Animal unit months (AUMs) in a grazing area (calculated by multiplying the number of animal units by the number of months of grazing) provide a useful indicator of the amount of forage consumed. On public lands in various jurisdictions, authorized use of forage for grazing is commonly expressed in animal unit months.
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. Many different schemes exist, giving various values to the grazing effect of different types of ...
Animal husbandry is the branch of agriculture concerned with animals that are raised for meat, fibre, milk, or other products. It includes day-to-day care, management, production, nutrition, selective breeding , and the raising of livestock .
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 animal husbandry, a concentrated animal feeding operation (CAFO), as defined by the United States Department of Agriculture (USDA), is an intensive animal feeding operation (AFO) in which over 1,000 animal units are confined for over 45 days a year. An animal unit is the equivalent of 1,000 pounds of "live" animal weight. [1]
In the United States, grazing fees are generally charged per AUM (animal unit month). (Some additional fee or fees may be charged in various jurisdictions, e.g. per application.) On US federal grazing land, the grazing fee for 2012 (as for 2011) is $1.35 per AUM. [3] As of 2015, the grazing fee has been increased to $1.69. [3]
Navajo Livestock Reduction - showing number of 'sheep units' The Navajo Livestock Reduction was imposed by the United States government upon the Navajo Nation in the 1930s, during the Great Depression. The reduction of herds was justified by the government by stating that grazing areas were becoming eroded and had deteriorated due to too many ...
In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting. [1]
