It does seem to be true that some cows and bulls throw either more males or females, even though certain bull do seem to throw more of one gender than the other.
I have also heard the old story - breed early for heifers--late for bulls. I have also heard the story that "female semen" can survive more acidic conditions better than "bull semen" which prefers alkaline environment.
Have wondered if certain types of feed might throw the cows body Ph one way or the other......

Tried Conversation on 2 cows for Nov 2016 calves... both heifers; went ahead and tried him on a heifer in 2016, she also had a heifer calf last week. All Conventional semen. Your sexed semen should be REAL heifer heavy??


Any comment on the quality of the calves?


Heifers are fancy, but will be more selective on dam side. With my small sample, he was pretty consistent. Threw dam's size or smaller frame, with a lot more refinement (bone-wise). Seem very balanced, nice hips, nice front ends & nice dispositions on all, easy to deal with. Birthweights were variable: 58#,92# and 76# Would stick to breeding him to the bigger boned, longer bodied, bigger/coarser cows. The one heifer that calved to him was fine (76# BW); his CED is down to +1, which would usually turn me off of breeding him to heifers, but that could be skewed if he has been bred to a lot of the bigger headed, bigger bw show heifers...who knows?? They were also on the lower end of weaning weights for the group. Will try to attach a picture of one that I practiced clipping on a month or so ago.
