From: Plasma metabolomics reveals lower carnitine concentrations in overweight Labrador Retriever dogs
Discriminant metabolites significant over time in the meal-challenge test, analysed with respect to body condition groups. Dogs were divided into two body condition groups: lean (BCS 4–5, n = 12) and overweight (BCS 6–8, n = 16), and the mixed model repeated measures analysis was applied. Values given as µM concentrations (mean ± SEM). Fasting plasma samples were taken 15 min before serving of a test meal at time 0 (arrow) and metabolite concentrations in lean and overweight dogs are shown as response curves from fasting to 4 h after feeding. No time-dependent variations in overall metabolite response with regards to body condition groups were found (a–j)
