ARTICLE 62 FEED & ADDITIVE MAGAZINE July 2023 About Wouter de Bruin Wouter started his professional career with a leading Dutch feed producer in the pig industry. After several years of specialization in sows and piglets, he started with Phileo by Lesaffre in 2014. His main focus was to develop sales of Phileo products towards the feed industry and help implement solutions in the field with a strong focus on pigs. In 2018 Wouter took the position as Swine Technical Support for Benelux, Germany and Scandinavia. In this role, he focussed on on-farm problem solving and implementation of Phileo solutions in collaboration with the feed industry and vets. Currently, Wouter is responsible for the technical support to the sales team in Western Europe as W-EU Manager Swine. In close collaboration with Phileo R&D and local tech & sales teams he is formulating and implementing Phileo strategies based on market challenges and customer needs. The yeast group exceeded the average daily gain (ADG) in the creep and weaner stage (Figure 1). The average daily gain during the whole period was also higher in the piglet that received the yeast supplementation. The yeast group had a higher average daily feed intake (ADFI) during the creep and link stage, but not in the weaner stage. Yet, the zinc group showed a higher ADFI over the whole duration of the trial. CONCLUSION While there is no single bullet to replace ZnO and it does require a rethink and re-evaluation of piglet feeding and management practice. A more holistic approach is required that includes a healthy microbiome, limiting pathogen pressure, ensuring feed intake and more. The great news is that all these components can be improved with the application of the yeast-based feed additives that are presented in this article. The two recent trials discussed show that research continues to fine-tune nutritional tools to reduce the dependency on ZnO and antibiotics. New legislation in the pig industry might be challenging, but also spurs bright ideas in animal nutrition and powerful application in practice. Figure 1. ADG (g/d) was better in the yeast supplemented group
