Popis: A trial was carried out to evaluate the effect of the ivermectin eliminated in the feces of treated calves on the coprofaune and on the physical degradation of dung pats naturally deposited during the autumn in the Tandil zone. Two experimental groups, located in different paddocks, were used. One group was treated subcutaneously with ivermectin (0,2 mg.kg) and the other remained as control group. The spot where feces were naturally evacuated in day 1,3,7,14, and 21 post treatment (dpt) was clearly identify. Fecal pats of each group were sampled at 1,3,7,14,21,30 and 60 days post deposition (dpd). The ivermectin concentration and organic matter percentage were determined and the arthropods present were collected. All the fecal samples of the treated calves presented drug, being samples on 1 and 3 dpt samples those with the higher concentration and higher organic matter content (p
