Cow milk is highly nutritious and rich in proteins, Vitamin B2, B12, calcium, and Vitamin D. Cheese, buttermilk, custard, and other dairy products also provide potassium, phosphorus, magnesium, and a variety of vitamins.

Countries around the world produce both small and large farms to raise dairy cattle to produce larger amounts of raw milk and improve the rate of their consumption and exports to other parts of the world.

The dairy industry is the driving force of some economies and different countries are working to improve their dairy technology to become the world’s largest milk producers and exporters.

The largest milk-producing countries are defined by a number of characteristics which include: a large number of head of cattle, functioning milk production facilities, and a large number of cow farms.
