Review of Research Progress in Intelligent Identification Technology and Equip-ment for Sows Estrus
Intelligent diagnosis of estrus in pigs was an important technical means to improve reproductive efficiency,precisely control breeding programs and improve breeding management efficiency.In order to systematically understand the current status,application and problems of sows estrus intelligent diagnosis technology.Firstly,this paper introduced the traditional diagnosis methods of sows estrus and summarized the research progress of sows estrus intelligent diagnosis technology and equipment at home and abroad.And then,it systematically analyzed the classifications,advantages and disadvantages of sows estrus intelligent diagnosis technology,in-cluding the technology based on image/video recognition,sound recognition,sensor perception,etc.Finally,an outlook for the devel-opment trend of sows estrus intelligent diagnosis technology was proposed,with a view to providing technical references for pig intelli-gent breeding and the healthy and sustainable development of the animal husbandry industry.
