Don't know if this has been discussed on here or not. I see a lot of guys are running calving ease bulls on their cows as well as heifers. I think guys are gonna run into a lot of problems with cattle and small pelvis measurements by doing this. I'm not sure why anyone would want to use a minus EPD birth on cows. If your cattle can't push out a 85-90 lb calf without assistance, maybe you already have a problem. This obviously is if you are keeping back your own replacements, which I do.
