摘要 滇陆猪是我国自主培育的含太湖猪血统的新品种猪。为了解滇陆猪在农户中扩繁饲养的效果,为今后示范推广工作提供参考依据。本研究通过实地走访调查,拍摄云南省陆良县8个滇陆猪扩繁场的繁殖记录,对扩繁母猪产仔数、产活仔数、死胎数、木乃伊数等进行系统整理和分析,对影响扩繁母猪产仔数的影响因素进行分析。结果表明,滇陆母猪的总产仔数和产活仔数分别比二元杂交母猪(长大、大长)多2.0头和2.3头(P<0.05);场次和胎次对滇陆猪总产仔数、产活仔数影响极显著(P<0.01),场次对死胎数影响显著(P<0.05),场次和胎次对木乃伊数影响显著(P<0.05)。总体来说,农户扩繁饲养的滇陆猪表现出了较优的产仔性能,扩繁场的疾病防控工作做得较好,但不同猪场之间的饲养管理水平差距大。研究调查分析了滇陆猪产仔性能及影响因素,为其推广利用提供重要依据。
