Genetics

Competitiveness and profitability of any industry will be strong when a product is produced and marketed that is of value to the consumer. The same is true with Tennessee's cow-calf industry.

To remain competitive and profitable, a quality product, a feeder calf, must be produced to meet the needs of the remaining sectors of the beef industry and that results in a food product satisfying consumer demand. Cow-calf producers' challenges and responsibilities are to put together cowherds with the genetic makeup to maintain profitability of the entire beef industry.

Technologies and information are available that cow-calf producers can use to meet this challenge of making genetic improvements or directional changes in measurable, economically important traits.

           

 


Across-Breed EPD Adjustments
Most beef breed associations publish EPDs either on an annual, biannual or weekly basis. These EPDs are used to predict expected differences in performance of future progeny between two or more bulls within their same breed for performance traits.

Color Patterns in Beef Cattle
This fact sheet explains how color is inherited in cattle. Knowledge of the inheritance of color allows breeders to predict the color patterns to expect among calves when using different breeds in a cross-breeding program.

What Should Be Considered in Bull Selection
Outlines considerations for selecting sires, including type of breed, saving replacement heifers, increasing weaning weight and frame size, concerns about temperament, and where to find bulls.

Angus Cow Longevity Estimates and Relationship to Production Traits
Sire summaries are produced and published twice a year by breed associations to provide up to date genetic evaluations on progeny of proven sires within their breeds. The sire summary formats may vary between breeds.

EPDs and Accuracy
Expected Progeny Differences (EPDs) are reported by most major breed associations and are a means of estimating an individual's genetic value as a parent for a particular trait. The EPD is a means of predicting differences between progeny performance in a particular trait between prospective animals.
