I recently found a group of heifers that have been pastured with their bull siblings. they range from 12 to 18 months. i am sure that some , if not all, may be bred. they are out of pretty good stock and look really good: the price is also right. i considered buying them and treating them with lutelyse, then breeding them all together later. also, considered having them preg checked and only using lutelyse with the ones that were way too young. just wanting some opinions.the sire was simangus. the mommas were angus cross cows.
