Effects and functions of feed grade amino acids

The main effects and functions of feed grade amino acids include promoting animal growth, increasing feed utilization, improving meat quality, promoting calcium absorption, resisting stress, improving disease resistance, preventing animal diarrhea, attracting fish, and acting as a flavoring agent.

Promote animal growth and improve feed utilization: Amino acids can meet the needs of animals and promote animal growth, and improving amino acid balance can improve feed utilization and save protein resources. For example, adding lysine and methionine can improve the balance of amino acids in diets, thus improving feed utilization. 
Improve meat quality: Amino acids can improve the quality of meat, for example, lysine can improve the muscle quality of broiler. 
Promote calcium absorption: certain amino acids such as methionine can promote the absorption of other nutrients in the animal's body, including calcium. 
Resist stress and improve disease resistance: adding amino acids can reduce the stress of animals, improve disease resistance, and prevent the maladaptive phenomena produced by environmental changes in animals, such as tail biting and other stress phenomena. 
Preventing animal diarrhea: in intensive feeding, by adding amino acid can reduce animal diarrhea and other digestive system diseases and improve animal's digestive function.
Attracting fish and as flavoring agent: amino acids can attract fish and be used as flavoring agent in feed.
In summary, feed grade amino acids have multiple effects in animal feeding, which can promote animal growth, improve feed utilization, improve meat quality, promote calcium absorption, resist stress, improve disease resistance, prevent diarrhea and attract fish. These effects are important for improving the productivity of animal husbandry, improving animal welfare and protecting the environment.
