I don't know who your tech is, but if he doesn't work with you and give them another try, I'd find a new tech. In his/her defense, some heifers just aren't going to breed, but I wouldn't give up on them until I'd tried them 2 or 3 times. I don't think another blood test is going to make much difference...the chance is slim to none that the results are going to come back any different. Sounds like they are just trying to buy more time that you really don't have. I'd be sweating bullets too if I charged someone that much and didn't stick any of them. :2cents:
