Methionine Requirement and Commercial Methionine Sources in Growing Pigs
نویسندگان
چکیده
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 reasons for the difference. However, experiments are not always conducted in a “meaningful” way, or data are sometimes analyzed incorrectly. In the present paper, relevant study requirements and new scientific data on relative effectiveness of methionine sources in pigs are summarized and discussed.

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...

This study was conducted to investigate the effect of dietary chromium-methionine (Cr-Met) supplementation on growth performance, feeding behavior and physiological responses of Holstein male calves during two different phases of body weight (BW). Twenty six (153.5±9.83 kg of BW) male calves were divided in two groups (n=13) and randomly assigned to treatments: 1) control and 2) Cr-Met (1.1 mg ...
متن کاملComparative toxicity of selenium from seleno-DL-methionine, sodium selenate, and Astragalus bisulcatus in pigs.
Selenium is an essential micronutrient, although ingestion in excess in pigs can cause disease conditions including neurological dysfunction and chronic skin and hoof lesions. Controlled feeding trials in growing swine, using the same Se content in feed sources, resulted in higher concentrations (p < or = 0.05) of Se in blood and organs of pigs fed seleno-DL-methionine compared with those recei...
متن کاملA Methionine Deficient Diet Enhances Adipose Tissue Lipid Metabolism and Alters Anti-Oxidant Pathways in Young Growing Pigs
Methionine is a rate-limiting amino-acid for protein synthesis but non-proteinogenic roles on lipid metabolism and oxidative stress have been demonstrated. Contrary to rodents where a dietary methionine deficiency led to a lower adiposity, an increased lipid accretion rate has been reported in growing pigs fed a methionine deficient diet. This study aimed to clarify the effects of a dietary met...

The objective of this study was to determine the optimum ratio of methionine to methionine plus cystine for growing pigs. A nitrogen balance trial was conducted using a total of 21 barrows (Large White×Landrace) over two replicates. The initial body weight was 20.36±1.22 kg (mean±SD) in the first replicate and 23.54±1.02 kg (mean±SD) in the second. For each replicate, the 21 pigs were randomly ...
