  1. 1AFS = age at first insemination; IFL = interval from first to last insemination; CR = conception rate at first insemination; AIS = number of inseminations per conception; NRR56 = non-return rate at 56 d after first insemination; ICF = interval from calving to first insemination; DO = days open. For the traits expressed in both heifers and cows, a suffixes h (for heifers) or c (for cows) was attached to the trait abbreviations.
  2. 2The number of animals.
  3. 3The average reliability of pseudo phenotypes (yield deviation for cows, daughter yield deviation for Chinese bulls and de-regressed proof for Nordic bulls).
