PENTOSANS IN SOILS.1

Cereal Pentosans: Their Estimation and Significance. IV. Pentosans in Wheat Flour Varieties and Fractions

Cereal Chem. 65(3):182-185 Total and water-soluble pentosans were determined in flours milled from absorption and soluble pentosans were correlated, and the correlation hard red winter, hard red spring, and soft red winter wheat cultivars grown coefficient increased if the results were expressed on a constant protein at various locations and environments; in two sets of commercial airbasis. In ...

The Effects of Wheat Pentosans in Broiler Diets

The inclusion of untreated rye or barley in poultry diets as a major ingredient causes growth depression. This is due to the high level of pentosans in rye (Antoniou and Marqurdt 1981) and the b-glucan content in barley (Gohl et al. 1977). It has been reported that some wheat cultivars grown in the eastern part of Australia show an unexpectedly low apparent metabolisable energy (AME) (~13 MJ/kg...

Effects of Low Level Water-soluble Pentosans, Alkaline-extractable Pentosans, and Xylanase on the Growth and Development of Broiler Chicks

This study investigated the effects of low levels of water-soluble pentosans (WSP), alkaline-extractable pentosans (AEP), and xylanase on the growth and organ development of broiler chicks. Three hundred and fifty 1-d-old female broiler chicks were randomly allocated into seven experimental groups of five pen replicates, with ten chicks per replicate. The control group consumed a corn-soybean m...

Isolation, partial characterization, and antinutritional activity of a factor (pentosans) in rye grain.

The role of isolated pentosans as the possible antinutritional factor in rye grain was investigated by using the chick as the bioassay animal. Pentosans were fractionated into water-soluble and insoluble fractions, and the content of the two major pentoses, xylose and arabinose, were quantitated. Puma rye contained 2.1 soluble and 7.7 % insoluble pentosans. When isolated pentosans supplied whea...
