This simple method is sometimes used for cattle. The number of animal units represented by one or more head of cattle may be calculated by dividing their total body mass in kg by 454 (or dividing their weight in pounds by 1000). Thus an 800-pound steer would be considered equivalent to 0.8 animal units. [4] Estimation based on metabolic body size.
Various formulas are used for calculating grazing fees on public lands. Some examples are: For federal rangelands of the United States, the grazing fee "equals the $1.23 base established by the 1966 Western Livestock Grazing Survey multiplied by the result of the Forage Value Index (a derived index of the relative change in the previous year's average monthly rate per head for pasturing cattle ...
For example, using UK government Livestock Units (LUs) from the 2003 scheme [1] a particular 10 ha (25-acre) pasture field might be able to support 15 adult cattle or 25 horses or 100 sheep: in that scheme each of these would be regarded as being 15 LUs, or 1.5 LUs per hectare (about 0.6 LUs per acre).
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.
The unit represents the amount of feed required by a two-year-old, 45 kg (some sources state 50 kg) Merino sheep (wether or non-lactating, non-pregnant ewe) to maintain its weight. One DSE is equivalent to 7.60 megajoule (MJ) per day.
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.

A marginal tax on the sellers of a good will shift the supply curve to the left until the vertical distance between the two supply curves is equal to the per unit tax; other things remaining equal, this will increase the price paid by the consumers (which is equal to the new market price) and decrease the price received by the sellers. Marginal ...
For example, beef products and leather are joint products. If a company runs both a beef processing operation and a tannery an increase in the price of steaks would mean that more cattle are processed which would increase the supply of leather. [3] Conditions of production: The most significant factor here is the state of technology. If there ...
