PROBI-ZYME contains probiotics. These are good bacteria present in the bird's intestines (and crop). In addition to the good bacteria, PROBI-ZYME contains special enzymes that promote the digestion of the food eaten. The combination of both, if administrated at high doses, guarantees optimal functioning of the digestive system. PROBI-ZYME is one of the few products in which the concentration of good bacteria is guaranteed.
