摘　　要：[目的]研究张掖近20年来选育的肉牛新品种各世代公、母牛繁殖性能,为种群扩繁和高效推广利用提供科学依据。[方法]利用张掖肉牛新品种选育技术资料,对4个世代的选育张掖肉牛配种、产犊记录进行分类汇总、统计分析,数据用Excel 2010进行初步整理。[结果]张掖肉牛母牛初配年龄为15~18月龄,初配体重为380~420 kg,产犊月龄为21~24月龄。横交选育的不同世代母牛表现出较好的繁殖性能,平均犊牛成活率97.9%,繁殖成活率81.74%。[Objective] This article was to study the male and female cattle reproductive performances of various generations from new beef cattle breed in Zhangye in recent 20 years, which would provide scientific basis for population expansion and efficient promotion and utilization. [Methods] The mating and calving records of four generations of Zhangye beef cattle were sorted out, classified, and statistically analyzed by using the breeding data of Zhangye new breed beef cattle. The data were preliminarily sorted out by Excel 2010. [Results] The initial mating age of Zhangye beef cattle was 15~18 months, the initial mating weight was 380~420 kg, and the calving age was 21~24 months. The cows of different generations selected by cross breeding showed good reproductive performance, with an average calf survival rate of 97.9% and a reproductive survival rate of 81.74%.
