Just except there are good and bad bulls for calving in most breeds, just have to find the good ones same with some cows.We have just calved 12 out of a group of 20, BBX and Limx heifers at 2yrs old to an Angus bull, all heifers pelvic scored, fed tmr as recommended, look in perfect condition for calving but its been hell.
So far 1 calved unassisted, 2 needed a bit of help, 5 were really hard pull and 4 needed C-Section.
The calves not that big but just have big shoulders which has caused the problems. This is the first time using an AA bull, normally use Lim with few issues.
Had to assist one of our pedigree blues a few days ago as the calf had a leg back, shoved it back in pulled the leg round and it fell out easy enough previous 3 to that calved on their own,
Not sure what you blame a leg back on, cows fault? Calves fault? Or just one of those things ?
Last really bad calving we had here was an Angus heifer on to an Angus bull, hard pull ended with a dead calf, we have used other Angus bulls since without much hassle.
