Mucociliary clearance rate constants for ten calves were obtained using Technetium 99m-sulphur colloid complex. The mean rate constant measured at the lung for all calves was 0.012 (+/- 0.009) min-1 (half-life 58 minutes). The clearance rate constants obtained from measurements made at the larynx were higher (0.02 +/- 0.007 min-1), although not significantly higher, than those determined from measurements taken at the lung. The constants can be used to predict the particle burden on the lungs of calves kept under husbandry systems of varying air hygiene.
使用锝99m-硫胶体复合物获得了10头小牛的黏液纤毛清除率常数。所有小牛在肺部测得的平均速率常数为0.012（±0.009）分钟-1（半衰期58分钟）。从喉部测量获得的清除率常数（0.02±0.007分钟-1）高于在肺部测量确定的常数，尽管差异不显著。这些常数可用于预测在不同空气卫生饲养系统下饲养的小牛肺部的颗粒负荷。
