ISSUE FOCUS 56 FEED & ADDITIVE MAGAZINE March 2024 To take ‘dynamic’ or moving material samples during the manufacturing process: • Drill a hole of approximately 1.5 inch in diameter in the bottom of the conveyor that carries the ground raw material to the storage tanks for mixing. • Connect a pipe with a stopcock to this hole. • For every 30 MT that pass, take at least 10 kg of sample by opening the valve and dropping product through the pipe/tube into a sampling container. • Proceed with the preparation of the sample as explained for the raw material reception area (21 samples of 200 g). Tip: Make sure the sampling pipe is easily accessible for cleaning. Also, wash and disinfect the sampling containers to avoid contamination. 4. From feeders in the farm After distributing feed on the farm, employ specific methods for accurate sampling. We recommend 2 possible methods for feeder sampling in poultry and pig farms: • Take a 50 g feed sample for every 100 m2 in poultry farms. In pig farms, take 50 g from each feeder. Mix the samples and divide (as explained above) to obtain a final volume of 500 g for lab testing. or • Divide the house into 10 equal sections and take a 100 g sample from a feeder in each section. Mix the 10 samples of 100 g to obtain 1 kg. Send half of this sample (500 g) to the lab for testing. CONCLUSION Considering the unique challenges associated with mycotoxin detection, proper sampling techniques are crucial to obtaining accurate results. Following these guidelines ensures a comprehensive and representative analysis, contributing to effective mycotoxin management in grains and feed.
