A bull sale is an exhilarating time for ranchers. The auctioneer can be heard chanting dollar amounts while a bull displays his quality attributes in an auction ring. The energy of the air permeates a breeder’s anticipation of a once-a-year payday and pride in showing their best bulls. Cattle producers anxiously await the opportunity to bid on their picks of sires for their herds. Locals and out-of-town ranchers share the same sentiments and traditions of building a quality cattle program on their ranch operations.
Like with many important purchases, education and preparation are key to obtaining a bull for buyers with traits that are their top priorities. Clearly define a budget before the sale starts. Closely look over the bull sale catalog and plan to look at the animals before they hit the auction ring. Review the EPDs (Expected Progeny Differences) to see what bulls match what you’re looking for in your program. Programs differ in that one ranch may be focused on breeding cattle whereas another may be looking to sell off calves to the feedlot.
There are a wide variety of EPDs but the most typical metrics in a sale catalog include birth and weaning weights, physical appearance, and performance of the animal and its relatives. You can consider the table below for other commonly used EPDs. (Table courtesy of the University of Montana)
Commonly used EPDs:
|Unit of Measurement
|Usefulness of EPD
|Calving Ease Direct
|Difference in percentage of unassisted births when bred to first-calf
|A higher CED value indicates greater calving ease when bred to first-calf heifers.
|Indicates a sire’s ability to transmit birth weight to his progeny, a lower value indicates calves that will be lighter at birth.
|Indicates a sire’s ability to transmit weaning growth to his progeny, a higher value indicates calves that will be heavier at weaning.
|Indicates the additional pounds of calf weaned by a bull’s daughters due to milk production. As milk increases, so does a cow’s nutritional requirements.
|Indicates a sire’s ability to transmit yearling weight to his progeny. As yearling weight increases so does mature cow weight.
|Predicts the difference in ribeye size of a sire’s progeny compared to progeny of other sires.
|Fraction of the difference in USDA marbling score
|Indicates a sire’s ability to transmit marbling ability to his progeny. A greater value indicates greater marbling potential in offspring.
|Predicts the difference in transmitting scrotal size compared to other sires. A larger scrotal size is positively correlated with the fertility of the bull’s offspring.
The EPDs are usually included in the sale catalog. Should a buyer have any questions, they can always contact a breeder before the sale.
