Livestock Units

Livestock Units(LUs) are a way of comparing the nutritional requirements of grazing animals. They therefore assist with the calculation of stocking densities.

One LU will require roughly one acre of land for summer grazing and one acre of land for conservation to provide forage for winter.

A mature 650kg Friesian cow producing a 45kg calf and 4,500 litres of milk at 3.6% butterfat is 1 livestock unit.
