Sire Traits vs. DamTraits Dam traits– traitsthatcome from the maternalfigure.Thesetraitsare often relatedto raisinghealthyoffspring.Ex.Fertility,milkproduction,calving ease, care. Sire traits– traitsthatcome from the paternalfigure.Thesetraitsare relatedto growth,size,andmuscling.Ex.Rate ofgain,feed efficiency, ribeye area. Bothsets oftraitsrelateto the breedas a whole.Theyare notto be confusedwith thegender ofthe individual.
