effect of heat processing on the nutritive value of broiler litter, as a potential ruminant feedstuff,was studied in two pilot plans, processing through an assessment of chemical composition, proteinfractionation according to cncps as wells digestibility making use of tilley and terry method. in amanufactory located in the city of sabzevar. the average values of dry matter (dm), crude protein(c...

quality of protein fractions, according to cornell net carbohydrate and protein system (cncps), and digestibility coefficients, using tilley and terry procedure, of the fresh and ensiled amaranth (amaranthus hypochondriacus) forage were assessed. the concentration of crude protein (cp) and true protein (tp) in the fresh forage, were respectively 116 and 70 g/kg of dm. soluble protein (sp) and a...

this study was conducted to investigate the effect of physical and chemical processing on crude protein fractions of two varieties of canola (okapi and modena) and safflower (62 and zarfan) seed using cornel net carbohydrate and protein system and on protein subunits using sodium dodecyl sulfate polyacrylamide gel electrophoresis. formaldehyde was used as chemical treatment, while toasting and ...

The current ruminant feeding models require parameterization of the digestion kinetics of carbohydrate fractions in feed ingredients to estimate the supply of nutrients from a ration. Using an automated gas production technique, statistically welldefined digestion rate of carbohydrate, including soluble carbohydrate, can be estimated in a relatively easy way. In this study, the gas production d...

Concentrations of paralytic shellfish toxins (C1+2, B1, dcGTX2+3, dcSTX, GTX2+3 and STX) were determined by LC-FLD in composite samples of digestive glands of the cockle Cerastoderma edule and in each sub-cellular particulate fractions obtained after differential centrifugation (nuclei+debris, mitochondria, lysosomes and microsomes). The specimens were sampled during the exposure to a bloom of ...

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...

Red seaweeds are known sources of polysaccharides, some of which possess antiadhesive properties by inhibition of P-selectin-mediated leukocyte rolling. We here report the chemical composition and the antiadhesive activity of polysaccharide-rich fractions from the red alga Lithothamnion muelleri (Hapalidiaceae). The crude fractions enriched in polysaccharides B1 and B2 were obtained, respective...

In contrast with fractions from control animals, an aldehyde reductase, which catalyses the reduction of aflatoxin B1-dihydrodiol, in the dialdehyde form at physiological pH values, to aflatoxin B1-dialcohol, is expressed in cytosolic fractions prepared from rat livers bearing pre-neoplastic lesions, or following treatment with the anti-oxidant ethoxyquin. This expression parallels the developm...
