i had a heifer have a calf 2 weeks ago out of my judd ranch bull, i did not buy him for heifers, 73 lb act BW 1.3 HAHA, she got bred on the cow under 9 months. WOW what a monster calf, i went to check on her and when i seen the hooves sticking out i went and got help. everybody was doing hay, all i could see was hooves and not much more room. it took 5 of us and a set of pullers to pull the calf, he was a little swelled, head and front feet, and the heifer was down for 2 days. but they are doing great now, she is milking well and is a a good mother. thank the Lord for good neighbors who have a dairy with holstiens, and calf pullers, and experience. i have calved alot of heifers but not like that.
