Populating the ingredient
database with nutrient values
Feed formulation software requires a database of ingredients,
each with a host of nutrient values, in order to calculate the final
mix of ingredients according to our specifications.
applies to nutrients, especially if we formulate for
many species, each requiring their own nutrient
definitions.
Some software packages limit the size of their
databases first to make their programs run faster,
and secondly to keep costs down. With modern
computing power and software coding advances,
such limitations appear more as a marketing effort
to create price differentiation among one's own
products rather than as an actual effort to keep
things simple and focused to customer needs.
In populating a feed formulation system's database with feed ingredients, there are two problems
that are closely associated.

Nutrient definitions
First, we must decide what nutrient definitions
we require on which to formulate our feeds. Total
lysine was used above as an example, but scientific
advances have enabled the use of digestible lysine
instead - something that closes the gap between
the needs of the target animal and the nutritive
value of the formulated feed.

A

fter selecting the feed formulation software that we are comfortable working
with, the next step is to "populate" it with
feed ingredients. After all, all animal feeds start as
a mix of individual feed ingredients.
Nevertheless, feed ingredient names are not
alone sufficient because feeds must be made to
meet specific dietary nutrient specifications.
For example, a complete broiler feed
may be required to contain 1.5%
total lysine, and this lysine will be
provided by corn, soybean and feedgrade lysine, such as L-Lysine HCl. Thus,
these three ingredients must be entered into
the database along with their total lysine concentration. As it will be quickly realized, we will need
about 25 ingredients and another 25 nutrients for
each ingredient to be entered into the database to
start making some basic feed formulas.
As our experience and needs or opportunities
increase, more ingredients will need to be entered
into the database, creating the need to allow for a
large capacity during software selection. The same
