This experiment tested the hypothesis that frequent collection of semen from emus would increase the total output of semen and spermatozoa over less frequent collection. Semen was collected from trained male emus using an artificial cloaca. In Experiment 1, semen was collected from males every 4th d (96-h interval), every 2nd d (48-h interval), and every day (24-h interval) for 16 d. In Experiment 2, semen was collected daily (24-h interval), twice daily (6-h interval), and three times per day (3-h interval) over 6 d. Twice-daily collections yielded twice as much volume and number of spermatozoa than daily collections. Collecting semen three times per day did not yield extra semen, as it adversely affected the libido of males. Twice-daily collections appears to yield the optimum output over the 6 d of this experiment, but longer periods of collection need to be studied.
相较于不频繁采集，频繁采集鸸鹋精液会增加精液和精子的总产量。使用人工泄殖腔从经过训练的雄性鸸鹋采集精液。在实验1中，每隔4天（96小时间隔）、每隔2天（48小时间隔）和每天（24小时间隔）从雄性鸸鹋采集精液，持续16天。在实验2中，在6天内每天（24小时间隔）、每天两次（6小时间隔）和每天三次（3小时间隔）采集精液。每天采集两次所获得的精液量和精子数量是每天采集一次的两倍。每天采集三次并未产生额外的精液，因为这对雄性鸸鹋的性欲有不利影响。在本实验的6天期间，每天采集两次似乎能产生最佳产量，但需要研究更长的采集周期。
