Effects of sodium selenite (SS) in offspring of broiler breeders has been reported, but the comparison between SS and different level of methionine on offspring has received limited, so this study was conducted to investigate sodium selenite and methionine effects on concentration of selenium in egg and serum of Iranian native broiler breeders. An experiment was conducted in 3 × 3 factorial exp...

essential amino acids such as methionine have been increasingly included into diets of lambs. however, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. to address this question, 21weaned male rahmani lambs were allotted to 3 dietary treatments: control diet (c), control diet plus 3.30 g of methionine/kg con...

this research was conducted to evaluate the effects of synthetic methionine replacement with herbal methionine (hm) on performance, blood biochemical parameters and carcass characteristics in broiler chicken. a total of 280 8-old ross 308 male chicken were randomly assigned to 7 dietary treatments: control, in which 100% methionine requirement was supplied form dl-methionine, and in treatments ...

background: the degree to which the amount of aningested nutrient is absorbed and available to the body is calledbioavailability. objectives: relative effectiveness of herbalmethionine (h-met®) compared to dl-methionine (dl-met)was investigated in this experiment. methods: exponentialregression analysis was used to determine bioefficacy of h-met®based on body weight gain, feed intake and feed c...

Abstract The precise regulatory role in protein synthesis by facilitating interactions with mRNA codons for various tRNA modifications is unclear. We previously reported that enhanced green fluorescent (GFP) reduced GFP expression human methionine-conjugated initiator (tRNAi)/tRNA synthetase pairs under methionine-deficient conditions. Here, we investigated the effect of non-formylated Escheric...

Background: The search for potent radioprotective agents for the amelioration of radiation side effect is an important aim in radiobiology. The present study aimed to evaluate the effects of curcumin and seleno-L-methionine against radiation-induced micronucleus formation in rat bone marrow.Methods: In total, 40 male rats were divided into 8 groups (n=5 each), including control, curcumin or sel...

in order to determination the methionine requirement 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 units was performed. experimental groups were consisted of 0.38, 0.43, 0.48, 0.53, 0.58, 0.63 and 0.68  % of methionine. other amino acids provided higher ...

background : increased level of serum homocysteine is one of the risk factor of atherosclerosis. its production related in some sulfur amino acids such as methionine. some important cofactors that are involved in metabolic pathways of this amino acid are folate and vitamin b12. we have assessed the status of methionine, folic acid, and vitamin b12 in some coronary atherosclerotic male patients....

Amino acid dehydrogenases (L-amino acid: oxidoreductase deaminating EC 1.4.1.X) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either NAD+, NADP+ or FAD. These enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...
