Genetic evaluation of claw health in Denmark, Finland and Sweden
A Claw Health Index (CHI) was developed and included in the Nordic Total Merit Index (NTM). The index combined information from a multiple trait evaluation that contained 7 claw trimming traits in each of the first 3 lactations. Genetic parameters for the 21 traits were estimated for Holstein and Red Dairy Cattle (RDC). Heritabilities ranged from 0.01 to 0.07 for both breeds. Correlations between CHI and fitness indices and NTM were all favourable for selection.
