Instrumentation is used extensively to facilitate USDA yield and quality grading of carcasses of which species?
Used mainly for beef, pork, and lamb carcasses to help assess lean meat and quality.

Contrast three primary differences between USDA inspection and USDA grading
Inspection is mandatory, focused on safety, and paid by taxpayers. Grading is voluntary, predicts eating quality and value, and is paid by producers.
