The right software for the
right feed formulation job
Good feed formulation software can help nutritionists
perform to the best of their abilities.
Formulas for ruminants are a bit more complex
because they require the ration to be split into two parts
(roughage and concentrates), but the principles remain
the same. There are books, leaflets, and even online
sources that show how a simple formula is constructed.

Least-cost formulation

When we have more than one option, say for cereals,
then we need to make a decision regarding which one
