NE Iowa | Keep hearing about worm resistance to Ivermectin pour on but it is so darn cheap and easy to use it is hard to switch to anything else. Cows get poured at preg check time (November) and again in the spring when the get vaccinated prior to turnout (Late April / Early May). Calves get poured at turnout, early fall when getting preweaning vacs, and again in spring while in feedlot. | |
