ARTICLE FEED & ADDITIVE MAGAZINE March 2024 75 In a second experiment, the NQ technology was used with a "matrix value" at 75 ppm. Three treatments were tested: 1) an initial control diet [C0], 2) a second treatment that consisted of the same control diet but with reduced energy and protein content (23kcal/kg, 0,23%CP, -0,08% Dig Lys) [NC], and finally, 3) a third treatment was given to animals based on the control diet, with reduced energy and protein content (23kcal/kg, 0,23%CP, -0,08% Dig Lys) along with the NQ technology at 75 ppm [NC+NQ]. In this case as well, the experiment consistently delivered expected results. Applying a matrix to the control diet (NC) adversely affected laying percentage, egg mass, and FCR but did not alter feed intake when compared to the control. Applying NQ technology with a matrix value (NC+NEX) helped to restore layer performance, with the laying percentage even slightly surpassing that of CO. Beyond performance indicators, additional assessments highlighted the influence of the NQ technology. Researchers observed a decrease in both fatty liver scores and occurrences. Moreover, there was an enhancement in eggshell thickness, whether the technology was used in a diet, with or without a matrix value. OPT FOR THE LATEST, SCIENCE BACKED TECHNOLOGY TO SAFEGUARD PROFITS In the evolving landscape of the egg industry, the NQ technology emerges as a revolutionary solution. By seamlessly combining exclusive ingredients sourced from both plants and algae, it offers a distinctive advantage. What sets this technology apart is its genuine micro-encapsulation method, ensuring the safe and efficient release of active components. Through extensive trials, the remarkable effects on laying hens' performance, improved feed digestibility, enhanced egg quality, and notable reduction in costs have been demonstrated. NQ technology is not just one more phytogenic feed additive, but rather the most advanced nature-based technology for optimizing laying hens' performance at competitive cost. It serves as a cornerstone for the future of egg production, delivering unparalleled advantages to producers and championing healthier, more sustainable laying hens' operations.

She obtained her MSc degree in Food Technology with a specialization in Food Ingredient and Functionality and her PhD degree in Food Chemistry from Wageningen University (The Netherlands). During her PhD thesis, she studied in depth the human gut microbiota composition and its modulation upon prebiotic supplementation and/or antibiotic treatments. From 2014 till 2020, she worked at Cargill Animal Nutrition, first as technology lead for gut health additives and, then, as swine portfolio manager. She provided global technical product support for a broad range of products (phytogenics, organic acids, short and medium chain fatty acids, probiotics) and trained technical and sales teams. She most recently managed R&D projects and developed innovative feed additive solutions to answer specific customer needs related to animal gut health and performance.
