The purpose of this study was to investigate the effect of different doses o f dietary fiber of Tremella fuciformis Berk on lipid metabolism and inte stinal physiology in rats fed diets containing 1% cholesterol and 0.2% cholica cid. Forty-two male Wistar rats were randomly divided into six groups in a 2× 3 factorial design and were fed diets containing different doses (0%、5% or 10 %) of dietary fiber of TFB, with and without antibiotics 0.7g/100g of Nebaci tin (bacitracin: neomycin sulfate = 2:1,w/w) for 4 weeks. The parameters analyz ed included liver and serum lipid concentration , serum and caecal content of short chain fatty acids ,fecal neutral steroids and total bile acids content.T he results showed that rats fed the diet with antibiotics had lower levels ofs hort chain fatty acids in serum and caecal content than rats fed diet withouta ntibiotics.
