摘要:The research was conducted to determine the effects of Butyrylated Arrowroot Starch (BAS) to the digesta profile and Short Chain Fatty Acids (SCFA) molar ratio. The research was conducted by using simple complete randomized design (CRD). The treatment tested was feed type, which consists of 5 levels, namely natural arrowroot starch, BAS with Degree of Substitution (DS) 0.053; 0.120; 0.187 and AIN93 natural feed. The study was conducted by using 30 Sprague Dawley rats, which were divided into 5 groups, each group consisting of 6 tails. Feeding treatments were given from dayseven until day 33. On day-34 analysis was conductedof the digesta profile and the SCFA molar ratio. Based on the analysis results, it is known that BAS feeding increased digesta weight, decreased digesta pH and increased digesta water content when compared with the AIN93 standard feed. Largest amount of digesta, lowest digesta pH, and highest water content of digesta, respectively 7.19 g, 6.53 and 91.23%, wasobtained from rats fed BAS with DS 0.187. The molar ratio of butyric acid in digesta also increased along with the increasing BAS DS.
