Protein Fibre Surface Modification
Many natural fibres, including wool, cashmere and silk, are protein-based materials; the dry weight of wool is almost entirely derived from proteins (Maclaren & Milligan 1981). As such, they possess an inherent structural and chemical heterogeneity not found in synthetic polymers. Although typically less heterogeneous than biological fibres, the rapidly emerging range of commercially available ...
متن کاملDetermination and comparison of digestion kinetics of two fibre sources
The aim of this study was to determine and compare the digestion kinetics of two fibre sources (lucerne, maize stalk) in different segments of the digestive tract of geese. Sixty Jilin nongan white geese were divided into two groups and fed with a lucerne or maize stalk diet. After 30 days of feeding, all of the geese were fed with Co-EDTA as the marker of liquid digesta, and n-alkane was used ...
متن کاملDigestion of High Fibre Roughage in the Rumen of Sheep
The extent of digestion of high fibre spear grass (Heteropogon contortus) hay by sheep was examined to determine the factors which limit its utilization. The mean organic matter (OM) intake (22 g/kgu.'3/day) and digestibility (39%) were low and all animals were in negative energy and nitrogen balance. Mean retention time in the rumen for the liquid phase marker (Cr-EDTA) was long (17.9 hours) a...
متن کاملDigestion Modelling in the Small Intestine : Impact of Dietary Fibre
In this work, we continue the modelling of the digestion in the small intestine, started in a previous article, by investigating the effects of dietary fibre. We recall that this model aims at taking into account the three main phenomena of the digestion, namely the transit of the bolus, the degradation of feedstuffs and the absorption through the intestinal wall. In order to study the role of ...
متن کاملGenetic influences on carbohydrate digestion.
The diversity of the human genome leads to many functional differences between individuals. The present review focuses on genetic variations, both rare and common, that are of relevance to digestion of the sugars and starches that form a major part of human diets, and considers these in relation to the evolution of our species. For example, intolerances of dietary saccharides are not usually li...
