I just got off the phone with Sinclairs and they said that they havent heard of any calves over 75 lbs mostly in the 70's, They will be breeding a majoirty of their heifers to him
We have had 3 and all 3 have been 85+ lbs. Two out of cows one out of a heifer. The heifer had to be pulled. We like the calves, but will not use on heifers again.
