摘　　要：[目的]研究杜洛克猪和环江香猪、隆林猪杂交后代的繁殖性能和生长性能,为优良性状新品系猪的选育工作提供基础依据。[方法]通过杜洛克猪♂×环江香猪♀和杜洛克猪♂×隆林猪♀杂交分别获得杂交后代杜香猪和杜隆猪,测定杜香猪、杜隆猪的体长、体高、胸围、腹围、体重等生长性能,记录母猪窝产仔数、窝产活仔数、初生窝重及其仔猪30日龄断奶头数、30日龄断奶窝重等繁殖性能。[结果]杜香猪和杜隆猪的生长性能和繁殖性能均较优良,杂交后代集中了环江香猪、隆林猪和杜洛克猪的优良性状。[结论]利用广西地方猪种来培育优良性状新品系猪,环江香猪和隆林猪可作为良种的二元杂交母本使用。[Objective]To investigate the reproductive and growth performance of crossbred offsprings between two Guangxi local pig breeds and Duroc Pig,and provide the basis for the breeding of new pig lines with excellent traits.[Method]By means of crossbreeding between Duroc Pig(♂)and Huanjiang mini-pig(♀)or Duroc(♂)and Longlin Pig(♀),Duxiang Pig and Dulong Pig were acquired respectively.The growth performance(such as body length,body height,chest measurement,abdominal circumference)of Duxiang Pig and Dulong Pig were measured,and reproductive performance of hybrid offsprings were recorded,such as the litter size,the number of live births,litter weight at birth,litter size at 30-day weaning,litter weight at 30-day weaning.[Result]The growth performance and reproductive performance of Duxiang Pig and Dulong Pig were excellent,Duxiang Pig and Dulong Pig gathered the fine traits from their parents.[Conclusion]Guangxi local pig breeds could be used to cultivate new pig line with good traits.Huanjiang mini-pig and Longlin Pig could be used as binary hybrid parent of improved breed.
