0.0% = dog-extruded dry food without beta-glucan inclusion; 0.07% = dog-extruded dry food with 0.07% beta-glucan inclusion; 0.14% = dog-extruded dry food with 0.14% beta-glucan inclusion; 0.28% = dog-extruded dry food with 0.28% beta-glucan inclusion. DM = dry matter. SEM = standard error of the mean. BCFA = branched-chain fatty acids.
