The livestock unit, abbreviated as LU (or sometimes as LSU - Livestock Standard Unit.), means a standard measurement unit that allows the aggregation of the various categories of livestock (various species, sex and age) in order to enable them to be compared. Data on animals are converted into livestock units using the following coefficients: - equidae 0.80, - young cattle aged less than 1 year old (calves) - 0.40, - male bovines aged between 1 and 2 years - 0.70, - female bovines aged between 1 and 2 years - 0.70, - male bovines of 2 years and over - 1.00, - heifers of bovines of 2 years and over - 0.80, - dairy cows - 1.00, - other cows (sucklers) - 0.80, - sheep - 0.10, - goats - 0.10, - piglets with a live weight of less than 20 kg - 0.027, - breeding sows with a live weight of 50 kg or more - 0.50, - other pigs (young pigs with a live weight of 20 kg or more but less than 50 kg, breeding boars and fattening pigs with a live weight of 50 kg and more) - 0.30, - broilers of chickens - 0.007, - laying hens - 0.014, - other poultry (ducks, turkeys, geese, domestic quails, guinea-fowls, and the other poultry but apart from ostriches) - 0.030, - ostriches - 0.35, - female of rabbits - 0.020

The reference unit used for the calculation of livestock units (=1 LSU) is the grazing equivalent of one adult dairy cow producing 3 000 kg of milk annually, without additional concentrated foodstuffs.
