Organic selenium (Se) has gained recognition in poultry nutrition as a feed additive to boost production and Se deposition in eggs and tissues, owing to its high bioavailability, efficient tissue accumulation and minimal toxicity. Selenium-enriched yeast (SeY) is a well-established source, while sel...
