Phenotype
The ultrasound rib fat thickness measurement can be made from the same image used to estimate ribeye area. Fat thickness at the 12th-13th rib is measured at a point three fourths of the distance from the medial end of the longissimus dorsi muscle (12-13th rib interface) and perpendicular to the surface of the hanging ribbed carcass. Ultrasound scanning protocol requires the collection of an image made between the 12th-13thribs using a linear-array transducer and standoff guide that conforms to the curvature of the animal’s back
