Hard to breed = hard to calve.
This comment does not pretain to any one bull or breed . But think about how many times have you turned out a group of young heifers of any breed. The heifers that settle the 1st and 2nd time are laying down have the calf . The 3rd, 4th and 5th times bred are usually having the backward, upside down or just they might have normal birth but never make a great mama. But guess who's the last to breed again and again.
I personally have selected for fertility and when you do that Alot comes along with it. Honestly are you going to keep the bull calf out of a female that is impossible to breed?
Since when is fertility single trait selection ??
JTM - I think you're on the right track with Star Bucks
Hard to calve=hard to breed
because at the same time it's the heifers that calve the easiest that breed back the quickest as two year olds. At the same time the easy calvers are more apt to be the ones that stay around and have longevity, another important economic trait!
