The concentration of Cr in several tissues in response to high-level, short-term supplementation was used to determine the relative bioavailability among 4 organic Cr sources and to assess the relative safety of high levels of supplementation. Crossbred pigs (n = 40; mean BW = 48.1 +/- 0.9 kg) were allotted to 5 diets: a control diet with no added Cr, or 5,000 microg/kg of Cr from Cr tripicolin...

the effect of3levels of methionine (nrc recommended, 5 percent more than nrc recommended and 10 percent more than nrc recommended) and 2 levels of fat (0 and 5 percent) on some economical traits (performance and carcass) of broilers using a 2x3 factorial experiment with completely randomized design based on two rearing stages, starter (0-3 wk) and grower (4-6 wk) was studied. anova of the effec...

Hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (VI) or chromium nitrate chromium (III). Although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues of rice seedlings exposed to chromium (III) than those in chromium (VI), majority being in...

the aim of this study was to evaluate the effects of balancing low protein diets for methionine and lysine on performance of early lactation holstein cows under hot environmental temperature. twenty one multiparous holstein cows in early lactation were allocated to three experimental rations including, 1) high protein ration with 17.5% cp, 2) medium protein ration with 16% cp and 12 g/d rumen p...

The Cover Feature shows a metal nanoparticle modified with the amino acid L-methionine and adsorption of enzyme acetylcholinesterase (AChE) on methionine-capped surface. Methionine-capped Ag Au nanoparticles (NPs) were tested as inhibitors AChE, they showed moderate inhibitory potential toward AChE. NPs are much larger than molecules cannot enter active site gorge, so inhibition occurs by block...

Chromium-VI would impose detrimental effects morphological, physiological, and metabolic in plants. This study aimed to research the impact of citric acid (0, 2.5 and 5 mM), on different the morphological and physiological characteristics of garden cress exposed to chromium-VI stress (0, 1, and 10 mM). Results showed that some growth parameters, chlorophyll, carotenoids, and DPPH activity decre...

OBJECTIVE A systematic review of the effect of chromium supplementation on glucose metabolism and lipid levels. RESEARCH DESIGN AND METHODS A literature search was conducted in MEDLINE and the Commonwealth Agricultural Bureau. Eligible studies were English language randomized controlled trials of chromium supplement intake > or = 3 weeks, with > or = 10 participants receiving chromium. All tr...
