Abstract The amino acid l -methionine is an essential and commonly used as a feed supplement in terrestrial animals. It less suitable for marine organisms because it readily excreted. also highly water soluble this results loss of the eutrophication water. To address these problems, dipeptide dl -methionyl- (trade name: AQUAVI Met-Met) has been developed dedicated methionine source aquaculture....

The objective of this research was to determine the effect different starters consisted dried whey and soy proteins with low anti-nutritive factors (ANFs) + amino acids (lysine methionine) on body measurements, biochemical parameters, feed consumption early-weaned female Holstein calves. Based starter, calves were divided into four groups: i) control (control starter), ii) E1 (starter added dry...

To investigate template effect on physicochemical properties of zeolite and enhance the molecular sieving properties, adsorption of methionine amino acid was studied by spectroscopic methods. Four zeolites such as methionine templated analcime, methionine templated zeolite P, N, N-dibenzyl N,N,N,N-tetramethylethylenediamine (DBTMED) templated analcime and free template analcime were synthesized...

a thin-layer chromatography method has been developed and evaluated for the separation and determination of lysine and methonine in a mixture of amino acids obtained from acid or enzyme hydrolysis of protein. the solvent systems were (a) ethanol-ether, (b) phenol-water, (c) ethyl methyl ketone-pyridine-distilled water-glacial acetic acid. procedures in all the three stages were in the same dime...

BACKGROUND We describe a case of a very unusual complication following a coiling procedure in which the patient developed transient unique cerebral and cerebellar lesions. Lesions were examined not only by magnetic resonance imaging (MRI) but also by positron emission tomography-computed tomography (PET-CT) and proton magnetic resonance spectroscopy ((1)H-MRS). CASE PRESENTATION A 33-year-old...

in order to investigate effect of methionine levels in starter diet on performance, immunity and blood parameter of arian broilers chickens during the starter period, a trial with 700 broiler chickens in a completely randomized design with 7 treatments, 5 replicates and 20 chicks in each experimental unit was performed. experimental groups were consisted of 0.38, 0.43, 0.48, 0.53, 0.58, 0.63 an...

the purpose of this study was to investigate the effect of feeding dietary soy protein and soy protein supplemented with methionine on lipids and lipoproteins content of blood in wistar rats. sixteen male and 16 female wistar rats with the initial live weight of 116 ± 6.3 and 115.8 ± 6.8 grams respectively, were fed by the isocaloric and isonitrogenous diets containing casein (20%), soy protein...

BACKGROUND:Herbal methionine can be compared relative toDl-methionine with evaluation of bioavailability of this source ofmethionine. OBJECTIVES: An experiment was carried out todetermine the relative bioefficacy of herbal methionine (H-Met)®relative to DL-methionine (DL-Met) on performance criteria andimmunocompetence of Met sources in male broilers. Atotal of 160male broilers were fed a Met-d...

the effects of chromium methionine supplementation on performance and serummetaboliteswere evaluated in broiler chickens.two experiments were conducted at22 oc, thermoneutral, (tn) and33±2 oc, heat stressed (hs) conditions. two hundred and eighty eight male broiler chicks (ross 308) were allocated to four treatments in a completely randomized design. treatments with 0 (control), 200, 400 or 800...
