VETERINARY AND SANITARY EVALUATION OF SLAUGHTER BYPRODUCTS OF THE HORSES GROWN IN ANTHROPOGENIC POLLUTION AREA
As a result of the emissions of significant amount of toxic elements into the atmosphere, a number of territories in the region acquire the status of biogeochemical provinces of anthropogenic origin. Toxic elements on these territories enter the animal body through the feed, where they are accumulated and negatively affect metabolic processes. The purpose of the study was to make veterinary and sanitary evaluation of slaughter byproducts of the horses that were reared in anthropogenic provinces; and to develop the method for correcting their metabolic processes. The studies were conducted on the basis of the “Istok” complex of Verkhneuralsk district of Chelyabinsk Region. At the first stage of the study environmental objects were monitored, the soil, fodder crops, water, snow and blood samples were examined in order to determine toxic elements content in them. At the second stage 2 groups of horses (n = 5) were formed for the correction of metabolic processes; they were fattening at the age of 2-2.5 years with the live weight of 350-370 kg. Control group was kept on a regular diet adopted at the farm, and experimental group received “Vitartil” mineral feed supplement in addition to basic ration, at the dose of 0.1 g per 1 kg of live weight for 60 days. Blood samples were taken in the dynamics of the 1st (background), the 30th and the 60th day of the study. Chemical analysis of environmental objects showed that all of them contained high level of toxic elements and iron. Similar data were obtained from the blood samples of experimental group horses. In organoleptic, physical and chemical, microscopic and toxicological studies, horse meat did not meet the requirement standards. On the 60th day of the study, onthe background of pharmaceutical correction, the nickel content in experimental horses’ blood decreased by 13.4 %, the lead - by 10.4 %, the cadmium - by 33.4 %, the iron - by 37.2 %. The use of “Vitartil” contributed to the improvement of horses slaughter byproducts in the complex of organoleptic, physical and chemical, microscopic and toxicological studies, in comparison with the horses of the control group.
