Poor Fan Performance = Big Problems in Poultry and Livestock Operations

Your barn's ventilation system plays a vital role in maintaining healthy environments for broilers, layers, and other livestock. When cooling fans underperform due to worn or slipping belts, the consequences are serious:

• Heat stress causes decreased egg production and lower feed intake.
• Bird growth is stunted, affecting market weight and yield.
• Poor air quality leads to high levels of ammonia and carbon dioxide, which harm both animals and workers.

Proper fan operation is your frontline defense. And it all hinges on a belt that’s working as hard as you are.

The High Cost of Slipping Belts

Slippage in a fan belt might seem like a small issue, but the hidden costs are huge. A properly tensioned, brand-new belt offers near full efficiency. But if your belt is slipping—even just a little—you could be losing 20% of your airflow.

That’s not just bad for ventilation; it’s bad for your wallet.

• Each tunnel fan with a slipping belt can waste up to $60 in energy per season (based on average operating hours, kWh cost, and fan size) 
• A replacement D&D belt costs around $10
• That’s a $50 savings per fan—and that doesn’t even count the cost of animal stress or downtime

Replacing your livestock barn fan belts annually is a no-brainer. It's low-cost insurance that keeps your systems efficient and your animals healthy.

Don’t Trust What You See—Trust a Maintenance Schedule

One of the biggest misconceptions in barn maintenance is assuming that a belt that looks good is still doing its job. But visual checks aren’t enough.

Unless you’re monitoring tension and watching for slippage, you’re probably missing performance loss. That’s why we recommend implementing regular cooling fan belt replacement into your annual spring maintenance:

Set your clocks forward. Change your smoke detector batteries. Replace your fan belts—every time.
