A contribution is presented towards stabilizing the sperm production of A. I. bulls under subtropical conditions. The results are outlined of a production experiment on the influence of different sperm collection frequencies on the sperm production as found in 48 insemination bulls of a central bull station in the Syrian Arab Republic in the course of one year. It was found that a rhythm of 2 collections per bull and week provides favourable conditions for a stable and high-level sperm production.
本文旨在为亚热带条件下稳定人工授精公牛的精子生产做出贡献。文中概述了一项生产实验的结果，该实验研究了不同采精频率对精子生产的影响，实验对象是阿拉伯叙利亚共和国一个中央种公牛站的48头授精公牛，为期一年。结果发现，每头公牛每周采精2次的频率能为稳定且高水平的精子生产提供有利条件。
