For the 58 goats on test, 12th rib fat thickness ranged from 0.02 to 0.11 inches (0.5 to 2.8 mm) and averaged 0.08 inches (2 mm). As expected, the goats are very lean. Body wall thickness (measured 2 in. from the ventral edge of the rib eye muscle) is a better carcass measurement for goats. This was also measured, but we have not received the data.

As you look at at the rib eye data, be sure to relate it to the size of the goat. Goats which have larger rib eyes relative to their body weight are the goats which excel in this trait. At this point, it is not known if rib eye area is the best indicator of carcass muscling or yield in a meat goat.
