New Mexico | problem with NOT pulling bulls for a while ( those who calf year around ) is ALOT more trich risk.
Trich is basically a vaginal protoza....dies ( starves itself ) out in cows with 60 to 70 days of no sexual activity.
Have had clients try the 42 to 45 day deal, I'm NOT sold on that.
Sure cleans up cows to the fertiles...but that 1st couple years is WOW for cull cow numbers.
Generally been 36 to 39% opens the 1st year of that program, 2nd year 18 to 20%.
3rd year will run 9 to 10%...should run 5% opens by the 4rth year.
Has been working cash wise due to incline of cull cow prices.
You've gotta be pretty adept at sourcing bred youngs to replace the culls to trade at Flush prices / costs though.
Just tend to think practical perhaps...better off to have some late pairs and sell those instead of open cull cows. MO.

How long do you leave your bulls in?
