50-55% total production costs
Functional feedsFunctional feeds are regarded as the future of the aquaculture:
- by embracing nutrition strategies to address specific stresses, environmental situations, life stage requirements and pathologies, the industry can optimize animal performance as well as operational efficiency;
- by preventive health management through feed, aquatic animals can divert more energy to tissue growth and reduce biological energy reserves needed to fight disease.
Functional feeds:Functional feeds:- provide benefits other than just nutritional, - support health and reduce the risk of disease.
Certain nutrients (e.g. PHs, SDP, nucleotides) Chemicals (e.g. levamisole) Exogenous enzymes (e.g. phytase, xylanase) Immunostimulants (e.g. β-glucan, LPS) Organic acids (e.g. formic, sorbic, butyric acids) Pigments (e.g. carotenoids) Prebiotics Probiotics Synbiotics Vegetal extracts Vitamins C & E…
