摘要：

The objective of this study was to identify cow-level factors associated with poor body hygiene. Cows (n = 2644) from 68 commercial dairy herds (free-stall (n = 43); tie-stall (n = 25)) in Ontario, Canada were enrolled. Cows were hygiene scored on each of three visits (7 days apart). Older cows were at higher risk of having a dirty udder and dirty upper legs and flanks in free-stall barns and younger cows were at higher risk of having dirty upper legs and flanks in tie-stall barns. Higher days in milk was associated with better hygiene for cows housed in both free-stall and tie-stall barns.
