Is this a fertile heat or not. Cow calved May 3. We have synced other cows, and this cow has been active with a couple of them when they come in. Tonight she is standing 19 days after calving and has clear discharge. We plan to put an embryo in her. Is it too soon and throwing away an embryo, or could this be real? This would move her up 60 days from her calving date this year.
