摘要: 【目的】对我国11个省市的34个大型猪场的主要生产水平进行抽样调查。【方法】对不同区域间进行对比分析,对不同地理位置分布的猪场进行聚类分析。【结果】当前我国规模化猪场的总体母猪繁殖性能与生产水平较好,并且南北方各规模化猪场的母猪繁殖性能与生产水平没有显著差异。但是,不同规模猪场间存在较大差异,大量规模化猪场的生产水平都还有很大的提升空间。并且,同一集团公司内部的不同猪场间的生产水平差异较大。【结论】地理环境不会对各猪场的母猪总体繁殖性能与生产水平造成显著影响,但我国部分种猪场以及同一公司内部不同场间的母猪繁殖性能与生产水平存在显著差距,这在一定程度上反应了管理水平的差异,故存在较大的改进空间。

Abstract: 【Objective】 This study was aimed to investigate the main production level of 34 large pig farms in 11 provinces and municipalities in China. 【Method】 A comparative analysis was conducted among different regions, and a cluster analysis was conducted for pig farms with different geographical locations. 【Result】 At present, the overall sow reproductive performance and production level of large-scale pig farms in China are good, and there is no significant difference in reproductive performance and production level of sows in large-scale pig farms in the north and south. However, there are large differences between pig farms of different scales, and there is still much room for improvement in the production level of a large number of large-scale pig farms. Moreover, the production levels of different pig farms varies within the same group company. 【Conclusion】 Geographical environment has limited impact on the overall reproductive performance and production level of pig farms, but there is a significant gap between certain pig farms in China and even within one company, indicating the management level varies from pig farms and there is still much room for improvement.

Key words: large scale pig farm, cluster analysis, production level
