Abstract

Carcass composition (n= 338) and meat quality (n=151)data were collected on pigs from the eighth generation of the Iowa State University Residual Feed Intake (ISU RFI) selection project fed either high or low energy diets. Both RFI line and diet were found to impact carcass composition, while having minimal effects on pork quality and sensory characteristics. RFI shows promise as a selection tool for improved efficiency without compromising pork quality, even if fed low energy diets.
