Caecal microbial activity, digestion and gut health were analysed in the young rabbit, in response to fibre substitution by starch, in diets with high proportions of rapidly fermentable polysaccharides (pectins+hemicelluloses:acid-detergent fibre (ADF) ratio of 1.7). A range of five diets corresponding to a 60 % linear reduction of the ADF level (230 to 92 g ADF/kg) without changes in the fibre...

Starch and fibre contribute to the energy components add functionality end-product feed ingredients. An understanding of impact processing on carbohydrate content will support accurate formulation feed. Six ingredients, grown or sourced in Canada, were used this study. They included five pulses, Amarillo peas, Dun chickpeas, lentils, faba beans, soybean meal (SBM) as a comparison. All ingredien...

The effect of changing dietary energy and crude fibre concentrations on the utilization of metabolizable energy (ME) was investigated in four growing ostrich chicks by addition of lucerne meal to a maize-lucerne based diet. The experiment was carried out in an indirect open circuit calorimeter. When ME concentration was lowered by 7.5%, cell wall digestibility decreased by 9% and energy metabol...

During two years, four samples per year were collected in Vietnam from rice bran, cassava residue, brewer's grain, tofu residue, soybean meal, coconut cake, sweet potato vines and water spinach for chemical analysis and assessment of water holding capacity (WHC). The selected feedstuffs represent fibre-rich plant sources and agro-industry co-products commonly used in pig feeding in Vietnam. The...

One sustainable method of removing oil spills is the use sorbents. In this study, aerogels made from paper waste and crosslinking starch are investigated as Aerogels have a high porosity and, thus, achieve sorption capacity. The compared with aerogel samples that also contain hemp fibres composite. After hydrophobisation methyltrimethoxysilane, maximum capacity crude oil, marine diesel lubricat...

Eight Aspergillus niger strains which produced strong starch degrading amylase were isolated from the soil using a medium containing Remazol Brilliant Blue (RBB) starch as substrate. Amylase production was detected by the disappearance of the blue colour around the colony. Among the isolates, A. niger AM07 produced the largest clear zone (7.0mm) on Remazol Brilliant Blue (RBB) agar plate and al...

Effects of particle size and physical effective fibre (peNDF) of rice straw in diets on chewing activities, feed intake, flow, site and extent of digestion and rumen fermentation in goats were investigated. A 4×4 Latin square design was employed using 4 mature Liuyang black goats fitted with permanent ruminal, duodenal, and terminal ileal fistulae. During each of the 4 periods, goats were offer...

SIR,-Those of us who have worked in Africa when diabetes appeared to be uncommon must congratulate Dr. A. C. B. Wicks and Professor J. J. Jones (31 March, p. 733), who have extended the observations of other doctors' in Salisbury, Rhodesia. They are beginning to elucidate the role of refined carbohydrates as a factor in the pathogenesis of diabetes mellitus. If one wishes to state the degree of...

Wang, M., Jiang, J., Tan, Z.L., Tang, S.X., Sun, Z.H. and Han, X.F. 2009. In situ ruminal crude protein and starch degradation of three classes of feedstuffs in goats. J. Appl. Anim. Res., 36: 23-28. Ruminal crude protein (CP) and starch degradability of three classes of feedstuffs: cereals (maize, wheat, barley, buckwheat, rice, millet and sorghum), legumes (horse bean, soybean, pea and mung b...
