Background: Cows, heifers, calves and bull run together all year long. Heifer calf is 4 months. No signs of interest from bull YET, but I know it'll happen eventually. I understand a dose of Lutalyse will end an unwanted pregnancy. My question is this, if given a shot every 3 months until I want her bred, and that could be 6 shots, will that eventually affect her ability to breed when I want her to?
