榆林市陕北白绒山羊生产性能调查

Investigation on Production Performance of Northern Shaanxi White Cashmere Goats in Yulin

陕北白绒山羊是经过30多年简单育成杂交方式形成的以产绒为主、绒肉兼用型绒山羊品种,因其耐粗饲、耐寒冷、抗病力强等特性深受陕北农民青睐,逐渐成为榆林市农村经济发展的重要主导产业。本文从品种特征、体型外貌、产绒产肉、体尺体重、繁殖遗传性能及适应性方面入手开展榆林市陕北绒山羊生产性能调查,调查结果表明,与国内其它绒山羊品种相比,陕北白绒山羊具有单位产绒量高、出肉率高、绒质优秀、遗传稳定、群体中选育群间存在着多型变异和频密产羔个体等性能,并在生产性能调查数据基础上,对其饲养管理及陕北白绒山羊发展方向提出合理的意见,为今后我市陕北白绒山羊发展提供一定的参考。

Northern Shaanxi White Cashmere Goat is a cashmere-producing and cashmere-dual cashmere goat breed which has been bred by simple crossbreeding method for more than 30 years. It is favored by farmers in northern Shaanxi because of crude feeding, cold and strong disease resistance. It has gradually become an important leading industry of rural economic development in Yulin. This paper investigates the production performance of Northern Shaanxi Cashmere Goats in Yulin from the aspects of breed characteristics, body appearance, cashmere production, body weight, reproductive genetic performance and adaptability. The results show that compared with other domestic cashmere goat breeds, Northern Shaanxi White Cashmere Goats have high cashmere yield per unit, high meat yield, excellent cashmere quality, genetic stability, and polymorphic variations and frequent lambing individuals among the breeding groups in the population. Based on the investigation data of production performance, reasonable suggestions were put forward on the feeding management and the development direction of Northern Shaanxi White Cashmere Goats in this paper, which could provide some reference for the future development of Northern Shaanxi White Cashmere Goats in our city.
