Table 1 Effects of β-mannanase supplementation in metabolizable energy-reduced diets containing xylanase-phytase on growth performance, fecal score, and ultra-sounded backfat thickness and loin depth of grower pigs (n = 10 per treatment). ^aIBW: initial body weight, FBW: final body weight, ADFI: average daily feed intake, DWG: daily weight gain, G:F: gain to feed ratio. ^bA control diet containing isolated phytase and xylanase valued at 40 kcal of ME/kg (CD0), CD0 + β-mannanase (0.3 g/kg valued at 30 kcal of ME/kg) (CD70), CD0 + β-mannanase (0.3 g/kg valued at 45 kcal of ME/kg) (CD85), and CD0 + β-mannanase (0.3 g/kg valued at 60 kcal of ME/kg) (CD100). ^cSEM: pooled standard error of the mean.

From: β-mannanase supplemented in diets saved 85 to 100 kcal of metabolizable energy/kg, supporting growth performance and improving nutrient digestibility in grower pigs
