Experiments were conducted to compare management of ganders and semen collection procedures with respect to semen and sperm yield, and two frequencies of artificial insemination were tested with respect to fertility. Housing ganders in groups, singly, or singly with the introduction of a female just before collection was the rank order of housing system from least to most successful collection of ejaculates. There were no significant differences among types of housing with respect to semen volume, but ejaculates from ganders housed singly had the greatest (P less than .05) spermatozoal concentrations. Ejaculates collected with an artificial vagina were of greater (P less than .05) volume and total spermatozoal yield but not spermatozoal concentration than those collected by aspiration. Interactions between collector and method were observed for spermatozoal traits. Geese inseminated on 2 consecutive days/wk showed greater (P less than .01) fertility than those inseminated once per week. Therefore, collection of semen with an artificial vagina from ganders housed singly, with insemination weekly but on consecutive days, should result in successful reproduction of geese.
进行了实验，以比较公鹅的管理方式和采精程序对精液及精子产量的影响，并测试了两种人工授精频率对受精率的影响。将公鹅成群饲养、单独饲养，或在采精前单独饲养并引入一只母鹅，这三种饲养方式按采精成功率由低到高排序。不同饲养方式下精液体积没有显著差异，但单独饲养的公鹅射出的精液精子浓度最高（P<0.05）。与用吸管采集的精液相比，用人工阴道采集的精液体积更大（P<0.05），总精子产量更高，但精子浓度没有差异。观察到采集者与采集方法之间对精子性状存在交互作用。每周连续两天进行人工授精的鹅比每周授精一次的鹅受精率更高（P<0.01）。因此，从单独饲养的公鹅身上用人工阴道采集精液，每周连续两天进行人工授精，应该能实现鹅的成功繁殖。
