Gustor Aqua is a NGP that by providing antimicrobial, trophic and
immunological properties effects to the gastrointestinal tract, warrants
reduced microbial competition as well as enlarged and healthy intestinal
absorptive surface area. In case of pathological conditions such as enteritis
due to the feeding of ingredients with high anti-nutrient content or
intestinal infection by parasites, the use of Gustor Aqua stands out as a
natural tool to enhance intestinal health and nutrient utilization by the
animal and consequently productive efficiency.

General
conclusion
In order to meet the world’s growing demand for seafood, aquaculture
production is increasing significantly. However, current aquaculture
practices in many countries are exposed to high risk of disease and reduced
performance due to the high stocking densities, declining use of antibiotics
and use of plant-based diets. In such situation aquafeed formulators
must pay special attention not only to nutritional specifications but also
to reduce the potential risk of disease. That is why supplementation with
NGPs such as probiotics or organic acid salts has aroused as a natural
alternative to develop a successful nutritional program. In this sense,
both Ecobiol Aqua and Gustor Aqua have been designed by Norel as tools
to promote gastrointestinal health and the resultant maximum nutrient
utilization, leading to cost-effective, safe and profitable production when
supplemented.
