Abstract
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.

Further, and more detailed, information about data collection, handling, and analysis is contained in the manuscript in which the data is published in the Journal of Regulatory Sciences DOI: https://doi.org/10.21423/JRS.REGSCI.121293 (JRS-2024)
Files and variables
File: AssessingErrorAnalyteData.xlsx
Description:
File contains 40 probes each of 8 feed types identified as 1mineral, 2_Layer, 3_beef, 4_SBM, 5_Sheep, 6_DDG, 7_Game, and 8_Dog. File contains data on crude protein in percent (Cp_per), selenium in ppm (Se_ppm), calcium in percent (Ca%), cobalt in ppm (Co_ppm), copper in ppm (Cu_ppm), iron in ppm (Fe_ppm), potassium in percent (K_%), magnesium in percent (Mg_%), manganese in ppm (Mn_ppm), sodium in percent (Na_%), phosphorous in percent (P_%), zinc in ppm (Zn_ppm), and lasalocid in grams per ton (Lasalo_g/ton) where applicable. The ‘n/a’ signifies that an analyte result was not available due to not being tested using a using a specific method. Less than LOQ (<LOQ) indicates that the test result was below the lower limit of quantification.
- Feed types: 1_mineral, 2_Layer, 3_beef, 4_SBM, 5_Sheep, 6_DDG, 7_Game, and 8_Dog
File: RandomNumberSets.xlsx
Description:
File contains 6 randomization sets containing 40 numbers each. These randomized numbers were applied to the 40 cores of each feed type, and the cores were reordered according to the random number set low to high, to achieve the randomization on the data set.RandomNumberSets.xlsx
This dataset was generated from protein, mineral(s), and drug analysis on 40 cores from each of 8 feedstuffs (320 individual cores).
