Four calves of similar age and weight were allocated to two groups, one group was treated subcutaneously with ivermectin and the other group remained as untreated control. From faeces collected from both groups at 3, 7, 14, 21 and 28days post-treatment (dpt), three faecal pats of 1kg each were made and deposited on a mixed paddock. One quarter of each faecal pat was removed at 10, 20, 30 and 60days postdeposition (dpd) to determine the concentration of ivermectin, the organic matter content, and to collect colonising dung arthropods. Concentrations at days 3 and 7pt were significantly higher than at the other dpt (p < 0.05). The highest ivermectin concentrations were found in samples from 3dpt (p < 0.05). The organic matter percentage was not significantly different between treatments. An edaphic fauna characterised the colonisation of the faeces by organisms. Although arthropods' abundance differences were not significant except for the 28dpt at 30 dpd (p < 0.0003), fewer organisms were collected from the ivermectin group at all times.
