[目的] 探讨半番鸭生产中的人工授精技术.[方法] 选用公番鸭和樱桃谷母鸭为试验材料,采用按摩采精法和翻肛输精法进行人工授精试验,探讨输精量、输精间隔时间、输精时间以及稀释液对受精率的影响.[结果] 公番鸭和樱桃谷母鸭自然交配受精率很低,平均受精率为39.58%,人工授精受精率可达74.79%.用磷酸缓冲液和Lake's液稀释精液的受精率比较高,分别为75.24%和75.16%,与原精液组受精率(74.10%)差异不显著.精液稀释后在5 ℃保存24 h后输精,其受精率均较低,分别为23.76%和34.33%.[结论] 在半番鸭生产中,采用人工授精技术可降低精液使用量和提高受精率.%[Objective] To explore artificial insemination technique of mule duck. [Method] Male Muscovy duck and female Cherry Valley duck were selected to conduct artificial insemination. Semens of male Muscovy duck were collected with massage method and inseminated the female Cherry Valley duck with vagina-insemination method. Effects of volume of semen, insemination interval, insemination time and diluent on fertilization rate were studied in series of experiments. [ Result] The average fertilization rate was only 39.58% by natural mating between male Muscovy duck and female Cherry Valley duck, while the average fertilization rate increased to 74.79% by artificial insemination. There were no significant difference between fresh semen and diluted semens by phosphate and Lake's buffer. The fertilization rate of diluted semens by phosphate and Lake's buffer were 75.24% and 75.16% respectively, and the fertilization rate of fresh semen was 74.10%. The semen was diluted by phosphate and Lake's buffer, then stored at 5 ℃ for 24 h. The average fertilization rate of these two diluted semen decreased to 23.76% and 34.33% respectively. [Conclusion] Artificial insemination technology can reduce semen volume and increase the fertilization rate in Mule duck production.
