Are we too dependent on EPD's?

[QUOTE="Rmc, post: 1727164, member: 39072"] Why do I think the epd # are made up ? Simple to answer. Because they are. They are the result of a mathematical formula that is not based on genetics. They do not accurately predict the genetic potential across generations or across different environments. And are very easily manipulated. If you took four clones of the same animal and sent them to four different regions of the us do you think the epds would be the same ? Do you think an animal raised in the Midwest and was feed huge amounts of creep would have the same epds as one that was raised in the west on a BLM permit with no creep feed? They should if they are identical genetically. But we all know they wouldn’t even have close to the same epds. Epds are too easily manipulated and are nothing more than a tool to put more money in certain breeders pockets and are not based on genetics. [/QUOTE]
