Effects of Treatment of Cattle with some Anthelmintics on the Subsequent Degradation of their Dung

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.
