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 ...

The Deepwater Horizon oil spill of 2010 raised concerns that dispersant and dispersed oil, as well as crude oil itself, could contaminate shellfish and seafood habitats with hazardous residues that had potential implications for human health and the ecosystem. However, little is known about the effects of crude oil and dispersant on the human fecal microbiota. The aim of this research was to ev...

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 ...

Nitrogen losses from dairy production have negative impacts on the environment and on production economics. In Northern Europe, dairy cattle are mainly fed forage-based diets supplemented with protein feeds such as rapeseed meal. This thesis sought to develop and evaluate new methods for forage protein evaluation and to improve the value of locally produced protein feeds. Ruminal metabolism of ...

Though bad odour has always been associated with animal production, it did not attract much research attention until in many countries the odour production and emission from intensified animal production caused serious nuisance and was implicated in the health problems of individuals living near animal farms. Odour from pig production facilities is generated by the microbial conversion of feed ...

In this study, the effects of mixed silage on fermentation quality, chemical composition and bacterial communities corn straw soybean were assessed. Corn straws, straws or a mixture in 1:1 mass ratio uniformly processed using same method to produce bagged weighing 50 kg per bag. At days 0, 14 60 process, nutritional quality indicators each group measured. A complete factorial design assess effe...

Norman Wells crude oil was fractionated by sequential alumina and silicic acid column chromatography methods. The resulting nitrogen-rich fraction was analyzed by gas chromatography-mass spectrometry and showed 26 alkyl (C(1) to C(5)) carbazoles to be the predominant compounds. An oil-degrading mixed bacterial culture was enriched on carbazole to enhance its ability to degrade nitrogen heterocy...

Most cellulolytic enzyme blends, either procured from a commercial vendor or isolated from a single cellulolytic microbial secretome, do not efficiently hydrolyze ammoniapretreated (e.g., ammonia fiber expansion, AFEX) lignocellulosic agricultural crop residues like corn stover to fermentable sugars. Typically reported commercial enzyme loading (30–100 mg protein/g glucan) necessary to achieve ...
