For 2018 the overall cow and heifer pregnancy rate was 95.1%. Over 90% of the cows conceived in their first heat cycle, despite the brutally high temperature and humidity levels during the breeding season (mid-July through August). Cows at Lukefahr Ranch are not pampered; if they do not adapt they are culled. In 2017 the average feed cost per cow was $4.04. No hay was fed during the winter.
