Summary, Etc.A study was conducted to determine the effects of ß-galactomannanase supplementation of diets with high levels of copra meal on nutrient digestibility and performance of growing-finishing pigs. One hundred twenty pigs (Landrace X Large White X Duroc crossbreds) of similar age and weight were used in the study. Pigs were distributed to four treatment groups following a 2 x 2 factorial arrangement in CRD. Two factors involved were level of copra meal (20/25% in grower and 30/35% in finisher) and ß-galactomannanase supplementation (with or without). Results of digestibility trial of grower stage showed no significant differences in CODDM , CODCF, CODEE, CODGE, and DE among treatments. Increased copra meal level in the diet resulted into significantly decreased CODCP (P<0.05). On the other hand, ß-galactomannanase supplementation significantly increased CODCP (P<0.05). highest CODCP was observed in treatment with 20% copra meal plus ß-galactomannanase. At finisher stage, significant interaction effect (P<0.01) of copra meal level and ß-galactomannanase supplementation was observed for CODEE. The CODEE of finisher diet with 35% copra meal without ß-galactomannanase supplementation was significantly lower compared to other treatments. Body weight gain, ADG, and feed efficiency at grower stage were significantly improved (P<0.05) by ß-galactomannanase supplementation. All growth parameters at finisher stage, livability at grower and finisher stages, and back fat thickness were not significantly influenced by copra meal level and ß-galactomannanase supplementation. Likewise, ADG, ADFC, and FE from grower to finisher stage were not significantly afffected by copra meal and ß-galactomannanase supplementation. Mucosal thickness, length of villi, and crypt depth were not affected by the level of copra meal and ß-galactomannanase supplementation in the diet. However, ß-galactomannanase supplementation had significant effect on width of villi (P<0.05). Regardless of copra meal level, ß-galactomannanase supplementation resulted into an increased villi width. Highest IOFPC was attained from sales of pigs fed grower and finisher diets with 20 and 30% copra meal, respectively, plus ß-galactomannanase. IOFPC was increased by approximately 41% due to ß-galactomannanase supplementation
