VANADIUM IN POULTRY NUTRITION [PDF]
Archives of Veterinary Medicine, 2019 Vanadium (V) is essential element for poultry nutrition. Relatively low level of V (< 10 μg/kg of feed) is known to reduce both growth in chicks and Haugh unit value of eggs. The National Research Council (NRC) recommends the presence of very low levels of V in poultry diets, with the maximum tolerance level (MTL) being 10 mg/kg.
