The importance and physiological role of arginine in broilers

"Because nitric oxide is the discovery of a signaling molecule in the cardiovascular system", the three researchers won the Nobel Prize in Physiology or Medicine in 1998.

Nitric oxide has very important biological functions, mainly derived from the conversion of arginine into citrulline and nitric oxide in the body.

In addition, polyamines, as arginine metabolites, have the function of promoting cell differentiation/proliferation.

For poultry, due to the lack of carbamoyl phosphate synthase in the body, it cannot synthesize arginine by itself.

For mammals such as humans and pigs, arginine is a conditionally essential amino acid, because the urea cycle of mammals is closely related to the synthesis of arginine.

In the evolution of animals, different species have different nitrogen excretion methods.

In addition, with the genetic improvement of broiler breeds, the arginine nutrient requirements of broilers are constantly increasing (Aviagen, 2007, 2014).

　　In addition, the research on the best arginine to lysine ratio of broiler chickens jointly carried out by CJ BIO and Spanish IRTA shows that the best arginine requirement in the feed for improved modern breeds of broiler chickens is that the ratio of arginine to lysine reaches 115.

　　Arginine plays a variety of functions in poultry.

　　First, improve reproductive performance.

　　Secondly, arginine reduces belly fat.

　　Third, alleviate high temperature/low temperature stress.

　　Fourth, it can promote bone development.

　　In addition, the arginine deficiency group (arginine/lysine=75%) had the lowest survival rate of broilers [Figure 5].

　　In broiler diets, arginine is an essential amino acid that must be obtained from external sources.
The lack of arginine affects the level of arginine and its derived metabolites.
Therefore, arginine is a factor that needs to be considered when designing a formula.
In broiler diets, the requirement of arginine varies by factors such as environment, disease and age.
The latest research results show that the optimal requirement of arginine in broiler diets is the ratio of arginine to lysine of 115%.
Due to the short growing period of white feather broilers, the supply of functional essential amino acids is indispensable.
As a universal amino acid, arginine needs to be added from now on!XDu China Feed Industry Information Network-Based on feed, serving animal husbandry
