Internal parasites can cause a number of problems to your stock, especially young animals.

Here are a few clinical signs to store in the back of your mind that should ring ‘worms’ when you notice any in your own animals…

  • Diarrhoea
  • Poor growth rates/losing weight
  • Pale mucus membranes
  • A pot-bellied appearance
  • Not eating as much as normal
  • Fluid build-up under the jaw (‘bottle jaw’)


Generally young animals should have their first drench at weaning, and then a further five drenches at monthly intervals. This is known as ‘preventative drenching’.

Other strategies that help decrease the worm burden on animals include:

  • Having an appropriate stocking rate – too many animals in one paddock increases the worm burden in the grass.
  • Making sure animals don’t graze pasture that is too short – worms hang out at the bottom of the sward.
  • Mixed species grazing – for example having lambs graze with cattle.
  • Ensuring your stock are well fed and in good body condition.


If you are noticing your animals are not doing as well as you would like, and they are showing some of the signs above, come in and have a chat with us. We can devise a specific parasite control strategy that is unique to your property, and recommend the most appropriate drench for you.
