Faecal Worm Egg Counts And Drench Testing

Worm burdens can cause significant production losses in livestock, including reduced body condition, scours/diarrhoea, poor feed conversion rates and even death. Here at Kojonup Veterinary Hospital we offer our services and advice to help assess the presence and burden of worms and drench outcome/effectiveness. 

Faecal Worm Egg Counts

Faecal Worm Egg Counts (FEC) are an important tool in assessing the worm burden of your animal. FEC's are also a valuable tool in ensuring the drench treatment that is being used for worm control has been effective.

Here at Kojonup Veterinary Hospital we perform FECs in sheep, cattle, horses and alpacas.

Drench Resistance Testing

Minimising unnecessary drenching in flocks is strongly recommended by the Western Australian Department of Agriculture  to help reduce worm resistance. Drench Resistance Testing allows us to examine the effectiveness of an individual drench on the worm burden in an individual or a group of animals. It allows us to assess if there is resistance in worms against an individual drench (or if the worm egg count is not reducing properly/at a suitable rate).

What does Drench Resistance Testing involve?

A drench resistance test involves:

  • Taking a sample of faeces before drenching and bringing these in for a FEC
  • AND a sample of faeces 10-14 days post drenching and bringing these in for a FEC
