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 Methionine Brief Introduction

DL-Methionine is biological protein synthesis skeleton amino acids. DL-Methionine is the necessary growth factors in livestock animal. It can also regulate animal’s metabolism. It is already widely used in feed, medicine, food and cosmetics, etc. In the feed industry, the maximum dosage is DL-Methionine. It is used to strengthen feed nutritional. If you add 1kg DL-Methionine in feed, and its nutritional value correspond to 50kg fish powder. DL-Methionine addition was 0.5%—0.2% in the feed. In the medicine area, DL-Methionine is the major element in aminophenol transfusion and compound amino acids. And also can used in synthetic medicinal vitamin. DL-Methionine has anti-fatty liver effects can be used to produce liver drug. In the food area, DL-Methionine is used for food’s amino acids and health food processing. And also used as nutrition supplement.

Storage: Store in a cool, dry, ventilated warehouse. When storing large goods, you should install conductive balance equipment, and prevent the accumulation of static electricity charge.

The concept of ideal protein

Amino acids which are essential cannot be synthesized by the animal and therefore must be provided by the diet. When the supply of one of these essential amino acids does not meet the animal’s requirement for this amino acid, it is said to be limiting. This limiting amino acid is limiting the potential growth of the animal. Once the limiting amino acid is covered via the feed, the next amino acid will become limiting (second limiting amino acid, third limiting amino acid, etc). Therefore the goal is to know the exact requirement of the animal for every essential amino acid in order to supply this amount to the animal via the diet. This is what is called the ideal protein concept. In practical diets, lysine is the first limiting amino acid. Therefore we always express the requirement of all essential amino acids as a ratio to lysine.

Amino acids can be supplied by the diet via feedstuffs (cereals, soybean meal, etc). The amino acid pattern (ratio of essential amino acids to lysine) in protein feedstuffs is not exactly in line with the requirement of the animal (the ideal protein). Protein feedstuffs are too low in the first limiting amino acids. If we would supply all essential amino acids via raw materials we would have to supply very high levels of crude protein. Because not all protein will be used, the surplus will be excreted by the animal. This surplus of protein has a negative impact on the animal’s health (surplus protein will be used by pathogenic bacteria in the large intestine and can cause intestinal disorders) and has a negative impact on the environment (nitrogen excretion).

Why add methionine and lysine into pig feed

Now much of the world's farm takes corn - soybean meal in the diet,  lysine and methionine are the first and second limit amino acids for pigs, so it need to be add extraly.

Essential amino acids in pigs include lysine, methionine, tryptophan, phenylalanine, leucine, isoleucine, valine, threonine. Soybean meal is rich in lysine and tryptophan, methionine and corn containing more so with corn and soybean meal, amino acids complementary to achieve better nutritional balance.

Because of lack of essential amino acids, the protein synthesis reduce body, causing a series of body protein metabolism, enzymes synthesis problems, the most important manifestations of growth retardation, and even lead to metabolic diseases.

Lysine is mainly used for protein deposition, are rarely involved in the regulation of metabolic processes. The role of methionine complex, in addition to protein deposition, but also closely related to the in vivo metabolism of sulfur-containing compounds, in addition to also use its methyl brought on poisons or drugs played a role in methylation and detoxification.

Metionina

En su forma natural la L-metionina es un aminoácido proteinogenico. Es uno de los aminoácidos esenciales y no puede ser sintetizados por el propio organismo. Por lo tanto, su ingesta adecuada a través de la dieta o mediante los suplementos alimenticios es de crucial importancia.

Compuestos de azufre están presentes en todos los seres vivos y tienen una variedad de funciones. Junto a la cisteína, la metionina es el único aminoácido con contenido de azufre, por ello la metionina juega un papel importante en la síntesis de muchas proteínas importantes, como la carnitina o la melatonina, igualmente interviene en la disoluciónde grasa y limita la acumulación de grasa en el hígado.

La metionina es una sustancia importante para la formación del cartílago

Para su formación el cartilago de las articulaciones necesita azufre. En el caso de que en el organismo tengamos poca disponibilidad de azufre, no existe ningún problema a largo plazo para las personas sanas, pero en las personas que sufren de artrosis, una deficiencia de azufre, sin embargo, puede tener un efecto negativo en el comienzo de la enfermedad, especialmente en el proceso de curación del tejido dañado.

En investigaciones recientes se ha demostrado que el cartílago de las personas sanas posee aproximadamente tres veces más azufre que el cartílago de los pacientes con artrosis. Otro problema es que muchos fármacos forman sulfato, es decir, las sales del ácido sulfúrico. Esta es también la razón por la que la demanda de azufre para los pacientes con artritis es particularmente alta.


MetioninaSe recomienda impulsar la producción de azufre en el organismo. Ahora bien, no se puede tomar «azufre» tan fácilmente en forma de suplemento nutricional; por ello lo aconsejable es tomar el aminoácido metionina, que especialmente en combinación con las vitaminas B, puede formar casi todos los compuestos que contienen azufre. Y por ello la metionina es de especial importancia para los siguientes tres casos: reduce la inflamación, es calmante y estimula la formación de las células del cartílago.

La metionina fortalece las uñas y nos ayuda contra la caída del cabello

Debido a su capacidad para formar cadenas que contienen azufre, que a su vez se conectan entre sí, la metionina es capaz de fortalecer la estructura del cabello y las uñas.En 2006, en el marco de un congreso dermatológico realizado en Florencia, se publicaron los resultados de un estudio en el que participaron pacientes con alopecia, en el mismo se pudo comprobar que la cantidad de cabellos que se encontraban en la fase de crecimiento dentro del grupo que consumía un combinado de aminoácidos y vitaminas del grupo B eran significativamente más altas que la del grupo control (placebo).

Methionine Applied in Animal Production

Methionine is essential amino acids in animal, it plays an import role in poultry growth. Now, we are talking about Methionine Applied in Animal Production.

1. Application of laying hens

Methionine have a good preventive effect on heat stress on laying hens . In summer put zinc methionine into hens diets supplemented with 200mg / kg, test confirmed that 200mg / kg zinc methionine  can enhance immunity and anti-stress capability for chicken, promote appetite, reducing egg broken, enhancing eggshell thickness, improve egg weight, egg production, feed efficiency and economic benefits.

2. Application of swine production

Zinc methionine, as a organic zinc with high bioavailability, has also been a certain application  in pig production. Effect of zinc methionine on growth performance, the results showed that dietary supplemented of zinc methionine 300,350,400mg / kg treatment group compared with daily intake 40mg / kg group, the control group was up 21%, 22.2%, 21.2% . And diarrhea rate three experimental groups compared with the control group were significantly different. Wang Naiying (1996) reported, adding fattening dietary zinc methionine, average daily gain of 9.7%, 3.3% and feed efficiency, and its slaughter rate and lean meat were increased.

3. Application in Ruminant Production

Because zinc methionine holds chemical stability, biological titer, digestible absorption, interference, toxicity characteristics, while its rumen function, it  prevents the degradation of rumen microbial methionine, but also to avoid the metal elemental zinc toxicity on rumen microorganisms and methionine zinc chelate and after reducing the amount of ammonia decomposition, to reduce intermediate links, thereby increasing the absorption of blood and protein content of amino acids, beneficial to ruminant production performance of the play.


Zinc methionine has obviously effect in terms of biological potency, stability, performance, or promote, disease treatment and prevention aspects of animal production than other forms of zinc source. In summary, adding zinc methionine for pigs, chickens, ruminant diets after, economic efficiency is very significant enhanced. We should rational use of zinc methionine based on the breeding characteristics of science in the future, it can obtain a more considerable economic benefits in animal husbandry .
