Abstract

The application of artificial insemination in donkeys must be based on a knowledge of breeding soundness, while other reproductive physiology of the donkey including testicular morphometric parameters and sperm production is scanty in literature. This study sought to assess the testicular morphometry and epididymal sperm qualities of donkeys in Bolgatanga and to determine the effect of season on spermatogenesis and epididymal sperm parameters. Twelve sexually mature donkeys, aging 10 to 15 years old, had their testes and epididymis surgically harvested immediately after slaughter, semen parameters were assessed thereafter and testicular volume calculated. Epididymal sperm was harvested by retrograde flushing technique and sperm parameters were obtained. This study showed no significant difference (p-value >0.05) between the length, width and volume of the left and right testes, and that the rainy season showed greater values in seminiferous tubule diameter, epithelial height, and luminal diameter. The study revealed that donkeys showed a greater level of spermatogenesis in the rainy season compared to the dry season, indicating that donkeys are seasonal breeders.

加纳博尔加丹加驴的睾丸形态和附睾精子质量

驴人工授精的应用必须建立在对繁殖健全性的了解的基础上，而驴的其他生殖生理，包括睾丸形态参数和精子生成，在文献中还很少见。本研究试图评估博尔加坦加驴的睾丸形态和附睾精子质量，并确定季节对精子发生和附睾精子参数的影响。12 头性成熟的驴（年龄在 10 到 15 岁之间）在屠宰后立即通过手术采集了睾丸和附睾，随后评估了精液参数并计算了睾丸体积。采用逆行冲洗技术采集附睾精子，并获得精子参数。研究表明，左右睾丸的长度、宽度和体积没有明显差异（P 值大于 0.05），雨季的曲细精管直径、上皮高度和管腔直径的数值更大。研究表明，与旱季相比，驴在雨季的精子发生水平更高，这表明驴是季节性繁殖动物。

期刊介绍： El European Journal of Anatomy es continuación de la revista “Anales de Anatomía”, publicada en español desde 1952 a 1993. Tras unos años de interrupción debido fundamentalmente a problemas económicos para su mantenimiento, la Sociedad Anatómica Española quiso dar un nuevo impulso a dicha publicación, por lo que fue sustituido su título por el actual, además de ser publicada íntegramente en inglés para procurar así una mayor difusión fuera de nuestras fronteras. Este nuevo periodo se inició en 1996 completándose el primer volumen durante el año 1997.
