Why quarantine is part of the purchase
Paying and loading the trailer feels like the deal is done. For the animals already on your place, the risk starts the moment the new ones step off.
A short isolation period is not distrust of the seller. It is a buffer for diseases that hide in healthy-looking stock: orf, caseous lymphadenitis, lice, resistant worms, and respiratory bugs that flare after transport stress.
Three weeks is the usual minimum. Thirty days is better if you bought from mixed sources or the animals travelled a long way.
What quarantine is (and is not)
Quarantine means no shared air, no shared water, no shared tools, and no shared pasture with resident animals.
It is not a spare stall in the same barn with a gap under the door. It is not a paddock next to the herd with one fence line. Nose-to-nose contact through wire still moves orf and respiratory viruses.
Minimum setup that actually works
- A pen or small paddock at least 10–15 metres from resident stock.
- Its own water trough and feeder. Do not borrow buckets from the main barn.
- Separate boots or a disinfectant mat at the gate.
- Handle quarantined animals last each day, then wash hands and change outer layers.
- Shade, dry bedding, and wind protection. Stressed animals shed more pathogens.
If you only have one barn, use the far end, block shared alleys, and treat the isolation area as a one-way zone.
Day 0: what to do when they arrive
Do a quiet exam before they mix with anything on your farm — including the farm dog.
- Count animals against the bill of sale and note ear tags or microchips.
- Check eyes, noses, mouths, and feet. Look for scabs on lips (possible orf), swollen lymph nodes, lameness, and dirty rear ends.
- Weigh or body-condition score if you can. A thin animal needs feed before it needs new neighbours.
- Offer water first, then hay. Save grain for the next day unless they are used to it.
- Photograph any existing wounds so you can track healing.
Write one page of notes. Memory fades after the second week.
The 21–30 day calendar
Days 1–3: settle and watch
Transport stress drops immunity. Watch for coughing, isolation from the group, not drinking, and diarrhoea. Call a vet early if breathing is hard or an animal will not stand.
Keep feed simple: forage they recognise, plus a mineral mix suited to the species. Sudden rich grain after a long haul is a good way to trigger acidosis in ruminants.
Days 4–10: parasites and skin
This is the window for a faecal egg count if you have a lab or clinic that will run one. Treat based on results, not habit. Blind deworming is how resistance spreads.
Check coats for lice and mites. Goats and sheep often arrive with a light infestation that explodes after the stress of moving. Treat the isolation group only, and bag or burn bedding after treatment.
Trim overgrown hooves if the seller did not. Footrot needs isolation even from other quarantined animals.
Days 11–21: tests that catch slow problems
Talk to your vet about tests that match the species and your region. Common choices:
- Caprine arthritis encephalitis (CAE) and caseous lymphadenitis (CL) in goats
- Ovine progressive pneumonia and CL in sheep
- Johne’s disease where it is present in local herds
- Brucellosis or TB only if your vet or movement rules require it
A negative test on day 1 is useful. A second test near the end of quarantine is stronger, because some infections take time to show on bloodwork.
Days 21–30: the join decision
Do not mix on a calendar date alone. Mix when:
- Appetite and manure look normal for at least a week
- No new scabs, coughs, or swollen nodes
- Parasite plan is done and recorded
- You have handled them enough that they will not panic in the main group
Introduce on neutral ground if you can — a fresh paddock neither group owns. Watch the first hour. Separate again if fighting is severe or one animal is pinned.
Tools and people: stop carrying the problem yourself
Most quarantine failures are human. The same shovel moves manure both ways. The same coat picks up orf scab material.
Keep a cheap set of tools that never leave the isolation pen: fork, bucket, thermometer, halter. Colour-code them with tape.
If children or hired help feed morning and night, write the order on the gate: resident stock first, isolation last, wash after.
Dogs and barn cats should not free-range between groups. They walk through manure and under fences.
Special cases buyers keep missing
Pregnant females. Quarantine still applies. Do not park a late-pregnant ewe or doe next to a noisy weaner pen. Stress and abortion risk go up. Plan a quiet isolation space before you bid.
Bottle babies and orphans. They look harmless and they are not. They often come from mixed farms and get handled by many people. Keep them off the main bottle-kid area until the seller’s health story checks out.
Poultry with ruminants. A new trio of hens does not belong in the goat quarantine pen. Birds carry different pathogens and will dirty water the ruminants drink.
One animal from a large sale barn. Treat that single head as high risk. Sale-barn stock meet more animals in a day than a closed farm meets in a year.
What to ask the seller before you need quarantine
Good isolation is easier when the history is clear. Before you pay, ask:
- When were they last dewormed, and with what product?
- Any abscesses, coughs, or sudden deaths in the last year?
- Vaccination dates (clostridial vaccines at minimum for small ruminants).
- Were they commingled with other farms in the last 60 days?
Sellers who answer in specifics are easier to work with than sellers who say “everything is fine.” Save the messages. They help your vet if something surfaces in week two.
A short buyer checklist
- Isolation pen ready before the trailer arrives
- Own water, feed, and tools
- Written arrival notes and photos
- Faecal test planned in week one
- Species-specific blood tests booked with your vet
- 21–30 days with no shortcuts for “they look great”
- Mix on neutral ground and watch the first contact
Quarantine does not make every purchase safe. It makes most purchases survivable for the animals you already spent years building. That is the part of the deal that does not show on the listing price.
