皖南花猪不同头型母猪繁殖性能比较研究

Comparative study on reproductive performance of different head type sows in south Anhui pigs

皖南花猪按头型可分为狮子头型、马脸型和桩头型,为研究皖南花猪母猪不同头型母猪间的繁殖性能差异,研究通过整理安徽省皖南花猪保种场以往数据,现场记录等方法,统计皖南花猪不同头型经产母猪(370窝)的窝产仔数、窝产活仔数、初生窝重、35日龄窝断奶仔猪数和35日龄断奶窝重等繁殖性能指标,并进行比较分析。结果如下:皖南花猪马脸型母猪窝产仔数、窝产活仔数、仔猪初生窝重、35日龄断奶仔猪数、35日龄断奶窝重均显著高于狮子头型及桩头型母猪(P<0.05);皖南花猪桩头型母猪在窝产仔数、窝产活仔数、仔猪初生窝重等繁殖性能上优于狮子头型母猪,但在35日龄断奶窝重这一指标中低于狮子头型母猪。研究表明皖南花猪马脸型母猪繁殖性能与狮子头型、桩头型母猪相比更为优异,为皖南花猪种质资源保护与开发利用提供了一定的参考依据。

Wannanhua pigs can be divided into three different types(Shizitou,Malian,Zhuangtou).Our study collected reproductive performance data(included the total number of litter,the number born alive,litter weight of birth,number of piglets weaned at 35 days and litter weight at 35 days)from Wannanhua pigs preservation farm of Anhui province to compare the difference of reproductive performance between different head types sows.From the research results,compared with Shizitou and Zhuangtou,Malian sows of Wannanhua pig showed higher total number of litter,the number born alive,litter weight of birth,number of piglets weaned at 35 days and litter weight at 35 days(P<0.05);Zhuangtou sows of Wannanhua pig have higher total number of litter,total number of litter,the number born alive and litter weight of birth than Shizitou sows,but have lower litter weight at 35 days than Shizitou sows.In summary,Malian sows of Wannanhua pigs have greater reproductive performance than Shizitou and Zhuangtou sows,our results provided reference for conservation and exploiting of Wannanhua pigs.
