Bioavailability comparison between herbal methionine and DL-methionine on growth performance and immunocompetence basis in broiler chickens
BACKGROUND:Herbal methionine can be compared relative toDl-methionine with evaluation of bioavailability of this source ofmethionine. OBJECTIVES: An experiment was carried out todetermine the relative bioefficacy of herbal methionine (H-Met)®relative to DL-methionine (DL-Met) on performance criteria andimmunocompetence of Met sources in male broilers. Atotal of 160male broilers were fed a Met-d...
متن کاملReduction of methionine sulfoxide to methionine by Escherichia coli.
L-Methionine-dl-sulfoxide can support the growth of an Escherichia coli methionine auxotroph, suggesting the presence of an enzyme(s) capable of reducing the sulfoxide to methionine. This was verified by showing that a cell-free extract of E. coli catalyzes the conversion of methionine sulfoxide to methionine. This reaction required reduced nicotinamide adenine dinucleotide phosphate and a gene...
متن کاملMethionine Requirement and Commercial Methionine Sources in Growing Pigs
Methionine is a limiting amino acid in commercial swine diets and commonly supplemented as dry DL-methionine (DL-Met, 99%) or as liquid DL-methionine hydroxy analogue-free acid (liquid MHA-FA, containing 88% of active substance). New and intriguing research has been published in poultry and swine as to what is the nutritional effectiveness of liquid MHA-FA relative to DLMet, and what are the re...
متن کاملCerebral vascular dysfunction in methionine synthase-deficient mice.
BACKGROUND Methionine synthase (MS) catalyzes the folate-dependent remethylation of homocysteine to methionine. We tested the hypothesis that deficiency of MS impairs endothelial function in mice heterozygous for disruption of the Mtr gene, which encodes MS. METHODS AND RESULTS Plasma total homocysteine was similar in wild-type (Mtr(+/+)) and heterozygous (Mtr(+/-)) mice fed a control diet (4...
متن کاملEfficacy of DL-methionine hydroxy analog free acid and DL-methionine as methionine sources for pigs.
Two experiments were conducted to evaluate the efficacy of dietary DL-methionine hydroxy analog-free acid (MHA-FA, 88%) compared with DL-methionine (DLM, 99%) as Met sources in pigs. In Exp. 1, a total of 245 crossbred pigs (initial BW of 6.4 kg [SD = 0.5]) were allotted to 7 treatments in 7 replicates for an experimental period of 28 d. The basal diet (BD) was formulated to contain 17.5% CP an...
