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.

An animal unit is the equivalent of 1,000 pounds of "live" animal weight. [1]
Industrial production of pigs and poultry is an important source of greenhouse gas emissions and is predicted to become more so. On intensive pig farms, the animals are generally kept on concrete with slats or grates for the manure to drain through. The manure is usually stored in slurry form (slurry is a liquid mixture of urine and feces).
Broiler breeder farms raise parent stock which produce fertilized eggs. A broiler hatching egg is never sold at stores and is not meant for human consumption. [9] The males and females are separate genetic lines or breeds, so that each line can be selected for optimal traits for productivity in either females or males, rather than a single line in which a compromise is reached between female ...
The chicken breeds recognized by the American Poultry Association are listed in the American Standard of Perfection. They are categorized into classes: standard-sized breeds are grouped by type or by place of origin, while bantam breeds are classified according to type or physical characteristics.
