Certain phytogenic feed additives can support high feed efficiency in ABF (antibiotic-free) feeding strategies due to their high antioxidative power. Recent studies indicate a positive relationship between increased anti-oxidative capacity in broilers induced by certain plant extracts in feed and improved feed efficiency.

Agile power of plants
Through a multitude of bioactive substances, with a variety of adaptive properties plants are very well equipped to be polyvalent to different stressors and to prevent their negative impact. Bioactive substances derived from plants have also shown to support humans and animals to adapt to stressors more adequately and help counteract some of the negative physiological and metabolic side effects. Applying the right combination of plant extracts to feed can therefore help the animal become more robust and reach performance potential more efficiently in the face of stressors, including mycotoxins.
Oxidative stress – a common stress reaction
A common reaction to stressors is an increase in Reactive Oxygen Species (ROS) on the cellular level. ROS are produced endogenously by normal metabolic processes, but amounts may be increased markedly by certain stressors, including heat and toxins. Deficiencies of natural protective substances or excess exposure to stimulators of ROS production may result in oxidative stress, which occurs when ROS exceed the capacity of antioxidants. Oxidative stress is a major factor related to the development of inflammatory diseases.
Antioxidative power in herbs and spices
The ROS detoxification process in plants is essential for the protection of plant cells against the toxic effect of ROS. Hence many herbs and spices are rich in antioxidative defense mechanisms. The ROS detoxification systems in plants include enzymatic and non-enzymatic antioxidants. Non-enzymatic antioxidants involved include phenolic compounds, flavonoids, alkaloids, tocopherol and carotenoids. These antioxidant defense systems work in concert to control the cascades of uncontrolled oxidation and protect plant cells from oxidative damage.
Phytogenic feed additives based on extracts and material from herbs and spices with high antioxidative power, can be used to support the antioxidative capacity in animals and make them more resistant to stress factors which would otherwise increase oxidative stress and reduce feed efficiency.
