Effects of flour or flaxseed oil upon intra-abdominal adiposity in male rats subjected to early weaning

The present study was designed to evaluate intra-abdominal adiposity in rats subjected to early weaning and subsequently treated with diet containing flour or flaxseed oil until young life. Pups were weaned for separation from mothers at 14 days (early weaning, EW), and 21 days (control, C). After 21 days, control (C60) was fed with control diet. EW was divided into control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. At 21-60 day, intra-abdominal fat mass were evaluated. At 60 days, retroperitoneal adipocyte area was determined. At 21 days, EW group displayed lower (P<0.05) intra-abdominal fat mass. At 60 days, EWC60 group displayed lower (P<0.05) intra-abdominal fat mass. Adipocytes area were lower (P<0.05) in experimental groups. EWC60 displayed lower (P < 0.05) adipocytes area (vs. EWFF60 and EWFO60). Flour and flaxseed oil diets contribute to recovery of intra-abdominal adiposity after precocious interruption of lactation.
