The aim of this study was to evaluate the influence of claw disorders on claw formation, production and reproduction performance of Holstein and Slovak Spotted dairy cows. Claw formation after functional trimming was evaluated by measurement of claw angle, claw length, heel index, claw height, diagonal and claw width. Incidence of interdigital dermatitis and heel erosion, digital dermatitis were observed. Separately was observed the incidence of sole ulcers with the progress of diseases. Measurements were carried out in spring and in autumn. Holstein dairy cows (n = 101) with production 11,874.77 kg of milk, 3.94% of fat and 3.34% of protein and Slovak Spotted cows (n = 101) with production 5,834.25 kg of milk, 4.44% of fat and 3.59% of protein were included into study. Holstein and Slovak Spotted dairy cows affected with claw diseases produced on the first lactations 553.67, resp. 838.71 kg of milk more than average production of observed groups. On the second and higher lactations dairy cows of Holstein and Slovak Spotted breed affected with claw diseases produced 734.3, resp. 1,118.3 kg of milk less than healthy dairy cows. The occurrence of digital dermatitis was 5.77% and 4.85% in Holstein, resp. in Slovak Spotted breed. Age at the first calving with claw defects was shorter of 24.45 days and the calving interval was longer of 18.52 days in comparison to cows without claw disorders in Holstein breed. Difference in age at first calving was minimal with value 1.85 days on behalf of healthy cows and on the other hand cows with claw defects had shorter calving interval by 4.97 days than healthy cows in Slovak Spotted breed. Statistically significant differences in claws formation were observed in both breeds according to the claw trimming season.
