We believe that good maternal genetics can be profitable in the feed lot. You do not have give up the maternal traits of the Angus breed to get the carcass traits that so many breeders are chasing. We, at Big Rok, are getting actual data to prove this. In the past year, one of our bull customers, that feeds his own calves right here in Minnesota, has given us the following kill data. Big Rok bulls sired all these calves and the majority of the cows were out of Big Rok genetics.

This is REAL carcass data!!

We will continue to collect actual carcass data on our calves and as many offspring of our genetics as possible. We believe actual kill data is better than ultrasound data, so we are going to continue in that direction. As you can see, Good Maternal genetics ARE Carcass genetics. You don't have to give up one to get the other. We will continue to collect actual carcass data on our calves and as many offspring of our genetics as possible.
