| 摘 要： | 本试验较详细地研究了正在培育的甘肃黑猪甘农系群与苏联大白猪及其正反杂交猪的肥育性能。证实甘农系群猪的肥育性能接近于苏大白猪。二者正反杂交后的杂种均有一定的杂种优势,获得较好的经济效益,而以反交方式增加效益最显著。正反杂交均可应用于商品肉猪生产。

Studies on Hog Fattening Properties and Economic Benefits of Gannong Strain,Large White of USSR and Their Positive and Negative Cross-Breds |
| |
| Abstract: | This experiment studied Gannong Strain (developed from black pig of Gansu)and the Large White of USSR, and their fattening properties after their positive and negative cross- breeding. It has proved that the fattening properties of Gannong strain and the Large White of USSR are very alike. The positive and negative cross of the two strains provides good heterosis, thus giving good economic benefit. But it can, be increased remarkably by means of negetive crossing. The positive and negetive crossing can be applied in commercial hog production. |
