Pigs cooling: systems for healthy, productive pigs

As summer temperatures rise, the impact on pig welfare and performance becomes increasingly significant. Pigs are unable to sweat, which limits their ability to regulate body temperature effectively. Once temperatures exceed their thermal comfort zone, they are at risk of heat stress: resulting in reduced feed intake, slower growth, impaired reproduction, and, in severe cases, mortality.

For pig producers, heat stress not only compromises animal welfare but also leads to substantial economic losses due to lower productivity and increased veterinary intervention. This makes advanced pigs cooling and pig barn climate control solutions a critical component of efficient, future-proof pig farming.

Why are pigs sensitive to heat?

Pigs are particularly vulnerable to heat for several biological reasons:

They have minimal sweat glands, limiting their ability to cool down through the skin.
They primarily rely on panting, which becomes ineffective in hot, humid conditions.
Their thick fat layer retains body heat, increasing thermal stress.

How do pigs cool down?

In natural settings, pigs regulate their temperature by wallowing in mud or water, cooling their bodies through conduction and evaporation, while also gaining protection from sunburn and insects. In modern pig housing, pigs depend on environmental controls such as ventilation, shading, and dedicated pigs cooling systems to maintain a stable and comfortable climate.

When internal heat accumulates and pigs can’t release it, their metabolic rate slows and feed intake drops, affecting growth, fertility, immunity, and overall welfare. This is why effective cooling systems for pig farming are essential.

Cooling solution: indirect cooling for pig barns

Indirect cooling is one of the most effective and animal-friendly technologies available for pig barns. It works similarly to air conditioning: fresh air is first cooled outside the barn using chilled water or another medium, then evenly distributed indoors.

Advantages of indirect cooling:

Maintains low humidity levels inside the barn, unlike evaporative systems.
Ensures a stable indoor climate regardless of external weather.
Filters incoming air, reducing dust and airborne pathogens.
Highly energy-efficient, especially when integrated with smart ventilation systems.

By supplying consistently cool and clean air, indirect cooling helps reduce heat stress in pigs, keeping them healthy and productive without sudden temperature shocks.

Invest in the right cooling system

Keeping pigs cool is not just about comfort—it’s a cornerstone of animal welfare, productivity, and profitability. Whether upgrading your current setup or planning a new barn, investing in the right pigs cooling solution will pay off for both your animals and your business.
