Calculations have shown that the overall fed aquaculture FIFO declined from 0.63 in 2000 to 0.33 in 2010, and 0.22 in 2015. In 2015, therefore, approximately 4.55 kg of farmed fish was produced for every 1 kg of wild fish harvested and used in feed. (For Salmon & Trout, the FIFO ratios for 2000, 2010, and 2015 are: 2.57, 1.38, 0.82.) [30]
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
Intensive pig farming, also known as pig factory farming, is the primary method of pig production, in which grower pigs are housed indoors in group-housing or straw-lined sheds in establishments also known as piggeries, whilst pregnant sows are housed in gestation crates or pens and give birth in farrowing crates.
Prior to 1910, fish meal was primarily used as fertilizer, at least in the UK. [2]Fish meal is now primarily used as a protein supplement in compound feed. [2] [3] As of 2010, about 56% of fish meal was used to feed farmed fish, about 20% was used in pig feed, about 12% in poultry feed, and about 12% in other uses, which included fertilizer. [1]
Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%, [1] along with silica and other dross, which makes it brittle and not useful directly as a material except for ...
Parsons et al. (2006), evaluating different corn particle sizes in the broiler feed found that the largest particle size (2.242 mm) gave better feed intake than the other particle sizes tested (0.781, 0.950, 1.042 and 1.109 mm). Nir et al. (1994), however, argued that the development of broilers was influenced by changing particle sizes ...
Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word feed more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the
During World War II, a collection of pig swill was a nationwide campaign in Great Britain. [3] During the 2001 United Kingdom foot-and-mouth outbreak, it was thought that unprocessed pig swill was a key link in the chain of the infection, and it was banned in Great Britain. In 2003, the ban was expanded to the whole European Union. [4]
