F2 offsprings as matenal and elite meat breed ram as paternal line, set up efficient intensive systems and producing high-qaulity mutton, this is the developing trend of the small-tail Han sheep in Qinghai.
