the house-pig was bred before approximately 9000 years from the boar, in fact in Eastern Europe, in the Mediterranean-area and in southeast-Asia. Today, house-pigs live above all in North America, Europe and China and virtually cover one tenth of the animal protein-demand of the people. By the Haustierzüchtung, the growth and on the other hand the descendant-number was increased considerably on the one hand. So, Z could. B. in relatively short time the length of the pig and the number of its ribs the butcher-day increases and is increased so.

The original forms of Central Europe's pigs became until in the 19. Century to the so-called acorn-post and to grazing into the forests driven. These pigs had Stehohren and a relatively long skull. The Hannoversche pasture-pig is such a race. Races, that were fast-growing and precocious and delivered a higher profit with it, later were introduced country-pig or the Berkeshire-Schwein like the ennobled. Many of the older races, that now are no more economic, vanish little by little, according to also the Hannoversche pasture-pig or the Unveredelte Bayerische country-pig. However, saddle-pig is still held in Schleswig-Holstein as pasture-pig the black-and-white angler.

Also in Asia, a multiplicity of breeding-races like the Chinese mask-pig and the Vietnamese Hängebauchschwein with Senkrücken and extremely short muzzle was created.

The decrease of the skull is a mark of the house-pig. In Poland and Bess-Arabia, Einhuferschweine, with which only one claw and an anus-claw either remained gotten or merged the two main-claws together, were created. A big race with curl-fur, with which the boys still roved, is the Mangaliza-Schwein Hungary.

The production could be increased by pork with us even further in that one moved on to the mass-animal-attitude, a procedure, that takes on the elementary life-needs of the pig of no regard. it often are on closest area of crowded pigs, that nibbles ears and tails mutually for itself and becomes extremely susceptible to infection-illnesses, that must be fought by antibiotics on the other hand, the consequence of massive behavioral-disturbances so.
