Flystrike is caused when blowfly eggs, laid on your animal hatch, and maggots start to eat the flesh.
Flystrike can have severe outcomes if not managed appropriately. The following recommendations should help to keep your flock at lower risk this summer.
Risk Factors:
- The most commonly affected farm animals are sheep more so these with a significant parasite burden, diarrhoea or wounds
- Dirty Wool
- Warm, humid conditions
Signs:
- Fidgeting/itching, you may notice your sheep rubbing their coat out
- Blood staining/darkening of the fleece next to affected areas
- Sores, especially under the tail or shoulders/forearms with maggot activity. These sores may have a putrid smell
Prevention:
- Many farmers choose to tail dock to reduce faecal build up
- Regular health checks, ensuring you check the most common sites of infestation
- Good parasite control
- Good hygiene
- Keep sick/scouring animals inside away from flies.
- Shear fleeces in warm weather
- Shear + clean affected areas if not done so already
Treatment:
- Isolate affected animals
- Examine sick animals daily removing maggots and applying appropriate topical treatment
- Speak to your vet about the use of certain drugs active against ectoparasite + flies
