Livestock grazing comparison is a method of comparing the numbers and density of livestock grazing in agriculture.Various units of measurement are used, usually based on the grazing equivalent of one adult cow, or in some areas on that of one sheep.
Thus an 800-pound steer would be considered equivalent to 0.8 animal units. [4] Estimation based on metabolic body size. In this method, which has been suggested for cattle, the number of animal units represented by an animal can be calculated as the ratio of that individual's body mass (in kg) to the 0.75 power, divided by 454 to the 0.75 power.
An animal unit is the equivalent of 1,000 pounds of "live" animal weight. [1] A thousand animal units equates to 700 dairy cows, 1,000 meat cows, 2,500 pigs weighing more than 55 pounds (25 kg), 10,000 pigs weighing under 55 pounds, 10,000 sheep, 55,000 turkeys, 125,000 chickens, or 82,000 egg laying hens or pullets.

This article is currently called Livestock Unit, and it covers various measures of livestock equivalence going under this name.However, there are other measures of livestock equivalence with different names, which are really exactly the same thing: for example Dry Sheep Equivalent, Animal unit, Ruminant Livestock Unit, Unité Bovin Tropical and Unité-Gros-Bétail.
Dry Sheep Equivalent (DSE) is a standard unit frequently used in Australia to compare the feed requirements of different classes of stock or to assess the carrying capacity and potential productivity of a given farm or area of grazing land.
In the United Kingdom the paddock is measured in LU, livestock units, although different schemes exist for this. [24] [25] New Zealand uses either LU, [26] EE (ewe equivalents) or SU (stock units). [27] In the US and Canada the traditional system uses animal units (AU). [28] A French/Swiss unit is Unité de Gros Bétail (UGB). [29] [30]
In older English sources such as the King James Version of the Bible, cattle refers to livestock, as opposed to deer which refers to wildlife. Wild cattle may refer to feral cattle or to undomesticated species of the genus Bos. When used without a qualifier, the modern meaning of cattle is usually restricted to domesticated bovines. [15]
Being a ratio the FCR is dimensionless, that is, it is not affected by the units of measurement used to determine the FCR. [3] FCR a function of the animal's genetics [4] and age, [5] the quality and ingredients of the feed, [5] and the conditions in which the animal is kept, [1] [6] and storage and use of the feed by the farmworkers.
