Where should feed samples be collected from a bulk delivery truck to test for particle size distribution and mycotoxins?

When a bulk feed delivery truck arrives at a commercial layer farm, checking feed quality before unloading is a vital quality control step. Feeds are prone to segregation during transport, where heavy minerals settle to the bottom and light fiber rises to the top. To obtain a representative sample, technicians must use a long, multi-chambered grain probe (trier). Samples must be taken from at least five distinct cross-sectional points (center and four corners) across the top, middle, and bottom of every compartment in the bulk truck. Collecting only from the unloading gate or the top surface will produce skewed results for particle size analysis and can miss localized mycotoxin hot spots. Farmers can study feed sampling and quality control in the Poultry Encyclopedia, purchase manual grain probes and mycotoxin test kits on Poultry Plaza, monitor raw feed commodity rates on Poultry Rates, and trade certified feeds on Murghi Mandi.
