Has anyone had any good luck with implanting embryos in recip cows? How successful is it?

I my experience about 2/3 of the eggs we've put in have resulted in a pregnancy.

The national average is 60%. You implant the embryo 7 days after standing heat unlike AI when that is 12 or so hours after heat.  A embryo tech should do this as its a little more compicated then AI. The embryo must go farther into the horn on the side the cow ovulated on. Now buying embryos that will work all the time giving you a great calf, that is still hit and miss, but if you have a cow that dosnt have much of a chance of having one. Buying embryos is a good way of improving your cows faster than you can by AI alone. Just pick a mating for steers or heifers, what ever you are looking for.  Most cant do both.

60 to 67%.  ET can probably change your herd a lot quicker and possibly cheaper than  just buying cows and a.i.'ing.  Good luck.

Thank you all very much for your input! It was all very helpful. I was planning on buying some embryos and implanting them in recip cows, I just wanted to check around and see how successful it is first before I bought embryos.

It is best if you know the background on the embryos you are buying... probably surest bet is buying a mating that already is a known winner

I think next best is buying a mating that is unknown... at least someone thought it would work... this should be much less expensive

worst in my opinion is buying embryos that are "sitting in the tank" and have been there a while   ... probably some already got put in and weren't so great... therefor the rest are still "in the tank"... it really takes some fortitude to destroy embryos whose flushmates didn't hit the mark  although I think is the smart thing to do

Just my opinion

By the way I have a few of the second type if anyone is interested (unknown)

I respectfully disagree with your opinion that embryos "sitting in the tank" were from matings that weren't so great.  I would say that 95% of the embryos in our tank worked well.  I can only remember 1 or 2 matings ever that I wasn't please with most of the calves.  In those instances, i liked the bulls, but not the heifers. 

In a constantly changing industry, we are flushing to new bulls annually.  In an effort to get in the newest (and what we think are the best) matings, many of the good, old matings remain in the tank. Not because they are matings that didn't work, just because the new matings take priority.

I assume that many breeders are in this exact same situation.

I agree! I picked up some embryos at a dispersal sale in Nebraska. Got one in last spring, and boy is it a NICE calf. The sire is triple c Invasion and the dam is an old Blackfoot G cow, so 15 years old? He is by far our best bull calf in the spring crop so far! I hope to get more in in the fall!!
