All reports from the August 2019 Genetic Update are now available at usguernsey.com/pedigree-system.
Along with the updated genetic information, Guernsey performance pedigrees now sport several new traits! The traits added are Livability (LIV), Heifer Conception Rate (HCR), Cow Conception Rate (CCR), Gestation Length (GL), and Expected Future Calving (EFC). These traits will be published for all animals with genetic indexes alongside their reliability %. See the photo for an example, and the links below for more information:

HCR: Heifer conception rate
A virgin heifer’s ability to conceive – defined as the percentage of inseminated heifers that become pregnant at each service. An HCR of 1.0 implies that daughters of this bull are 1% more likely to become pregnant as a heifer than daughters of a bull with an evaluation of 0.0
CCR: Cow conception rate
A lactating cow’s ability to conceive – defined as the percentage of inseminated cows that become pregnant at each service. A bull’s CCR of 1.0 implies that daughters of this bull are 1% more likely to become pregnant during that lactation than daughters of a bull with an evaluation of 0.0.
