МОДЕЛИРОВАНИЕ ПОСТУПЛЕНИЯ МИКРОЭЛЕМЕНТОВ В ОРГАНИЗМ ЖИВОТНЫХ И РАСПРЕДЕЛЕНИЯ ИХ ПО ОРГАНАМ

The influence of Cd, Zn on the chemical composition of animal organs that consume feed enriched with these microelements during anthropogenic entry into the soil was studied. The obtained data allow us to find critical levels of trace elements in the soil and crop products grown on it, which have a toxic effect on the animal body.Изучено влияние Cd, Zn на химический состав органов животных, потребляющих корма, обогащенные данными микроэлементами при антропогенном поступлении в почву. Полученные данные позволяют найти критические уровни содержания микроэлементов почве и выращенной на ней растениеводческой продукции, оказывающие токсическое действие на организм животных

ECOLOGICAL AND TOXICOLOGICAL EVALUATION OF THE IMPACT OF SELENIUM CONTAINED IN FEED ON MORPHOLOGICAL AND FUNCTIONAL CHANGES IN THE BONE TISSUE OF ANIMALS

Physiological role and toxic-metric characteristics of selenium compounds for animals and humans are poorly studied. In this regard, this article studies morphological changes in bone tissue against the background of selenium intoxication within a chronic experiment. 2 groups of animals were studied during the experiment - reference and experimental ones. Animals (Wistar rats) received plants (rapeseed, spring wheat) grown on meadow chernozem soil using selenium at a dose of 2 MAC (Selenium experimental group). An increase in selenium concentration in the diet leads to reactive changes in osteogenic process
