摘　　要：在相同的舍饲草料条件下,对宁夏地区目前存留和仍被杂交改良生产利用的萨福克、杜泊、特克赛尔、陶赛特等主要引进品种的杂交利用效果和后裔生产性能表现进行了对比分析。结果表明,这些品种杂交后代普遍表现出生长速度快、饲料报酬高、产肉和繁殖性能好的特点,特别是杜泊品种杂交后裔的产肉和繁殖性能比其他品种杂交后裔的表现更为突出。Under the same barn feeding and grass fodder, the hybrid utilization effects and progeny performance of some main introduced varieties like Suffolk sheep, Dorper sheep, Texel sheep and Dorset sheep which presently existed or have been crossed and improved in Ningxia were compared and analyzed. Results showed that hybrid progenies of the varieties all had features of fast growth rate, high forage reward and good meat production and reproductive performance, especially the meat production and reproductive performance of Dorper sheep＇ hybrid progenies were more obvious than the other varieties.
