b. MarketClasses(dividedbycalfweight)
A good market steer has a powerful look with a large volume of muscle. Look for muscle expression and thickness at and through his top, rump and hindquarter. Another important criteria is a correct degree of finish to indicate quality and cutability in the carcass he will yield. He will have a wide chest with depth and spring of rib with a long body and a moderate frame size, this will allow his weight to range between 1,100 to 1,300 pounds.
