Types and Specification of Poultry Cage system. This system involves rearing of poultry on raised wire netting floor in smaller compartments, called cages. Description and knowledge about present and past systems used in poultry farming in cage system. Advantages and disadvantages of cage system.

6. Battery Cage
System
“
Each cage contains between four and ten birds.
• Sometimes called a conventional cage, is
designed to house female chickens who
produce eggs.
• Born in hatcheries -> debeaking-> hens are
sent to the battery cages where they will
spend the remainder of their lives (two years).
• birds are stuffed into communal cages, few
feet across, and 15 inches in height.
• According to 2017 guidelines established by
United Egg Producers, each bird must have
67-86 square inches of space.
• Such tight confinement means that birds
cannot even spread their wings fully without
hitting their cage-mates or the wire sides of
the cage.

7. Why are battery cages banned?
Psychological
problems
Physical
trauma
Forced
molting
Light manipulation
Osteoporosis
Battery cages prevent
chickens from engaging in
most of their natural
behaviors, including
perching, roosting, dust-
bathing, foraging, and
exploring.
The wire mesh floors of
battery cages can cause a
host of foot disorders,
including toe pad
hyperkeratosis,
Hens are denied food and water to force
them to produce more eggs.
Because the number of daylight
hours affects egg production in
laying hens, light can be
manipulated to artificially induce
birds into ramping up
production.
The inability to walk more
than a few paces, to run, or
even to properly stretch their
wings leads to bone fragility
and fractures, especially
during transport.
India: Phase-out completed in 2017

of type of
bird reared

9. Specifications
• Front feeding length : 60 inch
• Front & Back height : 12 inch
• Depth : 36 inch
• No. of chicks (0-8 weeks) per box : 60
• The need to provide auxiliary heat for the animals is called brooding.
• The chick are housed at a temperature between 87 – 92° F (30 – 33° C), at a
relative humidity between 40 – 60%.
• Chick cages are arranged either as single deck or double deck system.
• Feed is usually provided inside the cage during the first week of Grower cage
Brooder cage/chick cage

10. It is used to grow egg-type birds from 9 to 18 weeks of
age.
Specifications
• Front feeding length : 30 inch
• Front & Back height : 15 inch
• Depth : 18 inch
• No. of growers (9 to 18 weeks) per box : 10
Grower cage

11. Layer cage
Two types of stair-
step layer cages are
commonly used in
open-sided poultry
houses
Conventional cages
Reverse cages (Californian
cages)
Specifications for each box:
Front feeding length : 15 inch
Front height : 18 inch
Back height : 15 inch
Depth : 18 inch
A slope of 1/6 is provided in
conventional cages
Specifications for each box: Front
feeding length : 18 inch
Front height : 18 inch
Back height : 15 inch
Depth : 15 inch
reverse cages the slope is 1/5.
In which birds over 18 weeks of age are reared,
usually up to 72 weeks of age.

12. Elevated cage layer house
• The height of the shed : 6-7 feet using concrete pillars.
• Pillar – Pillar distance : 10 feet.
• Two feet wide concrete platforms are made over the pillars.
When 3 ‘M’ type cages are arranged 4 platforms are needed.
• In case of 2 ‘M’ and 2 ‘L’ type cages are arranged 3
platforms are needed.
• When constructing platforms projecting angles or iron rods
to be provided to fix the cages.
• The inter-platform distance is 6-7 feet depending upon the
type of the cages used.
• The total height of the house is 20-25 feet and the width is
30-33 feet.
• This type of house provides sufficient ventilation in tropical
countries.

13. Advantages
• Increased intensity of bird
• Correct maintenance of records
• Identifying poor producers and prompt culling
• Control of vices of poultry cannibalism and egg eating
• It helps in production of clean eggs
• Removal of stress factors
• Easy control of parasitic disease like coccidiosis and worm infestation
• Prompt steps to control feed wastage.
• The cage method of housing is ideal for the area of moderated climate conditions where the
day temperature in summer does not high and temperature does not fall too low.
• Egg production of caged layer was reported to be more then those kept in deep litter system.
• Feed efficiency and egg weight were better in caged birds than the laying flock under deep
litter system.

14. • Difficulties in ensuring proper ventilation to birds especially in summer season and
under very high densed conditions.
• Incidence of leg problem, cage layer fatigue, fatty liver syndrome, flies and
obnoxious gases in the house will be on increases
• Hysteresis of chicks
Disadvantages:
