This study aimed to test whether shredded cardboard is an appropriate minimum-dust bedding material for heaves-affected horses. Results of standardized in vitro measurement of airborne dust and aeroallergen concentrations of cardboard bedding were significantly lower than those of common bedding materials. Six heaves-affected horses in clinical remission after pasturing were stabled for two months on cardboard bedding and fed grass silage. Pulmonary function tests (PFT: ventilatory mechanics, arterial blood gases, airway inflammation scoring, bronchoalveolar cytology) were performed before, during and after this period and after stabling the horses in poor hygienic conditions. PFT values measured during and after the stabling period on cardboard bedding were not significantly different from those recorded after the period at pasture or from those of healthy horses, but were significantly different from those recorded in poor hygienic conditions. On basis of the in vitro and in vivo results it can be concluded that cardboard bedding, used in conjunction with low-dust forage, may be appropriate in the provision of minimum-dust management of heaves-affected horses.
本研究旨在测试碎纸板是否是适合患慢性阻塞性肺病马匹的最低扬尘垫料。对纸板垫料的空气传播灰尘和空气变应原浓度进行的标准化体外测量结果显著低于普通垫料。6匹在放牧后处于临床缓解期的患慢性阻塞性肺病马匹被安置在铺有纸板垫料的马厩中两个月，并喂食青贮草料。在此期间之前、期间和之后以及在卫生条件较差的环境中饲养马匹之后，进行了肺功能测试（PFT：通气力学、动脉血气、气道炎症评分、支气管肺泡细胞学）。在铺有纸板垫料的马厩饲养期间及之后测得的PFT值与在牧场饲养期后的记录值或健康马匹的记录值无显著差异，但与在卫生条件较差环境中饲养后的记录值有显著差异。根据体外和体内结果可以得出结论，结合使用低扬尘草料时，纸板垫料可能适合为患慢性阻塞性肺病的马匹提供最低扬尘管理。
