| 摘 要： | ZFY系是利用国外引进的法系大约克猪为育种素材,采取常规继代选育与分子标记相结合的育种技术,经过5个世代选育,培育出的优质肉猪配套系专门化父本新品系。五世代种猪体重达100 kg的日龄比一世代缩短11.82天、每增重1 kg少耗料0.23 kg,瘦肉率提高1.75个百分点。无应激敏感基因的阳性个体,肉品质良好,遗传性能稳定。

| Abstract: | ZFY line is a new specialized sire line of high-quality pig synthetic lines bred on the base of France Yorkshire.It was formed by the combined breeding ways of the conventional herd breeding and molecular assisted markers through 5 generations selection.Compared with one generation,the days of the pigs arriving 100 kg bodyweight,the consumed food per kilogram weight and the lean meat percentage were less 11.82 days,0.23 kg and 1.75 percentage point,respectively.The ZFY line pigs have high-quality meat and stable inheritance.There is not Haln gene in the population. |
