Background: The approach to respiratory diseases in donkeys is similar to that for horses, nevertheless bronchoalveolar fluid (BALF) and tracheal wash (TW) cytology in this species have been described only a few times in the literature.
Aim: To describe BALF cytological findings in a cohort of 24 healthy Amiata donkeys.
Methods: Bronchoalveolar lavage (BAL) was performed under standing sedation with a large animal where the broncho-alveolar lavage catheter passed blindly through the nasal passage into the trachea.
Results: The total nucleated cell count (TNCC) of the BALF was found similar to that already described in healthy horses and donkeys. No differences in the differential count were observed according to age and sex. A decreased macrophage percentage and an increased eosinophil percentage was observed in our donkey population when compared to the existing reference range for horses.
Conclusions: The reference intervals for BAL cytology in donkeys may be significantly different for those referred for horses.
Keywords: Donkey, BAL, Respiratory, Cytology.
