Oral lesions in broilers caused by corn mycotoxins: Review

Abstract

Bird breeding is based on the use of grains that require quality for the processing of the rations. Among the possible contaminants that affect the success of the enterprise are mycotoxicoses caused by fungi, from the field to the storage of the ingredients present in the formulations of the diets. The toxins with the greatest impact on poultry farming are aflatoxin B1, ochratoxin A, T-2 toxin and diacetoxiscirpenol (DAS), vomitoxin and deoxynivalenol (DON), zearalenone and fumonisin B1. These compounds cause losses in production, as a result of lower feed intake, mainly for causing lesions in the oral route of the animals, which consequently decreases the weight gain, feed conversion, and meat and egg production, as well as metabolic disorders. Maize consists of a grain with a greater presence of these mycotoxins, being extremely important the monitoring of its qualification in order to offer rations with nutritional and sanitary safety, with success in the business and products of quality and food safety for human consumption.
