摘　　要：[目的]为了提高云南黄牛的生产性能,优选主要的杂交改良父本,开展云南黄牛杂交改良。[方法]用西门塔尔牛、短角牛、安格斯牛、海福特牛等分别与云南黄牛母本杂交,测定不同杂交组合后代初生、6月龄、12月龄、24月龄的体重体尺。[结果]云南黄牛经过杂交改良后,改良效果良好,杂交后代对云南高原的气候条件适应性良好。在农村饲养条件下,西×云杂一代牛初生重平均为24.57kg,6月龄体重平均为135.83kg,12月龄体重平均为196.21kg,24月龄体重平均为344.24kg,分别比本地黄牛提高74.13%,59.20%,56.53%和78.10%。短×云杂交一代牛初生重平均为22.28kg,6月龄体重平均为117.20kg,12月龄体重平均为193.56kg,24月龄体重平均为314.86kg,分别比本地黄牛提高57.90%,38.10%,54.21%和62.90%;安×云杂交一代牛犊牛初生重平均为21.21kg,6月龄体重平均为134.34kg,12月龄体重平均为196.18kg,24月龄体重平均为268.45kg,分别比本地黄牛提高50.32%,57.45%,56.51%和38.89%;海×云杂交一代牛初生重平均为22.78kg,6月龄体重平均为124.97kg,12月龄体重平均为190.52kg,24月龄体重平均为289.50kg,分别比本地黄牛提高61.45%,46.47%,51.99%和49.78%。[结论]西×云杂一代牛、短×云杂交一代牛、安×云杂交一代牛和海×云杂交一代牛生产性能显著提高,效益明显。[Objective]In order to improve the production performance of Yunnan cattle, the screening on crossbreeding and improvement paternal were carried by the imported breeds crossbreeding of Yunnan cattle in Yunnan. [Method] Angus and Hereford of qual born, 6 months 12 months Yunnan female cattle was mated with the imported Simmental, Shorthorn, ity beef breeds from abroad, and the body weight and size of hybrids at new- and 24 months old were measured. [Result]The adaptability of crossbreeding offspring （F1） were very well. The results showed that the body weight of F1 with Simmental or Shorthorn or Angus or Hereford at birth was 24.57 kg,22. kg; at 6 month-old was 135.83 kg, 117.20 kg, 134.34 kg and 124.97 kg; at 12 193.56 kg, 196.18 kg and 190.52 kg; at 24 month-old was 344.24 kg,314.86 crossbreds of yunnan cattle 28 kg,21.21 kg and 22.87 month-old was 196.21 kg, kg, 268.45 kg and 289.50 kg ; The body weight of yunnan cattle at birth was 14.11 kg^at 6 month-old was 85.32 kg; at 12 month old was 125.35 kg; at 24 month-old was 193. 28 kg. [ConclusionlThe production performance of cross breeding offspring and the improvement effect were significant.
