“Strategic deworming” refers to the timing and approach used to deworm your herd of cattle, and it’s based on climate and the type of parasite challenge you have.

It is recommended to deworm cows in the fall after they’re removed from pasture, and then again in the spring about six weeks after turn-out. Calves usually only need it done in the spring or early summer, depending on your climate. While you’re at it, go ahead and take care of other tasks that require handling, such as tagging and vaccinations.

If you are wondering when to deworm in the spring, the perfect time is when the grass starts to turn green in your area.
Broad-spectrum products are great for controlling both external and internal parasites. Make sure you follow the directions on the label and ask a vet if you need more information.
