Abstract

This work was targeted to evaluate the effects of including 0 or 8% of neutral detergent fiber from grass hay on the morphology of digestive and non-digestive organs of swine receiving starting or growing-finishing diets. It was employed cross-bred animals fed isoproteic and isoenergetic ad libitum rations in a completely randomized experimental design. At the end of each period, animals were slaughtered and eviscerated. It was detected that the fibrous ration increased the weight of empty stomach, large intestine and filled cecum (as a percentage of live weight) of starting animals. In the growing-finishing animals fibrous ration increased the weights of filled gastrointestinal tract and empty stomach. Higher weights of some digestive organs suggest a possible morphological adaptation to high fiber diets.
