Managing Ammonia During Winter in Deep Litter Broiler Houses
Ammonia buildup in poultry houses, particularly during winter, poses a significant challenge for poultry farmers. Effective ammonia management is crucial for ensuring bird health and maintaining optimal productivity levels. Below, we explore how ammonia forms, its risks, and practical solutions, including poultry equipment for controlling ammonia in deep litter broiler houses during the colder months.
How Does Ammonia Form?
Ammonia (NH₃) primarily originates from manure that accumulates in deep litter systems. As litter moisture levels rise, they create an ideal environment for bacterial activity, which breaks down nitrogen compounds in the manure. One of the key byproducts of this breakdown is ammonia. High levels of ammonia can have detrimental effects on both poultry health and worker safety, especially during winter months when natural ventilation is limited.
Ideally, ammonia concentrations in poultry houses should remain below 25 ppm (parts per million). When levels exceed this threshold, it can negatively impact bird respiratory health, reduce productivity, and even increase mortality rates. During winter, outside temperatures are low, reducing the effectiveness of ventilation fans. This creates a situation where toxic gases, including ammonia, accumulate inside the house due to limited airflow, further exacerbating the problem.
In broiler poultry farms that rely on sidewall curtains and lack effective minimum ventilation systems, maintaining optimal temperatures becomes challenging. During the brooding stage, chicks require temperatures between 32°C and 36°C. However, due to the heat loss through side curtains and poor insulation farmers never achieve these temperature levels. Therefore, most farmers try to cover the house by covering the brooding area and providing additional covers on the side curtains. Consequently, these additional closures trap the air ventilation and contribute to the increase in toxic gases inside the house. When ventilation is inadequate, ammonia buildup becomes more pronounced, especially as warmer temperatures accelerate the breakdown of uric acid in the manure, leading to higher ammonia concentrations.
In such conditions, farmers often attempt to mitigate ammonia by opening side wall curtains halfway. While this allows for some gas exchange, it is not enough to maintain proper ventilation, resulting in a dangerous rise in ammonia levels. To combat this, some farmers use large fans to improve air circulation. However, these fans expel significant amounts of warm air, leading to increased heating costs and further temperature fluctuations.
Additionally, the lack of insulation in many poultry houses contributes to excessive heat loss, making it harder to maintain a stable indoor environment. This not only increases heating requirements but also complicates ammonia management.
Poultry Industry Equipment: Solutions for Managing Ammonia in Winter
Winter Ventilation Equipment:
Proper winter ventilation is essential for controlling ammonia levels. Minimum ventilation fans are key to removing toxic gases without causing excessive air drag. These fans are designed to exhaust just enough air to prevent ammonia buildup while maintaining stable temperatures. Proper side air inlets are also vital they ensure that cool air does not directly blow over the birds and help maintain even airflow throughout the house.
Tunnel inlets are effective at blocking drafts and preventing wind chill from affecting the birds. This helps create a stable and comfortable environment even in cold weather.
Insulated House Design:
One of the most effective ways to manage ammonia during winter is to ensure your poultry house is properly insulated. Insulated walls, roofs, and ceilings help retain heat, reducing the reliance on supplemental heating equipment. The recommended insulation levels for poultry houses are between R-19 and R-25. This insulation not only reduces energy costs but also helps maintain a consistent internal temperature, supporting bird health and well-being.
Insulation also aids in better ammonia control. By reducing the need for excessive heating, you can avoid overworking ventilation systems, which are crucial for managing both temperature and air quality. Proper insulation limits heat loss and makes it easier to maintain the required airflow and ammonia levels.
Reliable Climate Control Systems:
A well-maintained climate control system is essential for monitoring and regulating the poultry house environment. These systems control ventilation fans, inlets, heaters, and humidifiers, ensuring that all equipment works together efficiently. The use of accurate sensors for temperature, humidity, and static pressure allows for precise control, which is critical during winter when conditions can fluctuate rapidly.
By continuously monitoring and adjusting the environment, climate control systems help maintain the ideal temperature and humidity levels for poultry, improving both productivity and bird health. Additionally, this reduces the strain on heating systems and helps manage ammonia buildup more effectively.
Keep the Litter Dry:
Although this isn't a poultry equipment-specific solution, it plays a crucial role in efficient broiler feeding and broiler farming. Moisture in the litter is one of the primary contributors to ammonia production. To control ammonia levels, it's essential to keep the litter as dry as possible. Properly adjusted drinkers can help prevent water spillage, which is a common cause of wet litter. Regularly inspect the water system for leaks, and address any issues promptly.
If the litter becomes too wet, it is important to add dry bedding material to absorb excess moisture. This will help maintain the balance of the litter and reduce the likelihood of ammonia buildup. Additionally, periodic litter management practices such as turning the litter can help further reduce moisture and ammonia concentrations.
