The severe use of anthelmintics to control gastrointestinal nematodes has become an essential issue in many countries, especially related to resistance issues. A study was carried out to determine the anthelmintic resistance status of intestinal nematodes of sheep, which were kept intensively in Bogor District, Indonesia. A total of 220 sheep of 7 breeds that routinely received Benzimidazole anthelmintics group to control gastrointestinal nematode were designated for this study. The animals were divided into 7 groups based on the breed and treated with Albendazole at the required dose. The Fecal Egg Count Reduction Test (FECRT) method was used to evaluate the anthelmintic's effectiveness. The mean fecal egg count reduction was recorded at seven and fourteen days of treatment. The result indicated that 7 breeds of sheep were resistant to the anthelmintic used. Garut Local and Barbados Cross breeds showed relatively high resistance to Albendazole, with the mean fecal egg count at fourteen days of treatment being 60.24% and 67.97%, respectively. Haemonchus spp. larvae were the nematode larvae of strongyles species that grew the most in each breed of sheep from the fecal samples on day 0 (before treatment), day 7, and day 14 after treatment.
