Intossicazione da alcaloidi: materie prime, micotossine e salute della scrofa

Le materie prime sono necessarie per l’alimentazione delle scrofe, poiché forniscono energia, proteine e nutrienti. Tuttavia, spesso nascondono insidie, quali i fattori anti-nutrizionali. Le micotossine sono alcuni di questi e sono estremamente numerose e pericolose per i riproduttori suini.
