The common marmoset (Callithrix jacchus) is of interest for reproductive studies because of their high and variable fertility in captivity. However, to understand this variability, much basic information still needs to be gathered. This study is the first to characterize marmoset semen comparing a German and a Brazilian colony.
All animals were weighted, and semen samples were collected by penile vibratory stimulation and analyzed according to standard criteria.
The German animals had a higher mean and maximum weight than the Brazilian. Further, sperm concentration tended to be higher with heavier animals in the German population, but not in the Brazilian. Additionally, major defects tended to be more frequent with higher weight but also only in German sample. In spite of these differences, the total range and variability in sperm concentration were similar in both populations, suggesting that this is characteristic for the species.
普通狨猴(Callithrix jacchus)因其在圈养环境中具有较高且多变的繁殖力而成为生殖研究的关注对象。然而,为了解这种变异性,仍需收集许多基础信息。本研究首次对来自德国和巴西的两个狨猴群体的精液进行了特征描述。
对所有动物进行称重,并通过阴茎振动刺激采集精液样本,然后根据标准标准进行分析。
德国的动物平均体重和最大体重均高于巴西的动物。此外,在德国群体中,体重较重的动物精子浓度往往更高,但在巴西群体中并非如此。此外(精液)主要缺陷在体重较高的情况下往往更频繁出现,但也仅在德国样本中如此。尽管存在这些差异,但两个群体中精子浓度的总体范围和变异性相似,这表明这是该物种的特征。
