Polyethylene glycol (PEG 4000), Browse Plus (BP), wood ash (WA) and boiling water were evaluated as tannin deactivation methods on tannins in Acacia nilotica fruits. Twenty four Matebele goats of mean body mass, 38.7 ± 3.12 kg, were used in a digestibility and nitrogen balance trial. A completely randomized design was used, and the initial weight was used as a covariate in data analysis. The go...

this study was conducted to investigate the influences of raw or acetic acid-treated oak acornon the performance and cecal flora of broiler chickens. a total of 340 one-day-old male and female cobb 500 broiler chicks were used in a completely randomized design consisting of five treatments with four replicates and 17 chicks each. first group was fed with a corn-based diet (without oak acorn) as...

Tannins are naturally occurring protein-binding polyphenols that occur in many forage plants and which reduce nutritive value through inhibitory effects on ruminal and intestinal functions. Some animals have adapted to tannins through the synthesis of tannin-binding salivary proteins, the presence of tannin-resistant or tannin-degrading ruminal/intestinal microorganisms, or other potential adap...

The structures of condensed tannins isolated from two mangrove species, Kandelia candel and Rhizophora mangle, were characterized by 13C nuclear magnetic resonance (NMR) spectroscopy and matrix assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analyses. Results demonstrate that large heterogeneity occurs in degree of polymerization, pattern of hydroxylation, a...

OBJECTIVES To describe the neurolathyrism epidemic in Ethiopia and to identify associated household factors. METHODS We interviewed 589 randomly selected heads of household in Debre Sina district of Ethiopia, the area afflicted by the recent neurolathyrism epidemic. Disease information was obtained for 2987 family members. RESULTS Neurolathyrism patients were detected in 56 (9.5%) household...

The study was conducted on 50 landrace populations of grass pea at Adet Research Center, Ethiopia, using Randomised Complete Block Design in three replications to determine morphological variability and character associations. Evaluations were made on plant and yield characters from eight plants tagged randomly from each plot. The data were subjected to Analysis of Variance (ANOVA), heritabilit...

Saliva appears as a defence mechanism, against potential negative effects of tannins, in some species of animals which have to deal with these plant secondary metabolites in their regular diets. This study was carried out to investigate changes in parotid saliva protein profiles of sheep (Ovis aries) and goats (Capra hircus), induced by condensed tannin ingestion. Five Merino sheep and five Ser...

In the course of screening of plant extracts for anti-influenza viral activity, 50% aqueous methanolic extract exhibited antiviral activity against influenza virus A. Bio-assay guided fractionation of the extract led to the indication of the presence of condensed tannins as the active constituents. This was confirmed by chemical tests as well as by thin layer chromatographic comparison with kno...
