Minerals are essential for animal health, production and reproduction. Trace minerals are only needed in small amounts. Minerals needed in larger quantities are often referred to as macrominerals. Mineral deficiencies disrupt health and performance, but oversupply can cause toxicity

There are seven recognized macrominerals in animal diets: Calcium, phosphorus, magnesium, sulfur, potassium and sodium. They are important for bone structure, water balance and amino acid structure.
