“…In another study, LDH and AST contents in the same horses exercised in May and September were measured and it was reported that LDH and AST contents increased after exercise (Kedzierski et al, 2009). In addition, it was found that LDH and AST contents increased after exercise in horses with piroplasmosis (Bravo-Barriga et al, 2022). In a two-race study on endurance horses, it was reported that AST and ALT contents increased substantially in both races compared to the pre-race period (Larsson et al, 2013).…”

The aim of this study was to compare the changes in the content of cTnI, cTnT and some biochemical parameters (CK–MB, LDH, AST, ALT) in Arabian racehorses before and after training. Diagnosis of myocardial disease in horses is very difficult due to the lack of specific cardiac signs. Cardiac diseases are seen as a cause of sudden death or decreased performance in horses. It has also been reported that excessive exercise may cause transient myocardial damage. In our study, 20 healthy stallion Arabian racehorses aged 4–10 y (6.00 ± 0.52 y) were used. Five millilitres of blood was collected from the V. jugularis of clinically healthy horses into serum tubes before and after training. Training time was determined as 30 min for each horse. Pre-training cTnI, cTnT, CK–MB, LDH, AST, and ALT contents were determined to be 0.130 ± 0.01 ng/mL, 0.007 ± 0.00 ng/mL, 231.15 ± 8.96 U/L, 692.45 ± 34.12 U/L, 309.92 ± 18.48 U/L, and 11.83 ± 0.92 U/L, respectively. After training, cTnI, cTnT, CK–MB, LDH, AST, and ALT contents were determined to be 0.169 ± 0.01 ng/mL, 0.008 ± 0.00 ng/mL, 289.80 ± 10.96 U/L, 704.25 ± 22.03 U/L, 328.47 ± 19.58 U/L, and 15.24 ± 1.03 U/L, respectively. As a result, it was determined that exercise triggered myocardial damage to some extent in Arabian horses. Exercise stimulates troponin release and the differences that may occur in troponin tests in horses after exercise should be taken into consideration.

“…Studies on Thoroughbred racehorses reported increased LDH, AST and ALT after exercise (Allaam et al., 2014 ). Horses with piroplasmosis have shown similar increases in LDH and AST due to exercise (Bravo‐Barriga et al., 2022 ). In endurance horses, a significant hike in AST and ALT levels was found after a race compared to pre‐race measurements (Larsson et al., 2013 ).…”

BackgroundThe aim of this study was to examine variations in stress, metabolic, and physiological parameters of horses used in the traditional equestrian team sport of Kök‐Börü in relation to winning and losing outcomes.Material and methodsTo accomplish this, blood samples were taken from horses on four different teams who participated in two separate games, both before and after game. These samples were used to measure levels of cortisol, ACTH, beta‐endorphin, adrenaline, noradrenaline, triiodothyronine (T3), and thyroxine (T4) via species‐specific commercial ELISA kits. The autoanalyzer tested biochemical and hematological parameters. The gathered data were then analyzed statistically based on the teams' winning or losing status.ResultsThe results suggested that winning teams had lower MID, red blood cell, HGB, RDW‐SD, HCT, platelet distribution width, and creatine kinase values post‐game in comparison to their pre‐game state. Conversely, mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH), and CREA values increased in the winning teams' post‐game. Additionally, horses in the winning teams showed a decrease in cortisol, beta‐endorphin, and ACTH levels post‐game but increased levels of adrenaline and T3. Considering the pre‐game values, it was found that GRA and Cl levels were lower in the winning teams. Before the game, adrenaline and T3 levels were higher in the winning teams. No significant difference was observed in post‐game hematological parameters between the teams. However, post‐game K, adrenaline, and noradrenaline levels were higher among the winning teams' horses, while cortisol and beta‐endorphin levels were heightened in horses from the losing side.ConclusionIn conclusion, significant differences were not observed in the distribution of hematological and biochemical parameters of horses following the Kök‐Börü games, regardless of the outcome. However, decreased post‐game cortisol, ACTH, and beta‐endorphin levels in winning teams may suggest better stress management abilities among these horses.

“…Previous studies in Europe have shown a wide range of seroprevalence rates for equine piroplasmosis: T. equi seroprevalence ranged from 1% in the Netherlands to 58% in France, with an estimated overall seroprevalence of 30.0% [12,[32][33][34][35][36][37][38].…”

Equine piroplasmosis (EP) is an endemic tick-borne disease found in most countries around the world. It affects all species of Equidae, and it is caused by Theileria equi, Babesia caballi and T. haneyi. The research herein is the second study on the prevalence of piroplasms in Romania conducted in the past two decades. The aim of this study was to assess the seroprevalence of anti-Theileria equi antibodies and the geographical distribution of this disease in the southwest, west, and northwest regions of Romania in order to obtain a more thorough understanding of the parasitological status of horses in this country. This study included 522 apparently healthy, mixed-breed horses from three different counties. The serum samples were analysed using the cELISA Theileria equi Antibody Test Kit. The overall seroprevalence rate was 12.84%. From the total number of positive horses, 13.96% were females and 11.21% were males. Based on the distribution of positive cases into age groups, the following values were obtained: 0–60 months: 16.26%, 60–180 months: 10.03%, and >180 months: 15.83%. There was no statistically significant difference between samples, based on age or gender. The positivity percentage in the localities included in the study ranged from 8.33 to 100%. In the population under study, the seroprevalence rate was high, indicating a possible exposure risk in this area of Romania, which could have severe effects on equids in the case of clinical manifestations of the disease. EP represents a serious threat for equine health in Romania; therefore, close and continuous monitoring of the situation is required.
