摘要
人工授精是提高畜产动物生产率的重要工具,猪精液冷冻保存技术已成为当前的研究焦点,冷冻保存后的猪精液品质优劣判断,是依据样本中精子的数量与活力。为在农场工作环境中快速可靠地检测猪精液品质,文中设计了一款以石英晶体微天平和通用频数转换器(UFDC-1)为核心的低成本、可重复使用的精液样本筛选系统。对于同一样本,通过使用文中系统与商用频率计分别测量,对比结果表明,文中系统同样适合对精液样本筛选检测,且低成本更低。
Whereas artificial insemination has arguably been the most important management tool leading to im- proved herd productivity, the study has been focused on the technique of cryopreservation of boar semen. A viable eryopreservation semen sample is judged by the total number of spermatozoa （sperm） in the sample and the motility of the sperm. According to the rapid detection of semen quality, a low cost and reusable system for screening semen samples based on the Quartz Crystal Microbalance （QCM） and Universal Frequency to Digital Converter （UFDC-1） is designed. Data is presented that caused by the same porcine semen samples using the system and a commercial frequency counter. The results show that it can offers a low-cost sensor system suitable for screening a semen sample at the point of use on a farm.
