The computer program that creates EPDs is a sophisticated, high level mathmatical program.
Oh that's rich. That programed into peoples head what to tell others who want to dig deep rather than except what they have been given? Is this kind of like Dumbing of America? I got the same response from the AAA. Computer didn't just get this equation from the hard drive by itself, humans need to make the equation.
Hahahahaha that's funny. :roll:Not to be rude, but you don't even seem to understand what EPDs do.
How could you expect to understand the mathmatical formula that they use to create EPDs? Every breed association uses much the same formula; call your other breed association and ask them. Maybe they'll be nicer than the AAA people.
How can you act like you know all about the EPD's when you can not give nor do the foundations/program that go into making a EPD, but only give the final conclusion numbers of what they might mean. It doesn't take even a kindergardener to figure out that 80 is higher than 60. And that the lower the BW EPD the chances are that you may get a lighter calf if your cow is a bigger birth weight than the bull. Just because I don't like EPD's and don't reley on them doesn't mean I can not read and examine EPD's and look way beyond what other do. And yes I have used them in advertising and promoting what's he's so good in with in the breed. Have to appeal to the buyers on what they have been washed in to thinking is wonderful. Only those that came up with and use the EPD equation know what it entails.
I'd take them a copy of MARC's across breeds EPDs. That will give a basis for comparing Angus EPDs with other breeds. But be warned, you might not like the result.
MARC only has a few to cross with as you know, since you know your EPD's .
The Angus Association took all the BW, WW, YW's reported to the Association in 1976 (I think), averaged them, and called that zero when they started EPDs. But that doesn't mean anything; EPDs have been adjusted since then. The program that creates EPDs has been improved.
Am I correct in the AAA base is now between 70 and 77?
Explain to the bull buyer that EPDs won't tell him what a calf will wean at. EPDs will never, ever tell you what something will weigh. They can't. If you breed a Charolais cow and a Jersey cow to the same bull, would you expect the calf to weigh he same at birth, weaning or yearling? The bull is only half the calf. You may think EPDs are no good, but, believe me, more and more cattlemen are recognizing their value.
More and more producers are not following EPD's also, those that have been let down. Depends who you talk with. Oh no I'm not talking about breeding x breed bull to y breed cow on what a producer wants to know. That can't happen. I'm talking about a producer buying X breed versus
Y breed of bull. The realistic scenario. A producer wants the best bull he can get regardless of breed. That's why there needs to be a total across breeds EPD/APD.
I hate to break it to you, but you're in the minority if you're mystifed about EPDs. Every breed association probably has a brochure that explains how their EPDs were created. Have you taken the time to read them? The Angus brochure that I prefer to hand out to bull customers who are not so comfortable with EPDs is called "Bull Buying Stategies to Improve your Herd." I'll look for it online and post a link for you. But you have to read it and try to understand what it says.
Frankie you yourself can't give me a equation nor the across breeds equivalent then you are mystified also. If you know the equation please get that to me then I will know that you know all there is to know about EPD's . If you would have read Yes I read the blah blah the AAA has and
it's just lots of words that don't tell me what I really want to know. Yeah I had that little book of bull buying they sent. That didn't tell me anything that I wanted know - the equation! It's like reading a government study that leaves all the important things out but has a lot written to think
the people are getting something worth while. Some of us want to know the nitty gritty not the fluff of it's a high level mathematical program and a- it's simple 80 is higher than 60. And if you want to improve this and that get this, but watch out not to get to high of this trait EPD of it will off set this. Well DUH.
CA? Chi-Angus? If so, you're getting hybrid vigor with that crossbred animal that you don't get with Angus. And you haven't identified what "high" YW means.
Yeah I'm getting traits that each doesn't have, and? I have no beef against the Angus breed it's self. If I did I wouldn't be using them. But improvement on them yes. It's common knowledge that the original characteristics of Continentals in general have more muscle, lower rib fat and fat and higher weight and low marbling, and that the original characteristic of British in general have higher marbling, higher rib fat and fat, lower muscling, and lower weight. So gee what happens when you put traits together through lineages and selection. An animal that's muscle, tenderness, marbling, weight, and low waste fat. CA is 2nd for the marbling gene. Why do I say original of Continental and British. Because we all know that there's been breed dipping in most all the
breeds that will call purebred. Lets see lets say the top 20% of breed is the start of the higher EPD which is about 80 and a couple of point higher at top 15% for a non parent and parent bull the last time I looked last spring. If you are wondering an EPD is not assigned to an Angus or the
offspring resulting from a CA bull/cow coming into the ACA until there is sufficient data on the future offsprings.
Now you're ranting. I consider myself a better than average Angus breeder, but know dozens just like me and I'm not at all concerned about Angus not having the highest EPD numbers. I'll bold this for you: There are no good or bad EPDs. Some people consider a milk EPD of 15 bad; personally, a cow with that works fine on my grass based program. If you're breeding Continental heifers, you might want a BW EPD of -2. Since I know the EPDs on my Angus, I can use bigger BW EPDs which usually correlate with more muscle and heavier WW and YW. EPDs are not a magic wand. They are a tool for Angus breeders to use. I'll bold this one, too: If other breed associations want reliable EPDs, get to work reporting data.
Ranting? Because things should be able to be put in black and white no matter what breed they are. Show what animal and line is better than others in different breeds. Some how you are sticking to just one breed EPD's. I don't care about one breeds EPD's. But I want true across
breeds information. I'm glad you strive to be good. Everyone should. But you tell me how I'm going to differentiate between breeds by just using your EPD alone? Can't. Have to use actual weights and ultrasound info through lineages. Unless the EPD's are consistent in a number of
herd mates. Milk EPD doesn't bother me. I've seen 5 and 7's grow good. BW is the only EPD that I will even go by. I've heard the phrase
there's no good or bad animal, so gee lets breed them up, mass produce. Yeah it's suppose to be the combination of dam and sire to get what you want. Hell if she/he is that bad sell her/him. Don't use it as stockseed as some do just because it has good lines in there.
Interesting. I've found that the commercial cattlemen who know the most about EPDs tend to be those actually making their living in ranching. They've embraced them as a tool to help improve their bottom line. The smaller, part time breeders who can't/won't pay more than $1200 for a bull are less interested in learning about them.
So what pray tell is a smaller breeder in your eyes? Tell you what try telling those breeders who have 400 plus cows that they are part time breeders and by relying on weights and ultrasounds of that line of bull and what their results were when they wean and slaughter that they are all washed up because they don't worship EPD's. I see more rich, got to fit in, with the "right" crowd" type people swarm over EPD's.
Your comment that the higher EPD cattle let you down is not logical or likely. Cattlemen do want hard facts. And the hard fact is that EPDs are not a silver bullet. There are no silver bullets.
Ok do you have any idea that you are contradicting yourself ? So higher EPD cattle will live up to what the EPD says, god no it just can't ever be wrong, but oh wait a minute EPD's can't be trusted totally so that high EPD bull you bought might not be as good a what the EPD says. Yeah
so were back to a crap shoot again on reading EPD's. Oh yes as long as high dollar bull has tons of offspring his accuracy will be just wonderful and his EPD's will change. And of course that high dollar bull's calves will all be in an area that will result heavier weights. Have to promote how awesome he is. That's in any breed. But will be far different than if high dollar bull's offspring were born and raised in the dessert conditions. A bull that is just as good if not better hasn't been proven for 2 generations because he had far less offspring, thus EPD numbers haven't changed and the accuracy is low and he just isn't a bull that is up for contention. Oh by the way it is very logical and is not only likely it happens. Not all of us can live in areas where cattle have grass on very little acreage. Thus a bull who looks good on paper with high EPD's who's offspring were also raised in good conditions make him a wow bull, but he now has
offspring in arid tough conditions, because the producer looked at the EPD's and thought that's what he needs to increase weight in his conditions so either AI'd him or bought a son(s), but gets calves that do worse than the bulls he bought from a seed producer who had similar conditions as his. What a great way for the big shots to get bigger and the ones that are really trying to improve don't get noticed. I went through a pen a Angus Bulls that was great looking from one breeder. There sale was the middle of the line sale 1,500 - 2000. High was $3,500. Yes full set of EPD's and lineage. And one sire that was a land mark for an actual REA trait passed through offspring. Another Angus breeder who had inferior cattle sold like hot cakes, He had lots of cattle and sires
that we high dollar raised in good conditions to have good EPD's. Both breeders had similar EPD's.
