Abstract

The objective was to verify the existence of antihelminthic resistance in gastrointestinal nematodes of sheep in properties of the municipalities of Janaúba and Nova Porteirinha. The experiment was conducted at 4 properties, and was done as coproparasitological analyzes in fecal samples of 88 animals. In the farms (A and B) there was a division of the animals into two groups: control and immersion and in farms (C and D) in three groups: control, ivermectin and albendazole. Each group has 6 animals. The reduction of fecal grain contamination (RCOF) was determined based on the specific formula, indicating a percentage greater than or equal to 95%. There was resistance of the gastrointestinal nematodes to albendazole in the two properties in which it was tested and ivermectin in three of the four properties. In farm C, ivermectin showed efficacy of 97%. The most prevalent nematode was Haemonchus contortus.
