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.
