Hi everyone, new to the AI thing and I am starting out with a few crossbred heifers. I want to know what the frame score means. I know it is their size but what should I shoot for? I want to run them on good grass and they will be commercial herd. I really like the looks of red angus. But since these will be sale barn calves probally should go black. I am looking to keep the heifer calves to grow the herd. Thanks for any info
