Proficiency Testing Program

AAFCO supports laboratories testing feeds, feed ingredients and pet foods with four unique proficiency testing schemes that provide performance assessment for laboratory test results.  Proficiency Testing Rounds are distributed to customers on a predetermined schedule and are tested for analytes of interest by each laboratory.  Results for individual analytes are reported using specified AAFCO method codes and units to allow for statistical analysis of the performance of individual methods or method types.  Laboratory data are reported using the AAFCO Data Reporting Website.  Reported results are analyzed statistically and customers are provided with performance scores for each analyte and method reported.  Report cards and consensus reports are downloaded from the Data Reporting Website. We offer four related Programs that target different testing needs. Extra materials from each testing round are offered for purchase as Quality Reference Materials (QRMs) or “past samples”.

Monthly Animal Feed Scheme

The Monthly Animal Feed Scheme consists of monthly rounds of a commercial feed proficiency testing material. The scheme begins in January and includes a variety of feeds and supplements with nutrients, drugs, antibiotics, minerals, and vitamins at levels typically encountered in commercial products. At least once annually, a dry pet food is distributed and once annually the round comprises a feed ingredient and a mineral pre-mix supplement (two materials). This scheme is available worldwide.  The subscription cost for 2017 is $300 plus shipping.  Subscribe using the web form below:
