Phytogenic feed additives to counteract mycotoxin impact on fish health Fernando J. Sutili, ELOAQUA Consulting
Phytogenic feed additives Phytogenic feed additives (PFAs), also known as phytobiotics or botanicals, are plant-derived natural bioactive compounds which may be incorporated into animal feeds for purposes of improving health and welfare. Being derived from herbs, spices and other plants, PFAs are commercialized as extracts, essential oils, dried powder and isolated compounds as well as mixtures of these forms. In fish production, PFAs may be used as food flavorings, antimicrobials, immunomodulators, antioxidants, digestive stimulants and technological additives to enhance feed quality and safety. One major advantage of PFAs lies in the fact that they are generally safe and do not trigger the side effects often associated
with synthetic chemical utilization. In addition, they are cost-effective and environmentally friendly. Such properties and advantages make PFAs excellent growth promoters to be used in farmed fish.
Antifungal properties Even though bacteria and viruses are considered more important animal pathogens than fungi, these have a major relevance regarding pathogens on plants. In agricultural production, plant-pathogenic fungi are the major cause of yield losses. Throughout evolution, plants have developed a wide variety of defense mechanisms to protect against fungal attack. In nature, plants synthesize a vast array of phytochemicals which play a role in protection strategies. By exerting
