豫北小尾寒羊的适应性和种质特性研究

在豫北随机选取了140只小尾寒羊，对其进行了形态学和行为学观察，进行了生长发育和生理指标的测定，考查了遗传特性，了解了繁殖情况与疾病情况等。研究表明：小尾寒羊品种特征突出，适应性强，耐粗饲，抗病力高，生长发育快，产肉性能良好，遗传性稳定等。但仍存在着个体发育不整齐，剪毛量不高，毛质较差等缺点。

The Research about Adaptability and Genetic Characteristic of the Yubei Small Tail Sheep

140 small tail sheep were selected in the north of Henan. They were observed on the sheep's appearance science and behavior science, and were measured on the growth and physiology target, were investigated on the genetic characteristic, were detected about the situation on the fecundity and disease etc. The Study shows: The small tail sheep breed characteristic is outstanding, the adaptability is strong, the small tail sheep bear the extensive feeding,the anti-disease dint is high, growing and growth quickly,have a good production on mutton, have steady heredity function, etc. But they still exist some shortcoming, for example growth not tidy, the wool yield is not high, the wool quality is worse, and so on.
