A field experiment was conducted to evaluate the yield and chemical composition of triticalegrain in different crop rotation and tillage systems. The first experimental factor was thecropping system – a) crop rotation and b) monoculture and the second factor was the tillagesystem – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yieldwas found to be 15.4% high...

Six dry dog foods and six dry cat foods with different carbohydrate sources were investigated in digestion trials. Food and faecal samples were analysed for CF, TDF and starch. In dogs, also neutral detergent fibre (aNDFom) and acid detergent fibre (ADFom) were analysed. N-free extract (NfE) was calculated for CF, and similarly for all other fibre analyses. Linear regressions were calculated be...

1. The use of a nylon-bag technique for pig feed digestibility determination was studied. Bags, measuring 25 x 40 mm and containing feed samples, were introduced into the pig gastrointestinal tract through a duodenal cannula, and recovered in the faeces between 23 and 69 h later. The disappearance of organic matter and crude protein (nitrogen x 6.25) from the bags was compared with in vivo appa...

Dietary energy source can influence muscle glycogen storage at slaughter. However, few studies have demonstrated whether the diet-induced change of muscle glycogen is achieved by the transformation of muscle fibre type. This study investigated the effects of dietary energy sources on meat quality, post mortem glycolysis and muscle fibre type transformation of finishing pigs. Seventy-two barrows...

OBJECTIVE This study investigated the effects of different dietary energy sources on early postmortem muscle metabolism of finishing pigs. METHODS Seventy-two barrow (Duroc×Landrace×Yorkshire, DLY) pigs (65.0±2.0 kg) were allotted to three iso-energetic and iso-nitrogenous diets: A (44.1% starch, 5.9% crude fat, and 12.6% neutral detergent fibre [NDF]), B (37.6% starch, 9.5% crude fat, and 15...

In other papers ofthis series (Holden, Pirie & Tracey, 1950; Holden, 1950a, b) the effects of a number of polysaccharases on leaf fibre are described. The only polysaccharase recognized in tobacco leaves in significant quantity is amylase (Frankenburg, 1946), and even this is not present in sufficient quantity to effect complete removal of starch on repeated prolonged incubation. It is convenie...

BIEL, W. and E. JACYNO, 2013. Chemical composition and nutritive value of spring hulled barley varieties. Bulg. J. Agric. Sci., 19: 721-727 The objective of this research was to evaluate the chemical composition and nutritive value of four spring hulled barley varieties (Antek, Skarb, Nagradowicki and Granal) grown in one location in Poland. In the study were determined: chemical composition, a...

Banana peel flour (BPF) prepared from green or ripe Cavendish and Dream banana fruits were assessed for their total starch (TS), digestible starch (DS), resistant starch (RS), total dietary fibre (TDF), soluble dietary fibre (SDF) and insoluble dietary fibre (IDF). Principal component analysis (PCA) identified that only 1 component was responsible for 93.74% of the total variance in the starch ...

The aim of this study was to investigate the effects of feeding oats alone before or after feeding chopped alfalfa or, in admixture with the alfalfa on the glycaemic and insulinaemic responses of horses as well as post-prandial breath hydrogen and methane excretion. Horses were fed in a randomized order, chopped alfalfa as a source of dietary fibre and unprocessed oats as a source of starch. Ch...

3. SACN have reviewed the available scientific evidence for components under consideration for inclusion in the Codex definition on dietary fibre for nutrition labelling purposes, using the SACN frame work for assessing evidence (SACN 2002). These components include total fibre, non starch polysaccharides, fibre components from cereal, fibre components from fruit and vegetables, starch, resista...
