Does your current cattle vaccination regime include a dewormer? If not, you may want to consider adding it. Pour-on topical dewormers, like Ivermectin, serve as an effective way to help control and manage internal and external parasites in your cattle.
Ivermectin is cost-effective and a little application goes a long ways in keeping your cattle healthy. Dosage is based on the weight of your animal(s). Using an applicator gun, this dewormer is easy to apply right in the chute, along with your other vaccinations.
We run all of our cattle through our cattle facility every fall for vaccinations, including Ivermectin. Applying a dewormer in the fall-time works best for our operation, as lice can often be a problem during the winter months. Our winters start early and last a good six months, at the minimum. Further, depending on how bad the flies are in the summer, we will often apply a broad spray application to the cattle right in the field, using a back-pack sprayer.
