Abstract

Over three breeding seasons on a farm in Poland, semen was collected from 11 ostriches using the dummy and the teaser method to study the effects of the method of collection, male age, month in the breeding season, and daily collection frequency on ejaculate characteristics. 2. A total of 259 ejaculates were collected, with an average volume of 1·28 ± 0·6 (±SEM) ml. Sperm concentration was 3·34 ± 0·08 × 10(9)/ml, the total number of spermatozoa 4·32 ± 0·22 × 10(9), and motility 4·56 ± 0·04. 3. There was no difference in ejaculates collected by the dummy and teaser methods, but the between-individual variation was considerable. Ejaculate characteristics increased with male age and varied between months, with little evidence for seasonal decline. Daily collections for 10 days did not affect sperm output. 4. The results open up avenues for further research on development of a viable protocol for artificial insemination in ostriches and efficient semen storage. 5. The between-male variation suggests that the ejaculate output could be maximized through selection.

摘要

在波兰的一个农场进行了三个繁殖季节的研究，使用假阴道和诱情剂的方法从 11 只鸵鸟中采集精液，以研究采集方法、雄性年龄、繁殖季节的月份和每日采集频率对精液特征的影响。
共采集了 259 份精液，平均体积为 1.28±0.6（±SEM）ml。精子浓度为 3.34±0.08×10(9)/ml，精子总数为 4.32±0.22×10(9)，运动性为 4.56±0.04。
假阴道和诱情剂采集的精液没有差异，但个体间差异很大。精液特征随着雄性年龄的增加而增加，并且在月份之间存在差异，几乎没有季节性下降的证据。连续 10 天的每日采集不会影响精子产量。
研究结果为进一步研究鸵鸟人工授精的可行方案和有效精液储存开辟了途径。
雄性间的变异表明，通过选择可以最大限度地提高精液产量。
