摘要
试验以南阳黑猪与大白猪为研究对象,分析其活体背膘厚差异。结果表明,南阳黑猪与大白猪3点校正达100 kg活体背膘厚平均值分别为(34.38±0.57)mm、(11.69±0.28)mm,南阳黑猪3点校正达100 kg活体背膘厚平均值极显著高于大白猪(P<0.01),在品种的筛选上南阳黑猪比大白猪更占优势。
In order to study the difference of fat traits between imported pig breeds and Chinese local pig breeds, and to speed up the progress of genetic improvement of Nanyang black pig and breed pigs with good quality, we analyzed the vivo backfat thickness difference between Nanyang black pigs and Large white pig. The results showed that the average value of 100 kg body weight corrected back fat thickness of Nanyang black pig and Large white pig is （34.38±0.57） mm and （11.69±0.28） mm respectively, vivo backfat thickness of Nanyang black pig was significantly higher than that of Large white pig （P〈0.01）, in the selection of varieties is more dominant than white black pig. Nanyang black pig has an advantage over Large white pig in selection of pig varieties.
