Tilapia is about 1.5, [32] and as of 2013 farmed catfish had a FCR of about 1. [8] It is possible for fish to have an FCR below 1 despite obvious energy losses in feed-to-meat conversion. Fish feed tends to be dry food with higher energy density than water-rich fish flesh. [33]
Less than 200 Swine (weighing over 55 lb) 2,500 or more: 750–2,499: Less than 750 Turkeys: 55,000 or more: 16,500–54,999: Less than 16,500 Laying hens or broilers (liquid manure handling systems) 30,000 or more: 9,000–29,999: Less than 9,000 Chickens other than laying hens (other than a liquid manure handling systems) 125,000 or more ...
A feed ratio is a measure of profitability of animal husbandry, expressed as the ratio between the cost of food and the price of the final product. For example, in pig farming , the hog/corn ratio is the number of bushels of corn equal in value to 100 pounds of live hogs .
Pigs are extensively farmed, and therefore the terminology is well developed: Pig, hog, or swine, the species as a whole, or any member of it. The singular of "swine" is the same as the plural. Shoat (or shote), piglet, or (where the species is called "hog") pig, unweaned young pig, or any immature pig [23] Sucker, a pig between birth and weaning
Pigs are naturally omnivorous and are generally fed a combination of grains and protein sources (soybeans, or meat and bone meal). Larger intensive pig farms may be surrounded by farmland where feed-grain crops are grown. Alternatively, piggeries are reliant on the grains industry. Pig feed may be bought packaged or mixed on-site.
[6] [7] Farmed fish can also be fed on grain and use even less than poultry. The two most important feed grains are maize and soybean, and the United States is by far the largest exporter of both, averaging about half of the global maize trade and 40% of the global soya trade in the years leading up the 2012 drought.

CO 2 and ammonia from the pig manure are reused to grow algae which in turn are used to feed the pigs. [57] Another method to reduce the effect on the environment is to switch to other breeds of pig. The enviropig is a genetically modified type of pig with the capability to digest plant phosphorus more efficiently than ordinary pigs, though the ...
A feedlot or feed yard is a type of animal feeding operation (AFO) which is used in intensive animal farming, notably beef cattle, but also swine, horses, sheep, turkeys, chickens or ducks, prior to slaughter.
