After she got pregnant with her bull, my wife doesn't relate to other bulls, her uterus only receives seed from her bull, he lives with us, and fulfills his role as a sire, my wife's belly started to stretch, now at 16 weeks, she is 50 years old and her bull will continue breeding with my wife until she can no longer get pregnant, we are happy and hope your bull will reproduce 4 or 5 more babies.
