All methods of measurement Cited by: Estimating Percentage Lean in Live Hogs. The ultimate objective of the pork industry is the production of maximum quantity of high quality lean per unit of energy input. An estimate of percentage lean for a live hog can be predicted if fat depth and loin muscle area are collected using ultrasonics.
