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 .
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. The intensive piggery system, where pigs are confined in individual stalls, allows each pig to be allotted a portion of feed.
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]
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]
The regular feed conversion ratio, i.e. output fish mass divided by total feed mass. The conversion ratio only taking into account the fish-based component of fish feed, called the FIFO ratio (or Fish In – Fish Out ratio). FIFO is fish in (the mass of harvested fish used to feed farmed fish) divided by fish out (mass of the resulting farmed ...
The use of agricultural land to grow feed rather than human food can be controversial (see food vs. feed); some types of feed, such as corn , can also serve as human food; those that cannot, such as grassland grass, may be grown on land that can be used for crops consumed by humans. In many cases the production of grass for cattle fodder is a ...
English: This Order which is made under the Animal Health Act 1981 replaces the Movement and Sale of Pigs Order 1975 and, so far as they relate to pigs, the Movement of Animals (Records) Order 1960 and the Markets, Sales and Lairs Order of 1925. It also implements some of the requirements of Council Directive 92-102-EEC on the identification ...
