Goat Barn Odor Control: Ammonia and Ventilation Solutions

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

Key Takeaways

• Elevated ammonia levels (above 15-25 ppm at goat nose level) directly irritate respiratory mucous membranes, forming caustic ammonium hydroxide, which compromises cilia function and increases susceptibility to pneumonia, a leading cause of mortality and production loss in goats.
• Effective ventilation is paramount, requiring continuous air exchange to remove ammonia and moisture; natural ventilation relies on wind pressure and stack effect via adjustable inlets and outlets, while mechanical ventilation uses exhaust fans to achieve air exchange rates of 1-2 minutes in summer and 5-10 minutes in winter.
• Bedding management is critical, with deep bedding systems (6-8 inches initial layer, adding fresh material regularly) or spot cleaning (daily removal of wet material) being effective, provided absorbent materials like straw or wood shavings are used to maintain a dry surface and prevent urea breakdown into ammonia.
• Objective ammonia measurement using colorimetric gas detection tubes or electronic sensors is essential, as olfactory fatigue renders subjective smell unreliable; readings should be taken at goat nose level (12-24 inches above floor) in the morning when levels are highest.
• Overcrowding (exceeding recommended space allowances of 15-20 sq ft/adult doe) significantly exacerbates ammonia issues by increasing urine and manure load, while proper water management (ensuring access to clean, dilute urine) and feed adjustments (avoiding excessive protein) are crucial for mitigating ammonia production.

If your goat barn smells strongly of ammonia, you already know the problem is more than just unpleasant. That sharp, burning smell means urine is breaking down into ammonia gas, and your goats are breathing it in every minute they spend inside. High ammonia levels irritate the respiratory tract, weaken the immune system, and make your herd more vulnerable to pneumonia and other diseases. This guide is for goat owners, small ruminant producers, and farm managers who want to fix barn odor at the source. You will learn how to measure ammonia, design a ventilation system that works for your climate, choose the right bedding and manure management routine, and know when the problem requires a veterinarian or extension agent.

At a Glance

The single most important takeaway is this: if you can smell ammonia, your goats are already breathing harmful levels of it. Fix the airflow and the moisture, and the smell will follow.

Understanding Ammonia in the Goat Barn

Ammonia gas comes from the breakdown of urea, which is the main nitrogen waste product in goat urine. When urine mixes with moisture and bacteria, enzymes convert the urea into ammonia and carbon dioxide. This process happens faster in warm, damp conditions and when bedding is allowed to stay wet for long periods.

The chemical formula is simple. Urea, which has the formula CO(NH2)2, reacts with water and the enzyme urease to produce ammonia gas (NH3) and carbon dioxide (CO2). The ammonia then dissolves in the moisture on your goats' respiratory mucous membranes and forms ammonium hydroxide, which is caustic. That is why your eyes water and your throat burns when you walk into a poorly ventilated goat barn.

Ammonia is lighter than air, so it tends to rise. However, in a barn with poor air movement, it can accumulate at any level, especially near the floor where your goats sleep. Young kids are particularly at risk because they are closer to the ground and their airways are smaller and more easily damaged.

Several factors determine how much ammonia builds up in a goat barn:

• Herd density, or how many goats are housed per square foot of floor space
• Bedding type and how often it is changed
• Floor type, whether solid concrete, dirt, slatted, or deeply bedded
• Ventilation rate, or how many times per hour the barn air is exchanged
• Temperature and humidity inside the barn
• Urine volume, which increases when goats drink more water or eat high-protein feeds

The interaction between these factors is why two barns with the same number of goats can smell very differently. A barn with excellent airflow and a diligent bedding routine will have minimal odor even in summer. A barn with poor airflow and infrequent cleaning will smell strongly even with only a few goats inside.

Why Goat Barn Odor Control Matters for Herd Health

Ammonia is not just a nuisance odor. It is a direct threat to goat health, and the effects are cumulative. Chronic low-level exposure is more damaging than a single high exposure because the respiratory tract never gets a chance to recover.

When goats inhale ammonia, the gas dissolves in the moisture lining their nasal passages, trachea, and lungs. This creates ammonium hydroxide, which irritates and inflames the mucous membranes. The body responds by producing more mucus, which traps bacteria and makes the airways narrower. The cilia, which are tiny hair-like structures that sweep mucus and debris out of the lungs, slow down and become less effective.

The result is a goat that is more susceptible to respiratory infections. Pneumonia is one of the leading causes of death and production loss in goats, and poor air quality is a major contributing factor. The USDA APHIS Goat Health resources highlight respiratory disease as a significant concern for goat producers. When you combine high ammonia levels with other stressors like weaning, transport, weather changes, or parasite loads, the risk of a pneumonia outbreak increases dramatically.

Ammonia also affects the eyes. Goats exposed to high ammonia levels often develop red, watery eyes, conjunctivitis, and corneal ulcers. The irritation makes them rub their eyes against fences, feeders, and other surfaces, which can introduce bacteria and make the problem worse.

Beyond respiratory and eye problems, chronic ammonia exposure causes general stress. Stressed goats have higher cortisol levels, which suppress immune function and reduce feed efficiency. You may notice reduced weight gain, lower milk production, and poorer reproductive performance. In severe cases, high ammonia levels can cause neurological signs, appetite loss, and severe respiratory distress.

The Occupational Safety and Health Administration, which is a US regulatory body, sets a permissible exposure limit of 50 parts per million (ppm) for workers over an 8 hour shift. However, goats are more sensitive than humans in many ways because they are smaller and have faster metabolic rates. A general rule for goat housing is to keep ammonia below 15 to 25 ppm at goat nose level. Many producers aim for below 10 ppm to be safe.

How to Measure Ammonia Levels in Your Goat Barn

You cannot manage what you do not measure. Your nose is a useful early warning system, but it adapts quickly. After a few minutes inside a barn, you stop noticing the smell, even when ammonia levels are dangerously high. You need objective measurements.

Several tools are available for measuring ammonia in farm buildings:

Colorimetric gas detection tubes. These are glass tubes filled with a chemical that changes color when exposed to ammonia. You break off the ends, attach the tube to a hand pump, and draw a measured volume of air through it. The length of the color change indicates the ammonia concentration. These tubes are accurate and relatively inexpensive. They are single use, so you need to buy them in packs.

Electronic ammonia sensors. Portable gas detectors with electrochemical ammonia sensors give real time readings on a digital display. They are more expensive than detection tubes but can be used repeatedly. Look for a sensor with a range of 0 to 100 ppm and an accuracy of plus or minus 5 ppm. Calibrate the sensor regularly according to the manufacturer instructions.

Passive diffusion tubes. These are small tubes that you leave in the barn for a set period, usually 8 to 24 hours. The ammonia in the air diffuses into the tube and reacts with a chemical. You send the tube to a laboratory for analysis. This method gives an average concentration over time, which is useful for assessing chronic exposure.

pH test strips for bedding. While not a direct measurement of airborne ammonia, testing the pH of your bedding can indicate when it is starting to break down. Fresh urine has a pH around 6 to 7. As urea breaks down into ammonia, the pH rises above 8. If your bedding pH is consistently above 8, ammonia is being released into the air.

For most goat producers, a simple and affordable approach is to use colorimetric gas detection tubes or a portable electronic sensor. Measure at goat nose level, which is typically 12 to 24 inches above the floor, in several locations around the barn. Measure in the morning before you open the doors, because this is when ammonia levels are highest after a night of closed ventilation.

Also measure at your own standing height to compare. If the ammonia level at your nose is 10 ppm but at goat nose level it is 30 ppm, your goats are being exposed to dangerous levels even though you may not notice it.

Ventilation: The Foundation of Goat Barn Odor Control

Ventilation is the single most important factor in controlling ammonia and moisture in a goat barn. Without adequate air exchange, no amount of bedding or cleaning will keep the barn fresh. Ventilation serves three purposes: it removes ammonia and other gases, it removes moisture from respiration and urine, and it brings in fresh oxygen.

A well designed ventilation system moves air through the barn continuously, even in winter. The common misconception is that closing the barn up tight in cold weather keeps goats warm and healthy. The opposite is true. A closed barn traps moisture and ammonia, which leads to respiratory disease. Goats are hardy animals that tolerate cold well as long as they are dry and protected from drafts. They do not tolerate damp, stale air.

Natural Ventilation Principles

Natural ventilation relies on two forces: wind pressure and the stack effect. The stack effect is the tendency of warm, moist air to rise and escape through openings in the roof, drawing cooler fresh air in through openings at the sides. This works best when there is a temperature difference between inside and outside air, which is why natural ventilation is more effective in winter than in summer.

For natural ventilation to work, you need both inlet and outlet openings. Inlets should be low on the walls, ideally at goat height or below, and outlets should be at the ridge of the roof. The total inlet area should be roughly equal to the total outlet area. As a rule of thumb, provide at least 1 square foot of inlet and outlet opening per 500 pounds of goat weight housed in the barn.

Common inlet options include:

• Hinged windows or doors that can be opened partially
• Adjustable wall vents with sliding covers
• Open eaves or soffit vents
• Curtains or tarps that can be rolled up

Common outlet options include:

• Ridge vents running the full length of the roof
• Cupolas with open louvers
• Gable end vents placed high on the walls
• Chimney vents

The key is adjustability. You need to be able to reduce airflow during severe winter storms without closing the barn completely. A barn with permanently open ridge vents and adjustable side curtains gives you the most control.

Mechanical Ventilation

In some situations, natural ventilation is not enough. Barns in hot, humid climates, barns with high goat densities, and barns with poor natural airflow may need mechanical ventilation. Mechanical ventilation uses fans to force air movement.

There are two main types:

Exhaust fans. These fans pull air out of the barn, creating a slight negative pressure that draws fresh air in through inlets. Exhaust fans are the most common type in livestock barns. Place them high on the walls or in the roof, and make sure the inlets are positioned so that fresh air flows across the goat living area.

Circulation fans. These fans do not bring in fresh air. They simply move existing air around the barn. Circulation fans are useful for keeping air moving in summer and for preventing stagnant pockets, but they do not remove ammonia or moisture. You need exhaust fans or natural ventilation for air exchange.

For mechanical ventilation, a general guideline is to provide enough fan capacity to exchange the barn air every 1 to 2 minutes in summer and every 5 to 10 minutes in winter. Calculate the volume of your barn by multiplying length times width times average height. Divide this by the desired exchange time to get the required fan capacity in cubic feet per minute (CFM).

For example, a barn that is 40 feet long, 20 feet wide, and 10 feet high has a volume of 8,000 cubic feet. To exchange the air every 2 minutes, you need 4,000 CFM of fan capacity. To exchange every 10 minutes in winter, you need 800 CFM.

Managing Drafts in Winter

The challenge with winter ventilation is bringing in cold air without creating drafts at goat level. Cold drafts stress goats and can cause respiratory problems, especially in kids.

The solution is to bring air in above goat level and let it mix with warmer barn air before it falls to the floor. Install inlets high on the walls, near the ceiling, and direct them upward or horizontally across the ceiling. The incoming cold air mixes with the warm air trapped near the roof, so it reaches the goats at a more moderate temperature.

If you use a positive pressure ventilation system, which pushes air into the barn, you can distribute fresh air through perforated ducts that run the length of the barn. This is the most effective way to provide draft free ventilation in cold climates. The ducts are typically 12 to 24 inches in diameter, made of polyethylene or similar material, and hung from the ceiling. Small holes along the length of the duct distribute the air evenly.

Minimum Ventilation Rates

Even in the coldest weather, you must maintain a minimum ventilation rate to control moisture and ammonia. A general minimum for goats is 30 to 60 CFM per adult goat, depending on the climate and barn design. This is enough to remove the moisture produced by respiration and the ammonia produced by urine without causing excessive heat loss.

To calculate your minimum winter ventilation rate, multiply the number of goats by the per goat rate. For 50 goats at 40 CFM each, you need 2,000 CFM of minimum winter ventilation.

Monitoring humidity is a good way to check whether your ventilation is adequate. Relative humidity inside a goat barn should stay between 50 and 75 percent. If humidity is consistently above 75 percent, you need more ventilation. If it is below 50 percent in winter, you may be over-ventilating and wasting heat.

Bedding Strategies to Reduce Goat Barn Smell

Bedding is your second line of defense against ammonia. Good bedding absorbs urine, keeps the floor dry, and provides a comfortable surface for goats to lie on. Wet bedding is the main source of ammonia production, so keeping bedding dry is the most direct way to reduce odor.

Choosing the Right Bedding Material

Several materials work well for goat bedding. The best choice depends on what is available and affordable in your area.

Wheat straw. Straw is the most common goat bedding. It is absorbent, relatively inexpensive, and provides good insulation. Wheat straw is preferable to barley or oat straw because it is more absorbent and less likely to mold. Straw works best in a deep bedding system where you add fresh layers on top of old ones.

Wood shavings. Pine shavings are highly absorbent and control odor well. They are more expensive than straw but last longer. Avoid cedar shavings, which can cause respiratory irritation in some animals. Wood shavings work well in a spot cleaning system where you remove wet areas daily.

Sawdust. Sawdust is very absorbent but can be dusty. It is best used as a base layer under straw or shavings. Fine sawdust can pack down and become less effective over time.

Chopped cardboard. Shredded or chopped cardboard is a good absorbent bedding that is often available cheaply from recycling centers. It controls odor well but can be dusty and may need frequent replacement.

Sand. Sand drains well and does not harbor bacteria, but it is heavy, hard on equipment, and can cause digestive problems if goats eat it. It is more common in dairy cattle barns than goat barns.

Hemp bedding. Hemp is highly absorbent, controls odor effectively, and composts well. It is more expensive than straw but may be worth the cost for small herds.

Paper bedding. Processed paper bedding is absorbent and dust free but can be expensive. It works well for kidding pens and sick pens.

Deep Bedding System

The deep bedding system, also called deep litter, involves adding fresh bedding on top of old bedding without removing the soiled material. The bedding builds up over weeks or months, and the bottom layers compost slowly, generating some heat. This system works well in cold climates where the heat of composting helps keep the barn warm.

To manage a deep bedding system:

1. Start with a clean, dry floor.
2. Add a base layer of 6 to 8 inches of absorbent bedding.
3. Add fresh bedding daily or every other day, focusing on areas where goats urinate and lie.
4. Stir or turn the bedding occasionally to promote drying and composting.
5. Remove the entire pack when it reaches 12 to 18 inches deep, or when it becomes wet and compacted.

The deep bedding system works best with a carbon rich material like straw or shavings. The key is to add enough fresh bedding to keep the surface dry. If the surface stays wet, the pack will not compost properly and will produce ammonia.

Spot Cleaning System

The spot cleaning system involves removing wet and soiled bedding daily and replacing it with fresh material. This is more labor intensive than deep bedding but keeps the barn drier and reduces ammonia more effectively.

To manage a spot cleaning system:

1. Start with a 4 to 6 inch base layer of bedding.
2. Each morning, remove all visibly wet and manure soiled bedding.
3. Replace with fresh bedding in the removed areas.
4. Once per week, strip the entire barn and start fresh.

Spot cleaning works best with highly absorbent bedding like wood shavings or hemp. It is the preferred system for kidding pens and for barns with limited space.

The Role of Flooring

Your floor type has a huge impact on how well your bedding works. A rough concrete floor holds bedding in place but absorbs urine if it is not sealed. A sealed, smooth concrete floor is easier to clean but can be slippery and cold. Dirt floors are warm and absorbent but difficult to clean thoroughly and can harbor parasites.

For concrete floors, apply a concrete sealer to prevent urine from soaking into the porous surface. This makes cleaning easier and reduces odor. Slope the floor slightly, about 1/4 inch per foot, toward a drain or doorway so that liquids run off instead of pooling.

For dirt floors, consider installing a layer of compacted gravel topped with sand or fines. This improves drainage and makes the floor easier to clean than bare dirt.

Slatted or perforated floors allow urine and manure to fall through into a pit below. This is common in commercial operations but is expensive to install and can be hard on goat feet. If you use slatted floors, the pit below must be ventilated to prevent ammonia from rising back into the barn.

Manure Management and Cleaning Routines

Regular cleaning is essential for goat barn odor control. Ventilation and bedding can only do so much if manure and urine are allowed to accumulate. A consistent cleaning routine prevents ammonia from building up in the first place.

Daily Cleaning Tasks

At minimum, you should do the following every day:

1. Remove all wet bedding and manure from the goat living areas.
2. Scrape or sweep solid floors to remove urine and manure.
3. Add fresh bedding to replace what you removed.
4. Empty and clean water troughs. Spilled water adds moisture to the barn and accelerates ammonia production.
5. Check and clean feed areas. Wet, moldy feed contributes to odors and attracts flies.

The best time to clean is in the morning, before the day heats up. Warm temperatures accelerate ammonia production, so removing manure and wet bedding early reduces the amount of ammonia released during the day.

Weekly Cleaning Tasks

Once per week, do a more thorough cleaning:

1. Remove all bedding from the barn, or at least from high traffic areas.
2. Scrub or pressure wash solid floors with a disinfectant cleaner.
3. Allow the floor to dry completely before adding fresh bedding.
4. Clean and disinfect feeders, water troughs, and mineral blocks.
5. Check and clean ventilation inlets and outlets to ensure they are not blocked.

Manure Storage and Composting

Where you store manure matters. A pile of manure and wet bedding right next to the barn will continue to produce ammonia and odor, and the smell will drift back into the barn. Store manure at least 50 feet from the barn, and ideally further if you have the space.

Composting manure properly reduces odor and produces a valuable soil amendment. The key to composting is achieving the right balance of carbon and nitrogen, moisture, and oxygen.

• Carbon comes from bedding material like straw, shavings, or cardboard.
• Nitrogen comes from manure and urine.
• The ideal carbon to nitrogen ratio is about 25 to 30 parts carbon to 1 part nitrogen.
• Moisture should be 50 to 60 percent, like a wrung out sponge.
• Oxygen is provided by turning the pile regularly.

A well managed compost pile reaches internal temperatures of 130 to 150 degrees Fahrenheit, which kills most pathogens and fly larvae. Turn the pile every 3 to 7 days to maintain oxygen levels. The composting process takes 3 to 6 months, depending on the season and how often you turn the pile.

Fly Control

Flies are not just a nuisance. They are attracted to manure and moisture, and they can transmit diseases between animals. A clean barn is the first line of defense against flies. Remove manure daily, keep bedding dry, and do not let feed accumulate.

For additional fly control, consider:

• Fly predators, which are parasitic wasps that lay eggs in fly pupae
• Fly traps placed around the barn perimeter
• Insecticide baits placed in areas where goats cannot reach them
• Feed additives that reduce fly larvae in manure

Water Management and Urine Dilution

Goats that are well hydrated produce more urine, which might seem like it would make odor worse. In fact, the opposite is true. Well hydrated goats produce more dilute urine, which breaks down into ammonia more slowly than concentrated urine. Concentrated urine is a bigger odor problem than dilute urine.

Ensure your goats always have access to clean, fresh water. In winter, provide heated waterers to prevent freezing. A goat that does not drink enough in winter will produce concentrated urine that creates more ammonia.

Also check your feed program. High protein feeds increase urea excretion, which increases ammonia production. Feed goats according to their production stage and avoid overfeeding protein. If you are feeding a high protein ration and notice increased ammonia in the barn, talk to your extension agent about adjusting the ration.

Herd Density and Space Requirements

Overcrowding is a major cause of poor air quality in goat barns. More goats in a confined space means more urine, more manure, more moisture, and more ammonia. It also means more stress, which makes goats more susceptible to respiratory disease.

The recommended space allowances for goats depend on their size and the type of housing:

• Adult does in a loafing barn: 15 to 20 square feet per goat
• Adult bucks: 30 to 40 square feet per goat
• Kids: 5 to 10 square feet per goat
• Kidding pens: 20 to 30 square feet per doe with kids
• Sick pens: 30 to 40 square feet per goat

These are minimums. More space is always better, especially in hot weather or when goats are housed indoors for extended periods.

If your barn is overcrowded, you have three options: reduce the number of goats, expand the barn, or increase ventilation. The quickest fix is often to increase ventilation to compensate for the higher moisture and ammonia load. But ventilation cannot fully compensate for overcrowding, so plan to address the space issue in the long term.

Seasonal Adjustments for Goat Barn Odor Control

Ammonia production varies with the seasons, and your management should adjust accordingly.

Summer

In summer, heat is the main challenge. High temperatures accelerate ammonia production, and goats naturally spend more time in the barn to escape the heat and flies. Ventilation is critical.

• Open all doors, windows, and vents fully.
• Use circulation fans to keep air moving across the goat resting areas.
• Provide shade over outdoor loafing areas to encourage goats to spend time outside.
• Clean the barn more frequently, as heat accelerates ammonia production.
• Consider misting systems or evaporative cooling in extreme heat, but be careful not to increase humidity excessively.

Winter

In winter, the challenge is balancing ventilation with heat retention. Ammonia levels are typically highest in winter because barns are closed up to keep the goats warm.

• Maintain minimum ventilation even in the coldest weather.
• Use high inlets to bring cold air in above goat level and let it mix with warm air.
• Increase bedding depth to absorb more urine and provide insulation.
• Clean wet bedding more frequently, as moisture does not evaporate as quickly in cold conditions.
• Use heated waterers to encourage drinking and dilute urine.

Spring and Fall

The shoulder seasons often have the most variable weather. Watch the forecast and adjust ventilation accordingly.

• Open up the barn on mild days to air it out.
• Watch for sudden temperature drops that may prompt you to close vents.
• Deep clean the barn between seasons to remove accumulated bedding and manure.

Common Mistakes in Goat Barn Odor Control

Many goat owners make the same mistakes when trying to control barn odor. Recognizing these mistakes can save you time, money, and frustration.

Mistake 1: Closing the barn up tight in winter. This is the most common and most damaging mistake. A closed barn traps moisture and ammonia, creating a breeding ground for respiratory disease. Goats are cold hardy and will be healthier in a cold, dry barn than a warm, damp one.

Mistake 2: Relying on your nose to detect ammonia. Your sense of smell adapts quickly. After 10 minutes in a barn, you will not notice the ammonia even if levels are dangerously high. Use a test kit or sensor for objective measurement.

Mistake 3: Using too little bedding. Skimping on bedding saves money in the short term but costs more in the long term through increased respiratory disease and more frequent barn cleaning. Use enough bedding to keep the floor surface dry at all times.

Mistake 4: Adding bedding on top of wet bedding. This creates a wet pack that produces ammonia continuously. You must remove wet bedding before adding fresh bedding. It is better to remove and replace than to simply cover up.

Mistake 5: Ignoring the floor. A porous concrete floor absorbs urine and releases ammonia for months. Seal concrete floors and slope them for drainage.

Mistake 6: Overcrowding the barn. More goats in less space means more ammonia. Respect minimum space allowances and expand or reduce the herd as needed.

Mistake 7: Ventilating only when it is hot. Ammonia is often worse in winter than summer because barns are closed. Maintain minimum ventilation year round.

Mistake 8: Using the wrong bedding material. Some materials, like cedar shavings, can cause respiratory irritation. Others, like fine sawdust, become dusty and pack down. Choose a bedding that is absorbent, low dust, and appropriate for your cleaning system.

Mistake 9: Storing manure next to the barn. A manure pile near the barn creates odor and attracts flies. Store manure at least 50 feet away and compost it properly.

Mistake 10: Waiting for goats to show signs of illness. By the time goats show respiratory signs, the damage is already done. Monitor ammonia levels proactively and act before problems develop.

Decision Thresholds: When to Act

Knowing when to take action is as important as knowing what to do. Use these thresholds to guide your decisions.

Ammonia levels:

• 0 to 10 ppm: Normal, acceptable range. Continue current management.
• 10 to 15 ppm: Action threshold. Increase ventilation and cleaning frequency. Check bedding moisture.
• 15 to 25 ppm: High. Take immediate action. Deep clean the barn, increase ventilation, and address any bedding or drainage issues.
• Above 25 ppm: Dangerous. Remove goats from the barn if possible, or open all doors and windows. Call your veterinarian if goats show any respiratory signs.

Relative humidity:

• Below 50 percent: Acceptable, though very low humidity may indicate over-ventilation in winter.
• 50 to 75 percent: Optimal range.
• Above 75 percent: Too humid. Increase ventilation and reduce moisture sources like spills and wet bedding.

Bedding moisture:

• Bedding should be dry on the surface. If you press your hand into the bedding and it feels damp, add fresh bedding or remove wet material.
• If bedding is wet below the surface but dry on top, you may be adding bedding too frequently without removing the wet layer. This creates a wet pack that produces ammonia.

Goat health signs:

• Coughing, sneezing, nasal discharge, or eye irritation in multiple goats: Check ammonia levels immediately, even if you cannot smell it.
• Reduced feed intake or milk production: Poor air quality may be a contributing factor.
• Labored breathing or open mouth breathing: This is an emergency. Move goats to fresh air and call a veterinarian.

Monitoring and Recordkeeping

Keeping records of your barn environment and goat health helps you identify trends and catch problems early. You do not need complex equipment or software. A simple notebook or spreadsheet is sufficient.

Track the following weekly:

• Ammonia levels at goat nose level in multiple locations
• Temperature and humidity inside and outside the barn
• Bedding type and depth
• Cleaning frequency
• Number of goats housed
• Any goat health issues, especially respiratory signs
• Ventilation settings and any changes made

This recordkeeping serves several purposes. It helps you identify patterns, such as ammonia spikes during certain weather conditions or after changes in feed. It helps you evaluate the effectiveness of management changes. And it provides valuable information for your veterinarian if health problems develop.

When to Call a Veterinarian or Extension Agent

Most goat barn odor problems can be solved with management changes. However, there are times when professional help is needed.

Call a veterinarian if:

• Any goat shows signs of respiratory distress, including labored breathing, open mouth breathing, or blue tinged mucous membranes
• Multiple goats develop coughing, nasal discharge, or eye irritation
• Goats are not eating or are losing weight despite good feed and management
• You suspect pneumonia or another infectious disease
• Kids are failing to thrive or have chronic respiratory problems

Call your local extension agent or agricultural advisor if:

• You need help calculating ventilation requirements for a new or remodeled barn
• You are designing a new barn and want to incorporate proper ventilation from the start
• You are considering a major change in housing, such as switching from a spot cleaning to a deep bedding system
• You need help evaluating your feed program for protein levels that may be contributing to ammonia production
• You want to test your water quality, which can affect urine output and ammonia levels

Your extension agent can also help you find local resources, such as soil testing for manure application and workshops on barn design and ventilation.

Frequently Asked Questions

How much ammonia is dangerous for goats?

Ammonia levels above 15 to 25 ppm at goat nose level are considered dangerous and require immediate action. Even levels below that can be harmful with chronic exposure. If you can smell ammonia, it is already above a safe level for goats. Use a test kit or sensor for objective measurement, and keep levels below 10 ppm if possible.

Can I use lime to control ammonia in my goat barn?

Hydrated lime can be spread on the floor before adding bedding to help control odor and dry the floor. However, lime is caustic and can cause skin and respiratory irritation if it becomes dusty. Use it sparingly and only on a dry floor before adding fresh bedding. Do not use lime directly on bedding where goats lie, because it can burn their skin and eyes. Agricultural lime is less caustic but also less effective at controlling odor.

Why does my goat barn smell worse in winter than summer?

Winter barns are typically closed up to retain heat, which traps moisture and ammonia. Cold air holds less moisture, so condensation forms on walls and ceilings, adding to the moisture problem. The solution is to maintain minimum ventilation even in winter, using high inlets to bring cold air in above goat level without creating drafts.

Will a bigger barn solve my odor problem?

A bigger barn with the same number of goats will reduce ammonia because there is more air volume to dilute the gas and more space per goat. However, a bigger barn with poor ventilation will still have odor problems. Ventilation and cleaning are more important than barn size. If you are expanding, design the ventilation system properly from the start.

How often should I clean my goat barn to control odor?

At minimum, remove wet bedding and manure daily. Do a thorough cleaning, including stripping all bedding and disinfecting the floor, at least weekly. In hot weather or with high goat density, you may need to clean more frequently. The goal is to keep the floor surface dry at all times.

What is the best bedding for controlling goat barn smell?

Wood shavings and hemp are the most effective at absorbing urine and controlling ammonia. Wheat straw is a good economical choice, especially in a deep bedding system. Avoid cedar shavings, which can cause respiratory irritation. The best bedding is one that you can keep dry and replace regularly.

Can I use a fan to control ammonia in my goat barn?

A circulation fan alone will not remove ammonia. You need exhaust fans or natural ventilation to bring in fresh air and remove stale air. Circulation fans can help prevent stagnant pockets of air and keep goats cool in summer, but they must be combined with proper air exchange.

My goats have watery eyes and are coughing. Is this from ammonia?

These are classic signs of ammonia exposure and respiratory irritation. Check ammonia levels immediately, even if you cannot smell it. Move goats to fresh air if levels are high. If signs persist after improving ventilation and cleaning, call a veterinarian, because the goats may have developed a secondary respiratory infection.
