IntroductionAsthma is common in many equine populations and airborne particles are recognised as potential predisposing factors in disease pathogenesis. The aim of our study is to investigate effects of two bedding materials, peat and wood shavings on equine airway health. Materials and methods32 clinically healthy adult riding school horses were stalled on different bedding materials for 35 consecutive days (peat – wood shavings – peat) during September – December 2018. The horses remained in the same stalls and the feeding, exercise or management did not change during the study period. Clinical examination was performed and tracheal wash (TW) and bronchoalveolar lavage fluid (BALF) samples were obtained for cytological analyses at the end of each period. TW and BALF neutrophil percentages were compared with repeated samples T-Test using horses as their own controls. Significance was set at P < 0.05. ResultsThe horses remained healthy during the study period. TW neutrophil percentage was higher after the shavings period (mean ± SD; 32.8 ± 25.0) compared to first (17.2 ± 15.9; P = 0.009) or second peat period (13.1 ± 15.9; P < 0.001). BALF neutrophil percentage was lower after the second peat period (1.6 ± 1.1) compared to the shavings period (3.4 ± 3.1; P = 0.002) or first peat period (2.7 ± 2.2; P = 0.008).ConclusionsThese preliminary results suggest that wood shavings increase airway neutrophilia detected in tracheal secretions compared to peat bedding. The result might be helpful in choosing bedding material for horses with equine asthma.
