with your birthweights Id hate to see what's above your average.. :shock:

Not something enormous, calving unassisted most of the time. Those were ~104-115lbs. Our monster calves were born at 293-294days.

The official gestation for Simmental is 285 days.
I just had a heifer that had been pacing from 5pm to 8pm. She finally laid down at 8:15. At 8:45 calf was born. 4 days early.
I don't go by size, or BCS. But, I do keep records on each cow. Some tend to like to incubate their calves longer than others.
