| 摘 要： | 本研究利用SPSS软件中的方差分析等模块分析了年份、季节、胎次、性别和杂交方式等因素对杂交猪繁殖性能的影响。结果表明,年份对产活仔数和断奶仔猪数有极显著影响(P＜0.01),而对总产仔数无显著影响(P＞0.05)。季节对产活仔数和断奶仔猪数有极显著影响(P＜0.01),对总产仔数有显著影响(P＜0.05)。胎次对断奶仔猪数和初生重有极显著影响(P＜0.01),对产活仔数和出生窝重有显著影响(P＜0.05)。公猪的初生重显著大于母猪的初生重(P＜0.05)。杂交方式对总产仔数、产活仔数、断奶仔猪数、出生窝重和初生重均无显著影响(P＞0.05)。

| Abstract: | In this study, analysis of variance models of SPSS software were used to analyze the effect of different factors such as year, season, parity, birth, and cross mode on crossbred pigs reproductive performance. The following results showed that year gave a significant effect on numbers of piglets born alive and numbers of piglets at weaning (P＜0.01), but no significant effect on numbers of total-piglets (P＞0.05). Season gave a significant effect on numbers of piglets born alive and numbers of piglets at weaning(P＜0.01), and a significant effect on numbers of total-piglets(P＜0.05). Parity gave a significant effect on numbers of piglets at weaning and birth weight(P＜0.01), and gave a significant effect on numbers of piglets born alive and birth litter weight (P＜0.05). Birth weight of hog was significant higher that of sow (P＜0.05). Cross mode gave no significant effect on numbers of total-piglets,numbers of piglets born alive,numbers of piglets an weaning,birth litter weight and birth weight(P＞0.05). |
