Article Synopsis
- This study aimed to evaluate a targeted selective treatment (TST) method for Morada Nova lambs based on their average daily weight gain (DWG), comparing it with control and routine treatments over different seasons.
- Results showed that TST led to better resilience against anthelmintic resistance and effectively managed lamb health without significant productivity losses.
- Overall, TST promoted sustainability in sheep breeding by maintaining genetic diversity through refugia, which helps reduce parasite resistance development.
This study evaluated the resistance status of Haemonchus contortus from sheep flocks in the state of São Paulo, Brazil, through comparison between the fecal egg count reduction test (FECRT) and the larval development test (LDT). For the FECRT, 35 sheep were selected in each of five flocks and divided into groups treated with: benzimidazole, levamisole, ivermectin, monepantel and control. Feces were collected for EPG and fecal cultures.
