【摘要】 【目的】新疆作为我国第二大牧区，具备丰富的绵羊品种资源。全面深入地认识各品种的生产特性以及开发利用现状，对于养殖者依据当地实际情况科学选种，进而挖掘生产潜力、提升养殖效益，有着至关重要的意义。【方法】对新疆13个地方品种绵羊资源的生产特性、开发利用现状进行归纳总结。【结果】在对新疆地方绵羊杂交利用调查中发现，杂交利用可以充分发挥杂种优势，提高后代繁殖、产肉和生长发育性能。然而，在杂交选育过程中，部分杂交后代群体的性能出现下降趋势。针对这一趋势，对新疆绵羊养殖过程中的问题给出具体建议。【结论】充分了解现有品种资源的优势和短板，优化绵羊饲养管理模式，强化技术推广力度，为新疆绵羊品种（系）遗传改良和生产性能的提升提供理论依据，进而推动新疆畜牧业蓬勃发展。更多还原

【Abstract】 【Objective】 As the second largest pastoral area in China, Xinjiang possesses rich resources of sheep breeds. Fully understanding the production characteristics and utilization status of these breeds is helpful for farmers to select breeds according to local conditions, thereby releasing production potential and improving breeding efficiency. 【Methods】 The production characteristics, development and utilization status of 13 local sheep breeds in Xinjiang were summarized. 【Results】 In the investigation of crossbreeding utilization of Xinjiang local sheep breeds, it was found that crossbreeding utilization could give full play to heterosis and improve the reproduction, meat production and growth and development performance of offspring. However, a decline in performance had been observed in some crossbred offspring during selective breeding. In response to this trend, specific recommendations were proposed to address challenges in sheep farming in Xinjiang. 【Conclusion】 By fully understanding the advantages and disadvantages of the existing breed resources, and improving the sheep breeding management and technology promotion, theoretical basis was provided for the genetic improvement and production performance enhancement of Xinjiang sheep breeds, thereby fostering the vigorous development of the local livestock industry.更多还原
