HF, high-fat/low-fiber; LF, low-fat/high-fiber; SEM, standard error of the mean. Gamma-GT, glutamyl transpeptidase; GOT, glutamic oxaloacetic transaminase; GPT, glutamic pyruvic transaminase; AP, alkaline phosphatase; HDL, high-density lipoprotein; LDL, low-density lipoprotein; CRP, C-reactive protein. Sampling Date 1 and 2: After four and six weeks. Sampling Date 3: One day before slaughtering. With regard to the diet, data not sharing the same letter (a, b) within a column and for one parameter assessed are significantly different (p < 0.05); With regard to the experimental weeks, data not sharing the same letter (w, x, y) within a row are significantly different, for HF or LF (p < 0.05). Values represent least squares means.
