Economic Viability Analysis of an Oral Anthelmintic Treatment for Cattle in Feedlot

The economic viability of a commercial oral anthelmintic suspension containing 10% fenbendazole was evaluated in Angus x Nelore cattle feedlot. Two groups 37 animals (treated and non-treated) were formed. A random-block design used based on initial weight, egg count per gram feces (EPG) carcass grade. EPG counts the determination weight performed Days 0, 42 122. Carcass grade yield determined day slaughter. Economic using cost-effectiveness, sensitivity financial analyses, considering three scenarios: most likely (M), optimistic (O) pessimistic (P). achieved 99.89% efficacy regarding reduction. exhibited an increase 20.7 kg live 20.2 gain 0.166 daily (p < 0.05). No effects found or > genus Haemonchus predominated at onset study, whereas only Cooperia after treatment. net return 14.60 USD animal treated group, which remained viable under O, M P scenarios, with respective differences 18.92%, 12.86% 91.15% gross profit. treatment financially superior all scenarios (real, M, O P), reductions 1.89, 1.04, 0.48 16.39 years for recovery investment. These results demonstrate importance analysis methods evaluation selection anthelmintics.
