DL Methionine feed grade Unisplendour Methionine

Methionine is an essential amino acid in all animal species. Methionine is clearly recognised as the first limiting amino acid in poultry, and probably also in high-yielding cows, and as the second or third limiting amino acid in pigs fed conventional diets. Supplementation of appropriate amounts of methionine and methionine analogues to meet requirements is safe for the target species. The earliest signs of a critical overdose are reduced feed intake and weight gain. The level of supplementary methionine and its analogues that is toxic varies from species to species and depends on the basal diet and its content of sulphur-containing amino acids.

Methionine from DL-Met and its hydroxy analogue and their salts is incorporated in the protein of tissues and products, showing a constant amino acid pattern. Consequently, the use of these additives will not result in an increased methionine content in tissues and products. Doses exceeding the requirement will be excreted.

Residues present in the animal tissues and products resulting from the extremely small quantities of free styrene and 2-vinylpyridine found in DL-Met-cop are very unlikely to raise concerns about consumer safety.

None of the products are considered to present a significant inhalation risk. DL-Met, DL-Met-cop and DL-Met-ec are considered non-irritant to skin and eyes, and the lack of sensitisation potential demonstrated for DL-Met is considered to apply also to DL-Met-cop and DL-Met-ec. DL-Met-Na is considered corrosive to skin and eyes and harmful if swallowed. HMTBa is an irritant to the skin and corrosive to the eyes but is not a dermal sensitiser. HMTBa-Ca is irritant to the eyes but not to the skin. The absence of a dermal sensitisation potential demonstrated for HMTBa is considered to apply also to HMTBa-Ca. HMTB-i is non irritant to the skin and eyes, and it is not a dermal sensitiser.

Amino acids and intestinal health

A weaned piglets, intestinal broad reshaping occurs to shift to adapt to solid feed from the liquid feed. The stage adaptation of nutritionists constitute a significant challenge, they must consider how to help the transition to solid feed pigs, but also to meet the expected costs.

From the perspective of an amino acid, reduce intestinal pressure while reducing the cost of the diet is an important strategy is an amino acid added to reduce rations by reasonable crystalline crude protein content. Reducing the crude protein content reduces the amount of the large intestine can ferment proteins, which would reduce the incidence of post-weaning diarrhea. This will also reduce the demand for protein sources, such as soybean meal, which will constitute the intestinal immune challenges, while also reducing the amount of some expensive protein sources. Early weaned pigs total lysine levels often configured as 1.65 to 1.7% or higher. At low levels of lysine (1.35% standardized ileal digestible (SID) lysine or 1.5% of total lysine) can reduce the need for expensive protein sources, but on pig performance is small.

When the low-lysine diets SID when other amino acids relative to lysine ratio is very critical. Other amino acids relative to the proportion of lysine, methionine plus cysteine ​​was 58%, 62% threonine, valine 65%, isoleucine 52% (if the blood product usage is high, then the percentage should be 60%). Tryptophan ratio of lysine remains controversial, recommended ratio is between 16.5 to 20 percent, depending on the level of nutrients as well as the specific experiment. A particular amino acid (e.g. arginine or glycine, and glutamic acid) seem to be able to meet the needs of the non-essential amino acids, and for the development of the intestinal tract has the intended effect.

Classification of amino acids in pig feed and its role

Amino acids are the basic unit composed of protein, it is divided into two major categories of essential and non-essential.

Essential amino acids the body can not be a hog or synthetic slow and can not meet the needs of pigs, it must be supplied by the diet.

The pigs required 10 kinds of essential amino acids, namely lysine, methionine, tryptophan, arginine, threonine, valine, histidine, leucine, isoleucine, phenylalanine .

Lysine, methionine, threonine and tryptophan are growing pig diets in the first four limiting amino acids. Pigs various stages of growth of these four kinds of amino acid requirements have been fully understood. The four mature crystalline amino acids and synthesis of synthetic technology has been able to meet the needs of commercial applications, and so that by adding synthetic amino acids. The typical corn - soybean meal crude protein content in pig diets reduced about 2%, the net can be increased by 2%. The study shows that, despite the low protein diet so that the carcass become fat trend. However, to maintain the original pig performance.

Ration of feed ingredients consisting of lysine present, egg + cystine, the relative lack of threonine, tryptophan, reducing the production of feed utilization and performance of animals. Therefore, you should add the appropriate amino acid in pig feed according to the type of diet.

DL- Metionina

DL- Metionina , es sintetizado a partir de materias primas petroquímicas, usando un conocido proceso de carbonato 
Este sistema de prueba compleja da como resultado un producto de alta calidad sin la formación de residuos de sal, evitando así, en gran medida la contaminación por los residuos del aire y el agua.

Particularmente para uso en nutrición de animales monogástricos. DL Metionina de grado feed, asegura el suministro adecuado de aminoácidos azufrados, especialmente de la metionina esencial . Siendo la metionina el primer limitante en la dietas típicas de las aves de corral, su uso ha sido bien establecido por muchos años. El uso en las dietas para lechones y cerdos en crecimiento pueden mostrar una considerable eficiencia con la metionina, especialmente cuando es formulada para lograr excreción de baja de nitrógeno por razones ecológicas, tales deficiencias pueden ser convenientemente compensadas usando DL Metionina de grado feed.
