#194 - Selenium supplementation in pig diets:myths and truths - Dr. Darlene Bloxham
Over the last decades, research has shown that selenium plays a critical role in the organism of pigs, especially when the animals are facing stressful events such as weaning, farrowing, and heat stress. However, there are still some misunderstandings about the benefits of selenium and its proper usage, since high levels of the substance in diets can lead to toxicity. In this episode, I have a great conversation with Dr. Darlene Bloxham, a specialist on the subject. She digs into the main questions that arise when it comes to selenium supplementation, including the main differences between selenium sources, the limitations levels, and the ways to supplement it in different production phases, among others. "Selenium is more effective when supplemented before stress. When you supplement it during stress, it does not accumulate in tissues as rapidly as it could otherwise." - Dr. Darlene Bloxham What youโll learn: (00:00) Highlight (01:50) Introduction (03:56) The history of selenium in pig diets (09:20) Differences among sources of selenium (11:55) Mulberry heart disease and selenium deficiency (14:50) Limiting levels of selenium (19:38) Evaluating total selenium levels in the feed (22:32) Supplementing selenium in different phases (25:11) Key messages (26:01) Three final questions Meet the guest:ย Dr. Darlene Bloxham Experience: Current: Nutritionist at Adisseo Background: Ph.D., Animal Nutrition (The University of Georgia) M.Sc, Animal Sciences (The University of Georgia) B.Sc., Animal Nutrition (Ohio State University) Connect with the guest! ๐๐ถ๐๐๐ฒ๐ป ๐ผ๐ป ๐๐ฝ๐ฝ๐น๐ฒ ๐ฃ๐ผ๐ฑ๐ฐ๐ฎ๐๐๐, ๐ฆ๐ฝ๐ผ๐๐ถ๐ณ๐ ๐ผ๐ฟ ๐ฎ๐ป๐ ๐บ๐ฎ๐ท๐ผ๐ฟ ๐ฝ๐น๐ฎ๐๐ณ๐ผ๐ฟ๐บ.
