Obstruções do trato respiratório inferior
apresentam grande impacto no potencial atlético de
cavalos de corrida. Doença Inflamatória das Vias
Aéreas (DIVA) constitui achado comum em cavalos
de corrida jovens. Esse estudo testou a hipótese
de que a inflamação do trato respiratório inferior
poderia iniciar ainda na vida no haras. Sete diferentes
haras foram visitados, e 119 potros sobreano
foram investigados. As vias aéreas inferiores foram
avaliadas através de exame clÃnico e endoscópico,
e citologia do aspirado traqueal. Entre os potros
considerados clinicamente saudáveis, 90,76% evidenciaram
muco traqueo-bronquial e os perfis citológicos
evidenciaram reação inflamatória presente.
A presente investigação confirma a presença de
inflamação pulmonar em potros PSI antes do inÃcio
do treinamento, representando um risco potencial Ã
capacidade atlética futura.
Lower respiratory airway obstruction
has a major impact in racehorse athletic potential.
Inflammatory Airway Disease (IAD) is a common
finding in young racehorses. This study tested the
hypothesis that lower airway inflammation could
initiate in farm life. Seven different breeding farms
were visited, and 119 yearlings were investigated.
Lower airways were evaluated by clinical
examination, endoscopy and cytology of the tracheal
aspirate. From those yearlings considered clinically
healthy, 90,76% evidenced tracheobronchial mucus
and some showing cytological profile of inflammatory
reaction. Then, the present investigation confirms
the occurrence of inflammatory condition of the
lower respiratory airways in thoroughbred yearlings
before training has commenced, representing a
potential risk for the future athletic performance in
young racehorses.
