CHANGE OF THE CONTENT OF MICROELEMENTS IN THE BONE TISSUE OF PIGS UNDER THE INFLUENCE OF MINERAL ADDITIVES
Zeolite-containing tuff - natural minerals - have always been used by wildlife. Long known natural way of regulation of the organism's internal environment is geophagy. Wild animals, birds during difficult for the body periods of life, for example, in the spring with the depletion of nutrients, after an illness, in rut, bearing offspring found zeolites in nature and eat them. In the stomachs it is found a significant number of zeolites: elk, for example, up to 5 kg, partridges up to 80% of the content of goiter. Human also suffer from it - eating so-called «coal oil», «land-cream», various clays, which usually turned out to be zeolite-containing tuff. The use of zeolites allows: to improve the nutritional properties of mixed fodder, positively influence on the processes of digestion in organism of animals, improve the efficiency of absorption of useful substances, improve the physiological state of animals, increase the viability of animals, to prevent certain diseases, to increase the productivity of animals, adsorb and excrete animals radionuclides, ammonia, carbon monoxide, carbon dioxide, hydrogen sulfide and heavy metals. Application of mineral natural zeolite in livestock (especially in poultry) gained relevance nowadays in connection with the violation of centralized provision of livestock by mineral additives. Thus, studies assure that feeding by siliceous as feed for pigs can significantly enrich their diet with additional microelements. Under the influence of zeolites Siuch-Yushanskogo deposits it was observed a trend to increase of iron, copper, zinc, manganese in the tissue of the tubular bones of pigs.
