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...

A feeding trial was carried out to determine the effects of chromium methionine (Cr-Met) chelate and forage level over two years, 1(st) fattening and 2(nd) fattening period on growth parameters, carcass characteristics and blood metabolites of 46 Korean native (Hanwoo, Bos Taurus, BW = 183 ± 44 kg) steers. Treatments were: 1) Steers in the low forage (LF) group were fed diets that consisted of ...

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...

Sorption data were obtained with a Matawan soil and the following chromium (III) organic complexes: chromium (III) ascorbate, chromium (III) glutamate, chromium (III) histidine, chromium (III) mandelate, chromium (III) citrate, chromium (III) cysteine, chromium (III) serine, chromium (III) pyruvate and chromium (III) oxalate. The influence of pH (2-12), ionic strength (0.005-1 M) and concentrat...

Chromium (Cr) is an essential trace element for humans (Anderson, 1992) and laboratory animals (NRC, 1997). It is the trivalent form of the molecule that is active biologically, the hexavalent form is actually toxic to many animal cells (NRC, 1997). Chromium acts through a protein, once named glucose tolerance factor (GTF), now more commonly referred to as the glucose transporter. This protein ...

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 ...

We have isolated a vesicular stomatitis virus (VSV)-specific CD4+ CD8- murine T-cell clone. This clone proliferates only in response to VSV and lyses infected tumor cells bearing class II major histocompatibility antigens in short-term chromium release assays. In addition, the cell has VSV antigens on its surface and is capable of killing uninfected tumor cells without major histocompatibility ...
