The effective use of pooled oral fluid (OF) in disease surveillance requires that samples are representative of the group. The aim of this study was to develop a 'rope presentation' protocol to maximise the number of different pigs sampled from a pen of animals. Eight pens of grower pigs in 'fully slatted' accommodation (FS) and 'straw-kennels' (SK) were presented with a balanced sequence of 1-4 ropes. Ropes were presented for 60 min, and the chewing time/pig recorded. Oral fluid was extracted from all of the ropes. Rope provided for 60 min generated chewing in >80% of the group. Pigs in SK exhibited longer latency to interact with the rope (P < 0.001), reduced percentage of pigs chewing (P < 0.001), and a reduced mean total time spent chewing (P < 0.001). An interaction was found between 'system' and 'number of ropes provided' (P < 0.05). Increasing the number of ropes increased the mean total chewing time/pig only in the FS. The quantity of OF obtained correlated with the percentage of pigs that chewed the rope (P < 0.001) and the mean total time spent chewing/pig (P < 0.001). Where the group size was <= 25, presenting one rope for 45 min was sufficient to optimise the number of pigs sampled. (C) 2011 Elsevier Ltd. All rights reserved.
