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。By investigating the litter size records of coffee mink, white mink and black mink from Huaze animal farm in Gaocheng in 2014, and analyzing the different breeding schemes, the different kinds of mink litter size and the duration of gestation, it was concluded that the coffee mink had the biggest litter size （6.95-7.46）, followed by white mink （5.70-6.16）, and the black mink,also the lowest （5.23-5.76）. By increasing the times of crossbreeding, the litter size were increased（the litter size of minks receiving 1, 2, and 3 times of cross breeding were 5.22-5.91, 5.86-6. 16 and 6.67-7.35. ）. The duration of gestation was 50 d, 48 d and 46-47 d, respectively for coffee mink, white mink and black mink. 49 % of mink produced from April 26th to 29th and 95 percent of mink finished producing before May 4 th. During the breeding period, breeding continuously in oestrous period can enlarge the litter size of female minks.
