| 摘 要： | 本研究统计分析了部分非遗传因素(胎次、产仔月份及纯繁/杂交)对长白、大白和杜洛克母猪产仔性能(总产仔数、产活仔数及初生窝重)的影响,旨在为后备母猪的选种提供指导。结果表明,2~5胎仔猪的初生窝重较重;其中2、3胎的初生窝重极显著高于头胎及6胎之后的仔猪初生窝重(P<0.01)。3月份总产仔数、产活仔数及初生窝重极显著高于其他月份(P<0.01),且11月份初生窝重显著低于其他月份(P<0.05)。长白纯繁母猪在产活仔数方面极显著优于大白纯繁母猪和长白×大白杂交母猪(P<0.01);在初生窝重方面,大白×长白杂交母猪的初生窝重极显著高于大白纯繁母猪和长白×大白杂交母猪(P<0.01)。第2胎与3~4胎、第3胎与第4胎的总产仔数呈极显著正相关(P<0.01)。综上所述,该猪场母猪3~6胎的产仔性能较好,且以1~4月份的产仔性能为佳;配种方式以长白纯繁和大白×长白杂交为宜;第2胎产仔性能可作为后备母猪选留的重要依据。

| Abstract: | In order to provide guidance for selection of replacement gilts,this study investigated the effect of partial non-genetic factors (parity,birth month and pure/cross-breeding) on the farrowing performance (total number born,number born alive and birth weight) of Landrace,Yorkshire and Duroc sows.The results showed that the birth weight (BW) from 2nd to 5th parities was heavier,and the BW of 2nd and 3rd parities was extremely significantly higher than the 1st and after 6th parities'' (P<0.01).The total number born (TNB),number born alive (NBA) and BW in March were extremely significantly higher than other months (P<0.01),and the BW in November was significantly lighter than other months (P<0.05).The NBA of pure-breeding Landrace was extremely significantly higher than pure-breeding Yorkshire and Landrace×Yorkshire (P<0.01).The BW of Yorkshire×Landrace was extremely significantly higher than pure-breeding Yorkshire and Landrace×Yorkshire (P<0.01).There was extremely significant positive correlated with 2nd and 3rd to 4th parities in TNB,and so was 3rd and 4th parities (P<0.01).In conclusion,the farrowing performance of 3rd to 6th parities and January to April were the best;Pure-breeding Landrace and Landrace×Yorkshire were the advantageous ways of hybridization;The farrowing performance of 2nd parity could be regarded as an important basis for replacement gilts selection. |
