Eighteen crossbred (Local x Landrace) castrated male pigs weighing from 11 to 14 kg were used in a 2 x 3 factorial arrngement to study the effect source of supplemntary protein (fresh water spinach, fresh cassava leaves or a mixture [50:50 DM basis] of the two) and DL-Methionine on growth performance traits with a basal diet of broken rice. The pigs were housed in individual pens and allotted at random to the three experimental diets within three blocks based on live weight. The pigs are fed cassava leave up to 38% of their DM intake with no symptoms of HCN toxicity. Pig growth rates were always lower on the cassava leaf supplement compared with water spinach or the mixture of cassava leaves and water spinach. There were no differences between water spinach as the only protein supplement and the mixture of water spinach and cassava leaves. There was no effect on performance traits of the DL-methionine. In conclusion, there appear to be synergistic positive effects from combining two sources of protein-rich leaves as supplements to a low protein basal diet for growing pigs.
