Ten flatulent but otherwise healthy subjects were studied while consuming two or three different diets. Flatus collections showed that a bean-containing, high crude-fibre diet produced more flatus (mean 49.4 ml/hr) than either a diet with a restricted crude-fibre content (mean 26.7 ml/hr) or a liquid chemically defined diet (mean 10.9 ml/hr). There was a close correlation between the crude-fibr...

Crude fibre determination is commonly used to estimate the quality of foods of plant origin on the premise that it constitutes their least digestible fraction. Therefore, a criterion for evaluating fibre methods is thc recovery of indigestible plant residues. ‘I’he so-called Weende method for fibre estimation was not developed at Weende, but at Moglin after 1806 by Heinrich Einhof, who assumed ...

A digestion trial in vitro was conducted to study effects of supplementation of NSP (non-starch polysaccharides) degrading enzyme (feed grade) on cell wall degradation and digestibility of nutrients in barley. The slices of barley were soaked in distilled water with or without 0.15% non-starch polysaccharides degrading enzyme. Microscopic examination of the slices showed that the endosperm cell...

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...

Nutrients not absorbed in the small bowel will form substrates for microbial growth in the colon which may have implication for the development of colon cancer. The aim of the present study was to investigate whether fibre-rich oat and barley diets increase the excretion of energy-supplying nutrients from the small bowel compared with a low-fibre wheat diet, and whether a possible increase coul...

Prediction of carbohydrate fractions using equations from the Cornell Net Carbohydrate and Protein System (CNCPS) is a valuable tool to assess the nutritional value of forages. In this paper, these carbohydrate fractions were predicted using data from three sunflower (Helianthus annuus L.) cultivars, fresh or as silage. The CNCPS equations for fractions B2 and C include measurement of ash and p...

1. The fermentative breakdown of dietary fibre from various sources in the intestinal tract was studied using rat balance experiments and gas-liquid chromatograhic analysis of dietary fibre monomers in feed and faces. 2. On a basal diet with 690 g maize starch/kg but no added fibre, small but detectable amounts of polymeric glucose, rhamnose, arabinose, xylose, galactose, mannose and uronic aci...

Black soldier fly larvae (BSFL) are highly efficient at converting organic substrates into insect biomass suitable for livestock nutrition. BSFL conversion efficiency depends on the nature of their feed, and formulation approaches use macronutrient contents to reach a targeted performance. However, digestibility varies between ingredients data is lacking due methods unsuitable insects living in...

This study aimed at assessing the impact of four barley forms on total tract apparent digestibility of dietary fibre in horses fed a large amount of starch in the morning meal (0.27% BW). Processed barley forms had a greater pre-caecal starch digestibility than the whole form. Based on this result, we hypothesised that using barley-processing methods would limit the potential dumping of undegra...

Fumaria vaillantii Loisel. (Family-Fumariaceae), a well-known crude drug is used in Indian system of traditional medicine for diverse pharmacological activities like anthelmintic, antipsoriatic, hypoglycemic, hepatoprotective activity, etc. This study presents pharmacognostic and phytochemical evaluation of whole plant of F. vaillantii to establish identification markers. Microscopy showes pres...
