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...

متن کاملNitration of naphthalene and remarks on the mechanism of electrophilic aromatic nitration.
Naphthalene was nitrated with a variety of nitrating agents. Comparison of data with Perrin's electrochemical nitration [Perrin, C. L. (1977) J. Am. Chem. Soc. 99, 5516-5518] shows that nitration of naphthalene gives an alpha-nitronaphthalene to beta-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. Perrin's data, therefore, are considered to be inconclusive evidence...
متن کاملThe 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...
