PHYTOGENICS
decades, phytogenic feed additives
turned out to be a potent tool to modify
the physiology of livestock animals
allowing to boost their performance.
Phytogenics comprise a broad
spectrum of plant-derived substance

classes, not restricted to essential oils
only - this diversity makes research
more complex, but it represents a
huge potential for future development
of innovative phytogenic feed additives. Systematic studies on nutrient

digestibility prove that supplementing
a combination of essential oils with
saponins exceeds the beneficial effect
of those phytogenic compounds in
comparison to feeding the same
compounds separately. ■
