Key points
- AHDB describes faecal egg counts in eggs per gram as a tool supporting worm-control decisions.
- Sampling and post-treatment checks help assess control; unnecessary treatment can contribute to resistance.
- New arrivals and grazing history belong in the health record, alongside local veterinary advice.
Parasite management needs evidence, not just a calendar. Keep sampling, treatment checks and incoming-group records together before planning delivery.
Move from a date to a decision
AHDB’s sheep worm-control guidance and linked 2024 handbook explain monitoring within an integrated programme. Its farming context is the UK; other regions need locally appropriate veterinary interpretation. A planned delivery date is useful for logistics, but it does not by itself determine whether a group needs treatment.
What a count can and cannot show
A faecal egg count reports eggs per gram, usually abbreviated epg. It supports decisions and checks of treatment performance, but a single result is not a diagnosis of every parasite risk. AHDB highlights limitations, including early disease caused by immature Nematodirus larvae before significant egg output. Clinical signs and local risk information therefore remain important; this article gives no dosing or treatment prescription.
Make incoming-group records usable
Our recordkeeping recommendation is to connect the source flock, arrival date, grazing history, sampling date, result and veterinary plan in one group record. Keep purchased sheep and their management history identifiable. Do not assume that a recent treatment guarantees success: retain the product and treatment information so the veterinarian can decide which follow-up is appropriate.
Connect health records to delivery planning
Before dispatch, review the group’s condition and the applicable veterinary and medicine-withdrawal requirements. Share necessary movement and food-chain information with the receiving operator. For an equipment brief, describe group sizes, arrival patterns and holding arrangements separately from treatment decisions. A slaughter-line supplier can discuss receiving facilities; parasite diagnosis and medicines remain veterinary responsibilities.
Practical question
Is a low faecal egg count proof that a sheep group has no parasite problem?
No. Interpret the count alongside clinical signs, parasite type and local risk with a veterinarian. Some important risks are not reliably excluded by one count.
