摘 要:研究在农户舍饲养条件下测定并对比研究了皮西黄、德西黄三元杂交牛及西黄二元杂交公牛各6头4月龄、6月龄、12月龄和18月龄的生长发育指标。结果表明:三元杂交牛18月龄活重达400kg以上,比二元杂交牛提高14.3%~20.4%;体高提高5.3%~10.8%,体斜长提高13.4%~16.7%,胸围提高19.2%~22.4%,管围提高6.5%~17.1%。三元杂交牛其它各年龄段比二元杂交牛体尺、体重均有大幅度的增长,故以上两种杂交组合是适宜当地发展肉牛生产的较佳杂交组合。The perfamance of Piemonte × Simmental × native Yellow, Germany Yellow × Simmental × native Yellow and Simmental× native Yellow cattle were measured. In each line, the growth and development index at 4 month, 6 month, 12 month and 18 month of 6 bulls were determined. The results indicated that three-way cross cattle had a 400 kg live weight at 18 month, which was 14.3%-20.4% higher than that of two-way cross cattle. The withers height, body length, heart girth and circumferance of cannon bone of three-way cross cattle at 18 month were5.3%-10.8%, 13. 4%-16. 7%, 19. 2%-22. 4% and 6.5%-17.1% higher than that of two-way cross cattle, respectively. The body weight and body sizes of three-way cross cattle at other age were also significantly than that of two-way cross cattle. Thus, Piemonte× Simmental × native Yellow, Germany Yellow × Simmental × native Yellow Combinations were useful for local beef cattle production.
