Abstract
Recent reports seem to indicate that the use of certain anthelmintics in cattle may cause adverse effects on non-target faunal inhabi-tants of cow pats, thus interferring with the normal degradation and recycling of dung deposited on pasture (Anderson et al. 1984, Lumaret 1986, Wall & Strong 1987). The present communication presents some data from a microcosm experiment on the pos-sible effects of some commonly used anthel-mintics on the rate of cow dung decomposition.
