| Abstract: | Fat balance studies and quantitative analysis of fecal trypsin were done on 2 groups of Beagles fed either a meat-base (8.8% fat) or a cereal-base (10.5% fat) diet. In the amount fed, the meat-base diet provided 2.5 to 3 times more fat than the cereal-base diet, yet the mean daily fecal fat output of the 2 groups was not significantly different. Thus the percentage assimilation of fat in cereal-base diet (90.0%) was significantly (P less than 0.01) lower than that in the meat-base diet (96.9%). Dietary composition made no significant difference in fecal trypsin output, although the mean output from dogs fed the meat-base diet 4 times higher than that from dogs fed the cereal-base diet. |
