Pre–Brooding
Managemental practices beforebrooding or before receiving the chicks
PurposeTo avoid the stress on the birds
For the sanitation and disinfection
Expose surface to the disinfectant andfumigants
Remove material that helps in multiplicationof pathogens
To avoid different diseases

Following measures are generally consideredfor taking good results1. Selection of area2. Cleaning3. Removal of litter4. Clean the equipment5. Dusting/web removal6. Repairing7. White Washing8. Disinfection9. Fumigation10. Provision of different materials11. Equipment testing12. Arrival of chicks

BROODING MANAGEMENT
Special care and management of babychicks until they do not require artificialheat is called brooding
Types
1. Colony brooding system
2. Continuous brooding system
![Page 7: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/7.jpg)
Brooding
NATURAL ARTIFICIAL
![Page 8: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/8.jpg)
MANAGEMENT FACTORS THAT WILL RESULT TOUNEVENNESS
1. Cold stress during the 1st week
2. Inadequate pre-heating of houses
3. Draughts
4. Low temperature settings on heaters orinadequate heaters
5. Mixing of DOCs from different DOC sources(breeds and ages of Parent Stocks)
6. Inadequate litter and/or dampness under the litter
![Page 9: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/9.jpg)
MANAGEMENT FACTORS THAT WILL RESULT TOUNEVENNESS
7. Overcrowding (delayed floor spaceexpansion)
8. Poor cleaning and disinfection prior toplacement
9. Insufficient equipment to bird ratio andincorrect positioning of equipments. Placeequipments where the birds are.
10.Feeding mismanagement

Colony Brooding System
In this, individual brooders with thecapacity of 300-400 chicks are placed inhouse
Heat is provided with oil, coal, wood, gas orelectricity
They are of different typesi Drum typeii. Coal burningiii. Wood burningiv. Electric brooderv. Gas brooder
![Page 11: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/11.jpg)
Continuous Brooding System
Large numbers of chicks are brooded at a timein a single house
Hot water or air heat the brooder room Different methods are1. Hover Method2. Warm Air Brooding3. Warm Room Method4. Warm Pad Brooder5. Radiant Heat or Heated Floor Brooding6. Batten Brooding7. Tier Brooding
![Page 12: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/12.jpg)
CORRECT BROODINGMANAGEMENT
1. Clean Environment2. Pre – Heating = Minimum – 1 hour before chick
placement = 36 to 40 0 C at floor level. Optimum LPGconsumption in tunnel ventilated houses should notbe less than 18 kgs/K birds in 10 – 12 days.
3. Correct Height of Heaters is 3 feet at placement thenraise to 3.5 to 4 feet at 1st expansion.
4. Correct Curtain Management5. Litter management – To attain adequate thickness,
requirement is ½ bag of rice hulls/square meter. Itmust be dry but not dusty. Prevent/minimizewetness/caking
6. No tunnel ventilation please.

DIFFERENT MANAGEMENTALPRACTICES DURING BROODING1. Litter and paper materials2. Chick Guard3. Proper floor space4. Temperature and lighting5. Ventilation6. Humidity7. Sanitation8. Flushing and supplements9. Feeding and drinking10. Broad spectrum Antibiotics11. Vaccination12. Debeaking13. Avoid predators and pilfering14. Weighing

The Aim Of Brooding
The general concept is to accelerate growth rate in
the first week (TO GAIN 4 TIMES THE INITIAL
CHICK WEIGHT) to enhance structural
development and feed capacity intake.
Allow good development of internal organs.
Encourage early uniformity.
Add to maximize genetic potential.
To improve overall health of the bird (ALLOW
ABSORPTION OF YOLK WITHIN 3 – 4 DAYS).
![Page 22: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/22.jpg)
Immune system is developing.
Maternal antibodies in yolk.
Temperature regulation is notcompletely functional.
Low air temp = low body temp
• Feed conversion is most efficient7d = less than 0.94
14d = less than 1.27
Brooding Phase (1-14 days)
![Page 23: Pre –brooding, brooding and rearing management of chicks](https://reader031.fdocuments.in/reader031/viewer/2022012315/55a62b021a28abd0138b484c/html5/thumbnails/23.jpg)
Check Crop Fill Check if chick boxes have traces of feeds.
4 hours after placement, at least 90 % of thechicks should have feeds and water in their crop
8 hours after placement, all chicks should havefeeds and water in their crop.
Crop when felt should not be too hard or too soft, itshould have a doughy feeling.

2 Day Old
Introduce adult feeders and waterers as early as possible.These equipments should be placed where the chicks areMake them as hurdles so that birds can find them easily.

Rearing Management
Brooding up to sexual maturity of the birds
The performance of laying birds dependsupon the efficient management during thiscritical period, regarding housing, feeding,watering, temperature, ventilation,sanitation, lighting and disease control
Poor quality pullets at maturity will alwaysperform below breed’s standard of eggproduction, egg quality, feed conversionand size of egg.
