Very False indeed
We get them bred from 45-60 days post calving, we find we get higher conceptio the smaller the calf is because there is less drain on the cows system
Good body condition score will also affect you conceptio, if she is this she may not cycle
Good minerals too, if she is difficient she will not cycle
I you get her bred within 90 days, she will calve at the same time every year
Ex.: We try to calve around Sept 1 , Then we breed all yearlings around Nov 20th so they will calve on Sept 1
This works for most of our cows but many calve a bit later and we try to bump them back a few weeks every year, slowly grouping every one in a shorter calving group, try not too calve anything in June July or August as it is TOO HOT the following 60 Days, So are bulls rest in August, Sept, Oct., Most of November
