Worming & Parasite Control

Worm Egg Count Samples

A faecal or worm egg count (FEC/WEC) is the process of counting the number of worm eggs in faeces (dung) and is used to monitor the worm burden in sheep or cattle.

The results are presented as ‘eggs per gram’ (epg) of faeces and the number of eggs is an indication of the number of adult worms in the gut of the animal.

How to take a pooled WEC sample

  • Collect fresh faeces from a warm dung pat on the ground
  • Collect approx. 40g (four heaped dessert spoons)
  • Place samples in individual bags or plastic pots which are free from the practice
  • No not mixed the samples. Take ten separate samples per management group.
  • Label the samples with as much information as possible: – Age of animals
    • Number of animals in the group
    • Condition of the animals
    • Date of collection
    • Date of last wormer use and product used
  • Store samples in a fridge and deliver to the practice within 24 hours of collection

    WECs can be used to evaluate:

    • Do you need to treat or not?
    • Has previous treatment worked?
    • Are there any signs of resistance in your flock/herd?

Fly Control

Garston Vets are offering a NEW service in an attempt to combat the high burdens of flies on farms and subsequent problems seen, such as New Forest Eye and summer mastitis.

This natural fly control works by distributing parasitic wasps/flies/mites in high-risk areas. These insects feed on the fly larvae reducing the overall population of flies on the farm.

We are fast approaching the start of “fly season”, so if you are interested or want to know more, please contact the practice. We can discuss options & provide quotes for a plan tailored to your individual farm.
