Abstract:

Methionine is an essential amino acid for livestock and poultry,and has extensive and important biological functions in the body. Recent studies have shown that methionine restriction(MetR)in the diet can lead to many physiological reactions,such as prolonging life span,preventing metabolic diseases and participating in the regulation of inflammatory diseases. As an important indicator for evaluating the health of the body,oxidative stress has received more and more attention. Many studies have confirmed the positive effects of MetR on oxidative stress. MetR can participate in the regulation of oxidative stress by reducing the production of mitochondrial reactive oxygen,regulating key signaling pathways and changing expressions of miRNAs,which has a wide range of effects on the health of livestock and poultry. This paper summarizes the effect of MetR on oxidative stress in livestock and poultry,and expounds the discovered molecular mechanism of MetR and oxidative stress.

Key words: methionine restriction, oxidative stress, mitochondrial reactive oxygen species, Nrf2
