In the world of poultry nutritionists, probiotics have a very high
regard. A recent survey by WATT
Global Media revealed that when it
comes to replacing antibiotics, probiotics are always in the mix of additives. Sometimes, they are used even
in the presence of antibiotics, assuming antibiotics do not kill them. To
this end, it pays to ensure that the
specific strain of probiotic used to replace antibiotics is not killed or suppressed by other antibiotic-replacing
additives. Such could be the case of
acid-sensitive probiotic strains.

may interfere with the immune
system, whereas others stimulate
the digestive system. In most cases,
modern products are protected, as
some of their comprising elements
can be very volatile.

4. NSP enzymes
Broilers and non-starch polysaccharides (in this case we refer only
to beta-glucans and arabinoxylans)
are not an ideal combination. The
viscosity conferred by high NSP
levels tends to slow down digesta
passage while at the same time prevents enzymes from entering into the

3. Phytogenics or
phytobiotics
These are the same products
we used to call "essential oils," but
because this group now contains
every possible compound that can
be found in plants, we changed to
a more generic term. They are not
used as widely as organic acids and
probiotics, at least in the EU, but they
are making a very strong entrance
in the U.S. market. All together they
are viewed, correctly or not, as
supplementary to organic acids, if
only because clever marketing placed
them as potentiating the action of
organic acids. This might be true, but
is not always the case. For example,
some phytobiotic compounds

digesta, which results in reduced feed
intake and nutrient digestibility. This
would have nothing to do with antibiotic replacement if certain pathogenic
bacteria did not find a safe harbor
in the viscous digesta to proliferate
or survive the antibiotic action of
feed elements. This was resolved by
the strong action of antibiotics, but
replacements are not as potent and,
as such, breaking down the viscous,
gel-like material is considered one
step toward effective replacement of
in-feed growth-promoting bacteria.

5. Insoluble fibers
Although the NSP compounds
mentioned above are part of the "fiber" component of feeds, this group
