two experiments were conducted to evaluate the crude protein fractionation, in vitro gas production and the biological effects of tannins in alfalfa silage treated with different levels of pistachio by-products (pb) extract. pb was soaked in water with a ratio of 1:5 (w/v) for 12 h. after filtering and concentrating, the crude extract was added to fresh alfalfa to a final concentration of 1%, 2...

this study was carried out to determine the effects of gamma irradiation on dry matter (dm) and on crude protein (cp) degradation of rapeseed meal, using nylon bags and sds-page techniques. ruminal nylon bags of either untreated or irradiated rapeseed meal at doses of 25, 50 and 75 kgy were suspended in the rumen of four non-lactating holstein cows for up to 48 h. intestinal crude protein diges...

I. In the wild, red grouse live largely on heather, a high-fibre (25 :(,), low-protein (7 %) food. Digestibility trials were carried out under semi-natural conditions, with magnesium as a digestibility marker. T w o trials w-ere done, one in autumn and one in spring. 2. Digestibility of the dry matter varied from 21 to 30 ”/o and metabolizable energy from 1.1 to 1.6 kcal/g. Thcse variations wer...

Abstract Cowpea protein isolate (CPI) was subjected to various dry and wet heat pretreatments followed by sequential digestion with pepsin pancreatin; the undigested residues were isolated as indigestible cowpea proteins (ICPs). All ICPs exhibited in vitro bile acid-binding capacity but ICP from slow cooling-induced gelation had highest yield (68%) used for rat feeding experiments determine eff...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...

brachystegia eurycoma is predominantly grown in the eastern region of nigeria. its seed is used in food majorly as a soup condiment, flavouring agent and soup thickener. the proximate, mineral and amino acid compositions were determined on raw and processed seeds (boiled, fermented and roasted) using standard analytical techniques. the processing methods showed deviations in nutrients from the ...

this study aimed to assess the anticariogenic and hemolytic activity of crude plant seed protein extracts against tooth decaying bacteria.the proteins from seeds of 12 different plants were extracted and used for antimicrobial assay against six different organisms. the extraction was carried out in 10mm of sodium phosphate buffer (ph 7.0). protein concentrations were determined as described by ...

There is a relationship between the normal progress of digestion and the retention or elimination of the proteins ingested with the meal by Aedes aegyti females. The addition of soybean trypsin inhibitor (STI) to a protein meal prevented digestion and resulted in a rapid elimination of the undigested proteins. The addition of a mix of free amino acids to a protein meal together with STI resulte...
