Abstract

Mycotoxicoses of farm animals cause the huge losses on a global scale, therefore the development of new methods for their treatment and prevention mycotoxins entry to organism of animals is still priority in veterinary toxicology.Today the understanding that the vast majority of animals mycotoxicoses cases is the mixed mycotoxicoses, that are resulting toxic effects of complex set of different mycotoxins, which complicates their diagnostics and prevention and treatment.Most of animals mycotoxicoses is a chronic disease at which disturbed metabolism, and the most vulnerable are lymphoid organs, liver, ductless glands and central nervous system. Therefore, treatment of animals should be complex – antidote, pathogenetic and symptomatic,and the search for new tools in the fight against mycotoxicosis in animals is a topical research direction in modern veterinary medicine.The article presents the experimental data about joint action of ochratoxin A and deoxynivalenol on nitrogenous metabolism parameters of broiler chickens. Conditions of nitrogenous metabolism in the organism of broiler chickens were studied by content of total protein, albumin, urea and creatinine. Established that the joint action of ochratoxin A and deoxynivalenol to the broiler chickens manifested dysproteinemia, that is the result of liver protein synthesis function disorder and absorption of protein cleavage products from the small intestine, owing to mucous membrane lesions through toxins. Increase of urea and creatinine in the blood plasma of broiler chickens by combined effect of ochratoxin A and deoxynivalenol is a result of disorder of renal excretory function due to exposure to toxins.
