14.03.2013 For the benefit of the fish Functional food by sera sera vipan, sera san, sera flora and sera GVG-mix are from now on available with so-called mannan oligosaccharides (MOS). Photo: sera Aquarists know that even a low number of pathogens may cause serious diseases if the immune system is weakened. Prevention and a strong immune system are therefore essential. sera now has launched functional food products for this purpose. They contain mannan oligosaccharides (MOS), which improve the general health condition of the fish. Nutrition, intestinal flora or stress are factors that lastingly influence the immune status of the animals. For instance, high fish density may especially in aquariums lead to stress and, accordingly, to a weakened immune system and to diseases. The problem: Effective , suitable and legal treatments are not always available. Fish enthusiasts thus are safer when preventing diseases. The new functional foods by sera are exactly the right choice in this case. sera vipan, sera san, sera flora and sera GVG-mix are from now on available with so-called mannan oligosaccharides (MOS). MOS are prebiotically effective cell wall components of a specific yeast strain that enhance intestinal health in a natural way and optimize the general health conditions of the animals fed. Numerous scientific studies as well as practical application prove the manifold mechanisms of MOS: Being prebiotics, they - among others - reduce the growth of disease causing bacteria, contribute to immunity development (under stress), improve food and nutrient utilization and blood health. They furthermore enhance growth and weight increase, and reduce mortality. In a nutshell: Using MOS in the sera foods increases well-being and lifetime of the fish being kept. The functional foods are a deciding measure for maintaining animal health. The fish become ill less frequently, infections take place more mildly, and the recovery phase becomes shorter. The functional foods by the sera innovators allow aquarists to rely on sophisticated product solutions that support the immune health of the animals.
