A proposal for the development of a feed consumption database using a standardised feed classification system

There is currently no comprehensive feed consumption database using a harmonised feed classification system. This means there is a lack of accurate information on the individual amount of feed consumed daily by farmed and companion animals. Such a database would support exposure assessments of feed. This report provides a complete overview of the main feed databases, their structure, and how feed materials are classified. It highlights their limits and potential and reports any differences from FoodEx2. A proposal for future updates of FoodEx2 and the development of a comprehensive feed consumption model database is provided. The proposed model database is based on three information areas represented by three Excel sheets. These represent Animal, Feed, and Consumption, allowing the determination of animal dietary exposure. A proof of concept of the developed model database was carried out by performing two case studies focused on genetically modified feed and feed contaminants. For genetically modified feed, a reduced animal dietary exposure was obtained compared to estimations reported in the scientific opinions and obtained using Excel calculators proposed by EFSA. For the contaminants in feed, differences were limited, resulting in slightly higher or lower exposure values. Weaknesses and possible mitigations are also addressed, and recommendations are made for a comprehensive feed consumption database. These include recommendations establishing an EU classification system in which the main features and items reported in the European Catalogue of Feed Materials are harmonised with FoodEx2. It is also recommended that real-life animal consumption data are collected by the feed industry, animal nutritionists, breeders, and farmers, along with the collaboration of stakeholders.
