Dr Ginny Dodunski highlighted how Cooperia and Ostertagia are now often resistant against triple active drenches. There are management options possible to reduce or avoid regular drench use without loss in growth. from holistic approaches with stock management, and strategic drench use there can still be impacts on performance due to the challenges around parasites. However weight gain can be at or even above MINDA target without the use of drenches. With the combination of strategic management and effective nutrition, production can still be achieved and in some cases increased. Balancing the diet and allowing additional energy to overcome the body’s natural energy use when fighting off infections, parasites or inflammation, means that liveweight targets can still be achieved. In some cases, no daily larvae challenge will be combatted by drench use! It’s all about nutrition!
