Amino Acid Solution For Shrimp Grow Fast – Healthy

Amino acids (also known as Amino Acids) are the building blocks of proteins, so they contribute to the regulation of different traits in the activities of shrimp and plants. Therefore, amino acid biosynthesis is very important. However, the synthesis of amino acids in different living organisms is very different, it depends on the forms of nitrogen they can use. Let’s learn with BSF Smart Farm the effect & application of Amino Acid with Shrimp.

What Are Amino Acids?

Amino acids, also written as amino acids, are biologically important organic compounds containing amino and carboxylic acid functional groups, along with a specific side chain in each Amino Acid. The main elements of amino acids are carbon, hydrogen, oxygen, and nitrogen, and several other elements are present in the side chain of each amino acid.

According to Wikipedia

Amino acids, also known as amino acids, are biological organic substances made up of amino groups (NH2), carboxylic acids (COOH) and a certain side chain group (R group).

Amino acids include the main elements such as nitrogen, carbon, oxygen, hydrogen and a few other elements in the substituent of each amino acid. The structure of the amino acid molecule is composed of amino groups (left) and carboxylic acids (right), the R group in position depending on the type of amino acid.

Amino Acid Effect With Shrimp

Unlike higher plants that can synthesize all the amino acids needed by the body, animals can only partially synthesize and this ability is different in other animals. together. Higher vertebrates can synthesize some amino acids on their own, the amino acids that they cannot synthesize themselves are called irreplaceable amino acids, or essential amino acids. With essential amino acids, animals must get from outside food sources to feed their bodies.

The Role Of Amino Acids With Shrimp


  • Amino acids are the main components of protein molecules. By joining together in different bonds, they form molecules that differ in composition and properties. The nutritional value of a protein is determined by the relative quantity and quality of the different amino acids in that protein. Through the process of digesting protein, food is broken down into amino acids.
  • Amino acids from the intestines enter the bloodstream and into the tissues, where they are used to synthesize proteins specific to the body.
  • Without amino acids, the organism is also lacking, just as without raw materials, it is impossible to have a perfect product. Therefore, when it comes to amino acid nutrition, it is not enough to just pay attention to the protein content of the food, but also to pay attention to the irreplaceable and replaceable amino acid components in it. as the ratio between them.
  • The criterion for determining the biological value and physiological role of amino acids is their ability to maintain shrimp growth.
  • A few amino acids when lacking will cause shrimp to stop growing and lose weight even though other components of the diet are adequate. These amino acids are called essential or irreplaceable amino acids because they cannot be synthesized in the body or synthesized at a rate that cannot meet the body’s needs for which they must be taken in. Sufficient in food protein.
  • Animals can synthesize 10 or 12 amino acids out of a total of 20 commonly encountered amino acids. There are 8-10 types of amino acids that the body cannot synthesize, which are essential amino acids.

Essential amino acids and functions for Shrimp?


  • Glycine: is the simplest acid, participates in the formation of the colorant of hemoglobin Hemoglobin. Glyxin participates in the detoxification processes of Benzoic acid and Phenylaxetic acid, exchange of starchy and fat substances, Nucleic acids and Nucleotites.
  • For chicks, Glyxin is an irreplaceable amino acid. The inclusion of Glyxin in the feed ingredients of chicks will increase the transfer of amino acids in the tissues of the body, increasing the redox processes.


  • Threonine: An irreplaceable amino acid in the body, it participates indirectly in a series of changes for Glyxin.
  • When there is not enough threonine in the diet, the liver will become fatty, the animal will lose weight, stop growing, lose weight and die.


Cysteine: A sulfur-containing amino acid, when broken down, this amino acid has a detoxifying effect by oxidizing sulfur. This acid will bind with the poison to neutralize the toxicity.


  • Valine: This is an irreplaceable amino acid. When there is not enough Valine in the diet, animals will lose weight, especially chicks will die at 18-19 days. Valine is essential for the normal functioning of the nervous system.
  • In the case of Valine deficiency, animals will lose weight, have disturbances in coordination of movements and muscle weakness. Valine also has an effect on the functioning of the pancreas.


Leucine: This is one of the irreplaceable amino acids, necessary for building tissue proteins and for the functioning of the pancreas. Leucine has the effect of stimulating the activity of the circulatory system.


  • Isoleucine: This irreplaceable amino acid in the body will form glycogen and ketones.
  • In the diet without Isoleucine, the level of free amino acids in the tissues of the chicks will be changed rapidly, the chicken will die. In cases where this amino acid is not enough in the diet, animals also experience rapid weight loss.


  • Tryptophan: Also an irreplaceable amino acid. In the body, Tryptophan is converted into vitamin PP, which to a certain extent represents the nutritional value of food.
  • Pigs lacking Tryptophan will have poor appetite and hair loss. Piglets with growth retardation, swelling and peeling skin around the eyes, systemic eczema, diarrhea; Severe cases can cause necrosis of the large intestine, convulsions, loss of consciousness and eventually death.
  • Chicks lacking Tryptophan will suffer from black tongue disease, stop growing, eat less, develop poor feathers, and scaly dermatitis.


  • Arginine: is an amino acid that plays an important role in the formation of urea.Arginine has a positive effect in poultry production. Chicks are almost incapable of synthesizing Arginine.
  • This amino acid has an effect on calcium absorption, along with Glycine having an effect on feather growth in poultry.
  • Pigs also need Arginine for growth and development, lack of Arginine in feed will make pigs grow slowly and vitamin E metabolism disorder.


  • Histidine: Abundant in hemoglobin. With a lack of histidine, the hemoglobin level in the blood drops. Histidine plays an important role in the formation of hemoglobin. When necessary hemoglobin can be broken down to release histidine.
  • Decarboxylation
  • Hemoglobin → Histidine → Histamine
  • Histamine is a substance that plays an important role in dilating blood vessels. Deficiency or excess of histidine impairs conditioned functioning.


  • Lysine: Lysine is one of the most important amino acids. This is one of the three amino acids that receive special attention when assessing the nutritional quality of the diet (lysine, tryptophan, methionine).
  • Lack of lysine in food leads to disorders of hematopoiesis, lowering of red blood cells and hemoglobin. In addition, when lysine deficiency, protein balance is disturbed, muscle wasting, ossification process is disturbed and there are a series of changes in liver and lungs.
  • If there is not enough Lysine in the diet, pigs will lose weight, anorexia, dry skin. If Lysine is deficient, piglets from 3 to 6 months of age will have decreased blood alkalinity and serum protein.
  • If there is not enough Lysine in the feed, the pigmentation of feathers in chickens, ducks and pigs will be hindered. Feeding the chicks a diet without lysine resulted in only 53 days of survival.


  • Methionine: Methionine belongs to the class of sulfur-containing amino acids. The sulfur of methionine is more stable to alkalis than other sulfur-containing amino acids (cystine and cysteine).
  • Methionine plays an important role in material metabolism, especially in the process of attaching and exchanging methyl groups in the body. Methionine is the main source of volatile methyl groups in the body.
  • Methyl groups are used to synthesize choline, a highly biologically active substance.
  • Choline is also the most powerful fat synthesizer: preventing fatty liver. In addition, it has specific effects on lipid and phosphatid metabolism in the liver and plays an important role in the prevention and treatment of atherosclerosis.


  • Phenylalanine: Involved in the synthesis of tyrosine (a precursor to adrenaline) and is the main amino acid in the formation of thyroid protein.
  • In the diet without enough Phenylalanine, pigs will lose weight and increase feed costs.


When it comes to protein, people are not only interested in its content in food, but also pay attention to the amino acids that make up the protein (especially the composition and ratio of essential amino acids in protein). . Protein requirements, more precisely, are amino acid requirements. In addition to the main function of making proteins, they are also precursors of a number of other metabolic products. There are two types of amino acids: essential and non-essential.

Non-essential amino acids

Non-essential AAs are AAs that the body can synthesize on its own from food. These include: Alanin, Glycin, Serin, Tyrosine, Polin, Cysteine, Cystin.

Essential Amino Acids

The need for essential amino acids has been studied a lot because shrimp and fish cannot synthesize them and must be obtained from food. Like higher animals, aquatic animals in general need 10 amino acids, including: arginine, histidine, isoleucine, leucin, lysine, methionine, phenylalanine, threonine, tryptophan and valine (Halver, 1989).

Essential amino acid index (EAAI)

The essential amino acid index is calculated according to the following formula:


  1. aa1, aa2, …aan,    are the corresponding percentage of essential amino acids of the feed protein.
  2. AA1, AA2, …AAn,   are the percentages of essential amino acids, respectively, of fish and shrimp
  3. n: is the number of essential amino acids considered

Thus, with the calculation of EAAI as above, all 10 essential amino acids are interested. The higher this index, ie the EAA ratio of the protein in the feed is nearly equivalent to the EAA ratio of the protein in the body of aquatic animals, the more nutritional value that feed has to the animals.

The maximum EAAI index is 1, the minimum is 0.1. When this index is from 0.9 or more, the quality of protein is very good, if it is around 0.8, then it is okay, and less than 0.7, it does not satisfy the needs of the cultured subjects.

EAAI index of some feed ingredients for black tiger shrimp:

Shrimp meal (Acetes sp):    0.98

Toner powder:                     0.98

Peruvian fishmeal:              0.92

Tuna meal:                          0.92

Soybean meal:                    0.87

Casein:                               0.81

Sweet potato flour:             0.53
