During the 2025 European Symposium on Poultry Nutrition (ESPN), set to take place from 23-26 June in the Netherlands, Trouw Nutrition will be hosting two oral presentations and nine scientific posters, with research spanning poultry production systems.
Trouw Nutrition will unveil poultry nutrition research findings during the European Symposium on Poultry Nutrition (ESPN), in Maastricht, the Netherlands, from 23-26 June, 2025. During the biennial scientific gathering organised by the Netherlands and Belgium chapters of the World Poultry Science Association, the company will host two oral presentations and nine scientific posters, with research spanning broiler and layer production systems. The company explains that the research it will be sharing at ESPN 2025 includes the following posters, presentations, and programmes.
BROILER RESEARCH INSIGHTS FROM NUTRECO’S GARDEN OF THE FUTURE
Ongoing research at the Nutreco Garden of the Future in Switzerland is expanding the development of novel phytoComplex solutions as dietary tools to improve poultry health and performance, along with producers’ businesses. Findings from several broiler studies and layer programmes involving research conducted on product development from the Nutreco Garden of the Future will be shared at ESPN. The company points out that:
- Two products were tested as potential immune support for broilers given a Salmonella typhimurium vaccine. Results for broilers receiving the PhytoComplex (Fytera Care) or phytogenic (a competitor) supplements suggested that adding specific natural plant extracts at precise levels could make Salmonella vaccines more effective without harming bird performance.
- A series of studies explored the influence of a novel blend of phytoComplex materials mixed with target-release butyrates for high-performing broilers. Analysing data from all trials found that including the feed additive improved body weight gain and tended to improve feed efficiency in high-performing broilers compared to control results.
- Research also looked at the early translocation of enterococcus cecorum from the bird’s gastrointestinal tract into other organs. Enterococcus cecorum is the leading cause of kinky back disease, which impairs broiler mobility and growth performance. Research findings showed that E. cecorum translocates very early in broilers, which can be influenced by nutritional strategies, including the use of phytoComplex blends for early intervention and disease management.
EXTENDING LAYER LONGEVITY AND PRODUCTION
Recent advances in genetics offer the potential for layers to reach 100 weeks of production and generate 500 eggs, Trouw Nutrition points out. The Layer Longevity Programme (LLP) is designed to boost laying hens’ longevity and productivity. Currently available in Europe and launching soon on other continents, the LLP uses precision nutrition in combination with harmonising solutions to help producers meet their flocks’ needs and unlock birds’ genetic longevity potential.
An oral presentation at ESPN will unveil findings from an LLP study that highlight a significant correlation between body composition (including fat, ash, and protein content) at the onset of lay and hen performance up to 100 weeks of age. These findings were assessed using an internal prediction model developed by Trouw Nutrition’s R&D department, using a noninvasive bioelectrical impedance tool. Furthermore, Trouw Nutrition will present a scientific poster detailing two studies supporting the LLP at ESPN. The company shares a preview of each study below.
A NON-INVASIVE METHOD FOR ASSESSING LIVER HEALTH AND PREDICTING LIVER PARAMETERS
While liver health is an important indicator of layer hen productivity and longevity, traditional methods to assess liver health are invasive. At ESPN, Trouw Nutrition will share how bioelectrical impedance analysis offers a non-invasive means of measuring the electrical traits of tissues and estimating liver weight and fat content. Combined with nutritional data, BIA has shown potential to predict key liver parameters that may ultimately contribute to extended production cycles. Such insights can support nutritionists in optimising diets for certain physiological traits that are beneficial for egg production.
BALANCING FAST PROTEINS (FP) AND RESISTANT FIBER (RF) IN LAYER DIETS
Trouw Nutrition will present data showing the relationship between fast proteins and resistant fiber. By balancing these two components of feed, poultry nutritionists and farmers can improve their feed conversion rates and support their bottom line.
Remarking on Trouw Nutrition’s presence at ESPN, Araceli Olivares, Global Poultry Portfolio Manager, stated, “Technological capabilities, botanical science, and advanced genetics are accelerating the pace of innovation in the poultry sector. As a gold sponsor of ESPN, Trouw Nutrition is proud to collaborate with poultry professionals around the globe in advancing understanding of how nutrition can contribute to efficient and profitable poultry production.”
