Overview Of A-Type Poultry Battery Cages



A-type poultry battery cages are sloped multi-tier housing systems widely used for commercial egg production. 

They are designed to maximize stocking density and simplify management tasks such as feeding, egg collection, and manure removal.

From an engineering perspective, the system is a combination of structural steel framing, wire mesh partitions, automated or semi-automated feeding lines, and water delivery units. 

While efficient in space utilization, the system introduces several operational and biological constraints that must be managed carefully.



System Structure And Technical Composition



A-type cage systems rely on a triangular frame geometry, which supports multiple stacked rows of cages. 

Each layer is designed to maintain egg roll-off angles and manure separation efficiency.

Cage Structure ParameterValue
Cage Inclination Angle (Degree)7.5
Steel Wire Diameter (Mm)2.8
Tier Spacing Height (Cm)42
Frame Width (Cm)120
Single Cage Depth (Cm)60

The geometry directly influences bird movement, egg flow, and waste distribution efficiency.



Airflow Inconsistency In Closed Houses



Air distribution inside poultry houses often becomes uneven due to structural blockage from cage rows.

Airflow Measurement PointAir Velocity (M/S)
Inlet Zone A1.85
Central Aisle0.92
Upper Tier Edge1.10
Lower Tier Rear0.76
Exhaust Zone2.30

Reduced airflow in central zones leads to localized environmental stress and uneven flock performance.



Gas Concentration Accumulation



Ammonia and carbon dioxide levels vary significantly depending on manure removal frequency and ventilation efficiency.

A-Type Poultry Cage Density And Structural Configuration Overview



A-type poultry battery cage systems use a modular tier design to increase production capacity while keeping the same floor footprint. 

This structure allows farms to expand vertically without changing house length or width, making planning and equipment layout more stable. 

Standardized cage geometry also helps maintain consistent bird distribution and simplifies daily management tasks such as feeding and watering.

Cage TypeTier Per SetUnit Size (M)Cells Per SetBirds Per SetSpace Per Bird (Cm²)
A132.2 x 2.4 x 1.8530120418
A242.2 x 2.4 x 2.240160418
A352.2 x 2.4 x 2.850200418

From A1 to A3, increasing tiers raises total bird capacity per set while keeping stocking density unchanged. 

This stable density design helps maintain predictable production output and reduces variation in feeding and environmental load across different housing scales.



Frequently Asked Questions



Q1: Why does airflow become uneven in cage houses?

Cage stacking geometry blocks airflow pathways. 

Central aisle velocity may drop below 1.0 m/s depending on layout density.

Q2: What causes egg breakage during transport?

Mechanical vibration occurs at conveyor joints. 

Certain transition points record over 70 breakages per 10,000 eggs.

Q3: How often should manure be managed in A-type systems?

A 3.2-hour cycle stabilizes ammonia concentration and keeps moisture under controlled range in lower collection zones.
