Yes, used on a stouter cow, and I think a cow that is a little straighter in its back leg, my calf out of him has heatwave on the bottom side, but she has a quite a bit more leg set. That being said she is very good, great profile super deep rib and expansive ribbed. Super stout, and SUPER HAIRY! And another thing, that 50 pound birthweight is not just a bluff, my calf came real easy and was up nursing in no time probably 60 poud birthweight. Any other questions feel free, I will definitely be using him again
