Their Weaning Pups

lttrd high-fat dict (HFD) and those in study 2 were fed either a LFD or a fish-oil HFD after day 5 of prcgnancy and during lactation, In study ], when pups were placed on a selilselection regimen of the LFD and the lard HFD within the first week after vreaning, the ratio of the lard HFD intake [lard HFD intake (g)ftotal intake (g)l by pups of beth groups was about 7096. Although pups nursed by dams fed the lard HFD continued to eat the same ratio of the lard HFD, the ratio for pups nursed by dams fed the LFD gradually dccreased to 20% in week 3 after weaning, In study 2, when pups were placed on a $eliLselection regimen of the IiFD and the fish-oil HFD after weaning, the ratio of the fish-oil HFD intake in both groups of pups nursed by dams fed Lhe LFD and the fi$h-oil HFD was about 20`Z) fbr 3 wk aftcr weaning. In studtes 1 and 2, a]thougb no significant difference tn dictary intake or body weight of dams and pups was observed among all groups through the experimental period, perirenal fat tissue weight of dams fed the Iard HFD was higher than that of darr]s fed the LFD, Thcse findings indicate that C].) fat preference of weaning pups nursed by dams fed the lard HFD is higher than that of weaning pups nursed by dams fed the LFD, and {2) intake of dam's fishoit HFD dtet guards against pups' intake of excessive fat.
