In animal husbandry, feed conversion ratio (FCR) or feed conversion rate is a ratio or rate measuring of the efficiency with which the bodies of livestock convert animal feed into the desired output. For dairy cows, for example, the output is milk, whereas in animals raised for meat (such as beef cows, pigs, chickens, and fish) the output is the flesh, that is, the body mass gained by the animal, represented either in the final mass of the animal or the mass of the dressed output. FCR is the mass of the input divided by the output (thus mass of feed per mass of milk or meat). In some sectors, feed efficiency, which is the output divided by the input (i.e. the inverse of FCR), is used. These concepts are also closely related to efficiency of conversion of ingested foods (ECI).

Feed conversion ratio in the context of Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products. Grazing is often done on lands that are unsuitable for arable farming, although there are occasions where arable lands and even prior farmlands are intentionally kept or converted to pastures to raise commercially valuable grazing animals.
Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site.
Feed conversion ratio in the context of List of rabbit breeds
As of 2017, there were at least 305 breeds of the domestic rabbit in 70 countries around the world raised for in the agricultural practice of breeding and raising domestic rabbits as livestock for their value in meat, fur, wool, education, scientific research, entertainment and companionship in cuniculture. A rabbit breed is a distinct strain created through selective breeding (or occasionally natural selection) for specific characteristics, including size, fur, body type, color, feed conversion ratio, et cetera. Organizations such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) have standards for the desired qualities of their respective recognized breeds. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the perfect example for the breed, defined by the individual breed standard by which it may be judged. The global diversity of breeds reflects the breadth of the rabbit's unique qualities. Listed below are 191 of the world's modern-day rabbit breeds.
