    The correct concentrations of biological elements allow biochemical processes to proceed normally, and thus enable the proper functioning of the organism. The aim of the study was to determine characteristics of the mineral metabolism of horses raised in a region characterized by mineral deficiencies as a basis for evaluating their diet. Ten horses were selected for the study (5 mares and 5 geldings), all kept in similar conditions. The horses were used for recreation and sport. The study was conducted in two periods: after the pasture season (end of November 2015) and at the beginning of the pasture season (end of May 2016). Blood was collected from the jugular vein into sterile test tubes without coagulant. The evaluation of the concentrations of copper and zinc in the blood serum of the horses revealed substantial deviations from physiological norms. The serum concentrations of Cu and Zn were below the lower reference levels. On the basis of the study it is difficult to conclusively state which factor is decisive in determining the content of calcium, zinc and copper in the serum of horses over the course of the year. It seems likely that the serum concentrations of these elements may be determined by their content in the horses’ feed. Therefore it would be advisable to supplement the supply of copper and zinc in the feed ration in both the summer and winter seasons. Moreover, further research should be conducted in the region to determine the supply of copper and zinc to horses.

    The Use of Serum Protein Electrophoresis in Diagnosis of Horse Diseases
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Jania, Bartosz; Wyganowska, Amelia; Andraszek, Katarzyna; Department of Animal Genetics and Horse Breeding, Siedlce University of Natural Sciences and Humanities, Poland; Department of Animal Genetics and Horse Breeding, Siedlce University of Natural Sciences and Humanities, Poland; Department of Animal Genetics and Horse Breeding, Siedlce University of Natural Sciences and Humanities, Poland
    The aim of the study was to use serum protein electrophoresis for a preliminary evaluation of the physiological condition of horses and detection of potential diseases. The serum electropherogram of healthy horses is characterized by a lack of a prealbumin zone, and 6 different bands can be observed: albumin, α1, α2, β1, β2, and γ-globulin. Numerous pathological states in horses, including liver diseases, innate or acquired immune deficiencies, enteropathies and nephropathies associated with protein loss, local or systemic infections, cancers, and parasites can cause changes in the albumin fraction and globulin concentration. The serum protein level can also change significantly in the case of equine babesiosis. In the horses tested the serum content of albumins and three globulin fractions with their subfractions were determined. The total protein concentration and the ratio of albumins to total globulins (A/G) were determined. Serum protein electrophoresis in horses can be recommended as a screening test for qualitative detection of abnormalities in the major proteins and as an important supplement to detailed calculation of serum proteins.
