|Title:||Effects of xylanase supplementation on between-bird variation in energy metabolism and the number of 'Clostridium perfringens' in broilers fed a wheat-based diet||Contributor(s):||Choct, M (author) ; Sinlae, M (author); Al Jassim, R (author); Pettersson, D (author)||Publication Date:||2006||DOI:||10.1071/AR05340||Handle Link:||https://hdl.handle.net/1959.11/161||Abstract:||Three experiments were conducted to examine: (a) the apparent metabolisable energy (AME) contents, the level of non-starch polysaccharides (NSP), and the extract viscosity value of 9 wheat samples; (b) the efficacy of a xylanase in reducing between-bird variation for AME; and (c) the effect of a xylanase on the number of 'Clostridium perfringens' in broilers fed a low AME wheat diet. Experiment 1 revealed that the AME value of wheat varied from 11.5 to 13.6 MJ/kg dry matter (DM), which negatively correlated with the total NSP level (r = –0.97). Experiment 2 involved a 48-cage individual bird trial, where xylanase increased (P < 0.05) the AME from 12.51 to 13.09 MJ/kg DM and reduced (P < 0.05) its standard deviation from 1.13 to 0.52. The standard deviation for feed conversion ratio, ileal viscosity, and faecal viscosity was also reduced. In this experiment, there was a strong correlation between AME and excreta viscosity (r = –0.81) and the caecal xylanase activity of birds fed the control diet was positively correlated with AME (r = 0.72). In Expt 3, xylanase reduced the number of 'Clostridium perfringens', the causative agent for necrotic enteritis, to a non-detectable level in the ileum and caeca of broilers fed a low-ME wheat diet.||Publication Type:||Journal Article||Source of Publication:||Australian Journal of Agricultural Research, 57(9), p. 1017-1021||Publisher:||CSIRO||Place of Publication:||Australia||ISSN:||0004-9409||Field of Research (FOR):||070204 Animal Nutrition||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Other Links:||http://nla.gov.au/anbd.bib-an2856653||Statistics to Oct 2018:||Visitors: 208
