Fig. 4. Effect of (A) sample mass and (B) volume on measured dust potential (mass of dust on the filter after 15 s of vacuum collection during blender operation) from four feedlot samples. The SE of the least squares mean (n = 3) for dust potential is 17.5. The range of maximum dust potential for each sample is defined as the range of masses (or volumes) that produced a dust potential that did not differ (P > 0.01) from the maximum dust potential measurement.
