✦ Synopsis
The eþ ects of the addition of 100 g kg-1 of psyllium husk (PSY), cellulose (CEL) or natural carob übre (NCF) to a semi-synthetic diet on fat (FD) and nitrogen (NF) digestibility coefficients, metabolic nitrogen utilisation (MNU), net nitrogen utilisation (NNU) and total serum cholesterol and triglyceride levels, were studied in male 'Wistar' rats. No signiücant diþ erences were observed between the three übres with respect to the weight increase of the animals or MNU. Signiücant diþ erences were recorded for the FD of the NCF group (0.91 » 0.01) compared to the CEL group (0.95 » 0.01), as well as on ND (0.88 » 0.00 NCF group, 0.88 » 0.00 PSY group and 0.95 » 0.00 CEL group) and NNU. None of these indexes showed diþ erences between the groups PSY and NCF. For the serum cholesterol levels, there were no signiücant diþ erences between the non-hypercholesterolaemic groups fed PSY, CEL or NCF ; in those in which hypercholesterolaemia was induced (cholesterol and bile bovine 8.3 g kg-1), signiücantly lower values were found in the NCF group (166 » 17 mg dl-1) than in the PSY group (343 » 61 mg dl-1) and in the CEL group (386 » 48 mg dl-1).
