I guess the general apperance of the udder gives some clue as to the milking ability of a cow, but it certainly doesn't tell the whole story. How fast does she fill it up? What is the composition of the milk? How much milk does she actaully produce? I generally look for cows that will have better than average milking ability...get the calf to grow well but not necessarily to simulate the growth that would be expected if the calf were on the donor.
I think the main criteria for selecting recips are: is she fertile?, is she structurely sound? is she disease-free? is she big enough to easily have a calf of the expected size? how is her temperment? does she have strong materal behavior? is she a good milker (hopefully above average)?

I wouldnt purchase some heavy milking recips because of the difficulty in breeding them back at times and also their requirements for maintenance is much higher. Recips should be just avg cows that have a good track record raising calves.
Milk EPD's for example in Simms--- you should try to keep their MM EPD below a 5.. heavy milkers --which simms are just require more inputs and I have 100's of moderate milkers who on avg wean a 650lb + calf on a yearly basis

Not sure where you're coming from on trying to "match" the milking ability of donor & recip. Who cares? If the cow being flushed is worthy of being a donor, than she SHOULD be a good milker, along with being superior to other females in her breed (not just your best cow????)
The goal is to have a "great" calf out of the supposedly "great" cow. The recip can be blind in one eye & crooked legged as long as she breeds, stays healthy, milks well & has a good temp.
The better the recip milks, the bigger her calf should be at weaning.

Does the EPD deal just apply to the calves prelimnary EPDs.

If you're using non-Angus as a recip for an Angus embryo, the calf won't have EPDs. But if you use registered Angus cows, with EPDs, as recips, the calves will have EPDs. You don't have to try and match the recip's EPDs with the donor dam's EPDs; the Assn is able to incorporate all that data into EPDs for the calf.

HELLO!!!! WOW!!! Where to begin, the donor does not raise the calf, the recip does, so if the recip has crappy milk, how is she going to raise a good calf? Just because the donor has good milk does not mean the calf will be fine if raised by a recip with crappy milk. In the same type senario, what if the recip has way too much milk and raises an oversized calf, which would not happen if the calf was raised by the donor with normal milking ability? What good would it do me to raise a calf that was too big or too scrawny? :tiphat:

Frankie":zv6uw21g said:I'd guess embryo calves have Interim EPDs. I don't know if they can get "real" EPDs until they're raised a calf or not. We've reported all the data on our spring 2008 heifers and they all now have "real" EPDs, not Interims.

Okay, well that sorta clears that up, I guess they have a way to calculate the differences in the calf being raised by a recip.

Trust me, I KNOW that. Re-read what I posted. The recip has to be a good milker! If not, she could possibly "stunt" the growth of the calf.
Now, your concern about the recip having TOO MUCH MILK, does not make any sense at all to me. Unless she has so much milk that she is going to get mastitis or scour her calf, the more the better. Are you afraid a recip might do a BETTER job of raising an embryo calf than what the actual donor will do????
The idea is to get the best growth out of what should be a superior calf. What do you mean "too big"??? ---- too big at birth??? too big at weaning???? big, how??? fat?? tall??? You are supposedly producing a calf with superior genetics. The recip needs enough milk to meet those genetics. I'm not recommending a HOLSTEIN.
I must be missing something here. Please explain.
And the EPD situation is an ANGUS thing. Not an issue in other breeds that I know of. At least not my breed.
