Goat Quarantine Facility Design: Preventing Disease Introduction

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

A minimum 30-day quarantine for all new goats is critical, with 60 days recommended for high-risk animals or valuable breeding stock to allow for incubation periods of diseases like Caprine Arthritis Encephalitis (CAE) and Johne's disease.
Physical separation of at least 20 feet, utilizing separate buildings or pens with solid barriers to prevent nose-to-nose contact and shared airflow, is essential to mitigate aerosol and direct contact transmission routes.
Dedicated handling equipment, feed/water containers, and personal protective gear (boots, coveralls) for the quarantine area, coupled with a strict "work last" protocol for quarantined animals, prevents pathogen cross-contamination.
Daily health monitoring for attitude, appetite, manure consistency, and temperature (normal 102-103°F, fever >103.5°F) is paramount, alongside diagnostic testing (e.g., ELISA for CAE, fecal egg counts for parasites) at arrival and near the end of quarantine.
Proper waste management, including composting manure for at least six months, and thorough cleaning and disinfection of the facility between groups are vital to eliminate environmental pathogen reservoirs.

Bringing new goats onto your property is one of the highest risk moments in herd management. A single new animal can carry pathogens that spread quickly through an established herd, causing illness, lost production, and in severe cases, death. This guide covers how to design and operate a goat quarantine facility that protects your existing animals from disease. It is written for small to mid-size goat producers, homesteaders, and farm managers who want practical, workable solutions for isolating new arrivals and sick animals.

The information here walks through the reasons quarantine matters, how to design a facility that fits your property, the daily operating procedures that make quarantine effective, and how to decide when it is safe to introduce a goat to the main herd. You will also find guidance on recordkeeping, monitoring, and when to call a veterinarian or extension agent for help.

At a Glance

Quarantine every new goat for at least 30 days. A 60 day period is better for high risk animals or when you have valuable breeding stock.
Keep quarantined goats at least 20 feet away from your main herd. Use a separate building or a pen that cannot share air, feed, or water.
Use dedicated tools and boots for the quarantine area. Clean and disinfect them before they leave the area.
Work in the quarantine area last. Feed and care for your main herd first, then tend to quarantined animals.
Test for common diseases before purchase and again during quarantine. Work with your veterinarian to decide which tests are right for your herd.
Watch quarantined goats daily for signs of illness. Track temperature, appetite, manure consistency, coughing, and nasal discharge.
Keep a written log for every goat in quarantine. Record arrival date, source, test results, treatments, and observations.
Do not let quarantined goats share fences, feed, water, or handling equipment with the main herd.
Have a separate set of clothing and boots for the quarantine area or use disposable coveralls and boot covers.
Call your veterinarian if a quarantined goat shows signs of contagious disease, has a fever over 103.5 degrees Fahrenheit, or stops eating.

Why Quarantine Is Essential for Goat Biosecurity

Goat biosecurity is the set of practices that prevent disease from entering your herd and stop disease from spreading if it does get in. Quarantine is the cornerstone of that system. It is the single most effective step you can take to protect your existing goats from new arrivals.

New goats carry invisible risks. A goat can look perfectly healthy and still shed pathogens. Some diseases have incubation periods of weeks. Others can be carried by animals that never show symptoms. Caprine arthritis encephalitis (CAE), caseous lymphadenitis (CL), and Johne's disease are all examples of serious goat diseases that can be present in an animal that appears healthy. Internal parasites are another constant threat. A new goat can introduce drug resistant barber pole worms (Haemonchus contortus) to a pasture where your current herd has low parasite loads.

The physical separation of quarantine gives you time to observe new animals, run diagnostic tests, and treat problems before they have any chance to reach your main herd. It also gives the new goats time to adjust to your feed, water, and climate without the stress of competing with established animals. Stress suppresses the immune system, which makes goats more susceptible to disease. A quiet quarantine period actually helps new animals stay healthier.

Quarantine is not just for newly purchased goats. It is also for any goat that leaves your property and returns, such as goats taken to shows, fairs, breeding loans, or veterinary clinics. These animals have been exposed to other goats and to shared equipment. Treat them the same way you would treat a new purchase. A goat that left your farm for a weekend show should be quarantined when it returns.

Goats that are sick or injured also benefit from isolation. A goat isolation pen is different from a quarantine facility for new arrivals, but the same space can serve both purposes if you clean it properly between uses. Isolating a sick goat protects the rest of the herd from whatever it has and gives the sick animal a quiet place to recover.

Designing Your Goat Quarantine Facility

A goat quarantine facility does not need to be expensive or elaborate. It does need to meet several key requirements. The design should prevent nose to nose contact between quarantined and main herd animals, prevent shared air flow in enclosed spaces, make cleaning and disinfection simple, and give the quarantined goat a comfortable, low stress environment.

Location and Distance

Distance is your first line of defense. Place the quarantine area as far from your main herd as practical. A minimum of 20 feet of separation is a good starting point. More distance is better when you have the space. The goal is to prevent direct contact and to reduce the chance of pathogen spread through aerosol droplets, dust, or runoff.

If you keep goats in a barn, use a separate building for quarantine if one is available. If you only have one barn, use a separate room or a sectioned off area with a solid wall between the quarantine space and the main herd. Do not use adjacent stalls that share a common wall if that wall has openings. A solid wall that reaches from floor to ceiling is acceptable. Chain link or cattle panels do not provide adequate separation because goats can touch noses through them and aerosols can pass through.

Outdoor quarantine pens should be positioned so that runoff from the quarantine pen does not flow toward your main herd's pasture or water source. If your property slopes, put the quarantine pen downhill from the main herd. This prevents contaminated water and manure from washing into the areas where your healthy goats live.

Consider prevailing wind direction when you choose a quarantine location. In most cases, you want the quarantine area downwind of the main herd. This reduces the chance that airborne pathogens or dust from the quarantine area reach your healthy animals. This matters most for respiratory diseases like pneumonia.

Fencing and Housing

The quarantine pen needs secure fencing that prevents escape. Goats are skilled escape artists, and a goat that gets out of quarantine is a biosecurity failure. Use the same quality of fencing you use for your main herd. Woven wire or electric netting works well for most setups. Make sure the fence is tall enough for your breed. Most goats can clear a 4 foot fence if they are motivated. A 5 foot fence is safer.

The housing inside the quarantine area should provide shelter from wind, rain, snow, and sun. A three sided shelter is adequate in most climates. It should face away from prevailing winds. The floor should be dry and well drained. Add deep bedding of straw or wood shavings. You will remove and replace this bedding between quarantine groups.

Space requirements for quarantined goats are the same as for any goat. A minimum of 20 square feet per goat inside a shelter and at least 100 square feet per goat in an outdoor pen is a reasonable guideline. More space reduces stress and makes cleaning easier. If you are quarantining a single goat, a pen of about 10 feet by 10 feet with an attached shelter is workable. For multiple goats, increase the size accordingly.

The quarantine pen should have a solid barrier between it and any neighboring pens. This prevents nose to nose contact. A solid sheet of plywood, metal roofing, or heavy plastic attached to the fence line works well. If you use a building, solid walls are best. Do not use a pen divider that goats can see through or touch through.

Feed and Water

Quarantined goats need their own feed and water containers. Never share buckets, troughs, or hay feeders between the quarantine area and the main herd. Feed and water containers in the quarantine area should be easy to clean and disinfect. Plastic or metal buckets work well. Avoid porous materials like unsealed wood.

Place feed and water containers inside the quarantine pen but position them so you can fill and clean them without entering the pen if possible. A pass through door or a hinged access panel in the fence makes this easier. This reduces the number of times you need to enter the quarantine area and decreases the chance of tracking contamination out.

Use the same quality feed you give your main herd. A sudden feed change adds stress to an already stressed animal. If you plan to change the ration, do it gradually over the quarantine period. Start with the feed the goat was eating at its source if you know what that was. Then slowly transition to your regular feed over 7 to 10 days.

Water is just as important. Provide clean, fresh water at all times. Goats drink more when they are stressed or sick, and dehydration makes any health problem worse. In cold weather, check water several times a day to make sure it is not frozen.

Handling and Working Facilities

You need a way to safely handle quarantined goats for examinations, treatments, and sample collection. A simple catch pen or crowding pen attached to the quarantine pen works well. A small chute or stanchion is helpful for holding a goat still while you take its temperature, draw blood, or give medication.

The handling area should be within the quarantine zone. Do not bring quarantined goats to your main handling facility. This is a common mistake. If you walk a quarantined goat through your main barn or through the same chute used by your healthy herd, you have defeated the purpose of quarantine.

If you do not have a separate handling area for quarantine, you can use a portable chute or stanchion that stays in the quarantine zone. Some producers use a simple gate system to corner a goat in the pen and hold it against a wall. A goat can be examined and treated in a corner if you have a second person to help. For solo work, a portable stanchion is worth the investment.

Ventilation and Airflow

If your quarantine facility is enclosed, ventilation is critical. Poor airflow in a closed barn concentrates respiratory pathogens and ammonia from urine and manure. This is a recipe for pneumonia and other respiratory disease. The quarantine area needs fresh air moving through it, but the air should not move from the quarantine area into the main herd's housing.

Natural ventilation is usually best. Open ridge vents, eave gaps, or windows on opposite sides of the building create cross ventilation. In warm weather, you can leave doors open. In cold weather, you still need airflow. A closed, stuffy shed is more dangerous for goats than a cold but well ventilated one.

If you use mechanical ventilation, such as a fan, make sure the airflow direction moves air away from the main herd. Exhaust fans should pull air out of the quarantine area and discharge it away from other buildings and pens.

Drainage and Waste Management

Plan for waste before you build. Manure and soiled bedding from the quarantine area must be handled carefully. The safest approach is to compost it on site for at least 6 months before spreading it on fields where your goats graze. Some pathogens survive for extended periods in manure. Direct contact with manure from quarantined animals is a transmission route you must eliminate.

The quarantine pen floor should slope slightly to allow liquids to drain away from the shelter. If you use a concrete floor, it should have a drain or be swept and washed easily. If you use dirt or gravel, you will need to remove the top layer of contaminated soil periodically and replace it with fresh material.

Keep a dedicated wheelbarrow, shovel, and manure fork in the quarantine area. Do not use the same tools for the main herd and the quarantine area. If you must use shared tools, clean and disinfect them thoroughly after each use in the quarantine area and before they are used anywhere else.

Step by Step Guide to Setting Up Your Quarantine Area

Follow these steps to establish a functional quarantine facility on your property.

Step 1: Choose the Location

Walk your property and identify a spot that is at least 20 feet from your main herd's housing and pasture. Consider wind direction, drainage, and accessibility. You need to be able to reach the quarantine area easily in bad weather and at night. If the location is too inconvenient, you will be tempted to skip daily checks, and that is where biosecurity breaks down.

Step 2: Build or Install the Pen

Set up the fencing and shelter. Make sure the fence is secure at ground level. Goats dig under fences, and new goats in an unfamiliar place will test the boundaries. Bury the bottom of the fence a few inches into the ground or use a hot wire along the bottom to discourage digging.

Install the shelter with dry bedding. Add a solid visual barrier between the quarantine pen and any adjacent pens. This reduces stress for the quarantined goat and prevents nose to nose contact.

Step 3: Set Up Feed and Water Stations

Place feed and water containers inside the pen. Position them for easy access from outside if possible. Fill them with the same feed and water your goats normally receive. Make sure the water container is heavy enough that a goat cannot tip it over. Goats are curious and will investigate their new surroundings by pushing and climbing on things.

Step 4: Stock the Quarantine Supply Kit

Put together a dedicated kit for the quarantine area. This kit should include:

A rectal thermometer and lubricant
Disposable gloves
Disinfectant appropriate for goat pathogens
A spray bottle for disinfectant
Paper towels
A flashlight
A notepad and pen for records
Basic first aid supplies for goats
A halter and lead rope
A hoof trimmer
A fecal sample collection kit or small bags for manure samples
Plastic bags for disposing of contaminated waste

Keep this kit in a sealed plastic bin inside or next to the quarantine area. Label it clearly. Do not use these supplies for the main herd.

Step 5: Establish the Traffic Pattern

Decide how you will move around your property to avoid cross contamination. The basic rule is to work with the main herd first and the quarantine animals last. Change your routine so that you never go from the quarantine area directly to the main herd without changing clothes and boots and washing your hands.

Some producers keep a pair of dedicated boots and a coverall in the quarantine area. You put these on when you enter the quarantine zone and take them off when you leave. Leave them in the quarantine area. This is a simple, effective system.

Step 6: Write Your Quarantine Protocol

Write down the rules before you need them. Include:

The length of the quarantine period for different situations
The tests you will run and when
The daily health check routine
The cleaning and disinfection schedule
The criteria for releasing a goat from quarantine
The criteria for calling a veterinarian

Post this protocol in the quarantine area and in your barn. Make sure everyone who works with your goats knows the rules and follows them.

The Quarantine Period: How Long Is Long Enough

The length of your quarantine period depends on the disease risks you face and the value of your herd. A 30 day minimum is the standard recommendation for most situations. This gives you time to observe the goat for signs of disease and to run at least one round of diagnostic tests.

Some diseases have longer incubation periods. CAE has an incubation period that can last months to years. Johne's disease can take years to show symptoms. A 30 day quarantine will not catch every possible disease. This is why testing is important and why some producers extend quarantine to 60 or even 90 days for high value animals.

Extend the quarantine period if:

The goat came from an auction, a sale barn, or a dealer. These goats have unknown health histories and high disease risk.
The goat came from a herd with known health problems.
The goat is showing any signs of illness.
You are adding the goat to a herd with valuable breeding stock or a closed herd that has been disease free.
You have had disease problems from new arrivals in the past.
The goat is pregnant and you want to minimize stress and disease risk during gestation.

A 60 day quarantine is a good default for high risk situations. It is long enough to run a second round of tests and to observe the goat through a full parasite treatment cycle. Some commercial producers use a 90 day quarantine for goats entering a CAE free herd.

During the quarantine period, you should also treat for internal parasites. A common protocol is to give a dewormer at arrival and then run a fecal egg count 10 to 14 days later to check for drug resistant parasites. The American Consortium for Small Ruminant Parasite Control recommends using fecal egg counts to guide treatment decisions rather than deworming blindly. If you do not have a microscope, work with your veterinarian or a diagnostic lab to run fecal egg counts.

Testing New Goats During Quarantine

Testing is a critical part of quarantine. You cannot see most diseases, and many infected goats show no signs. The tests you run depend on the diseases that are common in your area and the health status of your current herd.

Work with your veterinarian to develop a testing protocol. Common tests for goats include:

CAE testing. This is a blood test for caprine arthritis encephalitis. It is a serious, incurable disease that causes arthritis, pneumonia, and mastitis. If you run a CAE free herd, test all new arrivals and only allow negative goats in.
CL testing. Caseous lymphadenitis causes abscesses in lymph nodes and internal organs. It is highly contagious and difficult to eliminate once it enters a herd. Testing can identify infected animals.
Johne's disease testing. This is a chronic, fatal intestinal disease. Testing is complex and no single test is perfect. Work with your veterinarian to decide if testing is appropriate for your situation.
Brucellosis testing. This is a reportable disease in many states. Testing is regulated by state and federal authorities. Your veterinarian can advise you on the requirements in your area.
Fecal testing for internal parasites. A fecal egg count tells you what parasite burden the goat is carrying and whether the parasites are resistant to the dewormer you use.
Check for external parasites. Look for lice, mites, and ticks. Treat if you find any.

Test at arrival and again near the end of the quarantine period. A goat that tests negative at arrival could still be incubating a disease. A second test at day 30 or day 60 gives you more confidence that the goat is truly negative.

Some producers test for pregnancy and perform a breeding soundness exam during quarantine. This is a good use of the isolation period, especially if you are adding a buck or a doe for breeding purposes. The quarantine period gives the goat time to settle in before it has to perform.

Daily Health Checks During Quarantine

You should check quarantined goats at least twice a day. Morning and evening checks are ideal. The checks do not need to take long, but they need to be thorough and consistent.

Start by observing the goat from a distance before you enter the pen. Watch how it stands, moves, and interacts. A goat that is lying down and reluctant to rise may be sick. A goat that is isolated from other goats in the pen may be ill. A goat that is grinding its teeth may be in pain.

When you enter the pen, check:

Attitude and alertness. A healthy goat is curious and aware of its surroundings.
Appetite. Watch the goat eat. A goat that is not interested in feed is a concern.
Water intake. Check the water level in the bucket. A goat that is not drinking may be sick.
Manure. Look at the manure in the pen. Normal goat manure is in firm pellets. Diarrhea, mucus, blood, or very dry manure are all signs of trouble.
Urine. Check for signs of straining or blood. In bucks, watch for signs of urinary calculi, which is a blockage of the urinary tract.
Coughing or nasal discharge. A clear runny nose can be normal. Thick, colored discharge is a concern.
Eyes. Clear eyes with no discharge are normal. Sunken eyes can indicate dehydration.
Temperature. Take the rectal temperature of any goat that looks off. Normal goat temperature is 102 to 103 degrees Fahrenheit. A temperature over 103.5 degrees is a fever.
Body condition. Feel the goat's spine and ribs. A goat that is losing condition needs attention.
Hooves. Look for lameness or signs of foot rot or hoof abscess.
Skin and hair coat. Check for lumps, bumps, hair loss, or signs of external parasites.
Udder and testicles. Check for swelling, heat, or discharge.

If you notice any sign of illness, take the goat's temperature and note the findings in your record log. Contact your veterinarian if the goat has a fever, is not eating, has diarrhea, or shows any sign of a contagious disease.

Cleaning and Disinfecting the Quarantine Area

Cleaning and disinfection are not the same thing. Cleaning removes dirt and organic matter. Disinfection kills pathogens. You must clean before you disinfect because organic matter inactivates most disinfectants.

Clean the quarantine area daily. Remove manure and soiled bedding. Sweep or rake the floor. Keep the area dry. Wet, dirty conditions promote pathogen survival and parasite development.

Disinfect the quarantine area between groups of goats. The process is:

Remove the goat or goats from the pen.
Remove all bedding and manure. Dispose of it properly.
Scrub all surfaces with soap and water. Pay attention to corners, cracks, and any porous surfaces.
Rinse thoroughly.
Apply a disinfectant that is effective against the pathogens you are concerned about. Common choices include diluted bleach, accelerated hydrogen peroxide, or commercial livestock disinfectants. Follow the label directions for dilution and contact time.
Allow the pen to dry completely.
Leave the pen empty for as long as possible before the next goat arrives. A week is ideal. This allows time for any remaining pathogens to die.

Choose a disinfectant based on the diseases you are targeting. No single disinfectant kills everything. Bleach is cheap and effective against many pathogens but is inactivated by organic matter and is corrosive. Accelerated hydrogen peroxide products are effective and safer to use. Quaternary ammonium compounds are good general purpose disinfectants. Your veterinarian can recommend products for your specific situation.

Do not forget to disinfect feed and water containers, tools, and any equipment that touched the quarantined goats. The boots you wear in the quarantine area should be cleaned and disinfected or kept exclusively in that area.

Common Mistakes That Break Quarantine

Many quarantine failures come down to simple mistakes. Here are the most common ones and how to avoid them.

The first mistake is treating quarantine as a formality. Some producers keep a new goat separate for a few days and then turn it in with the herd because it looks healthy. This defeats the entire purpose. Many diseases are transmitted by animals that show no signs. The 30 day minimum exists for a reason.

The second mistake is sharing equipment. Using the same pitchfork, feed bucket, or hoof trimmers for quarantined and main herd goats is a direct transmission route. Keep dedicated tools in the quarantine area. If you must share, clean and disinfect between uses.

The third mistake is allowing nose to nose contact through a fence. Goats are social animals and will try to reach each other through any barrier. A standard wire fence does not stop this. You need a solid barrier between the quarantine pen and any neighboring pens.

The fourth mistake is walking through the main herd area after handling quarantined goats without changing clothes and boots. Your clothing and footwear can carry pathogens. This is why the quarantine area should be the last stop on your daily rounds.

The fifth mistake is placing the quarantine pen uphill or upwind of the main herd. Runoff and airborne particles can carry disease. Think about the flow of water and air on your property and position the quarantine area accordingly.

The sixth mistake is skipping testing. Visual observation alone is not enough. Many serious goat diseases are silent. Work with your veterinarian to run the appropriate tests during the quarantine period.

The seventh mistake is poor recordkeeping. If you do not write down your observations, test results, and treatments, you cannot track what happened or learn from past mistakes. A simple notebook is enough, but you must use it consistently.

The eighth mistake is releasing a goat from quarantine without a final health check. The last day of quarantine is not the day to get casual. Do a full health exam, run any final tests, and only then consider the goat ready to join the herd.

Introducing the Goat to the Main Herd

The end of the quarantine period does not mean you simply open the gate and let the new goat run in with the herd. Introduction is a stressful event that needs its own plan.

Before you introduce the new goat, make sure it is healthy. Do a final check of temperature, appetite, manure, and overall condition. Review your records to confirm that all test results are negative and any treatments are complete.

Choose a neutral area for introduction if possible. A pasture or pen that no goat has used recently is ideal. This reduces territorial aggression. If you cannot use a neutral area, introduce the goat during a time of day when the herd is calm, such as after feeding.

Introduce the new goat gradually. Some producers use a two step process. First, let the new goat share a fence line with the main herd for a few days so they can see and smell each other without direct contact. Then, introduce the goat into the main pen while you are present to supervise.

Expect some chasing and bunting. This is normal goat behavior. Goats establish a social hierarchy through pushing and shoving. The new goat will be at the bottom of the pecking order at first. This is stressful but usually resolves within a few days.

Watch the group closely for the first week after introduction. The stress of joining a new group can suppress the immune system and trigger disease in a goat that was healthy during quarantine. If the new goat shows signs of illness, remove it immediately and put it back in the quarantine area.

Provide extra feeding stations and space when you introduce a new goat. This reduces competition and gives the new goat a chance to eat without being bullied away from the feed. A goat that cannot access feed will lose condition quickly.

Biosecurity Beyond Quarantine

Quarantine is the most important biosecurity practice, but it is not the only one. A complete goat biosecurity program includes several other practices that work together with quarantine.

Control visitor access to your property. Any person who has been around other goats can carry pathogens on their boots, clothing, or hands. Post a sign asking visitors to check in before entering animal areas. Provide boot covers or a disinfectant footbath for visitors. Do not allow visitors to enter the goat pens unless it is necessary.

Clean and disinfect any equipment that comes onto your property from elsewhere. Trailers, portable panels, and show equipment can all carry disease. Clean and disinfect a borrowed trailer before you use it and again before you return it.

Maintain a closed herd when possible. The safest herd is one that never receives new animals. If you need to add genetics, consider using artificial insemination or embryo transfer instead of bringing in live animals. This eliminates the disease risk entirely.

Control wildlife and rodents. Birds, rats, mice, and stray animals can carry diseases between farms and between pens. Keep feed in sealed containers. Clean up spilled feed. Keep the area around your goat pens mowed and free of debris that attracts rodents.

Practice good manure management. Compost manure before spreading it on pasture. Many goat pathogens survive in manure for months. A proper compost pile that reaches high temperatures will kill most pathogens.

Keep your herd healthy with good nutrition and low stress management. A well fed goat with a low parasite load is more resistant to disease than a goat that is undernourished and stressed. Quarantine is a safety net, not a substitute for good husbandry.

Monitoring and Recordkeeping

Records are your early warning system. You cannot identify trends or spot problems if you do not have data. Keep a record for every goat that goes through quarantine.

At minimum, record:

The goat's identification (ear tag, tattoo, or name)
The date of arrival
The source of the goat and contact information for the seller
The reason for quarantine (new purchase, returning from show, sick animal)
The goat's age, breed, and sex
Any health history provided by the seller
Vaccination records if available
Test results and dates
Treatments given and dates
Daily observations
Feed and water intake
Temperature readings
The date quarantine ended and the goat was introduced to the herd

Use a simple notebook or a spreadsheet. Some producers use a whiteboard in the barn for daily observations and transfer the information to a permanent record weekly. The format does not matter as much as consistency. Record something every day.

Review your quarantine records regularly. Look for patterns. If goats from a particular source are frequently sick, stop buying from that source. If a particular treatment is not working, talk to your veterinarian about alternatives. If your quarantine period is consistently extending because of health issues, adjust your purchasing decisions.

When to Call a Veterinarian or Extension Agent

You do not need to call a veterinarian for every minor issue. Part of being a good goat producer is learning to handle routine health care yourself. But there are clear situations where professional help is needed.

Call a veterinarian if:

A quarantined goat has a fever over 103.5 degrees Fahrenheit
A goat is not eating or drinking for more than 24 hours
A goat has severe diarrhea, especially if there is blood
A goat is coughing repeatedly or has difficulty breathing
A goat has a swollen joint or is lame
A goat has a swollen udder or testicle
A goat is straining to urinate
A goat is unable to stand or is severely depressed
You suspect a contagious disease like CAE, CL, or Johne's disease
A goat dies unexpectedly

Your veterinarian can also help with testing protocols, parasite control programs, and vaccination schedules. Many producers work with their veterinarian to develop a herd health plan that covers the whole year. This is a worthwhile investment.

Extension agents from your state's land grant university are another valuable resource. They can provide information on local disease risks, parasite control, and management practices. They can also help you interpret test results and connect you with diagnostic laboratories. The American Consortium for Small Ruminant Parasite Control is a good source for parasite management information, and your extension agent can help you access it.

When you call a professional, have your records ready. Be prepared to describe the goat's age, source, arrival date, symptoms, temperature, and any treatments you have given. The more information you can provide, the better advice you will receive.

Designing for Different Farm Sizes

The size and complexity of your quarantine facility depends on the scale of your operation. A homesteader with three goats has different needs than a commercial operation with 200 does.

For a small farm with a few goats, a single quarantine pen is usually sufficient. You can build a simple pen with cattle panels or welded wire in a corner of your property. A small shelter or a three sided shed provides protection from the weather. The key is to keep the pen away from the main herd and to follow the same biosecurity rules.

For a medium size operation with 20 to 50 goats, you may want two quarantine pens. This allows you to quarantine multiple groups at the same time without mixing them. It also gives you a place to isolate a sick goat while a new arrival is in quarantine. If you only have one quarantine pen, you must completely clean and disinfect it between uses, which can delay the arrival of new animals.

For a large commercial operation, a dedicated quarantine building with multiple pens, a handling chute, and a separate entrance is worth the investment. The building should have its own feed storage, tool storage, and waste disposal system. You may want to designate one person as the quarantine manager who is responsible for all activities in that area.

Regardless of your farm size, the principles are the same. Separate the quarantine area from the main herd. Use dedicated equipment. Follow a written protocol. Keep records. The scale changes, but the system does not.

Common Goat Diseases That Quarantine Prevents

Understanding the diseases you are trying to prevent helps you design a better quarantine program. Here are the major goat diseases that quarantine and testing can keep out of your herd.

Caprine arthritis encephalitis (CAE) is a viral disease that causes chronic arthritis, pneumonia, mastitis, and encephalitis in kids. It is spread through colostrum, milk, and blood. Infected goats may show no signs for years. There is no cure. Testing and culling positive animals is the only way to maintain a CAE free herd.

Caseous lymphadenitis (CL) is a bacterial disease that causes abscesses in lymph nodes and internal organs. It is highly contagious and spreads through contact with pus from ruptured abscesses. The bacteria can survive for months in the environment. CL is difficult to eliminate once it enters a herd.

Johne's disease is a chronic bacterial infection of the intestine that causes progressive weight loss and diarrhea. It is fatal. The bacteria are shed in manure and contaminate the environment. Young goats are most susceptible to infection. There is no effective treatment.

Contagious ecthyma, also called soremouth or orf, is a viral disease that causes scabby lesions on the lips, mouth, and udder. It is highly contagious and can spread to humans. The virus survives for years in the environment.

Pneumonia can be caused by several bacteria and viruses. It spreads through respiratory droplets and close contact. Stress is a major trigger. New goats that are stressed from transport are at high risk.

Internal parasites, especially barber pole worms, are a constant threat. New goats can introduce drug resistant parasites to your pasture. Quarantine gives you time to treat parasites and confirm the treatment worked before the goat joins the herd.

Foot rot is a bacterial infection of the hoof that causes severe lameness. It spreads through contaminated soil and manure. Quarantine gives you time to inspect hooves and treat any infections before the goat walks on your pasture.

This list is not complete. Your local veterinarian and extension agent can tell you which diseases are most common in your area and which tests and vaccines are appropriate.

The Cost of Quarantine vs the Cost of Disease

Some producers resist building a quarantine facility because of the cost. A simple quarantine pen can be built for a few hundred dollars using materials you may already have on hand. Even a more elaborate facility is a small investment compared to the cost of a disease outbreak.

Consider what a disease outbreak costs. A single case of CAE in a valuable breeding doe means losing that animal's genetic contribution to your herd. If she has already infected other does through her milk, the cost multiplies. CL can take years to eliminate from a herd and requires constant vigilance with abscess management. Johne's disease can devastate a herd and contaminate your pasture for years.

The cost of treating sick animals includes veterinary bills, medications, and your time. The cost of lost production includes lower milk yield, reduced weight gain, and lost breeding opportunities. The cost of replacing animals is obvious. The cost of a reputation for selling sick goats can hurt your market for years.

Quarantine is cheap insurance. A basic facility, a thermometer, and a notebook cost very little. The time you spend checking quarantined goats twice a day is a small price to pay for protecting your herd.

Frequently Asked Questions

How long should I quarantine a new goat?

The minimum is 30 days. A 60 day quarantine is better for high risk animals, such as goats from auction or sale barns, or when you have valuable breeding stock. The quarantine period gives you time to observe the goat for signs of disease, run diagnostic tests, and treat parasites before the goat joins your main herd. Some producers extend quarantine to 90 days for goats entering a CAE free herd.

Can I quarantine a goat in the same barn as my main herd?

Yes, but only if the quarantine space has a solid wall that reaches from floor to ceiling and does not share air space with the main herd pens. Chain link, cattle panels, or open stall dividers do not provide adequate separation. Goats can touch noses through these barriers, and respiratory pathogens can travel through the air. A separate building is always the safest choice.

What tests should I run on a new goat during quarantine?

Work with your veterinarian to develop a testing protocol based on the diseases in your area and the health status of your herd. Common tests include CAE, CL, and Johne's disease blood tests, a fecal egg count for internal parasites, and a physical exam for external parasites and hoof problems. Test at arrival and again near the end of the quarantine period.

Do I need to quarantine a goat that was only gone for a day at a show?

Yes. A goat that leaves your property and returns has been exposed to other goats, shared equipment, and unfamiliar environments. Treat a returning goat the same way you treat a new purchase. Even a short absence carries disease risk. The quarantine period for a returning goat can be shorter if you know the goat's health history, but a minimum of 14 days is a reasonable starting point. Discuss your situation with your veterinarian.

What do I do if a quarantined goat gets sick?

Isolate the sick goat further if you have more than one goat in quarantine. Take its temperature and note all symptoms in your record log. Call your veterinarian if the goat has a fever, is not eating, has diarrhea, or shows signs of a contagious disease. Do not bring the goat to your main herd for treatment. Treat it in the quarantine area.

Can I use my quarantine pen for sick goats from my main herd?

Yes, a goat isolation pen can serve both purposes. A goat that is sick and a new arrival in quarantine should not be housed together unless you know they have the same health status. If you use the quarantine pen for a sick goat from your main herd, you must thoroughly clean and disinfect the pen before you use it for a new arrival.

How do I clean and disinfect the quarantine pen between goats?

Remove all bedding and manure, scrub all surfaces with soap and water, rinse, apply a disinfectant that is effective against the pathogens you are concerned about, and allow the pen to dry completely. Leave the pen empty for as long as possible before the next goat arrives. A week is ideal. Do not forget to disinfect feed and water containers and any tools used in the pen.

What should I feed a goat during quarantine?

Feed the same quality feed you give your main herd. If you plan to change the ration, do it gradually over 7 to 10 days. Start with the feed the goat was eating at its source if you know what that was. Provide clean, fresh water at all times. A new goat is under stress, and a sudden feed change adds to that stress.
