摘　　要：“凉黑一号”猪本品种选育研究发现,“凉黑一号”猪发情症状表现稳定,是一个早熟猪种。产活仔数、初生窝重、断奶窝重指标随着选育代次增加呈波动性提高,选育进展明显,其中G3代总产仔数从10.34头提高到10.86头,初生窝重从11.24 kg提高到11.96 kg,28日龄断奶窝重从54.64 kg提高到58.13 kg,可以作为本品种选育的选择指标。产活仔数、初生个体重和断奶存活率等3个指标选育进展不明显,建议不作为本品种选育提高的选择指标参与选育工作。The breeding of“Lianghei No.1”pig showed that the estrus symptom of“Lianghei No.1”pig was stable and it was an early maturing pig breed.The number of live litter,birth litter weight and weanling litter weight fluctuated with the increase of breeding generations,and the breeding progress was obvious.The total number of litter born in G3 generation increased from 10.34 to 10.86,and the birth litter weight increased from 11.24 kg to 11.96 kg,the litter weight of weaning at 28-day-old was increased from 54.64 kg to 58.13 kg,which could be used as the selection index of this variety.The breeding progress of the three indexes of litter size,birth weight and weaning survival rate was not obvious.It was suggested that the three indexes should not be used in the breeding.
