Comparison of a xylanase and a complex of non starch polysaccharide-degrading enzymes with regard to performance and bacterial metabolism in weaned piglets.

Weaned piglets were fed a wheat based diet either non-supplemented or supplemented with a multi-enzyme preparation or a xylanase mono-enzyme preparation, respectively. Both enzyme preparations increased live weight gain nonsignificantly, but only animals of the xylanase group showed a trend (p = 0.076) for an improved feed conversion.

[Influence of a xylanase feed additive on Lactobacillus species in the jejunum of piglets].

rRNA extracts from the jejunum of rearing piglets fed a wheat/rye based diet with or without a xylanase feed additive were hybridized against eight Lactobacillus spp. specific digoxigenin labelled oligonucleotide probes. Known concentrations of sample- or culture RNA extracts were used to calibrate and quantify hybridization signals from different sample extracts and hybridizations.

Isolation and identification of mixed linked beta -glucan degrading bacteria in the intestine of broiler chickens and partial characterization of respective 1,3-1,4-beta -glucanase activities.

Media with 1,3-1,4-beta -glucans as selective markers were used for isolation of non-starch-polysaccharide (NSP) degrading bacteria from the intestinal tract of broiler chicken. Formerly unknown 1,3-1,4-beta endoglucanase activities in various bacterial species were identified in this study. E.

Response of performance characteristics and fecal consistency to long-lasting dietary supplementation with the probiotic strain Bacillus cereus var. toyoi to sows and piglets.

As part of an interdisciplinary research project, we studied the performance response of sows and their litters to the probiotic strain Bacillus cereus var. toyoi as well as feces consistency of piglets. Gestating sows (n=26) were randomly allotted into two groups.
