Heifer calves out of younger bull .

[Stocker Steve]

Some bulls seem to throw sexed semen. I have one who has been over 75% bull calves for 3 straight years.

She's facing the wrong direction when she's bred.

I actually got to pondering over this and Contacted Dr. Bill Beal the Repro Specialist at Va Tech. asked him if there was anything I could do to change the outcome...

he suggested sexed semen...

I decided to try it and looked up the select sires sexed semen bulls and ordered five units of

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?

Back on the heifer side of the coin ! Two more today ; heifers 9 - Bulls 5 . 8 to go.

 

[coachg]

Update : 10 heifers and 7 bulls , with 5 November calvers due soon. The 10 and 7 included a set of twins we lost, one of each sex.

theoretically no difference, from antidotes cows bred earlier in standing heat have higher % of females than bred late in standing heat.... no data to back it up.... so not worth much

Soooo, theoretically, by increasing your bull battery on your herd. You'd get more bred at the beginning of their heat cycle, increasing the chances of having heifer calves.

That was the jest of my original post. I have always heard younger bulls are more aggressive breeders and will breed earlier in a cows cycle thus getting more heifers .

Update on heifers : 2 more born today. 11 live heifer calves - 7 bulls . 2 to go. One will be this week and the other probably Dec.

 

[FlyingLSimmentals]

Vegas my new Herd Sire first calves have been 14 Heifers and just 4 Bulls.

 

[coachg]

1 more to calve ; got another heifer ! 12 heifers - 7 bulls as of 11/6 .

Coach

We have had a bull heavy calving year this season, 94% completed and 60% of them are bulls, we lost one over the weekend, it was the last heifer we had left to calve found her to late the calf had a leg turned back, Once they got the leg straightened out she had the calf on her own before they could get the chains on. We hope to have all of them on the ground by Thanksgiving.

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......

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.

I have a 4 yr old bull. He's had 5/6 bull calves this year. Just put him in w 4 900 lb heifers yesterday. He is a happy boy. Was smoking a cigar this morning.
