 This study found that the dog chew had a predicted metabolizable energy, PME, value of 1272 kJ per 100 grams, which closely matched the actual measured value of 1272 kJ per 100 grams. This indicates that the NRC 2006 equations used to calculate PME values for pet foods can also be used to accurately estimate the PME value of dog chews.
