2010 display bulls

[LostFarmer]

Guess I missed that memo.  On commercial cattle we usually run a yearling bull and an older bull on 35 to 45 cows.  Not sure how many the yearling gets covered but he keeps the old bull honest.  This year I have a long yearling in with 18 to clean up after the AI.  Yea the yearling looks a little rough come fall but he has 7 months to get ready to go again.

one yearling to clean up 21 replacemnts one yearling to clean up 32 and  1 1/2 yearlings to clean up just under 60.. 1/2 cuz the bull seems to have over done it or injured himself..... a bull should be able to do his job on a day to day basis then take his fence detructing relapse to the lazy life for 9  months

Lostfarmer, I’m not sure what it is I said that you think you disagree with.  A long yearling covering 18 cows is what the old “one cow per month of age” thing suggests.  Running a yearling with a mature bull on 35-45 cows ends up doing the same once you account for the older bull taking the bulk of the load.

However, the “rule-of-thumb” for the proper bull to female ratio is one cow per month of age of the bull up to 3 years of age.

If you run one mature bull to each 30 cows, then 15 cows should be plenty for each yearling bull

In single-sire situations, young bulls can normally be expected to breed a number of females approximately equal to their age in months.  Using this rule of thumb, a newly purchased bull that is 18 months of age could be placed with 18 cows or heifers.

As a rough guideline, however, the working range is approximately 10 to 25 females per yearling bull during a 45 to 60 day breeding season.

For the record, I’m not telling you how to run your cows but stop slamming people for following commons sense management with their young bulls.

What a viscious slam? Are you kidding me? ;D

 

[LostFarmer]

That was not meant as a slam.  I have found that too often the fancier the breeding on a critter the lower the fertility.  I see people baby these bulls along, baby the calves along on creep, baby the cows to get them to even wean a calf and then wonder why we are going backwards in many respects.  If a cow comes up open she ships.  If a heifer can't feed a calf, she ships.  If a bull can't get his job done he ships.  Please don't take offense for none was intended.  LF

It was Show Steaks I was talking about.

I just couldn't figure out what you were disagreeing with because the examples you spoke of fall within the old one per month of age thing.  Of course, that idea is for virgin bulls, not bulls coming from stud.
