Amino Acids

Amino acids are the building blocks of proteins and polypeptides that are the major component of animals’ muscles and tissues.

Amino acids are fundamental for animal nutrition. They are the building blocks of proteins and polypeptides that are the major component of animals’ muscles and tissues, and also form an important component in some fluids such as milk.

Their presence is necessary to maintain the normal structure and function of the intestine, and they are key in regulating metabolic pathways for improving health, survival, growth, development, lactation, and reproduction

The composition of amino acids in feeds is very variable, so it is important to closely monitor feed quality to ensure that animals are consuming appropriate amounts of amino acids to maintain their health and productivity while maximizing profitability.

So, from growth to production and reproduction, amino acids play a large part in the productivity of farm animals and can contribute significantly to the profitability of a farm.

Methionine

Reg. Number: V33840 ACT 36 of 1947

Methionine is an essential amino acid and, together with cystine, the only sulphur-containing proteinogenic amino acid.

Methionine is the first-limiting amino acid in poultry diets together with lysine, and the second- to fourth-limiting in pigs. As an important donor of methyl groups in metabolism, methionine is vital for optimum protein synthesis in growing animals and for feather development and laying performance.

As the precursor of other amino acids such as cysteine and taurine, versatile compounds such as SAM-e, and the important antioxidant glutathione, methionine plays a critical role in the metabolism and health of many species.  

All methionine sources are not created equal. The forms and types of amino acids available commercially vary not only in their methionine density, but also in uptake and response in the target animal. Bioavailability has a major bearing on the overall nutritional value of the amino acid product used.

Reg. Number: V24824ACT 36 of 1947

ALIMET® feed supplement is the methionine source that works better. It has 88% methionine activity and is 100% absorbed by the animal. But there is more.

The benefits of ALIMET® go beyond it being just a source of methionine, including:

  • Antioxidant effect in the feed
  • Maintained performance during heat stress
  • Energy savings in the feed mill
  • Increased feed intake 

Reg. Number: V23227 ACT 36 of 1947

MHA® feed supplement is the dry granular formulation of ALIMET® – the methionine source that works better. It has 84% methionine activity and is 100% absorbed by the animal. It is equally effective for poultry and livestock diets. Because of its dry granular powder form, it is the leading source of HMTBa inclusions in premixes and farm feed mills.

MHA® shares many of the same benefits of ALIMET® that go beyond it being just a source of methionine, including:

  • Antibacterial and antioxidant effects in the feed
  • Organic source of calcium
  • Maintained performance during heat stress
  • Increased feed intake

For ruminants, HMTBa

  • Is an effective source of methionine activity
  • Delivers a naturally occurring precursor of L-methionine called HMTBa.
  • The effect of HMTBa on improving microbial protein synthesis in the rumen and supplying methionine to the animal is promotion of milk, fat and protein yield in lactating cows.
  • During the close-up period, HMTBa alleviates dry matter intake depression and bolsters gain and feed efficiency in growing cattle.
  • As the world’s most popular liquid methionine solution, using ALIMET® provides producers with better blending and handling than DL-methionine products.
  • MHA mixes and handles easily in the mill and can be incorporated at any level in straight mineral mixes and protein mixes or with products high in fat, such as propylene glycol.

Lysine

Reg. Number: V33843 ACT 36 of 1947

Lysine is a key nutrient related to the production performance and is considered as the first or second-limiting amino acid in a typical cereal- or soy-based diet for most species.
Lysine is an α-amino acid that is a precursor to many proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain lysyl, classifying it as a basic, charged, aliphatic amino acid.

Reg. Number: V33842 ACT 36 of 1947

L-Lysine HCl is produced by microbial fermentation (Corynebacterium Glutamicum) with natural raw materials(raw sugar, beet molasses, cane molasses, or SOD) which helps to improve performance of animals and to lower user production cost.
Lysine 70 is produced by microbial fermentation (Corynebacterium Glutamicum) from natural raw materials of agricultural origin (such as beet molasses or SOD). Lysine 70, the sulphate salt of lysine along with fermentation by-products, is 55% L-Lysine (as Free-Lysine). It does not only contain lysine but also by-products, such as essential amino acid and carbohydrate. Lysine 70 can be used instead of traditional L-Lysine HCl as a livestock feed additive. It has almost the same feed effects as Lysine HCl, such as feed efficiency, true digestibility coefficient, bioavailability and RBV (relative biological value).

Threonine

Reg. Number: V33844 ACT 36 of 1947

Threonine is an amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, a carboxyl group, and a side chain containing a hydroxyl group, making it a polar, uncharged amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet.
Threonine is an essential amino acid for monogastric animals. In pigs, it is the second-limiting amino acid after lysine in cereal/soy-based diets.
Apart from its role in protein biosynthesis, threonine has important functions in the digestive process by being a major component of the gut mucus. Moreover, threonine is a significant building block of the immunoglobulins.

Valine

Reg. Number: V33846 ACT 36 of 1947

Valine is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a side chain isopropyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet.
Valine is an essential amino acid and belongs, together with isoleucine and leucine, to the group of branched-chain amino acids. Valine is the next limiting amino acid after lysine, threonine, methionine, and tryptophan in pig nutrition, especially in protein-reduced diets. Addition of valine to the diets of growing pigs will open up the full growth potential of modern, high-performance pigs with their increasing requirements in protein quality, and contributes to reducing nitrogen emissions.

Isoleucine

Reg. Number: V33846 ACT 36 of 1947

Isoleucine is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group, an α-carboxylic acid group, and a hydrocarbon side chain with a branch. It is classified as a non-polar, uncharged, branched-chain, aliphatic amino acid
L-Isoleucine, as one of the branched-chain amino acids, is involved in body composition and regulation of protein metabolism, promoting healthy growth. L-Isoleucine, together with L-Valine, is generally considered as the next limiting amino acid in low crude protein diets while optimising the efficiency of feed.

Tryptophan

Reg. Number: V33845 ACT 36 of 1947

Tryptophan is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent.
Tryptophan is the fourth-limiting amino acid after lysine, threonine, and methionine in pigs. In addition to its effect on protein synthesis, L-Tryptophan plays a specific role in other physiological processes, for example, being a precursor of niacin or of the neurotransmitter serotonin, which is involved in feed intake regulation.

Glycine

Reg. Number: V33841 ACT 36 of 1947

Glycine is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid, with the chemical formula NH₂‐CH₂‐COOH. Glycine is one of the proteinogenic amino acids.
