text: Carcass weight predicts what an animal's total retail product will be compared to other animals of that breed. It does not however predict percent retail value, or the actual amount of sellable meat that can be produced from the carcass.
  Fat thickness determined the expected external and seam fat the animal will contain. These two factors contribute to the greatest waste in an animal and best way to reduce economic loss. Fat thickness EPDs can help producers reduce this loss, by using animals with mid range EPDs, so as not to have too little or too much fat.
  Marbling EPDs are also important in the beef industry for predicting palatability in a beef carcass. They show the estimated USDA Quality grading System and marbling score an animal would receive if it were slaughtered. This EDP is different in that it is measured in units of marbling score, and not in weight gained by an animal. Higher values indicate the presence of genes that will produce more intramuscular fat.
