Answer
A livestock unit (LU) is a standard measurement used in agriculture to represent the amount of feed consumed by livestock. Specifically, it is based on the feed intake of a mature cow weighing approximately 550 kg. A livestock unit can also be expressed in terms of dry matter consumption, typically equivalent to 12 tonnes per year. This concept allows farmers to quantify and compare the nutritional value required for different types and weights of livestock on a farm.
