What is the average EPD for Angus?
For instance, the average Yearling EPD of +83 for Angus compared to +42 for Charolais does not mean the Angus breed is 41 pounds heavier than Charolais.
How are Angus EPDs calculated?
For a given trait, EPD values are calculated based on data submitted by producers to breed associations from an animal’s actual performance, performance of progeny, performance of other relatives, and genomic data (DNA analysis, if available).
What are Angus EPDs?
Expected Progeny Difference (EPD) , is the prediction of how future progeny of each animal are expected to perform relative to the progeny of other animals listed in the database. EPDs are expressed in units of measure for the trait, plus or minus.
What does CED mean in cattle EPDs?
Calving Ease Direct
So when calving ease is important consider the following EPDs: Calving Ease Direct (CED), is expressed as a difference in percentage of unassisted births, with a higher value indicating greater calving ease in first-calf heifers.
What is a good weaning weight EPD?
According to the American Angus Association, the average weaning weight EPD across the breed has increased from -7 in 1972, to +18 in 1990, +31 in 2000, +45 in 2010, and +52 in 2014. Many purebred Angus producers are weaning calves that are 800 lbs, and some even over 1000 lbs (calculated to 205 days).
What is considered low birth weight in cattle?
Table 5
Energy level of ration | Birth weight | Dystocia |
---|---|---|
Low (10.8 pounds TDN) | 58.0 pounds | 26 percent |
Medium (13.7 pounds TDN) | 61.5 pounds | 17 percent |
High (17.0 pounds TDN) | 63.9 pounds | 18 percent |
What is the average weaning weight for Angus cattle?
The average weaning weight per cow exposed for all cows in the study was 341 pounds. The average cumulative weaning weight per cow over her lifetime in the herd was 1,220 pounds. Angus-Brahman-Hereford three- breed rotation cows had the highest weaning weight per cow exposed at 414 pounds.
What is the average weight of a Angus cattle?
Most Black Angus cattle are medium to large, naturally polled with large muscle content. Average body weight for bulls is about 1,870 pounds, while cows weigh in at 1,200.
What is the average birth weight for Angus cattle?
78.7 pounds
Table 3
Breed of sire | Calving difficulty | Birth weight |
---|---|---|
Hereford and Angus | 2.9 percent | 78.7 pounds |
Jersey | 2.9 percent | 68.6 pounds |
Red Poll | 3.7 percent | 78.7 pounds |
Tarentaise | 6.0 percent | 82.7 pounds |
How does the American Gelbvieh Association predict EPD?
The American Gelbvieh Association uses all available information to predict an animal’s EPD. This information includes: individual performance, pedigree, progeny and grand progeny performance, plus available genomic information.
What does EPD mean for weaning weight of Bull?
EPDs are measured in the units of the trait, and show the differences in performance between animals. For example, if Bull A has a weaning weight EPD of 80, and Bull B in the same herd has a weaning weight EPD of 70, then bull A’s calves would be expected to be 10 pounds heavier at weaning than those of bull B.
How often should an EPD be updated for a three year old bull?
For example, a three year old bull with 90 calves would have EPDs of higher accuracy than a virgin yearling bull. Accuracies range from zero to one, with numbers closer to one being more accurate. EPD breed averages updated four times a year.
Where can I find information on GE EPDs?
Phenotypes such as birth weight, weaning weight, and calving ease are still needed to make the equation we use to predict GE EPDs as accurate as possible. For more information on GE EPDs, call the office at 303-465-2333. Bourdon, 2000.
