This study was aimed at assessing the genetic parameters for fertility-related traits, comparing the interval from calving to first insemination (ICF) to physical activity traits, especially days from calving to first high activity, DFHA. Data from commercial Holstein herds included insemination dates of 11,363 cows for ICF. The activity traits were derived from electronic activity tags for 3533 Holstein cows. Estimates of heritability were 0.05 for ICF and 0.15 for DFHA. The genetic correlation between ICF and DFHA was strong (0.92). The high heritability estimate and the strong genetic correlation between ICF and DFHA suggest that genetic gain in ICF can be improved by including DFHA as a supplementary trait in the genetic evaluation of female fertility
