摘要

To investigate the effect of dams' dietary fat type during pregnancy and lactation on fat choice of pups, three groups of dams were fed one of three diets: a low fat diet (LFD), a control diet (CTD) or a high fat diet (HFD). After weaning their pups were offered a self-selection regimen of both a fat protein diet (FPD) and a carbohydrate protein diet (CPD) for 3 wk. Although the ratio of FPD intake [FPD intake (g)/total intake (g)] by pups nursed by dams fed LFD during the self-selection period was higher than that by pups nursed by dams fed CTD and HFD, no significant difference in the ratio was observed between pups nursed by dams fed CTD and HFD. It was considered that pups nursed by dams fed CTD and HFD self-selected FPD and CPD in an adequate fat energy ratio (F ratio) compared to that of AIN-93G and AIN-93M. The ratio of FPD intake by pups of these three groups was 16-21% within the first week after weaning. Although pups nursed by dams fed CTD continued to consume the same ratio of FPD during the self-selection period, the ratio of pups nursed by dams fed LFD increased and that of pups nursed by dams fed HFD decreased. These findings indicate that: [1] pups nursed by dams fed CTD and HFD have the ability to consume FPD and CPD in an adequate F ratio, and [2] preferential fat intake of pups nursed by dams fed LFD is stronger than that of pups nursed by dams fed CTD and HFD.
