摘要: 晋汾白猪是以马身猪、太湖猪、长白猪和大白猪为育种素材,通过复杂杂交育种和标记辅助选择而育成的一个瘦肉型猪新品种。试验对6个世代后备猪生长发育性状的选育结果进行分析,结果发现,后备公猪6世代与0世代相比,初生重提高了0.13 kg,断奶重提高了0.56 kg,70日龄体重提高了1.69 kg,180日龄体重提高了12.46 kg,70~180日龄平均日增重提高了107.00 g,差异均显著(P<0.05);后备母猪180日龄体重6世代比0世代显著提高了10.84 kg(P<0.05)。后备公猪和母猪4、5世代的初生重、断奶重、180日龄体重和70~180日龄日增重均显著高于0世代(P<0.05)。选育结果表明,晋汾白猪的生长发育性状取得了较大的遗传进展。

Abstract: Jinfen White pig was a new lean-type variety by crossing Mashen pig, Taihu pig, Landrace, Yorkshire pig and selecting by means of combining the marker assisted selection with systematic breeding. The selection of growth and development of six generations showed that compared with the base population, body weight at birth, body weight at weaning, body weight at 70-day-old, body weight at 180-day-old, and average daily gain during the period of 70 to 180 d of boars at the sixth generation were remarkably increased by 0.13 kg, 0.56 kg, 1.69 kg, 12.46 kg and 107.00 g, respectively (P<0.05). Compared with the base population, body weight at 180-day-old of gilts at the sixth generation was significantly increased by 10.84 kg (P<0.05). Body weight at birth, body weight at weaning, body weight at 180-day-old and average daily gain during the period of 70 to 180 d of gilts and boars at the fourth and fifth generation were significantly higher than these traits of the base population, respectively (P<0.05). It indicated that growth and development performances of Jinfen White pig had made significant genetic progress.

Key words: Jinfen White pig; growth and development; genetic progress
