A research project was conducted to determine which type of fabric swatch was best suited for on-site sampling of odor intensity at open-lot beef cattle feeding operations. Five different types of fabric were tested: cotton flannel, cotton muslin, acetate, polyester and polyester felt. Square swatches (20 × 20 cm) were suspended 1 m above the ground surface downwind of cattle pens for 24 hours. The swatches were placed in glass jars and presented to 8-10 human panelists who were asked to rank the swatches based on relative odor intensity. Five trials were conducted at 3 feedyards. Sums of ranks and …
