Lameness causes significant economic losses in dairy cows. Lesions of the foot are the cause
of about 85% of all lameness in dairy cows. In addition, lameness can be localized in other
places of the locomotor system such as joints, muscles, and skin. The aim of this study was to
show the distribution of locomotor lesions in dairy cows. A total of 144 Simmental dairy
cows (36 primiparous and 108 multiparous) from 10 small dairy farms located in the Macva
district, Serbia were observed during regular hoof trimming. All cows were housed in a tiedholding
system. The clinical examination focused on all possible alternations on the observed
hooves and legs. Lesions of the horn, skin, joints, and leg injuries were noted. Of the 144
animals presenting for a hoof trim, 49 cows (34.0%) had no locomotor lesions noted. In this
study, lesions were present in 95 (66,0%) of all examined cows. Locomotor lesions of the
horn were detected in 82.4% (61/74 of cases), skin 2.7%, joints in 10.8%, and leg injuries in
4.05% of the cases in multiparous cows. Thus, lesions of the horn were detected in 61.9%
(13/21 of cases), skin 4.7%, joint in 23.8% and leg injuries in 9.5% of the cases in
primiparous cows. Our results show that lesions on the hooves are the most dominant site of
the locomotor system.Book of abstract
