Abstract

Two studies were conducted to evaluate the potential consequences of exposure of cattle to rainfall following treatment with Cydectin, a pour-on formulation of the endectocide compound moxidectin. The objective of the first study was to evaluate the potential effect of rainfall on the efficacy of Cydectin Pour-On against gastrointestinal roundworms as determined by fecal egg counts. The objective of the second study was to quantify the amount of moxidectin, if any, which would wash-off from treated cattle following a heavy rain event (2 inches/hour).
