“…Furthermore, the age of the mare and her parity number should be considered when comparing the results, as previous studies have indicated variations in the concentrations of both Cu and Zn depending on the mare's age [48,49]. This variability may help to explain the high degree of variance observed within the groups in this study.…”

Copper (Cu) and zinc (Zn) are trace minerals with multiple biological functions, playing roles in fetal development and immune regulation. Despite their known significance, research on Cu and Zn administration and supplementation for pregnant mares is insufficient. This study aims to evaluate Cu and Zn serum concentrations monthly throughout the year and through pregnancy in Polish Konik mares. The study was conducted in 2020 on 36 mares from the Polish state stud farm, with 24 mares in the pregnant group and 12 mares in the non-pregnant group. Monthly blood samples were collected, and serum Cu and Zn concentrations were measured. The total Cu concentration in the serum of all mares was higher (p < 0.0001) in August and September (13.98 ± 3.00 μmol/L) than in May, June, July, and November (11.04 ± 2.74 μmol/L). Similarly, the total Zn concentration was higher (p < 0.0001) in August, September, October, November, and December (19.80 ± 9.72 μmol/L) than in May, June, and July (14.50 ± 6.94 μmol/L). No evidence of a linear relation between Cu and Zn concentrations was demonstrated (slopes difference p < 0.001). No differences in Cu (p > 0.05) or Zn (p > 0.05) concentrations were found between pregnant (Cu: 12.08 ± 3.01 μmol/L; Zn: 18.02 ± 9.03 μmol/L) and non-pregnant (Cu: 11.23 ± 2.51 μmol/L; Zn: 18.59 ± 10.37 μmol/L) mares in any of the examined months of the year. In conclusion, the month of the year, rather than pregnancy, affects serum Cu and Zn concentrations.

“…Platelet activation is a physiological response of the hemostatic system to physical activity.The intensive horse training leads to increased platelet aggregation and that hypercoagulability in horses with pulmonary hemorrhages is associated with significant thrombocytosis after the race (Giordano et al 2010). The significant hypocalcemia found in draft horses after rest was confirmed by Pourmohammad et al (2019). Hypocalcemia after exercise can probably be caused in the following ways: binding calcium to the troponin molecule, lactates, phosphates, and plasma albumins, and restoring stored calcium ions within the sarcoplasmic reticulum (Vervuert et al 2002;Dummont et al 2012).…”

Good horse performance depends on a genetic predisposition, training, health status, and optimal values of hematological and biochemical blood parameters. This research aimed to monitor 20 hematological and 15 biochemical blood parameters during different types of physical activity in clinically healthy 20 sports and 20 working horses with an average age of 8.33 years. Sport male horses had higher MCV, MCH, number, and percentage of neutrophils, eosinophils, creatinine, and bilirubin, while mares had higher values of RDW, lymphocytes, monocytes, basophils, MPV, glucose, BUN-to-creatinine ratio. Physical activity in draft horses led to a statistically significant increase in the number of leukocytes and neutrophils and significant hypocalcemia, while in sport horses, there was a significant increase in RBC, HCT, and HGB and significant hypoglycemia after rest. Significantly higher values of neutrophils and creatinine were recorded in male draft horses, while in mares, there were higher values of lymphocytes and amylase. This study proved that sport horses have better aerobic capacity and performance, are better adapted to the type and intensity of physical activity, and are kept in better conditions than draft horses. The different types of physical activity and other physiological factors can significantly change hematological and biochemical parameters in the draft and sports horses. Monitoring of hematological and biochemical blood parameters during different types of exercise is essential to assessing horses' performance, welfare status, and health status.

“…At the same time, results in terms of elemental levels in the blood may be subject to error, since active homeostatic mechanisms compensate for levels in the blood at the expense of reserves in the body [ 8 ]. Many authors point out that the advantage of the hair material is also due to the fact that its mineral composition documents the supply of various elements over a longer time profile than is the case, for example, with blood, where changes can occur in a daily profile [ 9 , 10 ]. Hair is a good matrix for the initial assessment of elemental levels [ 11 , 12 , 13 ].…”

The purpose of the study was to evaluate seasonal changes in selected trace elements such as Fe, Cu, Mn, Zn, and Al in the coat of healthy Hucul horses kept in south-eastern Poland in two different facilities and fed with locally sourced feed. The coat for the study was collected from 24 individuals in autumn, winter, and spring. The concentration of elements in the feed was also determined. The date of collection had a significant effect on the concentration of the micronutrients analysed in the coat of Hucul horses. The highest concentration of Zn was found in the coat taken in summer. The coat taken in autumn had the highest concentrations of Fe, Cu, Mn, and Al compared with the other seasons. The highest concentrations of Fe, Mn, and Al were found in fur taken in winter, with the lowest levels of Zn. Positive correlations were found between the content of iron and manganese, iron and aluminium, and manganese and aluminium in the coat of Hucul horses. A clear inter-individual and inter-stable variability was found, which may indicate the need for further research that also takes into account other factors.
