A study with Nile tilapia conducted in commercial production cages in Brazil showed the potential – in the absence of major disease threats – of a commercial, natural growth promotor that modulates the microbiota (inhibiting growth of pathogenic bacteria and
Increased attention to nutrient digestibility and gut health are two important focus areas for technological development of manufactured feeds in the aquaculture industry. Both laboratory and field studies have demonstrated the potential benefits for aquaculture productivity and the economics of
The digestive systems of shrimp are main entry points for bacterial and viral pathogens, and unfavorable microflora. Natural feed additives that combine different actions have proven effective in improving survival where shrimp are exposed to bacterial pathogens.
The pathogenicity of early mortality syndrome in shrimp is likely regulated by quorum sensing, which allows the Vibrio bacteria that colonize shrimp guts to coordinate the release of the toxin that damages shrimp digestive systems.
Cholesterol is an essential nutrient for penaeid shrimp. Trials found that a digestibility enhancer based on natural emulsifiers was as effective as purified cholesterol in improving shrimp growth and feed conversion.
In a study with pangasius, dietary administration of a blend of botanical extracts improved performance, reducing intensity of gill parasite infestation.
Through two lab trials, the authors examined the potential of feed additives to increase growth and feed utilization in Nile tilapia.
In a study with gilthead sea bream, two test diets used primarily soy products as sources of protein and fat against a reference feed based largely on fishmeal and fish oil.
