Probac 1000 contains a special combination of different specific microorganisms in microencapsulated form as well as a unique combination of intestinal regulating carbohydrates. The different bacteria cultures reciprocally support the ability to actively populate the small intestine of the pigeon. They thereby help with the digestive processes, generate essential nutrients, stabilise the natural intestinal flora and strengthen the immune system. They suppress illness-causing bacteria like coccidian, hexamite, E. coli, candida and salmonella and thus effectively prevent intestinal illnesses. The natural intestinal flora is thus quickly and gently regenerated.
