Assessment of cardiomyopathy in broiler chickens with combined mycotoxicosis at the ultrastructural level

The purpose of our study was to uncover the issue of the changes manifestation in the broiler chickens heart muscle with combined mycotoxicosis at the ultrastructural level. According to the results of the study, morphological changes in cardiac tissue are noted against the background of combined mycotoxicosis, recorded at the ultrastructural level both morphologically and morphometrically. Broiler chickens cardiomyocytes in conditions of combined mycotoxicosis lose a significant part of the functional mitochondria after 21 days of subacute mycotoxicosis; under these conditions, the non-functional mitochondria proportion in cardiomyocytes may exceed half of all observed. This study confirms the presence of serious pathological changes in the heart tissue due to the effects of a combination of mycotoxins.
