The main product of a cow is milk. Dairy cows are specifically bred to produce large quantities of milk, which can be processed into various dairy products, including cheese, butter, yogurt, and cream. Milk from cows is a significant source of nutrition for many people around the world, providing essential vitamins, minerals, and proteins. The lactation process begins after a cow gives birth, and cows typically produce milk for about ten months postpartum. Dairy farming plays a crucial role in agriculture and the economy, supporting both local communities and international markets as a staple food source.
