Changes in quality indicators of meat at sarcocystosis

Abstract

Goal. To study morphological changes of muscle tissue for sarcocystistic invasion. Methods. The material for the study is beef (skeletal muscle, liver, heart, kidneys). Methods are pathomorphological. Results The defeat of cattle with sarcocystosis does not depend on the level of feeding. However, the intensity of sarcoid invasion of the skeletal muscles and the heart of thin animals is significantly higher compared to the second category of fattening beef. In muscle fibers of thin animals affected by sarcocystosis, necrotic processes, thinning of muscle fibers, their fragmentation, absence or weak transversal striation of muscles, destruction or atrophy of muscle fibers in places of sarcocyst placement have been revealed. Conclusions The moderate and weak intensity of sarcotism invasion is accompanied by the development of pathological changes in the muscles.
