Ventilation Management in Poultry Houses

Ventilation Systems
Depending on different ventilation requirements, ventilation systems are generally divided into two types: (1) natural air flow system and (2) mechanical air movement (fans). Sometimes it is also combined to provide comfort to the chickens.
Natural air flow system
Ventilated shelters must be exposed to the wind, so place the building on a high site rather than in a low place at least 100 feet away from the side where the prevailing wind enters the building.
Winter Ventilation: Systems for cold weather are much more complicated than for warm weather because houses must be closed tightly for comfort and to conserve energy. Tight enclosures trap the gases, odors, humidity, etc. that must be dealt with continuously for the health of the birds.
Summer Ventilation: A natural air system is used for warm weather conditions in houses with side curtains. This system uses temperature differences and natural air movement to remove excess heat and moisture, and to supply oxygen. 

Mechanical ventilation system
Mechanical air movement is required to properly ventilate a house in all extreme climatic conditions.  They can be divided into two distinct types: (1) negative pressure and (2) positive pressure. 

Negative (Exhaust) System: In the negative pressure system, fans are arranged to expel air from the building.

Positive Pressure System: A positive pressure system uses fans to push air into the building and create a positive pressure.

The Significance of Ventilation in Poultry Management

Poultry house plan is important to guarantee optimal airflow for bird cooling and comfort. At the point when planning a modern broiler house the main question one considers is the ideal floor zone for the best return on investment (ROI). Also, and similarly essential, is the thing that air exchange and velocity is expected to keep the birds agreeable, and by what means will this impact energy costs?

The essential objective of broiler farmer is to empower feed consumption from the minute the chicks land on the farm to when they leave for butcher.

The initial seven days in the life of a chick are the most vital. The brooding period sets the point of reference for good execution and additional exertion then will be compensated in definite run execution. To guarantee a decent begin, the producer must give a situation that guarantees ideal quick admission of sustain and water.

The other most difficult period, particularly in the hot season is the grow-out phase – following 25 days. Birds are completely feathered and hot surrounding conditions will challenge sustain utilization.

These are some vital plan contemplations:

1. Very much protected smooth roofs and walls.

2. Great quality channels for least and move ventilation

3. Satisfactory static weight control, by intensive fixing of houses. Every new venture ought to be appointed simply after weight testing.

4. Tunnel fan decision in light of proficiency – not cost! Fan decision will be the most imperative outline choice, particularly in hot atmospheres.

The rooftop and/or drop roof protection is a standout amongst the most critical parts of any new house extend. The best alternative is to introduce protection either on top of the drop roof or against the rooftop.

The sum that the air in a house heats up down the length of the house depends fundamentally on three elements:

1.         Metabolic heat included by the broilers

2.         How rapidly the air in the house is exchanged.

3.         Thermal properties of the house

To summarize, the key plan choices in any new venture are by far insulation; inlet choice and its establishment; the house’s capacity to keep up sufficient weight; and the decision of passage fan.




Litter is an important aspect of the deep litter housing system. This poultry litter is the source of volatilized ammonia and its management is a key factor that affects the rate of its emission and the health of birds. Keeping litter dry is a critical part of the management of poultry farms. Caked litter increases the ammonia level thus negatively affecting the broiler’s health, welfare, growth performance, and carcass quality. High ammonia levels in poultry houses can result in poor bird performance and health which causes loss of profits to the grower and integrator. Birds are often more susceptible to infections of the respiratory tract when exposed to high levels of ammonia.

The presence of organic waste from the feed, feces, and favorable shelter, temperature, light, and moisture conditions result in the development of large populations of the pathogens. This can reduce the flock productivity and damage the health of animals.

To combat such problems in poultry houses we at Vinayak Ingredients have launched a product with the brand name “Essentiolitt Poultry” which is a blend of Essential oils and works as a litter amendment system and works on various principles like a desiccant, pH control, nitrogen, and phosphorus optimization, poultry sanitizer and litter conditioner.

The unique natural ingredients in the product have been formulated which provide the following benefits:

  1. Re-balancing the natural ecosystem of the litter, which are toxic to humans and birds
  2.  Balancing the pH which is essential to control to the growth of bacterial toxins and constantly consume organic matter that regenerates the natural balance of the litter.
  3. Regenerating the entire litter bed allowing it to be used longer for safe and healthier birds as well as non-toxic to humans.
  4. Acting as a Bio-aerosol cleanser wherein essential oils bind to bio-aerosols thereby preventing respiratory problems in the birds.
  5. Giving a desiccant effect which helps in maintaining the moisture content that is essential to reduce the formation of ammonia.
  6. Having Anti-urease and Anti-uricase property which ultimately leads to no ammonia formation.
  7. Maintaining Dry litter that helps in controlling the ammonia level, providing a healthy flock environment, and reducing condemnations due to hock, footpad burns, and breast blisters. 
  8. Destroying the pathogenic microflora in the litter by acting as a disinfectant.
  9. Acting as an odor control program
  10. Accentuating the growth of beneficial microflora for better litter to manure conversion.
