| 摘 要： | 为了研究日粮中添加纳米硒时公羊睾丸发育的影响.试验选用体重、日龄接近的20只波尔山羊公羔羊,随机分为两组,一组日粮中添加0.3 mg/kg的纳米硒(以硒计),另一组饲喂基础日粮,预试2周,试验期每月测量睾丸周径、长度和高度,每组阉割1只公羔,按照常规方法制作石蜡切片,观察睾丸组织结构.结果显示:3月龄时纳米硒组睾丸间质组织增生发育,4月龄时纳米硒组睾丸曲精细管中精原细胞开始发育分化;5月龄时曲精细管中可见大量的精子,而时照组间质组织以及曲精细管发育、精母细胞发育分化较纳米硒组缓慢.试验表明,日粮中添加一定浓度的纳米硒能够促进睾丸间质组织及曲精细管的发育,促进精母细胞的分化.

| Abstract: | An experiment was conducted to study the effect of nano-Se on testicular growth and development in Boer Goat. Total 20 goats were randomly divided into 2 groups, and fed basal diet or supplementation 0.3 mg/kg nano-Se (as Se content). After 2 weeks of pretrial, the testicular length, height and girth were measured every month,and one goat castratsd randomly in each group. One of the testis was made the microscopic section, and the testicular microstructure observed. The results showed that the interstitial ... |
