摘　　要：该研究采用同质选配的方法,选择初生公羔37只,经过初生、2月龄(断奶)、6月龄和周岁的系统选育,获得优秀种公羊11只,平均体重66.13 kg,体高78.38 cm,体长87.25 cm,胸围109.25 cm,其体型外貌、生长性能、体尺测定等指标均超过特藏寒杂交绵羊种公羊选育标准要求,为特藏寒杂交绵羊持续选育提供重要依据。In this study,37 newborn male lambs were selected by the method of homogeneity selection,and 11 excellent breed RAMS were obtained through systematic breeding at birth,2 months old(weaning),6 months old and 1 year old.The average weight was 66.13 kg,the body height was 78.38 cm,the body length was 87.25 cm,and the chest circumference was 109.25 cm.Its body shape,growth performance,body size measurement and other indicators exceeded the breeding standard requirements of Tezanghan crossbred sheep,which provided an important basis for future breeding of Tezanghan crossbred sheep.
