Ammonia Sensor Poultry

Ammonia is one of the most common causes of low animal welfare in chicken farms. It is also a major cause of respiratory problems, sores on feet and breasts as well as lower gain.

What is Ammonia?

Ammonia is a chemical compound between the elements nitrogen (N) and hydrogen (H), and has the formula NH3. The substance is found everywhere in nature and occurs naturally in manure and urine.

The smell of ammonia is known, among other things, from the pungent smell of manure or in the environment of a chicken farm.

Ammonia is formed in humans and animals by the breakdown of proteins (albumin) from the diet, or in connection with the ongoing remodeling of all tissues in the body. A part is also formed in the intestine from the breakdown of proteins and other nitrogenous compounds by bacteria.

Ammonia in Poultry Houses

In poultry houses ammonia is a byproducts of manure. When nitrogen compounds are decomposed the result is formation of ammonia (NH3+) and ammonium (NH4-). Ammonia is lighter than air and therefor it floats into the air causing respiration problems and bad smell. Ammonia formation is nurtured by low pH in the litter, high temperatures, and high humidity inside the poultry house.

Why Should You be Concerned About the Level of Ammonia in Poultry?

Ammonia is a major cause of respiratory problems in chickens and a high level of ammonia in the bedding in a poultry house can cause severe sores on the breast and feed of the animals. Ammonia also causes lower weight gain, higher FCR, and decreased animal welfare.

Furthermore, working in an environment with high levels of ammonia is unpleasant and unhealthy to humans.

In some countries in the world, there are legislation on how much NH3 livestock farming can deduce to the surroundings.

How to Measure Ammonia Level in Poultry Houses Using an Ammonia Sensor

There are many different NH3 sensors available at the market, but it is important that you use a sensor, that gives you an accurate meassurement.

Also the quality and lifecycle of the sensor is a very important factor. Most ammonia sensors are quite costly, so replacing them is not something you want to do very often.

At dol-sensors’ we have made ammonia sensors that provide extremely accurate data and are specially designed for agriculture and the harch environment in poultry houses with lots of dust, temperature swings, and high humidity. Our sensors are negligible cross sensitivity to other gasses and work in both high and low NH3 concentration.

As a special feature you can just change the filter on the sensor instead of changing the whole sensors. This is both a much cheaper solution, better for the environment, and a lot easier.

How to Lower Ammonia Level in Poultry

Since chickens are depending on fairly high temperatures, lowering the temperature is not a possibility, when aiming at reducing the formation of ammonia.

However, lowering humidity and litter pH will have a very possitive effect on formation of ammonia. This can be done by adjusting the ventilation rate and changing bedding between batches.

You can use DOL 114 to keep track on the temperature and humidity in poultry.

Consumer Trends And Preferences In Poultry Products
Learn how continuous monitoring helps producers identify developing production challenges through changes in water consumption, growth performance and other key production indicators.

Poultry products have long been a cornerstone of global diets, but in recent years the way consumers choose, purchase, and consume them has been shifting. Evolving preferences, health considerations, sustainability concerns, and technological innovations are reshaping demand across markets. Understanding these dynamics is critical for producers, retailers, and policymakers aiming to align supply with changing consumer behavior.

Health and Nutrition as Key Drivers

Health consciousness has become one of the most powerful forces shaping consumer demand in the poultry industry. Increasingly, buyers are drawn to poultry—especially chicken—because it is widely perceived as a lean, high-quality protein that contains less saturated fat than red meat. This aligns with popular dietary patterns such as high-protein, low-carb, and weight management plans, making poultry a flexible option across diverse lifestyles.

At the same time, consumers are looking more closely at how poultry is raised and processed. The demand for products labeled antibiotic-free, hormone-free, or organic has surged, reflecting concerns about food safety, long-term health effects, and transparency in farming practices. According to recent market analyses, shoppers are also showing growing interest in “functional” poultry products, such as chicken enriched with omega-3 fatty acids or raised with specialized feed to improve nutritional content. These preferences indicate that health is no longer defined only by calorie counts or fat levels, but by the overall integrity of the food chain. In this sense, poultry producers who emphasize clean, natural, and responsibly raised products are aligning with a major consumer priority.

Shift Toward Convenience

Busy lifestyles and urbanization are driving demand for poultry products that save time and effort. Ready-to-cook marinated chicken, frozen nuggets, and pre-cooked deli meats are increasingly popular in both developed and emerging markets. Packaging innovations - such as resealable packs and portion-controlled servings - enhance convenience and reduce food waste, aligning with consumer expectations.

How to Reduce Feeding Costs in Poultry Production
Learn how continuous monitoring helps producers identify developing production challenges through changes in water consumption, growth performance and other key production indicators.

Feed accounts for up to 70% of total production costs in poultry farming, making it the single largest expense for most producers. With fluctuating ingredient prices and increasing competition, finding effective ways to reduce feed costs—without compromising bird health or productivity—is essential for profitability.

Here are five expert strategies to help you cut feeding costs and improve efficiency on your poultry farm.

1. Consult Poultry Feeding Experts for Smarter Formulation

One of the most effective ways to cut feed costs without hurting performance is to work with qualified poultry nutritionists or feeding experts. These professionals understand how to balance nutrients efficiently while using locally available and affordable ingredients.

A feeding expert can:

  • Help you design least-cost rations that meet your birds’ nutritional needs.
  • Identify suitable alternative feed ingredients (like cassava, sorghum, palm kernel cake, or sunflower meal).
  • Analyze ingredient nutrient profiles to ensure you’re not overfeeding expensive nutrients.
  • Continuously adjust feed formulas as market prices and ingredient availability change.

By relying on expert advice instead of guesswork, farmers can achieve better feed efficiency, maintain bird health, and save significantly on overall feed expenses.

2. Minimize Feed Wastage

Even the best feed formulation is useless if much of it ends up on the floor. Feed wastage can silently drain profits, sometimes accounting for 5–10% of total feed losses.

Here’s how to reduce waste:

  • Use feeders with proper design and adjustable height to minimize spillage.
  • Fill feeders only up to two-thirds full.
  • Raise feeder levels as birds grow to avoid scratching out feed.
  • Keep feed storage areas dry, cool, and pest-free to prevent spoilage and contamination.

Simple management changes like these can save thousands of dollars over time.

3. Adopt Phase Feeding Programs

Birds have different nutritional needs at each stage of growth. Using the same feed throughout their life leads to waste and inefficiency.

Phase feeding means adjusting feed composition based on the bird’s age and production stage—for example:

  • Starter, grower, and finisher diets for broilers
  • Pre-lay, peak-lay, and post-peak diets for layers

By tailoring nutrients to each phase, farmers can save 5–8% in feed costs while maintaining growth rates and egg production.

Humidity Sensors
