[QUOTE="Jafruech, post: 1683114, member: 24025"] EPDs are a great tool when used properly...and when the inputs for them are done by people who do it the right way. DOC ACC is only as good as the people who did the scoring. If the inputs are junk...then the EPDs will be junk. I love genetics and I won't nerd out too much on the issue...but there's a reason why it is "estimated." It gives you probabilities not certainty. Nothing is 100% heritable, and even if all the inputs are done perfectly...it's going to give you reliable probabilities...but still only probabilities all the same. I'm one of the outliers who loves math, genetics, etc...and I enjoy using that knowledge to shape genotypes and phenotypes in my herd. I think it is a useful tool, but it can be misused/abused, etc. It's not for everyone, and not everyone enjoys the things I do. Any idiot can try and do the BIF steps to measure DOC...but that doesn't mean they will do it well. Which comes down to a breeder issue, not an EPD issue. There's good breeders out there who go above and beyond and provide disposition scores in addition to EPDs (and a lot of other scores in addition)...and use genetics and practices that are reflected in the EPDs. I will say the EPDs from my bulls and their progeny have been as advertised...but they also had a lot more evaluation on them than was "required." The Docc score and test is a good tool to measure it quickly...and it exists for a reason as a tool of measurement and works when done properly...the last 2 words there being key. It's a tool...and it's only as good as the people using it. [/QUOTE]
