7 additives to replace
antibiotics in US broiler feeds
With the United States entering the fray on antibiotic-free-raised
broilers, it is interesting to review what is working so far based on
experiences from Europe and what is marketed in the U.S.
BY IOANNIS MAVROMICHALIS

U.S. rules, something the EU has
carefully managed to avoid, so far.
All this antibiotic-free experience gained on both sides of the
Atlantic has revealed certain patterns when it comes to removing
long-standing antibiotics from
broiler diets. Of course, feed formulas should change and health
should be improved farm-wide,
but these are the inglorious works
of nutritionists and veterinarians.
Somehow, the focus remains on
feed additives that can replace

antibiotics, sometimes with little
regard for the requirements for
deeper changes. Nevertheless,
these discussions can be summarized in a brief list of alternatives
to antibiotics based on my experiences and discussions.

1. Organic acids

Alisha Winson, Dreamstime.com

It is no secret that the United
States is following the path highlighted by the European Union,
at least when it comes to banning
growth-promoting antibiotics in
broiler diets. In fact, in several
well-known instances, the U.S.
broiler industry is taking it a step
further, refusing to use antibiotics
even for therapeutic purposes in
what is known as the  Never Ever
3 (NE3) marketing program. To
make matters worse, coccidiostats
are classed as antibiotics under

There is no doubt that the big
alternative to antibiotics is organic
acids. Free, coated, straight or
salts, these compounds have been
shown to possess the strongest
antibacterial activity. Not all work
the same, as their site of action depends on gut pH and the acid's pKa
value. Also, they have different potency against the many and varied
types of bacteria in the gut. And,
of course, inclusion rate is not the
same for all organic acids. Here, it
merits repeating that adding 1 or
2 kg organic acids per metric ton
of complete feed is barely enough.
We need much more than that, but
then cost becomes prohibiting, and
this low-inclusion level often explains why testing new products is
often inconclusive.
