Study of the correlation between toxic, essential and macronutrients in the blood serum of stud horses

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).
