摘要: This study investigated the effects of incorporating a mixture of fructooligosaccharide (FOS) and resistant maltodextrin (RMD) at a ratio of 1:2 on body fat accumulation and fecal bacterial parameters in rats. Our results indicated that high dietary fat consumption might effectively (p < 0.05) increase body fat, but consequently inducing a significantly (p < 0.05) higher growth of C. perfringens and retarded growth (p < 0.05) of the Bifidobacterium spp. in the large intestine. As compared with the high fat control, an incorporation of the FOS and RMD mixture at a high dose (0.97 and 1.94 g/kg body weight, respectively) could result in a significant (p < 0.05) reduction in feed efficiency (-16%), total visceral fat (-17.4%), non-visceral fat levels (-20.3%), and total body fat (-19.2%). Furthermore, feeding the FOS and RMD mixture at a high dose was capable to counter the above undesirable impacts by reducing the C. perfringens count (-14.8%) and increasing the total Bifidobacterium count (134.4%) and total fecal short chain fatty acids (195.4%). A supplementation of adequate amount of FOS and RMD might confer a concreted solution to the obesity and deteriorated fecal bacteria profiles due to high fat consumption.
