Answer
A livestock unit (LU) is a measure used to standardize the amount of feed required by animals. It is defined as the amount of feed consumed by a mature cow weighing approximately 550 kg. The concept helps in managing and assessing grazing land and feed resources efficiently.
In broader terms, a livestock unit can also be interpreted as equivalent to 12 tonnes of dry matter consumed per year, allowing farmers to make informed decisions about livestock stocking rates and feed management.
