Genomic breeding values (GEBV) were estimated for the three cumulative traits of claw disease (NP): infectious claw disease (IP), claw disorder (PP) and total claw disease (CNP), as well as lameness (K) and CNP+K. Disease data from the Diary of Diseases from 2018 to 2020 were used. The reference genomic population included 25 458 individuals, including young genomic animals: young bulls without progeny (303 animals) and heifers without records (12 286 animals). The lowest average genomic reliability was found in K (18 %). Genomic bulls with daughters in the datasets achieved the highest reliability average of all categories evaluated, max 85%. The number of daughters of the bull in the dataset turned out to be a factor in increasing GEBV’s reliability. For genomic heifers without records, the maximum reliability was 38 % to 45 %. Finally, we want to emphasise the positive influence of genomic estimation on the reliability of GEPH, especially in young animals without records.
