Efeitos da ozonioterapia sobre os parâmetros hematológicos, bioquímicos e estresse oxidativo de cavalos atletas de vaquejada

Abstract

ABSTRACT Ozone therapy is a technique used in several specialties of equine medicine; however, there are few studies on its use in vaquejada (cowboy competition) athlete horses. This study aims to evaluate the potential effect of ozone gas administered by two different routes on hematological and biochemical values and the oxidative stress marker in vaquejada athlete horses. For this, nine healthy equines that followed a training protocol and underwent two treatments were used with an 8-day wash-out between them. The major ozonated autohemotherapy (MOA) treatment group received a volume of 600ml of the O2-O3 mixture at a concentration of 60 µg/mL, and the rectal insufflation (RI) treatment group received 5mL of gas per kg of body weight at a concentration of 15µg/kg performed every 24h on three consecutive days. Results were significant for RBC, hematocrit, and hemoglobin in the hematological variables, and AST and lactate for biochemical and malondialdehyde variables. No statistically significant differences were found in comparisons between treatment groups. Thus, we can conclude that there is no difference between the two therapies, indicating that the two techniques are effective for the application of ozone therapy in horses competing for vaquejada.
