Wide variations in amino acid composition and proximate components between pet food-grade and feed-grade poultry by-product meals (PBM) have been reported from this laboratory. Four samples of pet food-grade and feed-grade PBM were evaluated for TMEn and proximate composition. The TMEn values for feed-grade PBM ranged from 2,775 to 3,555 kcal/kg, whereas pet food-grade PBM varied from 3,316 to 3,401 kcal/kg.
