利用地方猪种来选育用于生产优质商品猪的配套系的方法
摘要：
一种利用地方猪种来选育用于生产优质商品猪的配套系的方法。本发明公开了一种生产优质商品猪的配套系选育方法，其包括如下步骤：A)以无氟烷隐性基因皮特兰猪作为配套系的第一父本，以枫泾猪作为配套系的第一母本，杂交获得皮枫杂种猪；B)选取杜洛克猪作为配套系的第二父本，以皮枫杂种猪作为配套系的终端母本，杂交获得优质商品猪。本发明的配套系第一母本经产母猪平均产仔数不低于14头，优质商品猪的生长速度达600g/d以上，瘦肉率达60％以上，料肉比不高于3.5，肌内脂含量高于2.5％，且无PSE肉。
摘要（英）：

The invention discloses a commercial strain method utilizing local pig breeds to breed high-quality commercial pigs, comprising the following steps: A) utilizing a freon-free recessive gene Pietran as a first male parent of the commercial strain and Fengjing pig as a first female parent of the commercial strain, hybriding to obtain a Pietran-Fengjing cross-bred pig; and B) selecting a Duroc as a second male parent of the commercial strain and the Pietran-Fengjing cross-bred pig as a terminal female parent, hybriding to obtain the high-quality commercial pig. The average farrowing number of the first female parent of the commercial strain is not less than 14, the growth rate of the high-quality commercial pig can be up to more than 600 g/d, the lean meat percentage is more than 60%, the feed conversion rate is not more than 3.5, the intramuscular fat content is more than 2.5%, and the high-quality commercial pig has no PSE meat.
