Results from the project documented the Hereford efficiency advantage with a 7 percent increase in conception rate along with improved feed efficiency and average daily gain. Utilizing the Circle A data, economist Vern Pierce developed an economic model that projected that over a 10-year period, using Hereford bulls on Angus-based females would add $514 net over the life of a cow or approximately $51 per cow per year to a rancher’s bottom line.
Now, six years later, Circle A is still using Hereford genetics and having great success. Circle A’s Nick Hammett says that since the completion of the research project, the ranch has purchased four Hereford bulls that it is utilizing natural service and collecting for artificial insemination.
The Hereford bulls are mated to Angus cows, and the resulting heifers are highly sought-after. Each fall Circle A Ranch offers bred replacement heifers in its production sale, and in recent years, the Hereford-sired heifers have been topping the sale.
Hammett says the Circle A Ranch staff plans to continue using Hereford bulls
“We will keep using Hereford genetics," he says. "If they keep selling like this, it’s a win-win for us. We harvest all the steer progeny, and the F1 females sell really well.”
