Phytogenics: combinations
and synergies in poultry feed
Broad utilization of phytogenics in animal feed results
in different modes of action
ELISABETH ROHRER AND ANNE OBERDORF

The potential of phytogenic feed

secretion of digestive juices and
influencing intestinal nutrient transporters, antioxidant and anti-inflammatory effects, quorum sensing
inhibition and gut wall protection.

Continuing phytogenic
research
While initially met with skepticism, phytogenic feed additives are
increasingly accepted in animal
nutrition and production. Ongoing
fundamental and applied research
to uncover the diverse modes of
action of phytogenics has been
explored through standardized trials
and independent evaluations. Such
studies have also identified why
and how phytogenic feed additives
achieve the broad spectrum
of claimed benefits.
Phytogenic feed additives represent a wide range
of classes of plant-derived

substances, each with individual
modes of action. However, the
research becomes even more
complex when trying to understand how specific mixtures of
phytogenics influence an animals'
physiology in their interaction.
Although further research
on this topic is required, there is
good evidence that the combination of different phytogenic
substances may pronounce the
effects of the single components.

Effect on broiler digestibility
A 21-day study of 144 Cobb 500
broiler chickens aimed to investigate the effect of a specific essential
oil blend and a saponin mixture on
apparent ileal nutrient and amino
acid digestibility. Researchers
randomly fed the birds four treatments and either supplemented a)
no additive, b) an essential oil blend

hytogenic feed additives
represent an important
class of natural feed additives used as natural enhancers of
livestock performance and feed
utilization.
Phytogenics consist of plantderived, bioactive substances,
including the whole repertoire of
secondary plant metabolites. They
comprise a multitude of different
substance classes, which offer a
broad spectrum of modes of action.
Essential oils, saponins, flavonoids, mucilages, tannins, pungent
substances, bitter substances
- each influences an animal's
physiology with specific modes of
action, for example, regulating the
