In recent years there has been significant growth in aquaculture, and intensive production practices have inevitably caused stress in animals due to confinement, transport and handling, making them more prone to disease. At the same time, the search for alternatives to the use of antibiotics in animal production has intensified, highlighting the search for alternative solutions to control pathogens. Another focus is vaccination, which plays a key role in controlling health challenges. Its effectiveness varies according to the pathogen, the type of vaccine, the time needed to develop an effective immune response and the duration of antibodies in the blood. Therefore, it is essential to find new ways to reinforce the natural defenses of fish. A very effective alternative is the use of beta-glucans, compounds known to modify biological responses and reinforce natural defenses when recognized by specific cell receptors. At the event, Biorigin will present MacroGard, the most researched yeast beta-glucan on the market. MacroGard is highly bioactive because it is a source of extremely purified beta-1,3/1,6 glucans extracted from the yeast Saccharomyces cerevisiae. The extraction process preserves the structure of the ß-glucan molecule, thus ensuring its high bioactivity. Moreover, MacroGard contains at least 60% of ß-glucans. João Fernando Koch, Technical and Product Manager, highlights that the relevance of MacroGard in intensive fish production systems is supported by around 100 scientific articles published in renowned journals. “The product demonstrates efficacy in increasing survival against pathogens and stressors, such as temperature changes and management practices. It also highlights its efficacy in improving vaccine responses, wound healing and energy metabolism, especially in diets with high carbohydrate inclusions,” he says. During AQUASUR 2024, Biorigin will also promote its products Biotide Extra, HiCell and ActiveMOS, solutions that contribute to the development of animals in the early stages, source of highly digestible proteins, carbohydrates and nucleotides that act preserving intestinal integrity, favoring nutrient absorption and productive performance.
