Abstract

Oxidative stress is implied in various pathological conditions in both humans and animals, and recent studies have suggested its role in performance, recovery, immunity, and health. This study’s objective was to investigate whether the higher frequency of activity by hunting dogs influences the oxidative stress indicators subsequent to endurance. The research involved forty-one hunting dogs, with equal representations of Alpine Brack Dachshund, Istrian Coarse-Haired Hound, and Posavina Hound. The dogs were categorized into higher frequency activity (n=22) and lower frequency activity (n=19) groups. Endurance was defined as a wild-boar hunt lasting for eight hours at an outside air temperature amounting to 10°C. Endurance had an impact on several parameters: an increased white blood cell count, neutrophils, and mean corpuscular hemoglobin concentration values, but decreased values of eosinophils and lymphocytes. Non-enzymatic biochemical indicators revealed higher energy expenditure (decreased glucose, total protein, and albumin concentration), hemoconcentration (decreased iron concentration), and elevated enzyme activity (AST, ALT, ALP, and CK-MB) but lower catalase activity. In terms of activity frequency, enzyme biomarker activity showed significant differences. ALT activity in both low- and high-frequency activity canines was notably higher (P<0.05) post-endurance compared to pre-endurance levels. ALP activity was significantly higher (P<0.05) post intense physical activity in higher frequency activity canines, yet lower (P<0.05) in lower activity frequency canines compared to their pre-endurance status. In conclusion, both tested canine groups demonstrated notable signs of oxidative stress subsequent to endurance, without differences between activity frequencies.
