Farm-Level Risk Factors for Lameness in 659 German Dairy Herds Kept in Loose Housing Systems.

Six hundred fifty-nine farms in three regions of Germany (North: = 240, East: = 247, and South: = 172) were included in the study, which aims at determining the association of management-related risk factors with farm-level lameness in German dairy herds. For each risk factor, a generalised linear regression model with negative binomial distribution and logit link was built. Results showed that cows housed in deep-bedded cubicles had a lower risk of being lame than cows housed in other cubicle types.

The relationship between lameness prevalence and pasture access in 659 dairy herds in Germany.

Lameness in dairy cows is an expression of pain most likely originating from a claw disorder, causing impaired animal wellbeing and substantial economic losses for farmers. The aim of this study was to investigate the effects of access to pasture, time spent on pasture, and season on farm level lameness prevalence. The survey was part of a cross-sectional observational study, in which farms in three regions of Germany (North, East and South) were visited by study veterinarians.
