Four Early Stage Researchers (ESRs), Alba Tres (Wageningen University),Themis Altintzoglou (Nofima), Kathrine Livingstone (University Reading and Tamar Frankic (University of of Ljubljana) have organised a successful workshop entitled “Feed your knowledge!” on 7-8th June, in Barcelona Spain. This workshop was arranged within the COST Action Feed for Health. The four ESRs were selected by the coordinator of the Short Term Scientific Missions (STSM) from the COST Action. It was meant to be for the ESRs a learning by doing process. The ESRs team held in February in Brussels a kick off meeting and several telephone meetings followed. They arranged invited the invited speakers, composed the programme and made all practical arrangements with the local host University of Barcelona. Luciano Pinotti (University Milan), being the chair of this COST Action and Joop Luten (coordinator STSM COST Action) were supervising the organisation process. The ESRs team aimed to organize a workshop specially aimed at young scientists conducting their research in the feed for health area, and especially to those who were involved on a Short Term Scientific Mission within the COST Action Feed for Health. For two days, young and senior researchers from more than fifteen countries have met in here in Barcelona to exchange current knowledge on feed, animal, and food production. Animal nutrition and its effects on animal health and on the composition of food products are among the hot topics in Europe´s agriculture sector. Animal welfare, food safety and functional foods are among the current consumers’ concerns. Therefore, several research groups in Europe are aiming to increase knowledge of feed composition and animal nutrition, in order to assure animal welfare, and to produce animal food products that fulfil the requirements regarding safety, functionality and sustainability of our society. There were three keynote speakers that addressed a variety of topics on feed and food research: pet nutrition, animal production and human nutrition and ageing. As it is not just about conducting state-of-the-art research to develop a scientific career and to become a leading scientist, the ESRs organising team had also included a session on career prospects for young scientists. Knowing which tools the society (from governmental institutions to private companies) offers to young researchers to develop their career and how to implement their skills are key issues that sometimes do not receive enough attention. For this session they had three invited speakers who shared their knowledge of career development and provided some tips and suggestions for strategies to become a leading scientist, both in public institutions and in industry. More than 70 participants came together in the workshop to give 35 presentations. On the photo you can see the opinion of the participants about the workshop.
