Analysis of Tracheal Secretion in Healthy Horses Undergoing a Vaquejada Simulation Test

This study aimed to evaluate the occurrence of EIPH in vaquejada horses via endoscopy and tra-cheal lavage and citology. We used eight Quarter-mile horses that usually perform at vaquejadas. Clinical examination was carried out before the race. After the race, endoscopy and tracheal la-vage with 20 ml of saline via the service channel of the endoscope were performed. The samples were sent to the laboratory for processing and confection of the slides. Of the eight horses (four pull and four helper horses), six had hemosiderophages in their tracheal aspirates, confirming the existence of pulmonary hemorrhage after exercise. No difference was observed between the ana-lyzed parameters between the two groups of vaquejada horses (P> 0.05). Tracheal lavage and endoscopy can be used for evaluating this important disease in animal athletes
