| The objective of this experiment was to characterize the heart rate (HR) of twelve Mangalarga Marchador mares, before, during, and immediately after 5, 10, 15 and 20 minutes of marcha tests, evaluating the effect of chrome on cardiac performance. The mares were assigned into three groups distinguished by supplementation of 0, 5 and 10 mg of Cr, respectively. The experiment was conducted in two phases, 24 and 6 days, respectively. The first phase included diet, Cr and exercise adaptation and the second, three 50-minute marcha tests, every other day. Before the tests, a Heart Rate Monitor was adapted to check the HR. The assay was randomly conducted in split-splot arrangement, with four replications. Mean comparisons were performed through minimal... |
