My fault for not pulling the bulls earlier, despite numerous attempts. I saw both bulls showing an interest last August and finally got them moved that day, hoping the damage was not already done. Weaned the calves 7 weeks later & all heifers got a shot of Lutalyse. Never saw any signs of abortion. She was a little older than the other retained heifers so I took her to the vet mid November to get pelvic measured/BANGS; he preg checked her and said he did not feel any signs of pregnancy. All good, right? A few weeks ago I thought it looked like she was getting a gut but dismissed it as me being paranoid. Worked all the cattle yesterday and I'll be darned if she doesn't have a tiny little bag - but big enough to already get a squirt of milk out of a teat. Two of my crew, both of whom have raised cattle their entire lives, estimated she'll calve in about 3 weeks. Went back to check my records, plugged the date I pulled the bulls into the gestation calculator and she's due 5/26. Yup, they nailed it. She'll be 17.5 months when she calves. Both bulls are heifer bulls but one throws calves that average 70-75 lbs & the other's calves are closer to 65-70. Here's hoping the younger, higher calving ease bull is the sire!
So the moral of this story: Lutalyse does not always work and veterinarians are human and can make mistakes.
