| description |
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<0.05) for the whole experimental period too. Abundance and
diversity of arthropods was reduced in samples from treated group (p<0.05). This
effect was marked when comparing adults and larvae of nematocera and braquicera
diptera and gamasida, actinedida and acaridida acari. Other groups of organisms
showed reduced parameters without statistical significance. Also, the highest
reductions in abundance and diversity were obtained in fecal samples of treated
group at 1, 3 and 7 dpt in agreement with the highest concentration of ivermectin
and the highest organic matter percentage. Consistently, the ivermectin eliminated by cattle treated in autumn affect the faecal natural colonization of dung and
delays the faecal degradation in the environment |
