By authors it is investigated the level of the vital chemical elements in principal components of land ecosystems of animals of Low Volga is investigated. Deficiency of a selenium, iodine and cobalt in soils, plants, sterns, animals and water is established. The amount of copper is in soils on the lower bound of norm. The physiological status delivered of Austria thoroughbred the Simmental cows and young growth is studied. Parameters of blood of cows, calfs and adult cows of Simmental breed of Austrian selection, regions of Russia delivered in recent years in a row are investigated. Communications of hormones, antioxidatic enzymes, vitamins A, by E, C, products of peroxide oxidation of lipids and hematological parameters with level of oligoelementses in the environment, sterns and an organism are found out. The maximum level of a corticotropin before the childbirth is revealed. The hydrocortisone remains on a fixed level about seven months of stylishness, and then - goes down. Low level of a thyroxine in blood of uneven-age animals forms the basis for diagnostics of a hypofunction of a thyroid gland and the hidden form iodic gipomicroelementosis I and Se at ruminant in biogeochemical conditions of the region of Low Volga is established hidden combined gipomicroelementosis to Co. Decrease in integrative function of a mammary gland delivered to Astrakhan region the Simmental cows of Austrian selection is revealed.
