last summer we were putting in some embryos and one fell on the ground for 5-10 minutes. we put it in anyway and she calved today. so there is always hope
i once visited with a vet that had an embryo ride around in a petri dish on the floorboards of his pickup all afternoon. when he got home to put some embryos in some recips that were "set up," he discovered it and put it in 'anyway.' same situation, she calved to the implant date. <rock>
