Two trials were conducted in order to examine the effects of level of supplemental methionine on productive performance, dietary energetic, plasma amino acid concentration, and digestive function.
The objective of this study was to determine the effects of chromium methionine (Cr-Met) chelate supplementation on blood metabolites and fatty acid profile of beef from Holstein steers during late fa...
The aim of this study was to determine the effects of curcumin, ellagic acid and methionine on sperm parameters following the freeze-thawing of Merino ram semen. Ejaculates were collected via an artif...
This study was conducted to determine the effect of dietary supplementation of liquid DL-methionine hydroxy analog free acid (DL-MHA) on growth performance and gastrointestinal conditions of piglets. ...
A 2×5 factorial experiment, using 2 dietary methionine levels (0.28% and 0.48%) and 5 dietary choline levels (0, 394, 823, 1,239, and 1,743 mg/kg), was conducted to study the effects of dietary methio...
The population of Lactobacillus spp. in the caecum was decreased by both DLM and LMA supplementation (P < 0.05). Succinic acid concentration in the caecum of pigs fed the DLM diet was greater than...
Three experiments (EXP) were conducted using two hundred seventy male chicks Ross 308 in each (90 cockerels per treatment; 3 replications, 30 chickens per pen) for 42, 38 and 35 days. The basal diets ...
The objective of this study was to evaluate the effect of dietary supplementation of antibacterial peptide and zinc methionine on performance and some serum biochemical parameters of weaned piglets. R...
The objective of this study was to determine the effect of supplemental lysine (Lys), methionine (Met) or both amino acids added in the form of rumen-protected (RP) tablets with copolymer coating to a...
An experiment was conducted to evaluate the effect of ruminally protected methionine (Mepron? Degussa AG, Germany) in dairy cows. Three weeks before calving 36 cows (Holstein and Czech Fleckvieh breed...
The objectives of this study were to investigate the immune responses of broiler chickens fed diets supplemented with different level of chromium methionine (CrMet) in heat stress (HS) condition. Two ...
The limiting sequence and relative ratio of lysine (Lys), methionine (Met), and threonine (Thr) for calves about 2 mo of age fed milk replacers (MR) containing soy protein are not clearly defined. The...
In this experiment, the factors were control and low energy concentration (2800 vs. 2600 kcal ME/kg), control and deficiency methionine concentration (0.40 vs. 0.35%), and control and excess folic ac...
Two experiments were conducted to determine the effects of adequate or marginal excess of dietary DL-2-hydroxy-4-(methylthio) butanoic acid (MHA) on productive performance and inflammatory response in...
Role of Dietary Methionine in Poultry Production     growth  heat stress  immune  methionine  poultry       font style='font-size:12px;'> 2009/7/29
Synthetic DL-methionine (DLM) supplements poultry diets to enhance production. The bioefficacy of liquid methionine is generally lower than that of powder methionine; however, if the level of total s...
