摘要
正确识别母猪正常发情是获得母猪适期配种时间和提高其受胎率的技术关键。目前大部分种猪场识别母猪发情仅依靠人工观察的手段来完成。该文介绍了采用微处理器控制的红外监测系统自动识别母猪的发情。详述了该系统的结构设计 ,包括红外传感与检测电路的设计 ,微处理器的红外信号采集与存储电路的设计等 ,以及用于识别母猪发情的应用原理。该系统在经过种猪场现场测试 ,分析其试验结果后表明 :红外监测系统识别母猪正常发情的准确率达到 80 %以上 。
Accurate recognition of sow oestrus is the key technique for identifying the optimal mating time and improving insemination. But on pig farms it is most often done by the observation of workers. In this paper a microprocessor controlling infra-red detecting system were successfully developed and used to recognize the oestrus of sow. This system comprised infra-red sensor and detecting circuit, microprocessor sampling and storage circuit for infra-red signal and other electronic circuits. The working principle of this system for recognizing was also illustrated. Case study results of the system on a pig farm in Belgium showed that the recognition validation for sow oestrus was above 80%, and the system could be used to reduce effectively the non-productive days of sow and the farm labor cost.
