[QUOTE="Fire Sweep Ranch, post: 1487919, member: 18809"] Exactly what my embryologist has said all along. IVF embryos vary from donor to donor, some have excellent results and some never stick. The technology has come a long ways, but it still is not at the same level as conventional. With IVF, it is important to get the donor collection sheet to know what stage they were froze at, and on most we put in the IVF frozen embryo one day later (day 8 instead of day 7). If I wanted heifers from a flush, I would use IVF and take the lower conceptions. I would also set up recips to put in embryos fresh, and not frozen. We will have our own little experiment here; a good customer of ours (bought a bull and cows from us) bought some IVF heifer embryos, sired by Milestone (and Stella Y5243). He never uses embryos, and asked if I could take one of his cows and implant for him, and he would give me the other two for my troubles. Worth the chance, he is bringing the cow out in March and I will keep her until she either passes 70 days OR I will AI her for him if she does not stick the embryo. I will get to try the other two on my own cows, all three eggs are 7-2 or 6-2 stage. Sure would love a heifer out of that mating.... one can dream, right? [/QUOTE]
