The ultimate goal of feeding beef cattle is to develop a meat product that satisfies consumer needs. Nutritional management plays a significant role in determining carcass merit of beef cattle. Certain management procedures (eg, metabolic modifiers, early weaning), general animal health (eg, history of respiratory disease), and certain feed ingredients (eg, trace minerals, antioxidants) can have positive and negative effects on the overall quality of beef that is supplied to the consuming public.
