RESUMO

A retrospective study was carried out with the objective to identify risk factors and the incidence of training failure among Thoroughbred racehorses. Two hundred fifteen Thoroughbreds had been evaluated, in the period of January 2001 to December 2003, at Rio de Janeiro-RJ. All the horses had been displayed to the same conditions of handling, feeding and athletical training. The veterinary evaluation of the horses was carried through daily and the clinical notations, protocol training beyond the campaign of the horses, had been registered individually being later enclosed in the management veterinarian software. The complementary examinations had been image diagnosis, laboratorial clinical analysis and, when necessary, the microbiological examination. The clinical causes or for veterinary intervention of interruption in the training of the equines had been categorized the relative data to the causes of interruptions of horses training had been submitted initially to the descriptive analysis. The independent variables had been evaluated individually in relation to the association with interruptions of training using contingency tables and Chi-Square test. A total of 351 cases of training failure was recorded, 54,7% due lameness, 11,1% due to respiratory infections, 16,5% due to hemoparasitosis and 17,7% due to other causes. The rate for fillies was always lower than for colts. Incidence of lameness among horses increased to the beginning of more intensive training. The incidence of respiratory infections never exceeded 18% and was higher in the group of 2-years-old. It can be concluded that the lameness was the most important of the causes of training failure among Thoroughbred racehorses and its incidence with age is directly proportional to the increase of the training intensity.
