ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE May 2024 to their diet groups and statistical analysis was performed similarly to the previous meta-analysis. To conclude this meta-analysis, no performance parameters were significantly negatively impacted by the reduction of energy when supplementing Excential Energy Plus. On top of that, diet costs were reduced, in average, by 5.26 USD/ton of feed including the cost of feeding the nutritional emulsifier. When taking into account the average feed intake and costs of the diets, a return on investment of 3.44 can be concluded. SUPPORT OF THE BROILER’S INDUSTRY PRODUCTIVITY WHILE OPTIMIZING FEED COSTS Nutritional emulsifiers are feed additives that allow for better digestion and absorption of the different nutrients in animal feed. By their key action in the fat and energy metabolism, they optimise the energy utilization of feed that can be used for growth performance. Excential Energy Plus has a well-proven record based on both scientific and commercial trials, to significantly improve growth, feed efficiency and production efficiency, resulting in higher profits. Moreover, a large variety of emulsifiers exist, from technical to nutritional ones, but they can easily be classified by describing their active ingredients and HLB values. Excential Energy Plus, a nutritional emulsifier with a high HLB value, has been demonstrated to increase the performance to a higher extent than other types of commercially available emulsifiers. Applying 350 ppm of Excential Energy Plus, ontop of a basal broiler diet without emulsifiers is expected to improve growth performance by 3.8%, feed efficiency by 3.9% and production efficiency by 6.1%. When applying the product and comparing results with another commercially available emulsifier, growth performance is expected to improve by 1.7%, feed efficiency by 2.8% and production efficiency by 2.5%. Moreover, when applying Excential Energy Plus in energy-reduced diets, it enables to maintain optimal broiler performance while reducing feed costs by 5.26 USD/ton, and resulting in a return on investment of 3.44.
