Important Management Practices

Dipping
  • To control the ecto-parasites, sheep should be dipped 10-15days after shearing when they have grown sufficient new wool to hold the chemical substance and shearing wounds have healed up.
  • Dipping is the most efficient practices for treating sheep for skin parasites. Animals should be submerged in the dippingfluid at least 1 minute.
  • The head should be submerged at least 3 times.
  • Dip the sheep in one pen and make sure that they have wetted thoroughly, especially the neck folds and skin at back of the neck.
  • Dip young and healthy sheep first.
  • Do not place ewes and lambs in the tank simultaneously.
  • It is very important not to dip thirsty sheep.
  • Start dipping early in the morning and do not continue until late in the afternoon.
  • Sheep should get the opportunity to dry off sufficiently before the evening.
  • Watch the weather and avoid dipping if there is a possibility of rain or cold weather
  • There are standard designs for sheep dips (as shown in figure besides)
  • There are two broad classes of sheep dip: organophosphorus compounds, and synthetic pyrethroids. Malathion is one of the safest organophosphates because of its selective toxicity; it is highly toxic to insects but much less toxic to mammalian species.
  • Use nearly 900ml of Malathion to 100 litres of water for dipping to control ticks etc. A local Veterinarian must always be contacted before preparing the dipping solution, for safety.
