The association of hoof lesions at claw trimming with test-day milk yield in Danish Holsteins
In a cross-sectional study, performed between October 2002 and April 2003 on 55 Danish
dairy herds with 6161 predominantly Holstein Friesian cows the prevalence of 9 hoof lesions
was determined. All test-day yields (TDY) of kg energy corrected milk (ECM) in the lactation
of diagnosis were recorded. For the purpose of including hoof lesions in a decision support
model an attempt was made to aggregate the lesions into digital dermatitis (DD), other
interdigital diseases (OID, infectious diseases other than DD) and hoof horn diseases (HHD …
