β-xylosidase and β-mannosidase in combination improved growth performance and altered microbial profiles in weanling pigs fed a corn-soybean meal-based diet.

ABSTRACT:

Objective

In this study, two glycosidases (XMosidases), β-xylosidase and -mannosidase, were investigated on their in vitro hydrolysis activities of feed and on the improvement of growth performance in vivo in weanling pigs.

Methods

Enzyme activities of XMosidases in vitro were evaluated in test tubes and simulation of gastric and small intestinal digestion, respectively, in the presence of NSPase. In vivo study was performed in 108 weaned piglets in a 28-d treatment. Pigs were allotted to one of three dietary treatments with six replicate pens in each treatment. The three treatment groups were as follows: i) Control (basal diet). ii) CE (basal diets + CE); iii) CE-Xmosidases (basal diets +CE + β-xylosidase at 800U/kg and β-mannosidase at 40U/kg). CE was complex enzymes (amy
