Parasite Control

Help Cattle Gain More Weight with Sustainable Parasite Control Strategies

Internal and external parasites reduce herd performance and productivity. Infested cattle experience reduced appetite, grazing, feed intake and conversion, resulting in lower average daily gains. Parasites can also have a negative impact on immunity and reproductive performance.
