Evaluation Of Serum Levels Of Urea, Creatinine, Sodium And Potassium In Thoroughbred Horses Submitted To Exercise Of Different Intensities

Abstract

In the present study, for six months, paired samples of blood were collected from 10 Thoroughbred race horses undergoing exercises of different intensities, namely: light (walking by step), moderate (trot) and intense (strong gallop). The samples obtained were subjected to analysis for the determination of serum urea, creatinine, potassium and sodium. The results showed that, with respect to creatinine, there was an increase of its concentration in the serum in the three types of exercise, and this increase was proportional to the intensity of the physical effort. An increasing of serum urea was seen only after moderate exercise. The serum concentration of the electrolyte sodium, in turn, remains unchanged before and after the exercises, regardless of their intensity. Finally, with respect to serum electrolyte potassium, no differences were observed between the values after the different types of work.
