Aircheck is the element that analyses the quality of the air in the enclosure housing the animals, in real time, controlling the different production parameters, making control in a closed loop possible in order to ensure animal welfare and minimize emissions into the environment.

This device, which records concentrations of NH3, CO, CO2 and O2, apart from temperature and moisture, has a wireless link to the server while automatically recording all the parameters for subsequent analysis and exploitation.

This is the first device worldwide for measuring, recording and storing data on this type of level, particularly for ammonium (NH3), for which there is no product at all on the market. In fact, SINERGIA G6 is already marketing and manufacturing this type of device in view of the importance, in this case, of compliance with the European Regulation.

The fact is that there is already a legal obligation (Directive 96/61/EC, known as the IPPC (Integrated Prevention of Pollution Control, and Directive 2007/43/EC, establishing the minimum provisions for the protection of chickens for meat production, with its corresponding Decrees at Spanish level, see attached) to maintain the levels of ammonium, carbon dioxide, temperature and moisture within certain levels to protect chickens for meat production. Failure to comply would involve the application of the corresponding sanctions system (which may lead to closure of the exploitation for certain types of production) and for which there is no technological solution whatsoever, to date, as regards NH3.

Sinergia G6 provides aftersales service for the annual Calibration of AirCheck by receiving and sending the devices.

Furthermore, the system automatically records all the parameters for subsequent analysis and exploitation. It records concentrations of NH3, CO, C02 and O2, apart from temperature and moisture, equipped with a wireless link to the server.

Failure to comply would involve the application of the corresponding sanction system, (which may lead to closure of the exploitation (Directive 96/61/EC known as IPPC (Integrated Prevention of Pollution Control, and Directive 2007/43/EC, establishing the minimum provisions for the protection of chickens for meat production.

System

Aircheck is a system for measuring gases, recording and storing data, specifically designed for livestock farming. This is the first system on the international market designed to measure:

– Ammonium (NH3)
– Carbon dioxide (CO2)
– Carbon monoxide (CO)
– Temperature (ºC)
– Relative moisture (Hr)
– Oxygen (O2)

• System compatible with the AVI CENTINEL alert system by SINERGIA G6.
• Measures gases in accordance with the regulation (RD 692/2010).
• Improves conversion.
• Improves economic results.
• Easy to install by the user.
• Option of communication via radio between the sensor and the data logger.
• First product to be developed worldwide with the capacity to respond to this need, with its own patent.

Advantages

Improvement of animal welfare

• Reduces plantar dermatitis
• Reduces blisters on breast
• Reduces swollen and/or ulcerated tarsi
• Reduces scabs
• NH3 generates reddish or pale colouring in breasts and the rear part of the tibia-tarsus joints.
• If persistent, skin becomes thicker as a defensive reaction, leading to blisters and swelling, mainly in the breast and areas closest to the sternum.

Productivity

Increases Average Weight and homogeneity
– Important to increase the concentration of O2 and lower NH3, CO2 and CO in order to encourage growth and IT.
– Reduces respiratory diseases.
HIGHLY SUSCEPTIBLE DURING THE FIRST 4 WEEKS
– NH3 breaks the first respiratory defence barrier in poultry, allowing the virus and invading bacteria to pass through.
– When poultry inhale bacteria, virus and other particles, they are trapped in the mucus covering the cila in the windpipe. These cila are small fibres project upwards, forming an elevator carrying the particles in the mucus outward, where the bird can eliminate or swallow them.
– Any damage occurring in the mucociliary elevator reduces the bird’s capacity to eliminate particles and pathogenous organisms from the breathing apparatus. This occurs with levels of NH3 as low as 25 ppm, which are almost undetectable by the human sense of smell.
– High levels of NH cause loss of cilia, which allows immediate access of virus (vaccine included) and bacteria into the lower part of the bird’s breathing apparatus. Such particles cannot be correctly eliminated and they end up in air sacs where air sacculitis develops.

Animal welfare is a factor that should be taken into account, since it influences the bird productivity index.

Animal welfare is a factor that should be taken into account, since it influences the bird productivity index.

Nodoubt it’s a factor that greatly influences the productivity indexes, and there are also regulations which establish the minimum rules for protection (RD 692/2010) that we must abide to.

How is animal welfare measured??
Environment
A proper ventilation should eliminate the heat, humidity and harmful gas excess, and provide enough oxygen.

The maximum concentrations of harmful gas, CO2 and NH3 are regulated by the law as previously stated; but productivity can be affected even at lower doses than the ones reflected in the regulations. To be able to control these parameters, the use of devices to measure the gas levels is essential.

NH3 is the most common cause of decrease in performance in terms of increase of weight and feed conversion. Some exhaustive studies show that even at levels as low as 25 ppm, breeders can lose 19 points of weight per bird (Miles and co. 2009).

Level of NH3 Harmful effects
20 ppm (continuous for 6 weeks) Pulmonary edema, congestion and hemorrhage.
Respiratory disease susceptibility due to ciliostasis.
40 ppm Loss of cilia and decrease in the removal of E. Coli from lungs and air sacs.
25 – 50 ppm Decrease in body weight (0.38 lb. (172 grms) less at 49 days) and feeding efficiency, and increase of airsacculitis when exposed to BI virus.
50 – 100 ppm Keratoconjunctivitis, cornea ulceration and blindness.

Aside from weight loss, the uniformity of poultry is also affected by ammonia exposure.
