Resumen:
Aim: Intestinal parasites are one of the most common problems in sheep
production systems. However, the strategies used to eliminate these
parasites have not yielded satisfactory results. Therefore, the aim of
this study was to determine the effect of five anthelmintics (with
different active ingredients) on the parasite load in sheep.
Materials and Methods: In this study, 107 Rambouillet breed sheep were
randomly assigned to five groups. Next, fecal samples were taken
directly from the rectum and sent to the laboratory for analysis. We
then dewormed each group of sheep using different anthelmintic products:
Ivermectin 1%/clorsulon 10%, levamisole 12%, closantel sodium 5%,
ivermectin 10%, and closantel 5%/albendazole 3.75% with a dosage
corresponding to each sheep. At 15 days post-treatment, we took fecal
samples and performed a coproparasitoscopic study, using the Faust
flotation technique to assess the presence or absence of parasite eggs
and the McMaster technique to quantify eggs.
Results: Ivermectin/clorsulon was more effective in eliminating
parasites than other anthelmintics used, especially in Haemonchus spp.
Conclusion: The results of this study indicate that using
ivermectin/clorsulon decreases the number of eggs in feces and is one
alternative in controlling parasites in sheep, leading to a reduction in
the incidence of health problems, and consequently, improved
productivity.
