@Ridgetop you do realize that both Cydectin and Zimectrin are in the same class of wormer.. so you basically wormed them with the same thing... sometimes the formulation is different, and sometimes a second drug may be added such as clorsulon(SP?) which is effective against liver flukes... You have to switch to Valbazen or Prohibit ... they are each a different class of wormer and will affect the sheep in a different manner.
