利延杂交F_1与延边黄牛生长性能比较研究

Study on growth performance of Yanbian Yellow Cattle and F_1 of Limousin×Yanbian Yellow Cattle

以利木赞牛为父本,延边黄牛为母本,得到利延杂交F1牛,将其生长性能与役肉兼用型延边黄牛进行对比研究的结果表明,从6～24月龄的体重、各项体尺指标,利延杂交F1牛均极显著高于延边黄牛,说明利延杂交F1牛的生长发育速度比延边黄牛快,且适应性较强.

The growth performace of F1 of Limousin × Yanbian Yellow Cattle and Yanbian Yellow Cattle was compared. The results .showed that the body weight and body sizes of F1 of L × Y in 6--24 months age were all significantly higher than Yanbian Yellow Cattle, which proved the growth performance of F1 of （L × Y） was better than Yanbian Yellow Cattle. Besides, the adapt ability of F1 of L × Y to new surroundings was one of their good qualities.
