Ventilation plays a vital role in swine production, influencing both animal welfare and operational efficiency. One of the most effective and widely used ventilation methods in modern pig barns is cross ventilation—a system that enhances air quality while maintaining comfortable temperatures for pigs at all production stages.
How Cross Ventilation Works
Cross ventilation relies on a sidewall-to-sidewall airflow system, which efficiently removes stale air and introduces fresh air, creating a more consistent and healthy environment for livestock. The process works as follows:
-
Air enters the barn through inlets located along one sidewall.
-
Air moves across the width of the barn, distributing evenly through the space.
-
Fans positioned on the opposite sidewall extract stale air, preventing buildup of harmful gases and excess moisture.
Key Benefits of Cross Ventilation
-
Improved Animal Welfare – By
reducing ammonia, CO₂, and humidity levels, cross ventilation helps
maintain optimal air quality, which decreases the risk of respiratory
issues in pigs.
-
Heat Stress Reduction –
Effective airflow regulation minimizes temperature spikes, ensuring pigs
stay within their thermal comfort zones, leading to better feed
conversion and growth rates.
-
Energy Efficiency – Compared to
traditional ventilation systems, cross ventilation optimizes airflow
distribution, lowering energy consumption and operational costs.
-
Ideal for Narrow Barns – This system is especially beneficial for facilities where tunnel ventilation is not feasible, such as narrower swine barns or regions with challenging wind patterns.
Design Considerations for Effective Cross Ventilation
To maximize the effectiveness of cross ventilation, barns should be properly oriented to leverage prevailing winds. Other key design factors include:
-
Airflow perpendicular to the feed lane and parallel to stalls for uniform ventilation.
-
Room depth should not exceed five times the room height to maintain proper air circulation.
-
Automated control systems, like PigTek’s PigCentral®, help monitor and adjust ventilation conditions in real time, ensuring optimal performance and animal comfort.
How PigTek Helps Producers Implement Cross Ventilation
At PigTek, we specialize in custom ventilation
solutions tailored to individual barn layouts and production needs. Our
expert team works closely with producers to design and implement cross
ventilation systems that enhance air quality, support animal health, and
improve energy efficiency—while ensuring a strong return on investment.
A critical part of this approach is the PigCentral® Control,
a flexible and intuitive barn management system that allows you to
monitor and adjust ventilation, feed delivery, and more from a single
dashboard. Built in the U.S. and fully customizable, PigCentral® offers
real-time remote access, powerful alarm management, and user-specific
security levels—empowering producers to take full control of their
environment with confidence and ease.
Conclusion
Cross ventilation is a proven and effective solution for optimizing swine barn environments, balancing animal welfare, energy efficiency, and barn performance. As swine production continues to evolve, advanced ventilation technology will play a crucial role in shaping the future of sustainable, high-efficiency barns.

As temperatures rise, now is the perfect time to
ensure your ventilation and equipment are optimized for the season.
PigTek recommends these eight essential maintenance tips to keep your
barn running efficiently:
- Inspect and Clean Ventilation Systems
- Ensure fans, inlets, and ducting are free from dust and debris. Test
controls and sensors to maintain proper airflow and temperature
regulation.
- Check Watering Systems for Leaks and Blockages
- Flush water lines, inspect nipples and valves, and confirm consistent water pressure to support pig hydration and health.
- Service Heating and Cooling Equipment
- Verify heat lamps, brooders, and cooling systems are operating
correctly. Test emergency backup systems to prevent downtime during
temperature shifts.
- Assess Flooring and Penning for Safety
- Inspect for wear, cracks, or damage. Repair or replace broken
penning and flooring to maintain a clean and safe environment for pigs.

The recent ruling out of the Supreme Court on
California’s Prop 12 initiative has created a firestorm within the U.S.
swine industry. The industry plans to fight similar state laws through
different legislative measures. Still, it has a long road ahead to
mitigate the new requirements for swine production out of California.
Producers are concerned on several fronts, from
remodeling to meet the requirements to what is the next piece of
legislation that will require further changes. While some facilities
could easily become Prop 12 compliant today with a herd reduction, many
producers are still contemplating their remodeling options.
Moving to Group Housing
Sow
group housing is not a new concept for the swine industry, but there
was a good reason for the industry to move from outdoor production and
group housing into gestation crates. However, today’s systems and
caretakers have evolved into efficient systems with facilities to
optimize space and the number of sows per employee. Through the use of
gestation crates, producers could implement artificial insemination,
consistent wean groups, and optimal husbandry, which led to substantial
improvements in sow reproduction.
Recent
research (Morgan et al., 2018) refuted previous research to suggest
that transitioning out of the gestation crate back into group housing
was able to lower non-productive days, improve the conception rate, and a
tendency to improve total born. In this trial, injuries and lameness
indexes were significantly higher during the transitionary period but
receded to normal levels after approximately five weeks.
Despite
the pros and cons of group housing, Prop 12 puts another complexity of
converting from gestation crates into group housing. The proposition
requires 24 square feet per breeding animal, and unlike other laws, the
sows cannot be confined more than six hours in 24 hours.
The
square footage requirements of Prop 12 would require producers to
reduce their herds by a third or add additional structures to maintain
current inventories. Either option creates substantial financial
implications for producers. Furthermore, the lack of gestation crates to
breed sows efficiently with current A.I. techniques is challenging,
which has resulted in different housing solutions. In Michigan, for
example, producers can house sows in gestation crates after weaning
until confirmed pregnant at 30 days of gestation.
Best of both worlds
Free
access stalls are one of the innovations that have created an excellent
compromise, bringing together the best of both worlds for swine
producers to meet Prop 12 requirements while utilizing a stall
environment for feeding, breeding, and individual sow treatments and
observations. Many of these solutions have a cantilever-style gate, but
they require complete stall replacement and often include a lot of
moving parts that are noisy and can break easily.
However,
many of these issues have been addressed in the latest free access
stall solutions, such as the Swing-Fix Gate from PigTek. It limits the
need for replacement parts and creates a durable option for equipment
longevity. The system is designed to attach to current gestation crates
and allows the producer to lock in a sow individually or in groups of
25. It helps producers reduce the financial investment of remodeling.
Another design feature is an A.I. gate option that allows easy access
for the breeders.
Consumer
demand and future legislation will continue to move the industry toward
group housing. Thus, the latest free access stalls create the best of
both worlds while considering the needs of the caretakers and the sows.
