an experiment was conducted to reevaluate the digestible lysine requirement of arian male broilers by comparing the performance of chicks fed different levels of cottonseed meal (csm) on a total amino acid (aa) versus a digestible aa basis. four hundred and thirty two (432) arian male broiler chicks were allotted to 18 treatments with four repli-cates of six chicks each in a completely randomiz...

objective(s) motility plays a major role in pathogenicity of helicobacter pylori, yet there is  scarce data regarding its chemotactic behaviour. the present study was designed to investigate the chemotactic responses of local isolates of h. pylori towards various sugars, amino acids, as well as some other chemical substances. materials and methods chemotaxis was assayed by a modified adler’s me...

addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.

caviar is one of the valuable and most popular fish products all over the world that are obtained from sturgeons. nowadays, the wild resources of these fishes are diminished, therefore, to meet the demand for the product, farming sturgeons has been considered. the chemical composition and the amino acids profiles of the wild and farmed roe obtained from beluga (huso huso) were compared and the ...

an experiment was conducted to determine the dietary digestible lysine requirement of male and female broiler chickens (arian) during the period from 6 to 21 days post-hatching. an amino acid-fortified basal diet containing corn and soybean meal as intact protein sources provided 20 % cp, and 3200 kcal amen / kg. in this experiment 150 male and 150 female chicks were allocated on the basis of b...

abstract        background and objective: measurement of amino acids is an important tool for metabolic studies and evaluation of patients’ clinical condition. the aim of this study was to analyze the plasma amino acids using reverse phase high performance liquid chromatography techniques (rp-hplc) with pre-column derivatization by o-phthalaldehyde (opa) in combination with 3- mercaptopropionic...

amino acids (aa) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. although, some table values are available on amino acids requirement, aa requirements may vary due to changes in dietary composition and breeding selection. thus amino acids requirements have remained an ongoing research topic. ...
