Uso do teste de esforço a campo na avaliação do condicionamento físico de equinos da Cavalaria da Polícia Militar do Estado de Sergipe

Abstract

This study aimed to evaluate the performance and aerobic threshold horses Mounted Police Squadron of Cavalry of the State of Sergipe, who work in the average intensity low activities. Fifteen horses, crossbred ages eight to eighteen, were subjected to the stress test field, lasting 20 minutes divided into six speeds (from 2,5 to 9 m/s). During and post-test samples were collected for measurement of lactate dehydrogenase (LDH) (rest and speeds of 0, 5,0, 9,0, 2,5 m/s after 30 minutes), creatine kinase (CK) and aspartate aminotransferase (AST) (rest and after 30 minutes, 12 and 14 hours). Preview and then the stress test bronchoscopy examinations were performed. The mean LDH showed increasing rise in blood concentration of the speed increase (0.87±1.08, 1.47±1.31 and 8.95±2.8 mmol/L) and as was regressing the year there was a decrease (6.91±3.94 and 3.58±3.49 mmol/L). The concentration of CK and AST were within normal limits at all times with average in the 30 minutes 12 and 24 hours post-test effort respectively 198,27±89,31 and 188,53±53,37, 198,67±67,56 and 205,07±41,79 and 237,80±221,91 and 202,53 ± 32,73 IU/L. On examination endoscope, pre-test effort, it was observed the presence of changes in the respiratory system in 46.66% (7/15) of horses there two cases of laryngeal hemiplegia and one dorsal displacement of the soft palate, ethmoid change, epiglottis neoplasia, osteofaringeana neoplasia and bronchial secretions. After the stress test the occurrence was 33.33% (5/15), with two cases of pulmonary hemorrhage induced by exercise grade 1 and three of serous secretions and two located in the tracheal region and bronchial region, however none of the observed changes was able to influence the performance of the animals. It was concluded that the horses of the police squad assembled Aracaju, are able to carry out patrol activities mounted, and that the stress test associated with measurement of serum levels of CK, AST and LDH are important tools for determining the fitness.
