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 .
