In all honesty... I don't have any good info to justify or prove my theory. :)
We run Brangus, Angus, Beefmaster, and one Tiger Stripe bull. Have some experience with Brahman and 50/50 Brahman bulls.
In my limited experience, it would take more than 3/8 Brahman influence from a Brangus, Beefmaster, Braford, ect bull to put that much ear on that calf... from that cow.
I would go out on a limb and say it would take more than a 50/50 bull to put that much ear on that calf... from that cow.
You are right though, time will help a little. 6mo from now that calf may look a lot different. It may grow in to those legs and ears and not show so much Brahman influence.
6mo from now if you put it in the pens and it gets high headed and starts bouncing off the walls. You will know it has strong Brahman influence. :tiphat: That's a joke. On a serious note, spend a lot of time around that calf and move it and its momma around through your pens as often as possible. Acclimate them to process at a young age.
