Antioxidant astaxanthin in composition of sturgeon feeds

چکیده
The article highlights the experience of using astaxanthin in sterlet feeding. Studying influence on morphophysiological state fish helps develop highly effective recipes compound feeds for valuable objects aquacultures. This intense antioxidant impacts work all systems and overall health, but feeding has not reffered to aquaculture facilities. physiological status sturgeons been studied. It was found that test No. 2 (adding 40 mg per 1 kg feed), highest absolute growth, average daily growth rate mass accumulation coefficient (p ˂ 0.001) were observed, contrast 20 feed) control. Absolute increase this sample certain 2.3 times higher than control one. variant made 1.8%, which is group 0.001). data obtained indicate positive effect (40 mg/kg) fish–breeding biological indicators cultivated fish. energy metabolism also prove a better plastic substances experimental groups (tests No.1 No.2): hemoglobin variants with adding feed 77.4 71.3 g/l, 17.6 8.4% group. In compared level total protein by 17.4 22.2% < 0.05). Thus, it can be said provided more favorable trophic biochemical conditions necessary normal development

Antioxidant activities of astaxanthin and related carotenoids.
The antioxidant activities of astaxanthin and related carotenoids have been measured by employing a newly developed fluorometric assay. This assay is based on 4,4-difluoro-3,5-bis(4-phenyl-1, 3-butadienyl)-4-bora-3a,4a-diaza-s-indacene (BODIPY 665/676) as an indicator; 2,2'-azobis-2,4-dimethylvaleronitrile (AMVN) as a peroxyl radical generator; and 6-hydroxy-2,5,7, 8-tetramethylchroman-2-carbox...
متن کاملAntioxidant role of astaxanthin in the green alga Haematococcus pluvialis
The green unicellular alga, Haematococcus pluvialis has two antioxidative mechanisms against environmental oxidative stress: antioxidative enzymes in vegetative cells and the antioxidative ketocarotenoid, astaxanthin, in cyst cells. We added a reagent that generates superoxide anion radicals (O2 ), methyl viologen, to mature and immature cysts of H. pluvialis. Tolerance to methyl viologen was h...
متن کاملAntioxidant effect of astaxanthin on phospholipid peroxidation in human erythrocytes.
Phospholipid hydroperoxides (PLOOH) accumulate abnormally in the erythrocytes of dementia patients, and dietary xanthophylls (polar carotenoids such as astaxanthin) are hypothesised to prevent the accumulation. In the present study, we conducted a randomised, double-blind, placebo-controlled human trial to assess the efficacy of 12-week astaxanthin supplementation (6 or 12 mg/d) on both astaxan...

Nephrolithiasis one of the most prevalent and widely studied of renal diseases. No remedy has proved to be completely effective in alleviating the renal damage caused by kidney stones. The most common type of kidney stones is calcium oxalate stones which are composed mainly of calcium oxy monohydrate crystals. This study has been carried out to evaluate the effect of the xanthophyll carotenoid ...
