I have composite cattle currently (Angus, Red Angus, Simmental, and Gelbvieh). I was curious to know if I started doing a rotational form of breeding if the heterosis would increase? If so do I breed my cows/heifers with purebreed bulls of each breed or can I breed bulls that are cross of three breeds, ie one bull A, RA, S second bull A, RA, G third A, RA, Charolais?

Any advice would be appreciated! Just looking to better my herd.
