Autor: Geoffrey A. Lane, Tom N Barry, Warren C. McNabb, M.H. Tavendale, Nicola M. Schreurs, Nicolas Lopez-Villalobos

Publikováno v: Journal of the Science of Food and Agriculture. 87:887-899

Indole and skatole are formed in the rumen from the fermentation of tryptophan and have been correlated to the presence of undesirable pastoral flavours in meat from grazing ruminants. A series of four in vitro rumen fermentation experiments was carr

Condensed tannin in the form of a grape seed extract (GSE) was dosed to weaned wether lambs fed white clover (WC) or perennial ryegrass (PRG) over a 9-week period to determine whether the ‘pastoral’ flavour and odour of meat could be altered. The

Organic matter digestibility of poplar (Populus ) and willow (Salix ) forage trees and its in vitro prediction

Autor: Eileen L McWilliam, Nicolas Lopez-Villalobos, Tom N Barry

Publikováno v: Journal of the Science of Food and Agriculture. 85:1098-1104

Cuttings from poplar (Populus) and willow (Salix) trees are used increasingly as supplementary feed for livestock in summer-dry and drought-prone regions of New Zealand. The present experiment aimed to measure in vivo organic matter digestibility and

The effect of supplementing red deer (Cervus elaphus) with different forms of ascorbic acid upon the concentration of ascorbic acid in rumen fluid and blood plasma

Autor: Timothy R. Manley, Roger P. Littlejohn, Ranjan Gurusinghe, Tom N Barry, Stevenson-Barry Jm

Publikováno v: Journal of the Science of Food and Agriculture. 82:1816-1822

Two indoor experiments were conducted at the Massey University Deer Research Unit to study whether the blood plasma ascorbic acid (AA) concentration in farmed red deer (Cervus elaphus) could be raised, using a single large intraruminal administration

Polyphenols and agriculture: beneficial effects of proanthocyanidins in forages

Autor: Tom N Barry, Warren C. McNabb, Rob J. Aerts

Publikováno v: Agriculture, Ecosystems & Environment. 75:1-12

Proanthocyanidins (PA), also known as condensed tannins, belong to the oldest of plant secondary metabolites. These compounds are widespread in woody plants, but are also found in certain forages. Proanthocyanidins can exert effects in organisms beca

Condensed tannins fromLotus corniculatus andLotus pedunculatus exert different effects on thein vitro rumen degradation of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) protein

Autor: Tom N Barry, A. L. Molan, Robert J Aerts, J. S. Peters, Warren C. McNabb, André Brand

Publikováno v: Journal of the Science of Food and Agriculture. 79:79-85

Condensed tannins (CT) or proanthocyanidins (PA), which occur in a restricted range of forages, have the ability to interact with proteins and enzymes and can influence the digestion of plant protein in the rumen. We compared the effects of CT extrac

A series of subtropical grasses and temperate grasses, herbs and legumes were analysed for the presence of extractable and bound condensed tannin (CT) using colorimetric analysis by the butanol–HCl method. Condensed tannins are routinely purified u

The effect of cottonseed condensed tannins on the ileal digestibility of amino acids in casein and cottonseed kernel

Autor: Tom N Barry, Paul J. Moughan, Feng Yu

Publikováno v: British Journal of Nutrition. 75:683-698

The effect of adding cottonseed hulls to casein- and cottonseed-kernel-based diets on the apparent and true ileal digestibility of N and amino acids, and the proportion of this effect accounted for by condensed tannin (CT), were determined using the
