				Abstract 
 
              
              
              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.
