Which element deficient in milk

Fe element is deficient in milk.
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they can digest solid food.
Protein, fat, lactose, and minerals are the four major components in all milk, irrespective of the species. Minerals or milk salts are traditional names for a variety of cations and anions within bovine milk. In addition to calcium, milk is a good source of many other vitamins. Vitamins A, B6, B12, C, D, K, E, thiamine, niacin, biotin, riboflavin, folates, and pantothenic acid are all present in milk, but it lacks iron.
