A total of 18 growing pigs (landrace x Yorkshire cross) were fed starter diet from weaning (12 kg) to 20 kg and grower diet from 20-40 kg. The pigs were housed in individual pens and distributed at random to three treatments, following a completely randomized design. The ESPCM is composed of 770 percent sweet potato meal and 30 percent copra meal that partially replaced 20 percent and 30 percent of corn in the ration. ESPCM can replace up to 30 percent of corn in the grower diets without significant depression in feed intake, live weight gain and feed efficiency. Feed efficiency was slightly better in pigs receiving the highest amount of ESPCM. ESPCM was equally palatable to the animals as the yellow corn as shown by their similar feed intake in the different treatments. The dressing percentage was not affected by feeding ESPCM. Even the backfat thickness and loin eye area did not differ among the treatments considered
