β-mannanase supplemented in diets saved 85 kcal of metabolizable energy/kg, supporting performance, improving nutrient digestibility and fecal microbiome in pigs
Abstract:The effects of β-mannanase supplementation in metabolizable energy (ME)-reduced diets containing xylanase-phytase were investigated on performance, fecal score, carcass attributes, blood profile, apparent total tract digestibility (ATTD), digesta passage rate, and fecal microbiome in grower pigs (n = 40, 26.09 ± 0.96 kg) randomly assigned within 4 treatments: a 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),… Show more
