The document discusses the requirements and layout for producing sterile parenterals. It describes the different sections needed - cleanup, compounding, aseptic, quarantine, and packing/labeling. Specific requirements for the aseptic area are outlined, including environmental controls like particle counting, slit to agar sampling, and Rodac plates to evaluate air quality. Floors, walls, and benches must be smooth, impervious, and easy to clean. Proper ventilation and filtration of air is essential to maintain sterility. Sources of contamination and prevention methods are also covered.
The document discusses plant layout, which refers to the arrangement of machinery, equipment, and other physical facilities within a factory. The overall goal of plant layout is to optimize material flow and minimize costs. There are different types of layouts, including product layouts that arrange machines by the sequence of operations, and process layouts that group similar machines together. When designing a layout, factors like the factory building, production process, type of equipment, and human needs must all be considered.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
2. A hatchery is not a typical industrial building; it is
highly specialized with unique requirements for
construction and operation
WHAT TO CONSIDER WHEN DESIGNING A
HATCHERY
HOW TO MEET YOUR ROOM REQUIREMENTS
DESIGNING THE HATCHERY VENTILATION SYSTEM
3. WHAT TO CONSIDER WHEN DESIGNINsG A
HATCHERY
1. Determine the Budget
2. Set a Production Capacity
3. Confer with an Experienced Design Consultant
4. Designing the Ventilation System
5. Selecting the Best Hatchery Site
6. Choose Hatchery Equipment Wisely
7. Developing a Preliminary Floor Plan
8. Two Basic Floor Plans for Hatcheries
9. Selecting Building Materials
10. Meeting Floor and Drain Requirements
11. Choosing Hatchery Doors
4. 1. Determine the Budget
Costs vary considerably
depending upon capacity
construction materials and methods
equipment selection
engineering
geographical location
automation
Keep one goal in mind:
the construction of an efficient building, at a reasonable cost,
that consistently produces a maximum number of live chicks
per eggs set
Identify available resources and budget constraints before
beginning the planning and construction phases
5. 2. Set a Production Capacity
Future requirements
Design and construct the hatchery with a final
production capacity as a goal
If the objective is for the hatchery to produce one
million birds per week, a specific number of incubators
and hatchers are required
These machines, in turn, require a specific amount of
space. Likewise, the size of egg storage, processing
areas, and mechanical room will all be relative to
production capacity; as will the cost, of ventilation,
plumbing, electrical, and mechanical systems
6. 3. Confer with an Experienced
Design Consultant
Hatchery plans must be developed to meet the specific
needs of the owner
The design consultant should fully understand the
requirements of incubation equipment, including
ventilation, floor construction, slopes and drains, and
minimum space requirements
In addition, the design firm should be well-versed in the
production process, which includes workflow, room
sizing, waste disposal, and automation (miscellaneous)
equipment layout
7. 4. Designing the Ventilation
System
Except for the incubators and hatchers themselves, the
overall ventilation system is probably the single most
important component in the hatchery
Proper conditioning of the fresh air supply almost
always presents a formidable challenge
Furthermore, inadequate ventilation will severely affect
the performance of incubators and hatchers
Improperly designed heating, ventilation, and air
conditioning systems (HVAC) will produce a poor
quality chick, lower hatch rate, and a major loss in
profits over the life of the hatchery
8. 5. Selecting the Best Hatchery
Site
Before breaking ground for the new hatchery, choose an
appropriate location
Site selection affects the profitability of the entire operation,
as well as the overall performance of the hatchery
The greater the distance from breeder farms and grow-out
houses, the higher the transportation costs
However, in order to provide biosecurity, the hatchery
should be situated far enough away from the production
units to minimize the spread of disease
The availability and cost of labor, utilities (including water,
electricity, gas, or fuel oil), and waste disposal are also
concerns
Generally, a hatchery should be located on high ground and
should have good drainage.
9. Cont…..
Up to 3,000 ft (610 m) above sea level = optimum elevation
More than 3,000 ft (610 m) above sea level = some loss in
hatchability
The greater the distance between the hatchery and other
agricultural buildings, the more suitable the site
Hatcheries must be located at least 1,500 ft (460 m) from other
poultry buildings
The site should be isolated from grain storage, feed mills, or other
dust-producing activities.
Consider prevailing wind direction and make certain that the
hatchery is located upwind of these facilities. Soil composition
can also affect the cost of construction.
Finally, check carefully for zoning ordinances, building codes, and
restrictions that may apply to the property.
10. 6. Choose Hatchery Equipment
Wisely
The equipment selected is critical to hatchery performance
Choosing incubators, hatchers, ventilation equipment,
environmental controls, computerized systems for data
purchase, processing and automation equipment,
generators, boilers, etc. all affect the success of the
operation
These decisions also have a major impact on the total cost
of the project
Whenever possible, choose custom products designed and
manufactured specifically for hatchery applications instead
of "off the shelf" products
11. Conti…..
Automation will affect the layout and size of the hatchery
While the initial investment in automation will be substantial, the
benefits can be realized through reduced labor costs and efficiency
Equipment will be subjected to frequent washing with water and
detergents, and may be exposed to corrosive disinfecting chemicals
Anodized aluminum, stainless steel, and non-reactive plastics are
most suitable for the hatchery
In heavy traffic areas, equipment should be suitable to withstand the
impact of a fully loaded egg buggy
Choose equipment that is proven reliable, easy to service, safe to
operate, energy efficient, and capable of continuous duty
Also consider the availability of replacement parts, service
representatives, and technical assistance
12. 7. Developing a Preliminary Floor
Plan
Hatchery design and ventilation specialists can assist in the
development of a preliminary floor plan
This floor plan will be needed to further define budget and
overall design criteria
A preliminary floor plan must be designed around the
requirements of a specific incubator manufacturer, and
must take into account the production capacity of the
hatchery, future expansion plans, and equipment selections
Generally, the rooms should be arranged in order from
clean to dirty, taking into account the flow of eggs and
chicks from one area to the next
13. 8. Two Basic Floor Plans for
Hatcheries
Incorporate either a “rectangular” or "T"-shaped design
The rectangular building often used for small
hatcheries, has good work-flow and excellent space
utilization, with minimum square footage
The rooms are oriented in a clean to dirty progression
But this design is less suited for expansion and lacks
some bio-security features found in the "T" shape
14. Cont..
The most common building style today is the "T"-shaped
design
In these layouts, incubator and hatcher halls are located in
each wing and are separated from storage and processing
rooms by a corridor
The egg room, clean tray room, wash room, and chick
processing room are in the center area of the building
This design gives the option of starting small by building
only one wing, with a center area large enough to
accommodate a future wing
It also has good workflow and easily lends itself to a good
sanitation program
15.
16.
17. 9. Selecting Building Materials
Construction costs will depend upon the type of
building materials selected
Common materials include
1. prefabricated metal structural components
2. concrete block (CMU), precast concrete
3. insulated lamina metal panels
In some cases, a combination of these materials may be
used. Each has its advantages and disadvantages
18. 10. Meeting Floor and Drain
Requirements
The hatchery floor should be built to withstand the toughest
conditions; provide for proper drainage; and have a smooth,
durable surface finish
Concrete floors with imbedded steel to prevent cracking are
the best choice, and the concrete should be a minimum of 4
inch (10.2 cm) thick
The floors under the incubators and hatchers must be both
level (within 1/4 inch (6 mm) in 10 ft (3.05 m)) and flat
(within 1/8 inch (3 mm) in 2 ft (0.6 m))
Irregularities in the floor adversely affect the installation
and operation of equipment
If possible, avoid floor joints under hatchery equipment
Protect all floor areas subjected to buggy traffic with a
quality floor-hardening material
19. Cont…….
Never use glazed tile on hatchery floors
Tiles break under the load of egg buggies and are
slippery when wet
Locate an adequate number of floor drains for all
processing areas, from egg receiving through chick
delivery
Drains should be conveniently located near the setters
and hatchers
A floor slope of 1/8 inch (3 mm) per linear foot is
recommended for all floor drains
20. Cont……..
Trenches are commonly used in high use areas, such as
hatcher, wash, and take-off rooms, to speed up drainage
Drain covers and openings should be large enough to
allow for drainage of water and smaller eggshell
particles, but small enough to allow egg buggy wheels
to roll smoothly over them
Drains in hatcher, wash, and take-off areas should also
include a catch basin for trapping particulate matter,
and as a rule, 6 inch (15 cm) lines are adequate for all
floor drains
21. 11.Choosing Hatchery Doors
Hatchery doors in all areas having buggy traffic should be double-
door, double-action, and self-closing with view windows
These doors should be equipped with complete air seals and
impact bumpers
Recommended door openings are 7 ft (2.1 m) high and 6 ft (1.8 m)
wide
Non-traffic doors are usually single or double doors, hollow core,
single action metal with automatic closures
Typical options in these doors include view windows, push plates,
and traffic bumpers
Dimensions for single leaf doors are 7 ft (2.1 m) high and 3 ft (0.91
m) wide. Double leaf doors are 7 ft (2.1 m) high and 6 ft (1.8 m)
wide.
The egg-receiving and chick-bus bay areas require insulated
rolling overhead doors. Larger doors of this type are usually
motorized with remote start / stop buttons
22. 12. Where to Install Ceilings
When possible in hatcheries, ceilings should be limited
to office and break areas
Drop ceilings using 2 by 4 ft (0.6 by 1.2 m) panels are
suitable in these areas
Ceilings may also be required in the incubator, hatcher
and other process areas
When the structure has exposed bar joists or similar
components, a suspended 4 by 8 ft (1.2 by 2.4 m)
insulated metal panel system with heavy-duty
aluminum tee grids is recommended
Precast roof systems do not require ceiling installation
23. 13. Designing Interior Walls
The interior walls of the hatchery should:
have a smooth, durable surface suitable for frequent washing
be strong enough to withstand considerable abuse
provide for an air-tight seal between rooms, and the rooms and
outside
Concrete block, finished with pore filler and epoxy paint, is a good
option, but will require periodic painting
A much more durable, although more expensive option, is a wall
system consisting of concrete block covered with glazed tile
This system is essentially maintenance-free and is much easier to
clean than a painted surface
Many hatcheries also use insulated metal or plastic panel systems
that provide for good sanitation, can be well sealed, and require
relatively little maintenance.
24. 14.Evaluating Water Supply
Securing an ample supply of water for the hatchery is
crucial
Water is required for setters, hatchers, room
humidification, and sanitation
Although a common water supply can be used for all
these applications, it normally best to use dedicated
lines for each application
When using dedicated lines individual temperature,
flow rate, and pressure can be provided for each
application
25. Cont….
There are four important factors when considering a water
supply
1. Temperature
1. Incubator cooling water
2. Machine and room humidity water
3. Hatchery sanitation water
2. Pressure
1. Machine cooling water
2. Machine humidity water
3. Room humidification water
3. Quality
4. Volume
26. Conti..
Temperature
1. Incubator cooling water
The optimum temperature range for machine cooling water
on the maximum room temperature expected
If room temperatures can be maintained between 80° and
85°F (26° and 29°C), then cooling water temperature at the
machines should be between 65° and 75°F (18° and 24°C)
The room temperature is between 85° and 90°F (30° and
32°C), then cooling water temperature at the machines
should be between 55° and 65°F (13° and 18°C).
27. Cont….
Some hatcheries use well or city water for cooling and as
long as the water temperature can be maintained within the
recommended range, it is acceptable
In larger hatcheries where sewer and water services can be
expensive, the installation of a chiller where water can be
recycled may be justified
When utilizing a chilled water system, the same water is
recirculated, thus eliminating a fee for sewer and water
A chilled water system also has the ability to adjust water
temperature to best satisfy the requirements of the
machines
It is important to insulate all water lines to prevent sweating
and dripping
28. Cont…
2.Machine and room humidity water
The optimum temperature range for humidification
water is above 50°F (10°C). Humidity water lines
should also be insulated to prevent sweating and
dripping.
3. Hatchery sanitation water
Provide both hot and cold water lines for hatchery
cleanup. Hot water temperature should be between
120° and 140°F (49° and 60°C)
These lines should also be insulated
29. Cont…
Pressure
1. Machine cooling water
Pressure should be 40 to 50 PSI (2.8-3.5 kg per square cm)'
at the automatic valves of each setter and hatcher
2. Machine humidity water
Pressure should be 60 to 80 PSI (4.2-5.6 kg per square cm)
at the automatic valves of each setter and hatcher
3. Room humidification water
30 to 40 PSI (2.1-2.8 kg per square cm) is adequate for most
room humidification systems.
The pressure could vary depending on the type of
humidifiers used, therefore, verify the required pressure
with the humidifier manufacturer
30. Cont….
Quality
Water quality can extremely affect the operation, service
life, and required maintenance of hatchery equipment
Using clean water reduces spray nozzle and water line
maintenance, and extends the useful life of boilers, chillers,
ventilation, and high pressure washing systems
If the water supply has a high mineral content, using a
water deionizer, filtration or treatment system may be
advantageous
A neutral pH is preferred since highly acid or alkaline water
supplies can damage equipment
31. Cont
Volume
It is better to oversize than undersize all incoming
water supply lines.
Therefore, size lines based on the simultaneous
operation and combined demand of all applicable
equipment
Also, keep in mind the maximum demand for future
expansion
32. Auxiliary Systems
To support the hatchery, it is necessary to install certain auxiliary
systems
Some common equipment required include
1. Standby generator
2. Hot water boiler
3. Water chiller
4. Disinfectant system
5. Wash-down system
6. Air compressor
7. Waste removal system
8. Transfer window exhaust
9. Alarm System
10. Other items
33. Hatchery Plant Accessories
There are a number of accessories that can provide an extra
measure of safety, efficiency, and convenience to the
hatchery. Common accessories include
Roof access stairways
Machine access ladders
Bumper guards
Rooftop utilities
Eye wash stations
Public address systems
Maintenance and storage items such as spare parts, dock
levelers, and truck wash stations
34. HOW TO MEET YOUR ROOM
REQUIREMENTS
Determine the Hatchery Layout
Chicken hatcheries are divided into three basic types:
broiler, layer, and breeder. Each has unique requirements
that help to determine room sizing and hatchery layout
Arrange the rooms to provide efficient workflow through
the hatchery in the following order: egg room, setter room,
hatcher room, chick room, and bus bay
Auxiliary rooms such as tray wash, clean room, disposal
area, box making, and storage and utility should be
strategically located to support the main work effort
Locate offices, lunchroom, and reception or lobby areas so
they do not interrupt the workflow
35. Conti…
The single most important factor in establishing the
size of the facility is the planned production capacity.
This is important because the size of the egg holding
room, chick room, box storage room, and clean room
are predicated on chick production
Smaller hatcheries usually hatch two days a week, while
larger broiler hatcheries may hatch four or six days per
week to even out the daily workload
Once the daily input of eggs and output of chicks have
been established, the actual room sizes and layout of
the hatchery can be developed
36. Cont…
1. Egg room
Design the egg room to be large enough to provide space for
storing, traying and grading eggs.
A ceiling height of 12 ft (3.65 m) is ideal. The layout of this
room depends on how many eggs are received daily and how
they are received.
Whether the eggs are received in buggies or in egg cases will
affect the room size
Store buggies and egg cases 6 inches (1.5 cm) away from the
wall, with 6 inches (1.5 cm) of space between the buggies or
rows of cases. It imperative to rotate the stock in the egg
room
First in, first out a necessary rule to maintain hatchability
37. Cont…….
1. Egg room
Most hatcheries use buggies that are located at the farm to
eliminate handling in the egg room
With this method, eggs are gathered plastic flats and loaded at
the farm into the buggies. When they arrive by truck at the
hatchery, they are ready for setting.
The maximum number of eggs to be stored at any one time must
be determined before the egg holding room can be designed
Therefore, when calculating egg room size, provide 4 square feet
of floor space for each 1,000 eggs to be stored (0.372 sq m).
The egg room should be large enough to store the setting
requirements for one week
The minimum egg room size should not be less than 600 sq ft
(55.7 sq m)
38. Cont…
2. Fumigation room
Additional space must be provided to fumigate e.g.
cases or holding buggies
Construct the fumigation room large enough so that it
can accommodate one-half of the cases and buggies
used in a single day
39. Cont…
3. Prewarming room
Locate the prewarming room next to the egg room and
make sure that it is large enough to hold one day's
setting of egg buggies
A general rule is to provide 15 sq ft (1.4 sq m) each egg
buggy
It is important to provide airspace around all buggies,
and good air circulation around all eggs to maintain an
even temperature
40. Cont….
4. Setter room
The setter room should be sufficiently large enough to permit
easy access around the setters
Usually 24 to 30 inches (60 to 70 cm) between the ends and backs
of the setters and the walls is considered adequate space for this
purpose
The front of the setter should have a space at least 10 to 12 ft (3.0
to 3.6 m) wide from the front to facing wall or a facing row of
setters
The aisle width will allow for the temporary storage of loaded egg
buggies without interfering with normal work, such as machine
monitoring and maintenance, egg candling and inspection
A good ceiling height for the setter room is 14 ft (4.27 m)
This provides ample room for working and cleaning top of the
setters
41. Cont…
5. Hatcher room
Hatchers must have a front aisle of at least 10 ft (3.05
m)wide
When two rows of hatchers face each other there should be
minimum aisle space of 10 to 12 ft (3.05 to 3.65 m)
If in ovo vaccination is used, provide an aisle width of at
least 12 ft (3.65 m)
Place hatchers 24 to 30 inch (60 to 70 cm) from end and
back walls for cleaning purposes
This allows ample space for a plenum exhaust system, if
wanted
42. Cont…
Only hatchers with the same hatching schedule (same
hatch day) should be located in the same room
As a result, two or more hatcher rooms may be
necessary so that microorganisms released during
hatch will not affect unhatched eggs
Separate hatcher rooms allow takeoff and cleanup in
one room without disrupting machines on a different
hatching schedule
A 14 ft (4.27 m) hatcher room ceiling height provides
ample room for cleaning the tops of the hatchers
43. Cont…. 6. Chick room
The size of the chick room is based on the maximum
number of chicks processed daily
Determine this by dividing the total weekly hatch by the
number of hatch days per week
The extent of processing planned for the chick room will
also affect its required size
Provide adequate space to accommodate all chicks to be
stored in the chick room at any given time
It is also desirable to separate the chick storage or holding
area from the chick service area
Additional space must be included in the design if sexing,
beak trimming, and / or vaccination are planned
Automated chick processing equipment can also affect floor
space requirements.
44. Cont….
Whenever full chick boxes are held in the chick room, always
place them on dollies and stack them at least 12 inches (30 cm)
apart to allow for proper ventilation
When holding chicks in boxes stacked ten high, allow 10 sq ft (9.3
sq m) per 1,000 chicks held
After the storage and processing requirements have been
determined, establish the room size
The requirements generally range from a minimum of 12 sq ft (1.12
sq m) per 1,000 chicks, up to 20 sq ft (1.86 sq m) per 1,000 chicks
Using a hypothetical hatchery with a capacity of 1,663,200 eggs
set per week, on a 4 day per week hatching schedule
The chick room would have to handle approximately 341,000
chicks per hatch
On this schedule, the chick room should be sized at
approximately 4,400 sq ft (409 sq m).

7. Wash room or chick take-off room
Base the room size for this area on the maximum
number of hatcher buggies that will be stored in it at
any one time
Allow space for the tray washer, buggy washer, vacuum
waste system, and any automation equipment
If the wash room has a chick take-off window, a
vacuum or auger system for waste removal should be
located in front of the window
A separate refuse area, usually outside the building, will
be necessary for storage and removal of the waste
46. Cont….
Farm egg buggies will also be washed in this room
The buggy washer should be designed to handle farm
buggies filled with flats
Allow 6 sq ft (0.56 sq m) per 1,000 chicks hatched, or 12
sq ft (1.12 sq m) times the total number of hatcher
buggies per hatch day, plus adequate space for
cleaning, take-off, and automation equipment
47. Cont…..
8. Clean tray room
A clean tray room should be adjacent to the tray wash
room and should hold all the clean trays and buggies
(for one day's hatch) until hatcher rooms have been
cleaned and sanitized
This room should be sized for 15 sq ft (1.4 sq m) for each
buggy stored on hatch day
To reduce workload, locate the tray washer so that
trays can be conveyed directly into the clean room
48. DESIGNING THE HATCHERY
VENTILATION SYSTEM
A. Basic Principles
B. Air Conditioning Units vs Evaporative Cooling
C. Incubator and Hatcher Exhaust Systems
D. Room Ventilation Recommendations
49. A. Basic Principles
Proper hatchery ventilation is important to obtain the
best possible has high quality chicks
Do not rely on natural ventilation
Each room should have its own system for heating,
cooling, and ventilation and controls
Create different pressure different rooms
Air in a hatchery is replenished frequently
50. B. Air Conditioning Units vs
Evaporative Cooling
Incubators (setters and hatchers) are designed to
operate under room conditions where temperature (78°
to 80°F; 26° to 27°C) and relative humidity (from 45 to
55% in the setter room and from 60 to 70% in the
hatcher room)
To control room environments there are two types of
ventilation systems:
the air conditioning combination unit
the evaporative cooling/ heating unit
51. Cont…
In the combination unit, functions of heating and air
conditioning are combined in one packaged unit
In the evaporative cooling/heating unit, the cooling and
heating functions are performed by two different units,
evaporative coolers and makeup air heaters
In cooler climates and seasons, a heating unit(s) is required
to supply tempered air
A roof-mounted heating / make-up air unit is ideal
Caution must be taken to properly balance incoming and
exhaust air supplied by the heating and cooling systems so
as not to disturb the various pressure differences among the
rooms in the hatchery
During heating in dry seasons or climates, a humidification
system is necessary
52. C. Incubator and Hatcher
Exhaust Systems
Air must not be exhausted to the outside not near the
fresh air intakes of the ventilation equipment
Use a mechanical exhaust system to remove the air
from the building.
There are two general types of machine exhaust
systems:
a) exhaust duct
b) exhaust plenums
53. Cont..
a) Exhaust ducts
The main exhaust duct (a relatively large length of duo work) is
normally suspended a few feet over the incubator or hatcher
exhaust thimbles
Smaller branch ducts or drops connect to the main duct and
extend down to within a few inches above the top of the machine
exhaust thimbles
They do not directly connect to the exhaust-thimble on the
machine.
In incubator rooms, the main duct is typically routed up through
the roof to a roof mounted exhaust fan
In hatcher rooms, the main duct should exit through an outside
wall, of the building via a sidewall mounted exhaust fan. In some
case„ there may also be one or more dampers in the main duct to
balance airflow in the system.
54. Cont…..
b) Exhaust plenums
In a plenum system, ductwork is not used to capture
exhaust air from the setters and hatchers
Rather an enclosure (plenum) is erected around the exhaust
end of the machines to capture the discharged air
Doors are installed at both ends of the plenum for easy
access for cleaning
When exhaust plenums are used, the machines will have
rear exhaust thimbles
The typical hatchery using the plenum system will have a
series (bank) of side-by-side hatchers or setters, with all
exhausting into the common enclosure (exhaust plenum)
behind the machines.
55. D. Room Ventilation
Recommendations
As there is specific recommendations for temperature,
relative humidity, and outside air in the principal
hatchery rooms
The ventilation system for each room in the hatchery is
dependent upon outside conditions
56. a) Egg room
The -longer-you store eggs, the colder the room
temperature should be
As the dry-bulb temperature is reduced to adjust for
longer storage times, the relative humidity must be
increased
When eggs are stored at the cooler temperatures, they
are in a state of dormancy
The minimum fresh air requirement is 0.075 cfm per
1,000 eggs (0.13 m3 / hr)
Additional fresh air may be required to maintain a
positive pressure in the room, relative to adjacent areas

Over 7 days 55-57 (11-12) 52-54 (9-11) 80
58. b) Prewarming room
The recommended temperature for this area is 76° to 80°F
(24.4° to 26.7°C)
Relative humidity level below 45%
Under these conditions, the eggs will not sweat as their
internal temperature increases.
The method of prewarming is very important
Allow for free air space around each egg buggy and good air
circulation around all eggs in order to maintain even
temperatures and help evaporate condensation
To provide a gentle and uniform air circulation, horizontal
ceiling fans should be used

60. D.) Chick room
Optimal chick room conditions for holding chicks are
follows:
Temperature: 75° to 85°F (25.6° to 29.4°C)
Relative humidity: 50 to 60%
Chick box store the stacks approximately 1 ft (0.3 m) apart
The fresh air required depends upon the number of chicks
held at any one time and the number of people processing
chicks the room
Following are recommended minimum fresh air
requirements for the chick room:
12 cfm (0.34 cmm) per 1,000 chicks
20 cfm (0.57 cmm) per person
61. e) Wash room
The wash room in most hatcheries is also used as a
chick take-off area. While holding chicks in this area
the following room conditions should be maintained:
Temperature: 78° to 85°F (25.6° to 29.4°C)
Relative humidity: 50 to 60%
Exhaust hoods are required for the chick take-off area,
and the tray washer and buggy washer
62. f). Clean room
The clean room, which is used for drying trays and buggies
when these have been washed, requires large quantities of
fresh air to aid with drying
Adequate fresh air helps to maintain a positive pressure in
this room and prevent the growth of mold and bacteria in
the room and on the washed equipment
With the clean room maintained at a positive pressure with
respect to the wash room, steam vapors and contaminated
air will flow away from clean trays and buggies and toward
the wash room exhaust systems
Inadequate or poorly balanced ventilation systems in the
processing areas can rob air from incubator or hatcher
rooms or cause contamination of clean rooms
