  • Sheep experimentally infected with [0551] Haemonchus contortus were treated after expiry of the prepatency time of the parasite. The active compounds were administered orally and/or intravenously as pure active compound.
  • The degree of effectiveness is determined by quantitatively counting the worm eggs excreted with the faeces before and after treatment. [0552]
  • Complete cessation of oviposition after treatment means that the worms have been expelled or are so damaged that they no longer produce eggs (effective dose). [0553]
  • Active compounds tested and effective doses can be seen from the following tables. [0554]
