Abstract
Trace mineral supplementation is essential for poultry. Inorganic trace minerals are added to feed in the form of inorganic salts, such as sulfates, oxides, and carbonates. However, their bioavailability is low due to the antagonism and interactions among trace minerals, as well as with other compounds forming insoluble compounds, and preventing their absorption by the body. Hence, they are usually added to the diets at levels higher than the bird’s actual requirements causing environmental pollution due to higher excretion of minerals in droppings. The organic trace minerals are specific metal amino acid complexes from a combination of soluble metal salts and amino acids having higher bioavailability. Studies on use of organic trace minerals in layer breeders are meager.
