6 ALTERNATIVE PROTEIN SOURCES

DDGS are used along with corn and
not with other cereals. Nevertheless,
DDGS remain a very useful ingredient that, when used correctly, can
bring about great cost savings. 
When considering using one or
more alternatives to soybean meal,
a qualified nutritionist will take the
following four aspects into consideration before deciding about the
maximum inclusion level permissible for each diet in question: 

1. Chemical analysis.
The nutrients to be examined
are not always the same, and some
may require further qualification.
Nevertheless, the two most important nutrients are protein and fiber.
We must always strive to provide a
detailed description of how the product is produced. Here's an example:
What we might consider as a typical

cottonseed meal product (very common) may end up being a cottonseed
cake meal product (very uncommon
these days). Very similar names,
but behind them are two different
processing methods with two different byproducts as the end result. 

tion with this ingredient may result
in hens laying eggs with a greenish
yolk; a very interesting phenomenon from an academic point of
view, but a very unpleasant one for a
commercial egg farm. 

2. Anti-nutritional factors.

3. Reformulation of
existing diets.

Soybeans are a major offender
when it comes to anti-nutritional
factors. But we have learned to live
with them, even neutralize most of
them, and compensate for the rest.
So, we consider soybean meal as the
golden standard. When it comes to
novel or alternative protein sources,
however, we have a different array
of anti-nutritional factors or very
different levels of the same factors
that we largely ignore in soybean
meal. Using cottonseeds, again as
an example, inappropriate formula-

Most nutrition books will mention that such and such ingredient
may be added at x or y percent in
a given diet. This is of course an
average figure that is intended as a
general guideline for nutritionists.
For example, cottonseed meal can be
added up to 10 percent in a late-phase
diet. Is it still the same if the same
formula contains also rapeseed meal?
Or should we lower this maximum
level because rapeseed meal is also
rich in anti-nutritional factors? This is
why a nutritionist needs to reformuwww.WATTAgNet.com ❙ February 2018
