Using EPDs in Selection Livestock Production Using Genetics in Livestock Production (c) (6)(B)

First, look at breeding values: Phenotype – The appearance of an animal. Genotype – What genes are present and how they are combined.

How are Breeding Values Reported? (EPD) Expected Progeny Difference – A measurement of genetic potential based on the performance of relatives. (ACC) Accuracy is an important term used in understanding EPDs. It is a measure of expected change in the EPD as additional young are born to the sire. A high accuracy value is better as the chances of the EPD being correct rise.

How are Breeding Values Reported? Common EPDs: Performance-based, Carcass-based, and Ultrasound. Performance-based EPDs – Are based on a measurement of how well the bull’s offspring perform. Examples of performance-based EPDs are birth weight, weaning weight, milk and yearling weight. Carcass-based – Are based on how well the bull’s offspring have performed on the rail. Examples of carcass-based EPDs are Rib-eye Area, Fat (Outer), Retail Product, and % Intramuscular Fat. Ultrasound EPDs – Done from an ultrasound of the actual bull. Examples of ultrasound EP’s are Rib-eye Area, Fat (Outer), and % Retail Product.

How to Compare EPDs BW WW Milk YW Marb REA FAT %IMF RE %RP Bull A -0.5 +61 +15 +111 +.20 +.19 +.017 +.50 +.22 +.004 +.28 Bull B +0.1 +50 +21 +51 +.44 +.26 +.66 -.046 EPDs can be useful for comparison. Look at the Select Sires Explanation for how EPDs are measured. For example Birth Weight is in pounds. How much more will Bull B weigh at birth than Bull A? Answer: .6 pounds. How much more will bull A weigh at weaning than Bull B? Answer: 11 pounds Which bull would be a better bull for heifers? Answer: Both would be fine. But smaller calves would come from A. Which bull has a bigger Rib-eye Area? Answer: Bull B

Selection of Cows Culling – Cows should be culled from the herd based on the productivity of their calves. Evaluation – Cows should be culled based on evaluation of the udders, eyes, skeleton and teeth.

Selection of Heifers Try to select heifers that will conceive early in the breeding season, calve easily, produce a good supply of milk, wean a heavy calf, make a desirable genetic contribution to your cow herd, and have calves with desirable carcass traits.
