When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
Stand density index (SDI; also known as Reineke's Stand Density Index [1] after its founder) is a measure of the stocking of a stand of trees based on the number of trees per unit area and diameter at breast height (DBH) of the tree of average basal area, also known as the quadratic mean diameter.
The Stoß is a unit of cattle stock density used in the Alps. For each Alm or Alp it is worked out how many Stoß (Swiss: Stössen ) can be grazed (bestoßen) ; one cow equals one Stoß , 3 bulls equal 2 Stöße , a calf is 1 ⁄ 4 Stoß , a horse of 1, 2 or 3 years old is worth 1, 2 or 3 Stöße , a pig equals 1 ⁄ 4 , a goat or a sheep is 1 ...
For trout, stocking rates of 30 to 50 kg/m 3 are normal at the end of a rearing cycle, while for marine species, such as sea bass and sea bream, the achievable load is lower, between 15 and 20 kg/m 3. The total volume required for a raceway is calculated by dividing the total amount of fish in kg by the desired stocking rate in kg per m 3. [17]
In British Columbia, the Range Regulation defines "animal unit month" for purposes of the Range Act. Effectively, the regulation assigns animal unit equivalents of 1 for a cow (either by herself or with an unweaned calf), 0.7 for a yearling of the genus Bos, 1.5 for a bull, 1.25 for a horse, 0.2 for a sheep, 0.2 for a llama, and 0.1 for an alpaca.
The carrying capacity of a farm is commonly determined in Australia by expressing the number of stock carried during a period of feed shortage in terms of their DSEs. [ 1 ] Benchmarking standards used by Grazing for Profit programmes quote that one labour unit (40 hours per week [ 2 ] ) is required for 6,000 DSE (other benchmarking standards ...

Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
