I think one of the outstanding things we've used in the last number of years is genomics. Instead of having to wait for the standard five years to see if an animal actually produces what her genetic potential is, through genomics we can actually scrape a few cells off an embryo and know what the potential might be coming up. Through research we've been able to verify that those numbers are exact and correct. So you move the generation along very quickly and that has helped tremendously.
Other than that, frozen semen—selective parenthood, as I like to call it on our farm—has tremendously helped, because we only use the very best bulls and we only keep the very best dams, so that moves things along quite quickly. We don't keep just a cleanup bull in the barnyard anymore. We know what everything is and we keep the records. All those things are vitally important to us.
