Analysis of the season-dependent component in the evaluation of morphological and biochemical blood parameters in Shetland ponies of both sexes during exercise.

Abstract: Determination of morphological and biochemical blood indices facilitates assessment of the health and welfare of horses, their nutrient demand, the effects of training already undertaken, and the horses' suitability for exercise. Identification of the season-dependent components and the effects of sex and exercise on changes in frequently referenced haematological and biochemical parameters was the main goal of the current study. Unassigned: The blood morphology of 21 healthy adult Shetland ponies (11 mares and 10 stallions) aged 6.5 ± 1.4 years from the central Pomeranian region in Poland was analysed. Blood samples were taken once per season for one year. Unassigned: No statistically significant season-dependent differences were found in the blood morphology parameters in either mares or stallions before or after exercise. Beta-coefficient results revealed the strength and type of the relationship of red blood cell distribution width (RDW) and granulocyte count (GRA) with the season, of red blood cell count (RBC), haematocrit, mean corpuscular volume and mean platelet volume with the sex, and of RDW, white blood cell count, GRA and RBC with the exercise factor. Biomarkers demonstrating the relationship between aerobic and anaerobic levels of energy metabolism in the blood did not show any sex dependency in regression analysis. Unassigned: The sex-independence of energy metabolism biomarkers may indicate the universality of these parameters. Both seasonality itself and its combination with the exercise factor took part in the formation of effective adaptive reactions for maintenance of morphological blood indices in the ponies during exercise.

This research aimed to understand the seasonal variations and the impact of sex and exercise on common blood parameters in Shetland ponies. Results indicate that neither the seasons nor the pony’s sex significantly influenced these blood characteristics. However, the exercise factor did show its effect on certain hematological parameters.

About the study

In this research, the blood morphologies of 21 healthy adult Shetland ponies, composed of 11 mares and 10 stallions, aged around 6.5 years, were analyzed. The data was collected once per season over the period of a year. The particular focus was on understanding the effects of the seasons, sex, and exercise on commonly referenced hematological and biochemical parameters in these ponies.

Findings

  • No significant seasonal fluctuations were found in the blood parameters of either the mares or the stallions before or after exercise. Thus, seasonality does not seem to impact the morphological blood indices in these ponies.
  • Certain blood parameters did show a relationship with the factors of the season, sex, and exercise, as depicted by the Beta coefficient. These include the red blood cell distribution width and granulocyte count (related to season), red blood cell count, haematocrit, mean corpuscular volume, and mean platelet volume (related to sex), and red blood cell distribution width, white blood cell count, granulocyte count, and red blood cell count (related to exercise).

Implication of the findings

  • The researchers suggest that the lack of sex dependency in the biomarkers linked to aerobic and anaerobic levels of energy metabolism might hint at these parameters being universal.
  • Despite the seasons not directly influencing the blood parameters, both seasonality and its interaction with the exercise factor seem to play a role in forming effective adaptive reactions. These adaptations help in maintaining the morphological blood parameters in these ponies during exercise.

These findings add to the understanding of the factors influencing the blood parameters in sport horses, which could support improved health and welfare assessments, as well as nutrition and training planning for these animals.
