Re:
I like them to be 14-15 months depending on weight before I breed them.
To each his own. I prefer to breed them at 10 - 12 months.
I think there are several factors that cause this difference of opinion on when to breed 1st time heifers.
1. Location, which effects body condition ( 1st heat cycle, BCS including size &weight )
In my area it is not uncommon to have an 8 mo old heifer weighing 900 lbs with a BCS of 8 or better almost year round.
2. Bull used. ( no cross breeding ) I always use a yearling bull ( under 1,000 lbs )on heifers.
My position has always been to let nature take it’s natural course.
Although if I had the proper facilities I would wait for at least her 2nd cycle to breed ,regardless of age
