Cattle and dairy farming businesses keep and manage cattle, with dairy farms specialising in producing milk. Their work typically includes breeding or sourcing cows and heifers, providing feed and housing, monitoring health and fertility, and arranging veterinary care. Farmers milk cows using parlour or automated systems, maintain milking equipment and keep records of herd performance and milk quality. Milk is commonly collected and supplied to dairy processors for products such as drinking milk, cheese, butter and yoghurt. Some farms also process or sell milk and dairy products directly, where their facilities and business arrangements allow. Dairy farms may rear calves and replacement heifers, sell breeding animals, and keep beef cattle or raise some dairy-bred calves for meat production. The balance of these activities varies between farms, depending on herd size, land, facilities and market arrangements.
