A stock collection is a group of animals, typically livestock, that are kept together and managed as a unit. The term 'HERD' is often used to refer to such a collection, as it implies a large group of animals that are kept together and managed as one. A HERD can be made up of any type of animal, from cows and horses to sheep and goats. Herds are often used for breeding, grazing, and other agricultural purposes.
