Kovalchuk I. Physiologico-biochemical indices in blood, milk and tissues of cowsorganism after alimentary loading by cadmium and zinc

The object of investigation biochemical processes in cows organism and heifers on the higher levels of zinc and cadmium in the rations. The purposes of research are to elucidate physiological mechanisms action on cows of the higher levels of zinc and cadmium in the rations, transformation of them with milk and cumulation in tissues of separate organs. The methods of research and equipment - hematologic, physiological, biochemical, clinical, photoelectronic calorimeter, microscope, Goryaev apparatus, gas-flow chromatograf "Chrom-5", spectrumphotometr SPK - 115. The theoretical and practical results of research, scientific novelty - influence on cows organism of the higher levels of zinc and cadmium in the rations, transformation of them with milk and cumulation in tissues of separate organs. It is shown, that the physiologico - biochemical influence of additions of zinc and cadmium in a ration on metabolic processes and reactivity of heifers organism. It was shown the influence of heavy metals on the concentration of different elements in organism and also dynamics of content in an arterial and vein blood and intensity of sorbtion of separate metabolites and heavy metals by a milk gland from blood, concenstration of them in the tissues of internal organs under the five days experimental increasing of sulfate of cadmium. Introduced - It is developed and the approved composition of forage addition on the basis of preparation "Sel-Pleks", that promotes production and reproduction power of cows organism on the condition of their location in the area of the promoted loading. The field of applicationis animal breeding, veterinary medicine.
