【摘要】 测定、分析了两种三元杂交组合（本夏利F₂:公32头,母30头;本夏西F₂:公母各32头）与豫北黄牛初生——24月龄体重与体尺生长发育。结果表明,三元杂交肉牛生长发育快,体重与体尺在各个月龄下均较本地黄牛有较大幅度提高。利用三元杂交进行肉牛生产是一条有效的途径。两种三元杂交组合相比,本夏西F2较本夏利F₂生长发育迅速。更多还原

【Abstract】 The growth and develpment form birth to 24—month—old of Yubie Yellow Cattle and crossbreds from 2 three—way cross(Indigcneous breed×Charolais×Limousin and Indigeneous breed×Charolais×Simmental) was determined and analyzed. Results showed that, the body weight and measurements of ternary hybrids of different ages were greatly increased compared with the indigeneous cattle of the same age. It was an efficient way to use three—way—cross for beef production. As compared between the 2 three—way—cross,crossbreds of Indigeneous breed×Charolais×Simmental was better than those of Indigeneous breed×Charolais×Limousin based on growth and development.更多还原
