EPD's question

[charangusman08]

Say you have a charolais bull with:

Birth weight- 2.3
Wiening weight- 34
Year weight- 60

Would that be the same as a black angus with the same EPD? I mean does it change with every breed or is it the same for every breed?

The breds are different, so a Angus epd would only be comparing Angus bulls to each other. This might help you:

No. It changes with every breed. Comparing EPDs across breeds will just mess up the whole analysis of EPDs anyway, since EPDs are comparing animals of the same breed, sex, environment, etc. with each other. Or something to that effect.

U of Florida has one of the best ways of explaining EPDs IMHO: http://edis.ifas.ufl.edu/pdffiles/AN/AN16400.pdf

No. As others have said each breed has their own set of EPDs. They're based on data reported by breeders and each one may have a different base year.

Here's a link to the MARC across breed EPDS. They allow you to compare breeds:
