Effect of white rot basidiomycetes on chemical composition and in vitro digestibility of oat straw and alfalfa stems

Article Abstract:

The chemical composition and in vitro digestibility of the fungus-infected alfalfa stems and oat straws were both species- and crop-specific. Among five white-rot basidiomycete species, Phanerochaete chrysposporium was the most effective in increasing oat straw digestibility and removing lignin. Lignin was removed from oat straw by two species of fungi whereas no lignin loss was seen in alfalfa stems. Cell wall polysaccharides were degraded from both substrates by all species. However, the lost of large bulk of dry matter of both substrates, precludes the practical use of the fungi studied.

Effects of a new molasses byproduct, concentrated separator byproduct, on nutrient digestibility and ruminal fermentation in cattle

Article Abstract:

A concentrated separator byproduct (CSB) extracted from molasses has reduced readily fermentable carbohydrates, elevated crude protein and increased mineral content. Comparison of two chopped forage mixtures with either CSB or molasses fed to cattle showed minimal effects on digestibility parameters, ruminal measurements and blood electrolytes. However, 50% cereal grain-50% forage diet mixtures with either CSB or molasses resulted in a 2.6% increase in dry matter digestibility, which was attributed to improved neutral detergent fiber digestion.

Effect of alkaline hydrogen peroxide treatment on cell wall composition and digestion kinetics of sugarcane residues and wheat straw

Article Abstract:

A study was conducted to identify the changes in digestibility and cell wall composition of wheat straw, sugarcane bagasse and pith from bagasse after treatment with alkaline hydrogen peroxide (AHP). In vitro digestion kinetics were determined and fiber components identified after treating the plant matter with AHP. Results indicated that treatment with AHP improves digestibility of crop residue, probably by removing core and non core lignin fractions.
