Great looking calf KY. You got something there, with your homegrown bulls and the Herf/Ang/Simm blend you are developing. Two hard and fast rules I believe in, and offer as advice to people 1) Don't raise replacements, heifers or bulls. sell the calves and buy a cow. Or bull. and 2) There should only be grade geldings and steers. Breed to the best registered stallion or bull you can afford. Well, here you come with your program that just shoots my ideas in the head!
You have put a lot of thought, and effort in developing your program, and it shows.
