Assessing Error upon Sampling Bagged Animal Feed

The University of Kentucky Division of Regulatory Services explored the adequacy of the AOAC Official Method 965.16 for sampling bagged animal feed and assessed the acceptability of the sample error introduced through the sampling process. Eight feedstuffs were selected to represent a variety of feed forms, and their inherent differences in component size, with the objective of estimating the acceptability of the error introduced in the sampling process for each analyte. The findings suggest that the AOAC Official Method 965.16 is suitable for use in the collection of samples for regulatory purposes, particularly concerning mineral and drug components. The study's analysis and methodology provide valuable insights into the adequacy of the sampling method for regulatory purposes.
