ВПЛИВ САРКОЦИСТ НА МІКРОСТРУКТУРУ М’ЯСА

Abstract

The histological changes of veal of different categories of fattening under conditions of sarcoid lesions are investigated. The material for the study was veal of the second category of fattening and honey, obtained from the enterprises "Nadiya", OJSC "Zapadinka" of the Kyiv region. The slaughter was carried out at Agrarnik CJSC (Bila Tserkva city). Histological studies of muscle, liver, heart and kidneys were conducted. It was established that vein damage by sarcocysts does not depend on feed diet. However, the intensity of invasions of sarcomas of skeletal muscles and heart in noncategory animals was significantly higher, while in veal II category the fat content was much lower. In 30 % of cases sarcocysts were detected in cases of weak invasion, 60 % of cases - in the case of secondary infestation. In the case of weak invasation, veal slaughter products of the second category of fattening in 20 % of cases affected the muscle tissue, in 10 % of cases - the heart muscle. The muscle contracted by sarcastic organs obtained from thin animals during histological studies had characteristic signs of necrotic processes Muscle fibers were thinned, fragmented, largely lost in transverse bandages, were atrophied in locations of sarcocysts. From the condition of moderate to weak muscle invasion, necrotic changes (lysis and fragmentation of muscle fibers) were observed in the muscles. Key words: sarcocysts, veal, histological studies, muscle tissue, kidneys, heart, liver.
