Phenotype

Ribeye area is an indicator of muscling. The longissimus or ribeye muscle is measured at the 12th rib by using a grid or a ribeye tracing that is measured with a compensating polar planimeter or image analysis system.

Adjusted Value

Ribeye area is adjusted to an age constant.

Genetic Evaluation

Carcass weight is generally included in a multi-trait model with traits such as ribeye area (carcass and ultrasound). Direct effects only are fitted.

Usage

Ribeye area contributes to the yield grade equation, but to a lesser degree than does back fat thickness. It is not an economically relevant trait but is an indicator of muscle and an indicator of the economically relevant traits complex of yield.
