A single adult needs to consume about four pounds (two kilograms) of food each day in order to stay healthy and grow at a normal rate. The amount required varies depending on the breed and the environment in which it lives; for example, animals raised near water sources will likely require less grazing time because their diet consists primarily of grasses found in these areas.Some breeds prefer certain types over others, such as alfalfa hay versus oat straw feedings, which means that their overall caloric intake is based on the hay’s location.
