The objective of the study was to compare the digestibility of nutrients, energy and dietary fiber in conventional feed ingredients fed to Philippine native and modern crossbred pigs. A total of 6 Philippine native (Black Tiaong) and 9 hybrid pigs (PIC L337 x C24) were randomly allotted 1 of 3 experimental treatments arranged in a 3 x 6 (native pigs) and 2 x 9 (hybrid pigs) Latin square design. A corn basal diet consisting of 94.89% corn (as-fed basis) and vitamins and minerals was formulated. The next two diets were formulated by mixing 70% of the basal diet with 30% (as-fed basis) soybean meal and rice bran. The apparent total tract digestibility (ATTD) of nutrients, NDF, ADF and ash and the DE and ME concentration of each ingredient was calculated using the difference procedure. Results showed that ATTD of GE and ME of the diet were greater (P0.001) compared with those measured in native pigs were greater (P0.001) compared with those measured in modern crossbred pigs. Native pigs also had greater (P0.03) ATTD of CP, crude fiber, NDF, ADF, and ash and tended (P
