There are two methods of least cost feed formulation.
1) Linear Formulation
Almost all commercial feed formulation software use Linear
Programming Method. Mathematically, this method provides only
50% assurance to meet nutrient level in the ration.
2) Stochastic Formulation
The other method is called Stochastic
Programming. This method can raise assurance to meet nutrient
level in the ration from 50% to 99.99%.
WinFeed is the first feed formulation software in the world that
has capability to formulate least cost diets based on Stochastic
Programming. To learn more about Stochastic Feed Formulation
