Impact of high-fat diet consumption on stressed dams' behavior. (a) Food intake (% of intake on MS-day 2) during the 180 min separations and (b) mean daily food intake (kcal) over the two weeks of the MS procedure (n=13 for SD–MS and n=12 for HFD–MS). Stressed dams fed a HFD increased their food intake during the 180 min of separation over the 2 weeks of MS and consumed significantly more food compared with standard diet (SD)-fed stressed dams. However, daily food intake (homecage) was not different between standard and high fat-fed dams. (c) Time (s) in light compartment in the dark/light box on PP14 (n=13 for SD–MS and n=12 for HFD–MS). HFD dams showed a reduction of their anxiety-like behavior. (d) Dams' behavior (percent of total behaviors measured) during the dark phase at PP2 (n=4 for SD–MS and n=5 for HFD–MS). HFD dams displayed higher global maternal care toward their progeny (arched back posture, licking–grooming and passive nursing together). * at least P<0.05 compared with standard diet; $ at least P<0.05 compared with MS-day 2 in SD–MS; # at least P<0.05 compared with MS day 2 in HFD–MS. HFD, high-fat diet; MS, maternal separation.
