IDENTIFICATION OF CRITICAL LACTATION STAGE FOR THE BODY COMPOSITION IN MALE OFFSPRING OF HIGH-FAT FED DAMS

Each stage (early, middle and late) of lactation is a critical period during which maternalmalnutritional can negatively effects on the offspring's body development. We investigatedthe maternal high fat diet (HF) different stages bodyweight male offspring at weaning. Female Wistar rats were fed either HF only duringthe first week (HF1-7 group), second (HF7-14 third (HF14-21 group) andthroughout (group HF1-21) or standard all lactation. Biometricparameters dams evaluated. did not have differencein weight, food intake pad compared with control dams. Regarding theoffspring, higher final weight was observed in males from HF7-14 HF14-21and HF21 groups to control. There an increase retroperitoneal andmesenteric HF14-21 groups. Higher perigonadal fatpat HF21. Consumption throughout causeshigh offspring. Interestingly, each isolated phase also causes importantbody accumulation, mainly week.
