Animal Feed Scheme
The 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). Subscription to this scheme is available worldwide. The 2026 subscription cost is $540 + shipping.
Pet Food Ingredient Scheme
The Pet Food Scheme consists of quarterly rounds of a pet food ingredient and includes ingredients derived from animal or plant sources. The scheme also distributes a fifth round of dry pet food coinciding with the Animal Feed Scheme. Customers subscribed to both the Animal Feed Scheme and the Pet Food Scheme will be distributed a single unit in the dry pet food round (reflected in the dual subscription discount). Subscription to the Pet Food Scheme is available worldwide. The 2026 subscription cost is $540 + shipping.
Mycotoxin Contaminants Scheme
The Mycotoxin Contaminants Scheme consists of quarterly rounds of animal feed or pet food that has been contaminated with naturally incurred mycotoxins, including aflatoxins, fumonisins, deoxynivalenol, zearalenone, ochratoxin A and T-2 toxin. Subscription to the Mycotoxin Contaminants Scheme is available worldwide. The 2026 subscription cost is $800 plus shipping.
Minerals Scheme
The Minerals Scheme consists of quarterly rounds of animal feed, pet food, and food materials with both naturally occurring and spiked minerals at concentrations of health/toxicological significance. Minerals present may include aluminum, arsenic, boron, cadmium, chromium, cobalt, copper, fluorine, iodine, lead, mercury, molybdenum, nickel, selenium, sulfur, and vanadium. The Minerals Scheme is available worldwide. The 2026 subscription cost is $540 + shipping.
Dietary Fiber Quality Reference Material (QRM) Study
Participating laboratories will receive two (300g) samples of ground dog food to analyze for dietary fiber using their chosen method(s). Participants will conduct the analysis in duplicate upon receipt of the sample, again after 30 days, and again after 60 days for a total of six (6) results. The results will be reported in the [DRW Portal] along with the results of the dog food sample. In addition to the submission of the results for dietary fiber, participating laboratories will submit the results for the controls β-Glucan and Wheat Starch for each run. The results of these controls will help ensure the absence of undesirable enzymatic activities. All controls and the reference sample will be provided by AAFCO.
The results will undergo statistical analysis using the same methodology applied in AAFCO’s regular PTP schemes. Remaining material will be available for purchase by laboratories to support the development and implementation of dietary fiber methods.
Cost: $50 per laboratory (includes sample, controls, enzymes, & additional Dietary Fiber QRM sample).
Additional Dietary Fiber QRM Samples:
Current PT Subscribers: $55/sample
Non-Participating Laboratories: $110/sample
