A dairy herd is a group of cows specifically raised for milk production. These cows are bred and managed to ensure high milk yield and quality. Dairy herds can vary in size, from small family farms with a few cows to large commercial operations with hundreds or thousands of animals. Farmers care for dairy herds by providing proper nutrition, veterinary care, and comfortable living conditions. The milk produced by these cows is collected and processed for various dairy products, such as cheese, yogurt, and butter. Proper management of a dairy herd is essential for sustainable milk production.
