New Mexico | hiefers born Aug / Sept, wean em Dec, rough em over the winter and breed em the next summer at 9 to 12 months of age.
Calf em the next spring.
That moderates your cow size, saves a bunch of feed/grow time, AND keeps your herd at a very high fertility level.
The afore weigh 10 to 11 when they calf which is bout right for most practical purposes.
Alot of cattle drop good eggs weighing in the 550 to 700 lb range so wasting feed and grow time making em weigh 900 to 1000 to breed em and calfing weighing 12 to 1400 is simply a waste in some areas.
As mentioned several times previous it all depends on the area, the operating enviro and other things too.
The reason TX, FL, OK etc have so many cattle is simply because the weather generally produces almost year around natural feed, year around grow time and year long calfing seasons too.
Conversely those hiefers developed on nothing but rocks and scenery thus calfed as long 2's/short 3's make a long lifed cow also ( perhaps not an option for most Midwesterners ).
Those that think it should only be done only one way, thus "thier way" keep working daily in usa corp boardrooms to make it that way for the cattle bus too.
So far they have not been successfull simply because God and Mother Nature are always two to 10 steps ahead of em regarding cattle production.
