摘要: 本文研究19头长梅杂种母猪(长白猪×梅山猪)和18头汉梅杂种母猪(汉普夏猪×梅山猪)的繁殖性能。结果表明:长梅和汉梅母猪的发情征兆不及地方猪种明显。长梅和汉梅母猪发情持续期为4天左右,性欲维持2天左右;初配和第二胎发情配种,情期受胎率分别为93.2%和97.l%;头胎和第二胎,窝平产仔数分别为11.9头和14.3头,活产仔数分别为7.6头和13.4头;40日龄断奶窝重分别为58.00kg和103.02kg。梅山二元杂种母猪保持了梅山猪的高繁殖力特点。

Abstract: Reproductive performance of 19 landrace X Mei shan(LM) gilts and sows and 18 Hampshire X Meishan (HM) gilts and sows was studied. The results were as follows: Estrous signs of LM and HM gilts and sows were less obvious than those of the local breeds. The estrus duration of the LM and HM female pigs was about 4 days and their libido lasted about 2 days. The conception rate of the gilts was 91.2% and the sows 97.1%. For the gilts and sows, the litter size was 11.9 and 14.3 respectively, and the alive piglets per litter at birth,were 7.6 and 18.4 respectively, and 40-day weaning weight was 58.00kg and 103.02kg respectively. The crossbreds were also exceptionally prolificacy as thire female parent-Meishan pigs.
