Usage
|
It is an amino acid drug and nutritional supplement. It is used for cirrhosis of the liver and fatty liver. In addition, it is widely used as a feed additive to improve feed quality, enhance the utilization rate of natural protein, and promote animal growth. For example, DL-methionine can increase the egg production of chickens, promote weight gain in pigs, and boost milk production in dairy cows, etc.
