Business, science behind
phytogenics in pig feeds
What do you need to know to use this family of additives with
success in pig feeds?
BY IOANNIS MAVROMICHALIS

The increasing pressure to remove antibiotic growth
promotants from poultry diets in the U.S. has renewed
interest in a family of additives that started as an
ingredient in piglet feeds for a similar purpose. The
apparent success of this additive in poultry has made
pig nutritionists give it a second chance, especially
since new developments in the formulation of phytogenic products offer solutions to many problems that
troubled earlier products. Today, phytogenics are a

no longer the equivalent of folklore
medicinal or nutritional herbs and spices,
but are a sophisticated class of additives.

thus it merits to understand the business and science
behind them.

Phytogenics started as essential oils, if only because
most, if not all, of the active compounds were previously classified as such. This is because they were used
in aromas - hence the essential part of their name that
stems from "essence." Otherwise, animals have no absolute requirement for such compounds that would classify
them as essential nutrients. The early products were ground up powders of spices
and herbs that provided these essential
oils, whereas, at best, they were simple extracts.
The major problem that prevented these products from
bypassing the initial animal test that most feed
manufacturers and pig producers accorded
them was the tremendous unpredictability in the concentration of active
compounds. As such, additive
manufacturers moved
on to purified extracts of
known concentration and
even to synthetic compounds.
