Effects of guar meal by-product with and without beta-mannanase Hemicell on broiler performance
TLDR
Hemicell significantly improved feed:gain ratio of diets containing 5% of each fraction of guar meal versus the untreated diets, and addition of beta-mannanase (HemICEll) increases the upper feeding level for the germ fraction to 5%.About:

Effect of β-Mannanase (Hemicell) on Growth Performance and Immunity of Broilers

TL;DR: Hemicell may improve growth performance and immunity of broilers and significantly increased the serum IgM concentration in 3- and 6-wk-old broilers.

Antinutritional factors and functionality of protein-rich fractions of industrial guar meal as affected by heat processing
N. Nidhina,S. P. Muthukumar +1 more
TL;DR: FTIR spectral analysis revealed the presence several aromatic groups in IGK and slight modifications in the molecular structure during heat treatments, which significantly increased the water absorbing capacity of IGK, but reduced the nitrogen solubility, emulsifying and foaming capacity.
Journal ArticleDOI
Changes in immune and metabolic gut response in broilers fed β-mannanase in β-mannan-containing diets.
TL;DR: Biological pathway analysis showed that the inclusion of additional &bgr;‐galactomannan into the diet resulted in increased signaling related to immune response, relative to the normal control diet (with reduced soybean meal), and Cluster analysis of the kinome data showed that birds clustered first by age, then predominantly by whether &b gr;‐mannanase had been included in the diet.

TL;DR: The extracellular β-mannanase (ManA) produced was hydrophilic, as it was not precipitated even with ammonium sulfate at 80% saturation, and was strongly inhibited by Hg2+ (1 mM), but was sensitive to other divalent ions to a lesser degree.

TL;DR: Results indicate the enzyme is attractive for industrial applications as Mannanase was highly specific towards glucomannan and galactomannan, whereas exhibited low activity towards mushroom powder.

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.

beta-Mannanase ameliorates viscosity-associated depression of growth in broiler chickens fed guar germ and hull fractions
TL;DR: 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.

Guar meal germ and hull fractions differently affect growth performance and intestinal viscosity of broiler chickens.
TL;DR: The results suggest that residual gum was responsible for some deleterious effects seen when guar meal was fed, and that the germ fraction was a superior ingredient when compared with the hull fraction.

TL;DR: Addition of either of two enzyme preparations, MKC hemicellulase or betaganase M, improved growth; birds receiving 100 or 150 g guar meal/kg gaining 96 and 89%, respectively, of the weight gained by control birds from 28 to 56 d of age.
