Real-time ultrasound is a valuable tool for measurement of loin intramuscular fat (IMF) in the pig and is being utilized by genetics companies. If IMF becomes a component in pork carcass pricing in the United States, producers of commercial market pigs may demand terminal line genetics with the ability to generate higher levels of IMF in their commercial progeny. Thus, swine genetics companies will need to utilize the most time-efficient and accurate methods available for predicting IMF content in live animals to stay competitive.

Results can be used as a decision making guide for equipment and procedures used for the prediction of IMF. Useful information is provided for those interested in enhancing their IMF prediction techniques.
