Managing boar taint: issues, prevention strategies, and detection methods

Abstract

Managing boar taint involves addressing welfare concerns related to castration, understanding the compounds causing the taint, and developing reliable detection methods. Surgical castration of piglets is common but raises welfare issues, prompting calls for alternatives. The European Union has seen slow progress in banning castration without pain relief, with varying national approaches. Boar taint, caused by androstenone and skatole, produces unpleasant odors and flavors in pork. Factors like genetics, age, and rearing conditions affect taint levels. Raising entire males or using immunocastration are the two main alternatives to physical castration, but both come with drawbacks such as welfare concerns and increased costs. Other strategies include feed supplementation, management practices, and genetic approaches. Detecting boar taint is crucial to ensure product quality, but no universal measurement standard exists. Efforts should focus on improving detection methods and processing techniques to reduce taint perception, balancing welfare, production efficiency, and consumer satisfaction. This review synthesizes existing scientific knowledge on boar taint, its prevention, and detection methods, while highlighting innovative strategies and critical research gaps to guide future advancements in sustainable pork production.
