Diagnostics of the hidden form of hipomicroelement of the quails

Today, the breeding of poultry, particularly quail, is of great importance for most regions of the Russian Federation, which are characterized by rapid growth, development and their productive qualities. And since this bird species has a high level of metabolism, the quail is very sensitive to a deficiency of physiologically important trace elements, especially during acclimatization in various biogeochemical regions of Russia. In this paper, the dynamics of microelements in organs and tissues of quails in the conditions of the arid zone of the Lower Volga region has been studied. Their micronutrient status is described. The low level of selenium and iodine in the soils and plants of the Astrakhan region correlates well with the poor supply of organs and tissues with these elements and has a negative impact on the availability of microelements (Se, J, Co) for organs and tissues of quails, and the low level of selenium and iodine in the quails similar data on quails from the "reference" region can serve as one of the diagnostic indicators of deficiency of these microelements in the body and is a constantly acting stress factor capable of causing a closed form of combined (Se, J) hypomicroelementosis.
