摘　　要：死胎和木乃伊对猪产活仔数有重要影响,产生死胎和木乃伊的因素有传染性因素和非传染性因素。利用广东省某猪场的繁殖记录,分析了亚热带气候条件下非传染因素对母猪产死胎和木乃伊的影响。结果表明,随胎次增加和怀孕天数减少,死胎出现的概率增加;总产仔数增加,怀孕天数下降,出现死胎和木乃伊的概率上升;分娩月份对死胎和木乃伊出现的概率影响显著,母猪1、2、3、12月份分娩,出现死胎的概率较低,而母猪2、3、5、10、11、12月分娩,出现木乃伊的概率较低。Stillbirth and mummification have a profound negative effect on the number of piglets born alive. Both infectious and noninfectious factors can cause stillbirth and mummification in pigs. The data of a swine farm in Guangdong was used to analyze the effects of noninfectious factors on the probabilities of stillbirth and mummification under subtropical climatic condition. The results showed that higher parity and shorter gestation length could increase the probability of stillbirth, and larger litters were associated with shorter gestation length and higher probabilities of stillbirth and mummification. The parturition season was significantly related the probabilities of stillbirth and mummification; piglets born in January, February, March and December had a lower rate of stillbirth, and those born in February, March, May, October, November and December were less possible to be mummified.
