You sure they didn't can they didn't conceive last fall and have been bred since?
We saw both heifers two years ago get rode as calves that fall. We gave a shot of lute about 3 to 5 days later. Neither calved in the following spring. Neither also got bred by the bull as yearlings and were declared open by a vet.
This last fall, we saw another heifer calf being rode by the bull and suspected that a 2nd heifer got rode too. Both got lute. Neither are showing to be heavy bred and would have calved within a month if they would have been bred. We put the bull in on April 20th and like I said he haven't seen either get bred or show any signs of coming in.
We're checking about every two hours because we going past the heifer pasture to check on the mature cows to see if they are cycling so we can AI them. We don't AI the heifers. We just put them in with the heifer bull for their first breeding and calving.
We are seeing from you all responses that maybe we're over thinking it and it's just a coincidence that the only heifers that ended up open after a breeding season were the ones that got lute as calves. We were wondering since the lute is a hormone that it fouled those heifers. We'll preg check at the end of Sept.
