A bit of a spinoff from the StrategyT thread. Everybody's responses got me wondering about the different worming regimes people use. How often do you worm? What brand do you use? What brand do you rotate with? How often do you rotate? Do you test manure for worm burden? Do you use 'alternative' methods of parasite control as a substitute or to compliment your wormer, and if so what do you use? Do you drench? How often?
