Second, weigh cattle to determine accurate dosing and help achieve more effective treatment. Using too much or too little product can result in a wasted parasite control investment or less-than-ideal control.
Third, producers should work with their local veterinarian to help determine the best time to control parasites in their area. Obviously it is better to treat than not, but your veterinarian will know when the treatments will be most effective for your area.
Fourth, use parasite control products based on the region and life cycle of the target parasites. Due to the persistent effect of endectocides, treatments can be applied in northern climates two to three weeks before or after the first hard frost for the best fall and winter control. Where liver flukes are a concern, fall is an ideal time for treatment.
Finally, use a branded product that is backed by a product satisfaction guarantee
