Necrotic enteritis and biotin deficiency in birds
The presence of Clostridium in the food of the birds is practically continuous due to the resistance of the spores to the thermal treatments.
Its development is favored by the undigested protein in the intestine giving rise to necrotic enteritis. However during the last months it is verified that exists another triggering factor: Biotin deficiency.
Thus the weakness of intestinal integrity, a consequence of this deficiency is a factor that favors the installation of Clostidium in vegetative form of the intestinal mucosa as you can observe in these photos.
