A study on claw disorders’ infl uence on milk production was performed during one year on 226 Simmental loose-reared cows. The first trial group
included 42, the second 37, and the third 34 cows, with claw changes observed in the first hundred days of lactation, between days 101 and 200,
between days 201 and 305, respectively. The control group included 113 cows with no observed changes. Lameness intensity was assessed once a
week. Milk yield data were collected three weeks before, in the week of treatment of claws and three weeks afterwards. There were significantly more
cows with lameness in the third group than in the other two groups, as well as the most cows with one aff ected limb in the first hundred days of the
lactation (P<0.05). Significantly fewer cows with two aff ected limbs were present in the first group. In the second group, more cows were observed
with two aff ected limbs than in the first group (P<0.05). In the third group, more cows with three or four aff ected... limbs were noticed than in the
other groups. The most common claw disorders were: solar ulcer, laminitis, dermatitis digitalis and overgrown claws. Cows whose claws were aff ected
between days 101 and 200 of lactation period produced 231 kg less milk than those of the control group; cows whose claws were aff ected in the last
third of lactation produced 26 kg less milk. Nevertheless, no significant diff erences were found between milk yields of the control and trial groups
(P>0.05). Cows aff ected in the first third of lactation produced less milk (324 kg) than both healthy and cows with claw changes manifested in later
stages of lactation. Obtained data confirm that claw disorders may aff ect dairy production.
