Abstract
Studies were conducted to assess the elemental composition of the blood serum of 39 Arabian pure breed stud horses. The correlation between the content of toxic elements in the blood serum: aluminum (Al), arsenic (As), cadmium (Cd), lead (Pb), tin (Sn), mercury (Hg), essential trace elements: cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), iodine (I), manganese (Mn), selenium (Se), zinc (Zn) and macronutrients: calcium (Ca), potassium (K), magnesium (Mg), phosphorus (P) was studied. A negative correlation was established between the content of mercury and iron in the blood serum of stud horses (r=-0.34; p=0.04). A negative correlation was also found between the levels of cadmium and calcium in the blood serum (r=-0.40; p=0.02). The establishment of these correlations suggests the presence of competitive relations between these elements in the body of horses. Positive correlations were established between the content of toxic elements in the blood serum: Al/As (r=0.38; p=0.02), Al/Pb (r=0.41; p=0.009), Al/Sn (r=0.56; p=0.002), As/Sn (r=0.46; p=0.0003), Pb/Sn (r=0.32; p=0.05).
Highlights
In modern horse breeding, one of the main trends in the field of reproduction biology is the study of various exogenous and endogenous factors and their impact on reproductive health and the resistance of germ cells to cryopreservation [1], [2]
The purpose of the study is to study the effect of toxic elements on the content of essential elements and macronutrients in the blood serum of stud horses
Our studies allowed to determine the effect of the concentration of toxic elements on the content of essential trace elements and macronutrients in the blood serum of stud horses
Summary
One of the main trends in the field of reproduction biology is the study of various exogenous and endogenous factors and their impact on reproductive health and the resistance of germ cells to cryopreservation [1], [2]. The state of the environment is important in the vital activity of the animal body. Environmental pollution by human industrial activity leads to a violation of the balance of mineral elements in water and soil, which contributes to the development of microelementosis [3], [4]. Micro- and macronutrients contribute to all the metabolic processes of the body: synthesis of proteins, fats, carbohydrates, maintaining osmotic pressure and acid-base balance. The animal body, which exceeds the normative values of the concentration of toxic elements, experiences irregularities in the work of various organs and systems [4]. Toxic elements compete with essential elements and can lead to their deficiency
