Why Good Barn Air Matters More Than Ever

Air quality has always shaped poultry, but today it plays an even bigger role in flock performance, welfare, and overall farm efficiency. As production becomes more intensive and expectations for animal well-being rise, maintaining good barn air is no longer just a management task - it's a strategic advantage.

The Hidden Impact of Air

Poultry barns naturally generate dust, moisture, and gases like ammonia and CO₂. When ventilation or climate control slips, these elements build up quickly and begin to affect the birds long before visible symptoms appear.

Poor air quality can lead to:

  • Slower growth and reduced feed efficiency
  • Higher susceptibility to respiratory infections
  • Increased stress and uneven flock behavior
  • Wet litter and higher ammonia levels
  • Greater need for interventions and treatments

Even small deviations in air quality can quietly erode performance across an entire flock.

Why Air Quality Matters More Today

Modern poultry production demands tighter environmental control than ever, and that makes good barn air a crucial part of flock management. Higher stocking densities generate more heat, moisture, and gases in the same space, while today's fast-growing genetics leave birds more sensitive to even small environmental stressors. Welfare expectations call for stable and predictable conditions throughout the entire production cycle, and economic pressure means every point of feed conversion and every ounce of weight gain matters. Air quality isn't just a comfort factor - it has become a core driver of both flock welfare and overall profitability.

The Role of Continuous Monitoring

Manual checks alone can't keep up with the speed at which barn conditions change. Temperature, humidity, CO₂, and ammonia can shift within minutes - especially during weather changes or equipment failures.

Digital Monitoring Tools Provide:

  • Real-time insight into environmental conditions
  • Early warnings when ventilation or heating drifts off target
  • Data trends that reveal recurring issues
  • A more stable and predictable climate for the birds

Better Air, Better Birds

Good barn air is more than a comfort factor - it's a performance driver. Birds breathe easier, move more, eat more consistently, and convert feed more efficiently. Litter stays drier, disease pressure drops, and the entire production cycle becomes smoother.

Ammonia Sensors

It is well-proven that air polution due to high ammonia levels in broiler production results in a higher FCR, lower gain, and poorer animal welfare. Birds being exposed to high levels of ammonia can suffer from respiratory deseases, ammonia blindness, infections with Newcastle, the bronchitis virus and parasites, burned skin and feed, nutritional stress, suffocation, and even death. These sufferings will of course decrease production and increase breeding costs.

Early action benefits the productivity of the broilers as well as animal welfare. Thus, constantly monitoring the level of ammonia is essential for the poultry production. Furthermore, monitoring the level of humidity is also important, since a too high level of humidity in the livestock hous can cause formation of ammonia.

There are different ways to minimize the level of ammonia in a poultry production. One is ensuring a good quality of litter, air flow and ventilation in the house, a low level of humidity, and keeping the temperature down. Minimizing the level of ammonia have a major impact on the financial yield of the production. In fact, studies* have shown that ammonia concentrations as low as 25 ppm can reduce bird weights at 28 days of age by 2-7% while 50 ppm ammonia has been shown to reduce bird weights from 16-19%. An increased ammonia concentration can cut profits by $3,000 or more per batch in a livestock house with 25,000 broilers.

With dol-sensors’ ammonia sensors you can continuously monitor ammonia levels with great accuracy. Combined with a farm controller, the ammonia sensors can help ensuring automation of the ventilation system.

Estimate Weight of Pig
Learn how continuous monitoring helps producers identify developing production challenges through changes in water consumption, growth performance and other key production indicators.

Looking to estimate the weight of a pig quickly and accurately? Our iDOL 65 Pig weighing camera is designed to help you calculate pig estimated weight without using a physical scale. Whether you’re a farmer, veterinarian, or breeder, reliable pig body weight estimation is essential for feeding, health management, and sales planning.

How to estimate pig weight

Many people ask how to estimate pig weight when scales are unavailable. The most common method is to use body measurements such as heart girth and body length. These values are used in proven formulas for weight estimation in pigs, giving a dependable estimate of live body weight.

Pig body weight estimation for live pigs

Our system focuses on pig body weight estimation for live animals. This approach makes it easy to estimate weight of pig at different growth stages while minimizing stress for the animal. Accurate pig estimated weight helps improve feeding efficiency and ensures animal welfare.

Pigs Seek Human Attention, but on Their Own Terms

New research shows that pigs are far more socially aware than many people assume. When they want something, they actively try to get a human's attention -and they often use strategies similar to those seen in dogs. But unlike dogs, pigs tend to be a bit more self-reliant and selective in how they interact.

How Pigs Communicate with Humans

Research observed that pigs use a mix of vocalizations, body language, and direct eye contact when they want help or attention. They may nudge a person, stand in their line of sight, or repeatedly look back and forth between a human and an object - a behavior known from dogs trying to "show" their owners something.

A Key Difference from Dogs

While dogs have been bred for thousands of years to cooperate closely with humans, pigs have not undergone the same domestication process. This means pigs show attention-seeking behavior, but they don't rely on humans in the same way. They tend to switch strategies quickly and may try to solve the problem themselves if the human doesn't respond fast enough.
