Vakhutkevych I. Metabolic processes in the hens treated with high doses of dietary chromium and cadmium and with using of zeolite

Object - the metabolic processes in the body laying hens for the experimental introduction in the diet of chromium and cadmium with the addition of zeolite. The goal - finding rifled and the cumulative effects of chromium and cadmium on the metabolic processes and productivity of laying hens and the possibility of preventing the negative impact of chromium and cadmium in their diet by feeding the activated zeolite. Methods - haematological, biochemical (spectrophotometric), livestock, statistics. Investigated the effect of simultaneous administration in the diet of laying hens trivalent chromium and cadmium on hematological parameters, acid-base status of blood lipid peroxidation and protein metabolism, enzyme activity of the antioxidant system, chromium and cadmium in the organs and tissues of laying hens and their the impact on the weight of internal organs and egg production. It is shown that the cumulative effect and rifled Cr3 + and Cd2 + is associated with a significant build up in the kidneys, the liver, which affects the performance of the metabolism and productivity of laying hens. Theoretically proved and experimentally proved that the basis of the mechanism rifled and the cumulative effects of heavy metals is their ability to influence the metabolic processes in the body of poultry, in particular exhibit an inhibitory effect on the enzyme systems, protein synthesis function of the liver, and change the level of the ratio of individual protein fractions and be cumulative action in the organs and tissues of laying hens.The ability of trivalent chromium to reduce the negative impact of cadmium metabolism in laying hens, as well as, the possibility to avoid the toxic effect of chromium and cadmium by the use of activated zeolite, which has a positive effect on the course of metabolic processes and productivity of poultry.
