This study was undertaken to determine changes in heart rate and blood lactate in dif-
ferent breeds of horses and mules during the course of a cavalcade through the Pantanal
Twelve adult horses of various breeds (Pantaneiro, Criollo and crossbred Criollo) and four
mules were studied during 12 days of cavalcade (340 km). Register of heart rate and col-
lect of blood samples from animals were made in the afternoon, the day before the caval-
cade (pre) and also taken 30 min. after the animals travelled 340 Km (post). Serum con-
centrations of lactate were measured using a spectrophotometer Spekol and heart rate using a stethoscope. Data were analysed ysung a t-test for paired comparisons for each
breed. Data of all breeds were analysed using ANOVA and the Tukey procedure was used for the values pre and after cavalcade. Although there were no differences pre and
post cavalcade for heart rate and lactate in each breed and mules and between groups
(p<0.05), lower mean values at rest (43 beats/min and 0.63 mmol/l) were found for the
Pantaneiro horses for heart rate and lactate, respectively. Thus, Pantaneiro horses appea-
red to be better adaptated than other breeds before and after the ride in the Pantanal conditions.
