Abstract	This study was conducted to evaluate anthelmintic resistance (AR) in gastrointestinal nematodes of cattle raised in selected communities in Echague, Isabela, Philippines. The development of AR was evaluated using Fecal Egg Count Reduction Test (FECRT) and the prevalence of parasite before and after dewormer administration of 90 heads of cattle. Results show that Haemonchus spp. was the most prevalent gastrointestinal parasite, occurring in 100% of cattle before and after treatment, while Trichostrongylus spp., Moniezia spp., and Trichuris spp. were eliminated following deworming. Although fecal egg counts significantly decreased after treatment (mean reduction = 43.03 EPG; p = 0.000), FECRT results indicated that overall fecal egg count reduction was below the recommended 95% threshold. Moreover, 78.9% of the cattle were classified as resistant, confirming the presence of widespread anthelmintic resistance in the study area. The study concludes that anthelmintic resistance is already prevalent among cattle in Echague, Isabela.
