Body composition in male rats subjected to early weaning and treated with diet containing flour or flaxseed oil after 21 days until 60 days.
The aim of this study was analyzed if the flour or flaxseed oil treatment contributes to body composition in male rats subjected to early weaning. Pups were weaned for separation from mother at 14 (early weaning, EW) and 21 days (control, C). At 21 days, part of the pups was evaluated (C21 v. EW21). After 21 days, control (C60) was fed with control diet. EW was divided in control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. Body mass, length and body composition by dual-energy X-ray absorptiometry were determined. EW21 (v. C21) and EWC60 (v. C60 and EWFF60) showed lower (P<0.05) mass, length and body composition. EWFO60 (v. C60 and EWFF60) showed lower (P<0.05) body mass and length, body and trunk lean mass, bone mineral density and content and bone area. Flaxseed flour, in comparison with flaxseed oil, contributes to recovery of body composition after early weaning.
