The effect diet composition on digesta passage over three sections of the gastro-intestinal tract (GIT) was studied in growing pigs. A control diet (C diet) and three diets differing in the contents of non-starch polysaccharides (NSP) and water holding capacity (WHC) were fed. Results showed a mean transit time (MTT) over the whole GIT over all diets of 75 h. NSP significantly (P < 0.05) decreased MTT over the total GIT and through the large intestine. In contrast, NSP tended to increase the MTT of the stomach contents (P < 0.10). The effects of WHC were limited to tendencies for a decrease of the MTT in the large intestine (P < 0.10) and an increase of the MTT in the small intestine (P < 0.10).
