You can use Santa Gertrudis or Beefmaster or Brangus (black or red) cows and then cross with an English type bull (Hereford, Polled Hereford, Red Angus,Shorthorn, Murrey Grey or Black Angus) and produce a calf that will fit any order buyers bill. Calves will be less than 1/4 Brahman-influence and produce a high quality carcass. A Continental bull (Charolais, Simmental, Gelbvieh, etc.) will produce lots of pounds of calf to sale and will feed good. You will be shooting for the select market which there is a demand for.
As other have mentioned, a straightbred calf will receive some discount. Take advantage of hybrid vigor, besides the red motley faced cows make an excellent cow.
