Dairy cattle (dairy cows) are cattle cows (adult females) bred for the ability to produce large quantities of milk, from which dairy products are made.

Historically, there was little distinction between dairy cattle and beef cattle, with the same stock often being used for both meat and milk production. Today, dairy cows are specialized and most have been bred to produce large volumes of milk, with little or no regard for their production of meat.

Dicalcium phosphate, also known as calcium monohydrogen phosphate, is a dibasic calcium phosphate.

It is usually found as the dihydrate, with the chemical formula of CaHPO4 • 2H2O, but it can be thermally converted to the anhydrous form.

It is practically insoluble in water, with a solubility of 0.02 g per 100 mL at 25 °C. It contains about 23 percent calcium in its anyhydrous form, and is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products.

It is also used as a tableting agent in some pharmaceutical preparations.

It is used in poultry feed.
