Research project Optimization of energy requirements for poultry

General introduction

The EWAKUIK project is investigating whether the current energy requirements standards for poultry, which date back to the 1980s, still meet the needs of the modern poultry sector. These standards determine how much energy must be present in feed to keep laying hens and broilers healthy and productive. By updating the standards based on new scientific insights, the project aims not only to optimize production, but also to limit the environmental impact, particularly nitrogen and ammonia emissions.

Research approach

EWAKUIK combines literature research, meta-analyses, and experimental work to revise energy requirement standards. For broilers, new knowledge is being gathered via indirect calorimetry in the respiration chambers at KU Leuven. In ILVO's test houses, dose-response tests are carried out to measure the effects of adjusted standards on feed intake, nutrient utilization, and performance. In addition, the relationship between the energy-protein ratio, protein intake, and ammonia emissions is being investigated. The results will result in a user-friendly tool that companies can use to accurately determine their energy requirements.

Relevance/Valorization

With validated and up-to-date energy requirement standards, the poultry sector can improve production efficiency and reduce environmental impact. Better coordination of energy and protein levels promotes optimal protein utilization and limits nitrogen losses. This provides economic benefits for businesses while contributing to more sustainable, environmentally friendly poultry production.
