Lameness is an important farm-related disorder

• Economic damage (Huxley, 2013, Dolecheck and Bewley, 2018; Edwardis et al., 2022)

• reduced production and fertility

• costs of treatment

• premature culling/euthanasia, accounting for 25% of deaths of all dairy cows (Thomsen, 2022)

• Animal welfare. (Bruijnis et al., 2011)

Prevalence of lameness is over 30 years estimated to be around 20- 30% (Thomsen et al., 2023).

The objective of this study:

A query was performed:

A structured questionnaire

Locomotion score according to Sprecher et al (1997), 1-5 scale Statistics

Only practitioners consider udder health more important than claw health, in contrast to claw trimmers and feeding advisors. Suboptimal nutrition is considered as a factor of great importance by:

• 55% of dairy practitioners
