beta-Mannanase ameliorates viscosity-associated depression of growth in broiler chickens fed guar germ and hull fractions
TLDR
In this article, the effects of 2 guar meal fractions at three different concentrations, germ (0, 5.0, and 7.5%) and hull ( 0, 2.5, and 5.5%), and the effectiveness of a beta-mannanase at three levels (i.e., 0, 1x, and 4x; 1x = 1.09 x 10(5) units/ kg) on broiler growth and feed conversion were measured as a function of intestinal viscosity.About:

A dose-response study with the feed enzyme beta-mannanase in broilers provided with corn-soybean meal based diets in the absence of antibiotic growth promoters
TL;DR: The experiment demonstrated that dietary inclusion of beta-mannanase at approximately 50 MU/ton is not sufficient for maximum response, and inclusion at 80 MU/ ton improved broiler gains and feed conversion and increasing to 110MU/ton resulted in no significant additional response.

Levels of β-Mannan in Soybean Meal
H Y Hsiao,D M Anderson,Nick Dale +2 more
TL;DR: Beta-mannan has clearly been shown to be deleterious to poultry and animal performance and a survey of its concentration in SBM confirmed that concentrations are higher in nondehulled samples than in dehulling samples.

The Differences in Intestinal Viscosity Produced by Barley and β-Glucanase Alter Digesta Enzyme Activities and Ileal Nutrient Digestibilities More in Broiler Chicks than in Cocks
TL;DR: The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal Viscosity, digestive enzymes activities and ilean nutrient digestible in different ages of poultry.

The effect of pelleting, salt, and pentosanase on the viscosity of intestinal contents and the performance of broilers fed rye.
TL;DR: The viscosity of fore and hind gut contents was significantly reduced with pentosanase supplementation, whereas the effects of salt or pelleting were not as clearly defined, and weight gain and FCE correlated with fore but not hind gut viscosities.
Journal Article
Do viscous polysaccharides slow absorption by inhibiting diffusion or convection
TL;DR: The results suggest that guar probably reduces absorption by resisting the convective effects of intestinal contractions by delaying the time taken for saline solutions of different resistivity to achieve complete mixing.

Non-Starch Polysaccharide-Degrading Enzymes Increase the Performance of Broiler Chickens Fed Wheat of Low Apparent Metabolizable Energy
TL;DR: The effect of a commercial glycanase product on the performance of 4-wk-old broiler chickens fed wheats with low and normal apparent metabolizable energy values was studied and the enzyme product significantly increased the solubilization of non-starch polysaccharides within the gastrointestinal tract of birds fed both types of wheat diets.

Studies of viscosity as the probable factor involved in the improvement of certain barleys for chickens by enzyme supplementation
TL;DR: The viscosities of extracts from chickens that were fed on barley alone were lowered by enzyme preparations that were effective in increasing the performance of chickens.
