Summary of the trial design for the voluntary food intake studies. For both canine studies, dogs were fed each diet, sequentially, for periods of 7 days. The test protocol (Test) was performed on 3 non-consecutive days for each study period, with food intake being limited to 80% of MER (e.g. study 1: 88 Kcal/kg^0.75; study 2: 96 Kcal/kg^0.75). For the feline voluntary food intake study, cats were fed each diet ad libitium, sequentially, for periods of 7 days, with each an initial 2-day adaptation phase (ADA) and then a 5-day test phase (Test)
