Abstract: | The effect of an application of pST- and beta-agonists on the fattening-capacity and carcass-composition of the pig is evaluated by means of data available in literature. American stress-resistant cross-bred pigs show a stronger reaction on pST in their fattening-capacity than European breeds. Obviously, this has derived from genetic differences. Feed-utilization, meat-gain, and reduction of lipid content in the case of European breeds are, nevertheless, subject to a pronounced improvement through pST and beta-agonists. Further positive aspects are the decrease of the N-excretion in urine and no, resp. only minor influence on the quality of meat. A negative aspect of the meat with regard to consumers' acceptance is the fact that the mentioned substances belong to the group of hormones. |
