Kindly Tips for amino acids in animal feed

Adding amino acids in animal feed meets the demand for animal protein, improving feed utilization. It may also reduce stress in animals. As a animal feed additive, it plays a significant effect for Amino acids, because of its  high price, it should be a reasonable choice, not to affect the quality of feed, reducing in economic losses.

1.It should be careful observe, identify and judge the packaging, appearance, odor, color, etc during the selection of such additives,  no use the product with doubting.

2. Amino acids are usually used in livestock feed additive, especially in the developmental stages of young animals, and sheep and other ruminants can use amino acids since the microbial synthesis,  there is no distinguish between amino acids and non-limiting limiting , generally do not use amino acid feed additive.  It is still controversial for Aquatic animal utilization of chemical synthesis of amino acids , therefore, It is better to carefull use aquatic feed.

3. During the use of amino acids in the feed, it should first consider the first limiting amino acid, and then turn to consider other limiting amino acids. Because there is a feature for animals use of amino acids that only the first limiting amino acids are satisfied, the second and the other limiting amino acids can get a better use. The first limiting amino acid lysine in pigs, the second limiting amino acid methionine; and the first limiting amino acid methionine chickens and other poultry, the second limiting amino acid lysine.

4. the amount of amino acids should be based on the content and its effective potency to convert.

Identify methionine by sensory

Identify  methionine by sensory:

1. True Methionine occurs white or light yellow crystalline powder with reflective, but false methionine occurs yellow or gray, little crystalline;
2. True methionine occurs special smell, false methionine smells not pure;
3. True methionine tastes slightly sweet, non-astringent sense; Adulteration of non-sweet smell while having impurities feeling;
4. pure methionine touch creamy texture, fake feel more rough;
5. hydroxysteroid methionine is a brown powder or granular, with hydroxyl group special smell.
6. aluminum products or plastic spoon inserted into methionine feed, a few turns out, there is static,  but fake not.
7. A small sample was added into 100ML water, stirred five seconds and stand, true methionine can be completely dissolved, if not, fake methionine.

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).

Tips for Animal Feeding by DL Methionine Feed Grade

                        

                               Tips for Animal Feeding by DL Methionine Feed Grade

During raising animals, farmers take care animal baby carefully, not only animal accommodation, daily diet, loss of appetite. So as a feed additive, synthetic amino acids can improve the quality of livestock and poultry, lysine added into broiler diets can improve meat quality. So,what are tips can be noticed in fed animals by feed grade methionine?

Common sense for feed grade methionine: Broiler adds 0.1 to 2.5%,hens adds 0.1 to 0.2%, egg preliminary 0.1% from 0.05% late egg, it is preferable to add 3 to 5% into chicken feed with beef tallow, lard, Soybean oil (7300,46.00,0.63%) and other fats. In pigs feed, methionine takes 50%  percentage of lysine, but, in broiler hens feed, it is necessary to add sufficient methionine. If soy meal (4552,2.00,0.04%) substituted by rapeseed cake(5160,46.00,0.90%), cotton seed cake , the amount of lysine will be increased by 20%; If soybean meal (3645, 18.00,0.50%) is substituted by fishmeal , the amount of lysine can be reduced by 20%.  During design formula for pigs feed, it is import to consider the breed of pig, different stages and  varieties of feed raw materials, in order to obtain a better feed efficiency.

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 .

Low-protein amino acid–supplemented diets for growing pigs: Effect on expression of amino acid transporters, serum concentration, performance, and carcass composition

Pigs fed protein-bound AA appear to have a higher abundance of AA transporters for their absorption in the jejunum compared with the duodenum. However, there is limited data about the effect of dietary free AA, readily available in the duodenum, on the duodenal abundance of AA transporters and its impact on pig performance. Forty-eight pigs (24.3 kg initial BW) distributed in 4 treatments were used to evaluate the effect of the CP level and form (free vs. protein bound) in which AA are added to diets on the expression of AA transporters in the 3 small intestine segments, serum concentration of AA, and performance. Dietary treatments based on wheat and soybean meal (SBM) were 1) low-CP (14%) diet supplemented with l-Lys, l-Thr, dl-Met, l-Leu, l-Ile, l-Val, l-His, l-Trp, and l-Phe (LPAA); 2) as in the LPAA but with added l-Gly as a N source (LPAA+N); 3) intermediate CP content (16%) supplemented with l-Lys HCl, l-Thr, and dl-Met (MPAA); and 4) high-CP (22%) diet (HP) without free AA. At the end of the experiment, 8 pigs from LPAA and HP were sacrificed to collect intestinal mucosa and blood samples and to dissect the carcasses. There were no differences in ADG, ADFI, G:F, and weights of carcass components and some visceral organs between treatments. Weights of the large intestine and kidney were higher in HP pigs (P < 0.01). Expression of b0,+ in the duodenum was higher in pigs fed the LPAA compared with the HP diet (P = 0.036) but there was no difference in the jejunum and ileum. In the ileum, y+ L expression tended to be higher in pigs fed the LPAA diet (P = 0.098). Expression of b0,+ in LPAA pigs did not differ between the duodenum and the jejunum, but in HP pigs, the expression of all AA transporters was higher in the jejunum than in the duodenum or ileum (P < 0.05). The serum concentration of Arg, His, Ile, Leu, Phe, and Val was higher but serum Lys and Met were lower in pigs fed the HP diet (P < 0.05). These results indicate that LPAA can substitute up to 8 percentage units of protein in HP wheat–SBM diets without affecting pig performance; nonessential N does not seem to be limiting in very low-protein wheat–SBM diets for growing pigs. Also, the inclusion of free AA in the diet appears to affect their serum concentration and the expression of the AA transporter b0,+ in the duodenum of pigs.

DL-Метионин

DL-метионин кормовой, применяемый в порошкообразной форме, почти в три раза эффективнее усваивается организмом, чем такой же препарат в жидком виде. Нехватка веществ, содержащихся в DL - метионине, приводит к снижению аппетита, атрофии мускулов, анемии, ожирению печени. В результате, резко падает показатель продуктивности и набор веса. Яичный белок вырабатывается с замедлением, соответственно, снижается продуктивность. Кроме того, если в корме наблюдается нехватка витамина Е, птица заболевает дерматитом и дистрофией мышц. Препарат хорошо смешивается с кормами, поэтому его использование достаточно эффективно. Метионин безопасен для оборудования – он не вызывает порчи металлических частей оборудования в кормоцехах.

DL-метионин кормовой используется для обогащения полезными добавками комбикормов, премиксов, смесей при составлении рационов для животных. Дозируется препарат применительно возраста, вида, условий содержания.

How to Distinguish Methionine True or Not ?

                    How to Distinguish Methionine True or Not ?

DL Methionine is an essential amino acids that plays an important role in feed field. However, there is lots of fakes in methionine market. So, I would like to share some tips for your reference:

1.  Burn, do not leave residue, there is an smell of burnt feathers;

2.  Touch, there is a special smell methionine (hydroxysteroid special smell hydroxyl group) with true methionine;  a little sweet when taste, touched smothly not rough .

False methionine smell bad, such as ammonia or Aroma smell , feel rough, not creamy.

3. Dissolve: Take methionine around 1 gram , add distilled water 50 ml, stir gently, shaking, standing, solution clearly and no precipitation with real methionine; If not, it is false.

DL Methionine Introduction

Methionine,an important amino acid species of animal feed, is an essential feed additive added into animal feed, which helps animals grow rapidly in a short time. It saves about 40% of the feed. In particular, feed poultry feed, methionine is the first limiting amino acid. Lacking of methionine for animal  will cause dysplasia, weight loss, liver and kidney function decline, muscle atrophy, deterioration. 1kg methionine  added into animal feed is  equivalent 50kg nutritional value of the meal (added in an amount of 0.05% to 0.2%).

Methionine is devided into DL- methionine, methionine hydroxy, hydroxy methionine calcium salts, N- hydroxymethyl methionine. In the feed industry, the demand for methionine is significant, particularly amino acids in nutritional feed additives, 60% of methionine, lysine 30%, about 10% of other amino acids. Methionine consumption structure, the feed additive is the largest consumer market.
