Znaczenie tryptofanu w żywieniu loch i ich potomstwa

Tryptophan is an essential component of the swine diet. Tryptophan requirement of pregnant sows may change from early to late gestation periods. Tryptophan concentration in lactating sow diet influences growth performance of piglets. Piglets fed deficient diet show lower feed intake and lower daily gains. Tryptophan deficiency decreases protein synthesis in liver and skeletal muscles. Piglets with tryptophan deficiency respond with an aversion against tryptophan-deficient diet. They prefer diet with a higher tryptophan content. Some interactions exist between tryptophan and other amino acids, for example valine and leucine. The aim of this paper was to present the aspects connected with tryptophan in nutrition of sows and their progeny.
