Practice

Benefits

To meet the lysine requirement with diets that have or have not met the crude protein requirements

Making up for the lysine deficiency of feed ingredients

Saving the cost on expensive feedstuffs of protein sources

Reducing the energy need for deaminating excess AAs

Maintaining or improving animal performance

Maintaining or even increasing the production profits

To further decrease the dietary concentration of crude protein

Decreasing manure N concentration and in turn the N excretion to environment

Further saving the cost on expensive feedstuffs of protein sources

Reducing the energy losses associated with excess urinary N and heat increment

Decreasing the NH3 emission into the air

Reducing the odor in the production facilities

Using inexpensive feedstuffs of alternative protein sources

Decreasing animal water consumption

Decreasing the volume of animal waste such as manure
