To investigate the influence of parental fat intake on preferential fat intake by pups after weaning, two groups of dams in study 1 were fed either a low-fat diet (LFD) or a lard high-fat diet (HFD) and those in study 2 were fed either a LFD or a fish-oil HFD after day 5 of pregnancy and during lactation. In study 1, when pups were placed on a self-selection regimen of the LFD and the lard HFD within the first week after weaning, the ratio of the lard HFD intake [lard HFD intake (g)/total intake (g)] by pups of both groups was about 70%. 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 decreased to 20% in week 3 after weaning. In study 2, when pups were placed on a self-selection regimen of the LFD and the fish-oil HFD after weaning, the ratio of the fish-oil HFD intake in both groups of pups nursed by dams fed the LFD and the fish-oil HFD was about 20% for 3 wk after weaning. In studies 1 and 2, although no significant difference in dietary 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 lard HFD was higher than that of dams fed the LFD. These findings indicate that (1) 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 fish oil HFD diet guards against pups' intake of excessive fat.
