NEWS 20 FEED & ADDITIVE MAGAZINE March 2024 Lallemand Animal Nutrition shared new trial results conducted on L. vannamei shrimp in China, Tianjin, that confirm YANG helps support immunity, antioxidant defenses and intestinal health. The company notes that these benefits are translated into improved production performance for shrimp farmers. YANG is a specific yeast derivative specially developed by Lallemand to elicit a balanced immune response. The goal of the trial was to evaluate the effect of YANG supplementation on non-infectious immunity, such as antioxidant defenses, intestinal health, growth performance and survival of L. vannamei, and to check, at the end of the trial, the effect of the diet on a vibrio challenge, Lallemand explained. The trial was conducted on juvenile white shrimp, comparing a standard commercial feed to the same feed supplemented with increased levels of the yeast derivative YANG. On day 56, shrimp were challenged with Vibrio parahaemolyticus. “This new trial in shrimp shows the benefits of YANG on antioxidant defense mechanisms, which are part of what we can call the non-infectious immune response, as well as on gut health," says Stéphane Ralite, Aquaculture Product Manager at Lallemand Animal Nutrition. "These results are in addition to previous trials in shrimp demonstrating the positive effects of YANG on mechanisms such as phagocytosis, melanisation and respiratory burst activity — each of which are more related to what could be called the infectious immunity. Interestingly, with this balanced immune support, we can see in this experiment that, even at high doses and after a continuously long time supplementation, YANG exerts benefits on global performances and improves resistance to a pathogen challenge.” Read more>> New trial: Yeast derivative supports immunity and intestinal health In order to support the acceleration of its production and sales growth, which more than doubled in 2023, Innovafeed unveiled its new brand Hilucia™. With Hilucia™, the company redesigned its offer around a complete range of high-quality ingredients for animal and plant nutrition, with minimal environmental impact. Hilucia™ embodies the combination of the exceptional upcycling capabilities of the Hermetia illucens larvae with the cutting-edge technology developed by Innovafeed's teams, according to the company's statement. “Enhanced and expanded with two new products - protein for monogastrics and oil for aqua - the Hilucia™ range reaffirms Innovafeed's anchoring and leadership in its four main markets: pets (Hilucia™ for pets), livestock (Hilucia™ for monogastrics), aquaculture (Hilucia™ for aqua), and agriculture (Hilucia™ for plants),” said Elizaveta Le Floch, Chief Business Officer of Innovafeed. The company states that the Hilucia™ range is the result of an extensive effort made in recent years by Innovafeed's teams. Innovafeed emphasizes that it has created a unique model of "industrial symbiosis" that maximizes the natural productivity of Hermetia illucens larvae. This model is based on the clustering of facilities with suppliers of the two main inputs required for insect rearing: agricultural co-products for larval feed and energy.
