ARTICLE FEED & ADDITIVE MAGAZINE March 2024 73 A recent research program highlights that micro-encapsulation of seaweed and plant extracts can stimulate digestive functions, improve performance, and reduce feed costs, addressing current egg industry needs. The egg industry grapples with key challenges in optimizing nutrition and profitability for laying hens. One significant hurdle involves efficiently producing eggs while maintaining bird health and well-being. Sustainable practices, such as efficient waste management and reducing the environmental footprint, are essential to address growing concerns about the environmental impact of egg production. To tackle these issues and enhance the performance of laying hens, strategies have emerged. These include formulating balanced diets with alternative protein and energy sources, exploring feed additives like enzymes, microbials, phytogenics, and seaweed extracts. Enzymes, such as phytase, improve nutrient utilization, while probiotics and prebiotics support gut health, enhancing feed conversion and disease resistance. Natural phytogenics provide antioxidants, affect the microflora profile, and improve digestive functions, ultimately leading to increased egg production and improved egg quality. Seaweed bioactives (so called-phycogenics), contribute as well to better gut health of animals. These strategies address challenges in egg production and meet consumer expectations for high-quality, nutritious eggs, all while promoting sustainable and eco-friendly practices. THE LATEST BENCHMARK FOR PYTHOGENIC FEED ADDITIVES Lately, a feed additives company has introduced an innovative product, NUQO©NEX (NQ), comprising metabolites sourced from both plants and algae (referred to as phytogenic and phycogenic, originating from the Greek words 'phytos' for plant and 'phycos' for algae). These metabolites are shielded by a unique micro-encapsulation technology. The utilization of micro-encapsulation has become imperative in the realm of phytogenic feed additives to mitigate the volatility of natural compounds. While the term 'encapsulation' is increasingly generic, it is crucial to discern authentic technology that not only safeguards but also effectively releases active ingredients, setting it apart from rudimentary methods like silica absorption or light-agglomeration, which may suffice for various compounds but fall short in preserving delicate phytogenics like essential oils. It is of utmost importance to delve into the manufacturing technology underpinning each product, rather than solely relying on surface-level claims. With its notably high concentration of active components and remarkable stability, this novel soluELEVATING LAYING HEN PERFORMANCE WITH NQ TECHNOLOGY Dr. Stéphanie Ladirat R&D Director NUQO
