【摘要】 通过调查2014年藁城华泽牧业咖啡貂、白貂和黑貂1295只母貂的产仔生产记录,分析不同配种方案、不同品种水貂的产仔数以及母貂的妊娠期,发现咖啡貂产仔性能最高(6.95~7.46只),其次为白貂(5.70~6.16只),黑貂产仔性能最差(5.23~5.76只);配种次数增加,水貂产仔数增加(配种1、2和3次产仔数依次为5.22~5.91,5.86~6.16和6.67~7.35只);水貂妊娠期依次为咖啡貂(50d)>白貂(48d)>黑貂(46~47d);49%的水貂集中在4月26~29日产仔,95%的水貂在5月4日前完成产仔。水貂配种期内,把握发情旺期,采取连续复配多次的配种方案可以提高母貂的产仔数。更多还原
