We tried Friction on 20 cows one year and got one calf - a heifer. She turned into the best looking heifer of the replacements we kept that year (out of 61 head). She bred via at 14 months old and calved back in September to Rocky Balboa. We did have to assist her during birth (pretty good size calf), but she came through fine and has one heck of a steer calf. She has a perfect udder and milks great. Baby is definitely good enough to show. I've got no complaints on a sample of one.
