摘要
[目的]测量甘南牦牛二元、三元杂交后代周岁内生长发育情况,分析杂交利用方向。[方法]根据牧区草原畜牧业季节性特点,测量了二元、三元杂交后代初生(0月龄)、8月龄和12月龄体尺体重,对比分析不同杂交组合在不同生长阶段的生长发育情况。[结果]不论是二元杂交还是三元杂交,杂交后代均表现出良好的杂交优势,优良品种杂交后代生长发育极显著优于本地品种;安格斯尕力巴牛在8月龄,娟犏牛在12月龄体重达到100 kg以上,可为高原犊牛肉的生产提供优质牛源。
[Objective]To measure the growth and development of the offspring of Gannan yak binary and ternary hybrids within one-year old age,and to analyze the direction of hybridization.[Method]According to the seasonal characteristics of grassland animal husbandry in pastoral areas,the body size and body weight of the offspring of binary and ternary hybrids at birth(0-month age),8-month-old and 12-month-old were measured,and the growth and development of different hybrid combinations at different growth stages were compared and analyzed.[Result]Whether it was binary hybrid or ternary hybrid,the hybrid progeny showed good hybrid vigor,and the growth and development of the hybrid progeny of the excellent breed were significantly better than that of the local breed.Angus garyba cattle at the age of 8 months and Juan Pien cattle at the age of 12 months weigh more than 100 kg,which could provide a high-quality cattle source for the production of plateau calf beef.
