Pigs have been kept to produce meat for 5,000 to 9,000 years. [16] As of 2011, pigs used commercially in the UK and Europe had an FCR, calculated using weight gain, of about 1 as piglets and ending about 3 at time of slaughter. [5]
Used alone, the word feed more often refers to fodder. Animal feed is an important input to animal agriculture , and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like ...
Farrow-to-finish is typically a confinement operation where pigs are bred and raised to their slaughter weight, usually 225-300 pounds. Facilities with a capacity of 2,500 or more swine are considered by the EPA to be concentrated animal feeding operations (CAFOs) subject to point source pollution permit requirements.
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 have a limited tolerance to high temperatures and heat stress can lead to death. Maintaining a more specific temperature within the pig-tolerance range also maximizes growth and growth-to-feed ratio. Indoor piggeries have allowed pig farming to be undertaken in countries or areas with unsuitable climate or soil for outdoor pig raising. [8 ...
Creep feeding is a method of supplementing the diet of young livestock, primarily in beef calves, by offering feed to animals who are still nursing. [1] Creep feed is sometimes offered to swine , [ 2 ] and it is possible with companion grazing animals such as sheep and goats . [ 1 ]
Ractopamine is known to increase the rate of weight gain, improve feed efficiency, and increase carcass leanness in finishing swine. Its use in finishing swine yields about 3 kg (6.6 lb) of additional lean pork per animal, and improves feed efficiency by 10%. [14]
