[QUOTE="simme, post: 1725156, member: 40418"] Embryos are recovered (from the donor cow) 7 days after the AI breeding of the donor cow. They float around in there for several days while they grow prior to attaching to the uterus. The heat cycles of the donor cow and the recipients are synchronized so that they are all in the same stage so that the reproductive tracts of the recips are ready to receive the embryos. Embryos recovered 7 days after breeding and transferred into the recip 7 days after being in heat. Semen and egg are "put together" (fertilized) in the donor cow after AI breeding in the first part of that 7 days. (IVF is different. IVF method puts them together in a "test tube".) Here is an explanation of the process. [URL unfurl="true"]http://extension.msstate.edu/publications/publications/embryo-transfer-the-beef-herd[/URL] [/QUOTE]
