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 solution assures a precise release in the digestive tract and offers a cost-effective dosage unlike any other currently available. This technology has been meticulously developed to optimize poultry performance and can serve as an alternative growth promoter or a means to enhance feed conversion ratios and overall performance, ultimately resulting in an improved return on investment for poultry operations.
Numerous trials have validated the effectiveness of this technology in enhancing the performance of laying hens across diverse contexts and geographic regions. Concurrently, scientists have conducted assessments to gauge the technology’s precise influence on feed digestibility. This research aims to provide formulators and nutritionists with greater flexibility in their decision-making processes.
ENHANCING FEED DIGESTIBILITY IN POULTRY
In a recent study conducted at the University of Berlin in Germany, researchers undertook a comparative analysis of four treatments: a negative control, two commercial products incorporating phytogenics (referred to as P1 & P2), and a novel technology, NUQO©NEX (NQ). The findings revealed that the NQ treatment not only enhanced the digestibility of nutrients like crude fat, crude protein, and starch but also contributed to increased mineral digestibility, including crude ash, calcium, and phosphorus, when compared to the negative control. The other two solutions also improved the digestibility of certain nutrients and minerals but to a lesser extent than NQ. Notably, the NQ treatment exhibited the most pronounced effects on nutrient and mineral digestibility, resulting in the highest overall performance improvement. In sum, the NQ treatment demonstrated enhanced feed digestibility, ultimately leading to improved performance, in contrast to conventional products relying on phytogenics. This underlines the significance of the formulation’s composition (comprising both phytogenics and phycogenics) and the influence of manufacturing technology (micro-encapsulation) on product stability and release within the digestive system.
CONCRETE IMPACT ON FEED COSTS WITH A CONSERVATIVE MATRIX VALUE
The NQ technology underwent extensive testing in various global regions, including Asia, Europe, and Latin America, to evaluate its impact on the performance of laying hens. Additionally, to offer maximum flexibility to nutritionists and formulators, diverse scenarios were examined, involving the application of feed additives either “on top” of the formulation or using a “matrix value” approach, allowing adjustments to the feed formulation to reduce costs by decreasing energy and protein content. Two recent trials were conducted at Kasetsart University in Thailand under the guidance of Professor Yuwares.
In the first experiment, the NQ technology was applied “on top” at a rate of 75 ppm. Two treatments were administered to the animals: 1) a standard control diet [NC] and 2) the same diet with the addition of NQ technology on top [NQ]. This experiment yielded consistent and noticeable outcomes: Laying percentage increased by 1%, while feed intake and egg mass remained stable. Notably, the feed conversion ratio (FCR) improved by 1 point, resulting in a noteworthy return on investment (ROI) of 3.5:1 for the producer.
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.
