Chickens, turkeys, ducks, geese, guineas, and pigeons are all eligible for grading and certification services provided by the AMS Poultry Programs' Grading Branch. These services are provided in accordance with Federal poultry grading regulations
The difference between standards of quality and the grades assigned to
poultry is sometimes misunderstood. The standards of quality cover the
various factors that determine the grade. These factors, such as fat
covering, fleshing, exposed flesh, discolorations, etc., when evaluated
collectively, determine the grade of the bird.
The U.S. Procurement Grades are designed primarily for institutional use. These grades are: U.S. Procurement Grade 1 and U.S. Procurement Grade 2. The Procurement Grades place more emphasis on meat yield than on appearance.
