Physiological and Biochemical Aspects of Methionine Isomers and Precursors in Broilers
Methionine (Met) is an essential amino acid for animals and also the first limiting amino acid in a broiler diet. The dietary supplemental Met sources include the natural isoform L-methionine (L-Met), the synthetic form DL-methionine (DL-Met) and the synthetic Met precursor DL-2-hydroxy-4 …

Formulation and characterisation of novel films for buccal mucosa drug delivery for paediatric patients
… different film forming polymers hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), sodium alginate (SA), carrageenan (CA) and metolose (MET) were used initially and subsequently with polyethylene glycol (PEG 400) as plasticiser and L-arg (to stabilise OME). Polymeric gels (1% w/w) were …

Nutritional strategies to control clostridium perfringens in gastrointestinal tract of broiler chickens
… examined the effect of various levels of DL-Met or MHA-FA on C. perfringen and other intestinal microbes. These experiments demonstrated a significant reduction (P < 0.05) in C. perfringen growth with methionine supplementation in ileum and cecum. The results suggest that both DL-Met and …

An evaluation of supplemental methionine sources for lactating dairy cows
<p>The most effective method for increasing supplies of MP-Met to dairy cows to increase milk protein production is to feed rumen-protected Met ( RP-Met) products; however, not all RP-Met products are absorbed by the dairy cow in the same manner. Universally acceptable methods must be developed to …

Carbohydrate sources and maximizing the use of supplemental amino acids in diets for weanling pigs
… maximum level of supplemental L-Lys, along with DL-Met, L-Thr, and L-Trp that can be added in diets for 6- to 12 and 13- to 23-kg pigs. Three experiments were conducted to compare the feeding value of MCP (20% lactose and 60% sugars) and DW (70% lactose). Results from these experiments indicate …

Factors Affecting Deficiency and Toxicity of Sulfur-Containing Compounds
… of acid-base balance. Thus, excess Cys led to metabolic acidosis within 12 hours of feeding and was ultimately lethal. The growth depressive and lethal effects observed in chicks consuming 2.5% excess Cys were ameliorated through provision of dietary potassium bicarbonate and hydrogen peroxide, …

Sulfur amino acid nutrition of the young pig
… Pigs were ad libitum fed in all experiments. A methionine (Met)-deficient feather meal-corn-soybean meal-dried whey basal diet (20% protein, 3250 kcal ME/kg, 0.19% Met, 1.00% cystine (Cys), 0.11% choline) was used to determine the Met and SAA requirements and to evaluate the utilization of Met …
