All this, to achieve high production at a good price. This breeding has, however, the drawback of high contamination and lower quality. Extensive livestock farming is based on the occupation of large areas where livestock itself finds its food. Their profitability is lower, but provides a higher quality product. An example is the ham, which is obtained from a pig living on the air free and feed on acorns.
