In order to evaluate the effect of taro (Colocasia esculenta (L.) Schott) meal on the productive performance and morphometry of the gastrointestinal tract of fattening pigs, 16 castrated male animals as a result of an alternate crossbreeding of Largewhite x Duroc x Pietrain were used, with an initial liveweight of 69 kg. They were distributed into two equal groups of eight pigs and each pig constituted an experimental unit. Two treatments were evaluated: a control diet T0 (corn and protein concentrate of pigs) and T40 (substitution of corn in 40% for taro tuber meal), according to a completely randomized design, and an analysis of variance was also carried out. Daily food intake (DFI), daily weight gain (DWG), food conversion (FC), final weight (FW), carcass yield (CY) and dorsal fat (DF) were determined. In addition, the GIT, stomach, small intestine, large intestine, caecum and liver of the animals were weighed and measured. There was no effect (P> 0.05) for the DFI, DWG, FC, CY and DF. Likewise, there was no effect (P> 0.05) for the weight of the GIT, stomach, small intestine, large intestine, caecum and liver. There were also no differences (P> 0.05) for the elongation of the GIT, small intestine, large intestine and cecum. Under the conditions of this study, the use of taro tuber meal as a partial substitution of corn in the diet is feasible, since it does not have a negative influence on the indicators of productive performance nor on the morphometry of the gastrointestinal organs of fattening pigs.
