Effects of Algae Derived pure β–Glucan on Rate and Extent of Digestion In Vitro

Abstract

The major purpose of this study was to determine how varying doses of algae-derived pure β– glucan affected in vitro gas generation, volatile fatty acid (VFA) concentrations, methane production, and protozoa populations. Different doses of β–glucan [i.e., 0, 50, 100, 150, and 200 mg/kg feed (DM basis)] were applied to corn silage as experimental treatments. After 6 and 24-96 hours of incubation, the dose of 200 mg/kg of DM β–glucan reduced total gas production more than the other doses (P
