16.3.4 Cost of Anthelmintic Resistance
Anthelmintic resistance is nearly undetectable by owners without doing faecal egg counts, unless the percentage of resistant adults in the parasitic population reaches very high levels. But even invisible, anthelmintic resistance has economic consequences. This was demonstrated in sheep by Sutherland et al. (2010). These authors compared weight gains of lambs treated with an anthelmintic fully efficient and weight gains of lambs treated with an anthelminthic showing efficacy from 40 to 50% and reported significant weight losses due to anthelmintic resistance. No similar experiment has been conducted in goats.
