I have an angus cow that aborted at 7 months. I gave her 72 hours to pass the placenta then hauled her to the vet. He pulled on it a little, gave her an antibiotic shot and told me some research has shown she will be better off if you let her be. It's now 5 days since the abort and it's still in. What would you guys do? Has anyone used a Lutalyse shot in treating this?
