FFA Poultry Judging Practice Test

The thigh with a back portion that exhibits a disjointed femur from the hip joint would typically be classified as USDA Grade B. The USDA grading system evaluates poultry based on various criteria including conformation, fleshing, and the presence of defects.

In this case, while the disjointed femur indicates a defect, it does not necessarily warrant a lower grade. Grade B birds can have some minor defects, including slight disjointments or other imperfections, but overall, they must still show reasonable quality and meat yield. USDA Grade B allows for these types of issues as long as they do not significantly affect the overall meat quality.

In contrast, higher grades, such as USDA Grade A, require a product to have no defects, while a product that is non-gradable would have major defects reducing its value too severely. USDA Grade C would apply to poultry with more pronounced issues than those found in Grade B but less than those requiring it to be wholly non-gradable. Therefore, based on the information provided, the correct classification of the thigh with a disjointed femur is indeed USDA Grade B.
