Research output: Book/ReportReportProfessional


The International Association for Feeding stuff Analysis, section Feeding stuff Microscopy, organises annually a ring test for animal proteins for all their members. In this report the ring test for animal proteins is presented, which was organised by RIKILT in 2011 on behalf of the IAG section Feeding stuff Microscopy. A contamination level below 0.1%, i.e. 0.05% of animal proteins from terrestrial animals is also part of this ring test. The derogation to use fish meal for weaning ruminants, and the desire for further relaxation of the extended feed ban gave rise to inclusion of a contaminated fish meal, and a feel adulterated with feather meal. The main purpose of the ring test is to monitor the performance of the participating laboratories. The main part of this report presents and discusses the results in terms of sensitivity and specificity scores.
