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 study aimed to evaluate liver and breast muscle insulin-like growth factor I (IGF-I) and growth hormone receptor (GHR) gene expression between broilers fed different methionine levels and sources. Broiler chicks were 22 to 42 days old, distributed in 5 treatments (control diet, DL1 - 0.08% DL-methionine, DL2 - 0.24% DL-methionine, MHA-FA1 - 0.11% methionine hydroxy analogue-free acid, and ...

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 ...

DNA methylation influences the expression of some genes and depends upon the availability of methyl groups from S-adenosylmethionine (SAM). Dietary methyl groups derive from foods that contain methionine, one-carbon units and choline (or the choline metabolite betaine). Humans ingest approximately 50 mmol of methyl groups per day; 60% of them are derived from choline. Transmethylation metabolic...

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...
