摘要
为了研究皮德蒙牛对本地改良母牛的改良效果,测定了皮黑F1,皮西F1和皮犏F1、代牛初生、30日龄和90日龄的体重和多项体尺指标,结果表明,皮西F1组的各项被检指标均显著高于其他两种杂交组合后代的指标。
The indices of body liveweight and size of F1 crossbred of Holstein × Piedmont, Siromental × Piedmont, Pienniu × Piedmont at the birth and at the age of 30 and 90 days were determined to study the improving effect of Piedmont on native improved cattle. The results showed that all the indices examined of F1 crossbred of Simrnental x Piedmont were significantly higher than those of Holstein x Piedmont and Piedmont × Piedmont.
