2. Selection of day old chicks
A healthy breeding stock should be maintain in the hatchery.
Generally 10% of the chicks are not in required body
conditions.
Should remove bad chicks : culling
Culling is based on
- appearance
- behavior of the chicks
3. Characteristics of healthy chick
Rounded head
Active with bright eyes widely open
Strong, straight and shiny shins
Without physical defects
No pathogens and with good maternal immunity
Prominent and strong beak
4. Transporting
Within first 3 days.
Specially prepared cardboard boxes with Ventilation facilities.
Avoid over crowding.
Before arrival practices
Disinfection of cages – before 7 days
• Lime (CaCo3) Lysol
Preparation of brooder
Maintain foot bath – before 1 day
5. Management of chicks after arrival
• Should apply paper on the litter material
of brooder before move chicks
• First day provide chick guard for reduce
travel stress condition
6. Brooding
The process of development of day old chicks to independent bird.
In a brooding system,
Chicks reared on litter
Litter is cover using news papers
Change news papers twice a day
8. Feed management
• Normally feed with starter mash
• Content
Crude protein 21-22%
Metabolic energy 2.9 kcal/g
Crude fiber <6%
Ca 1%
P 0.6%
Adequate essential amino acids – Lysine + Methionine
9. • Use feeding tray or chick feeders to feeding
• Use waters to watering
10. Environment conditions
Temperature management
In first week – 32-35°C
Heating must start 24 hours before chicks arrive.
Chick behavior use as a temperature management guide.
Low heat ????
Excess heat ???
Correct heat ???
11. Low temperature cause to
Reduced growth
High temperature cause to
Fainting
Diarrhoea
Reduced growth
Cannibalism
12. Ventilation
Supply fresh air
Remove CO2
Keep litter dry
Relative humidity
60 - 70 % is desired
High RH : make the litter wet and liberate ammonia
Low RH : poor feather development and high death
rate
13. Disease and Vaccination
The modern broiler reaches slaughter weight within
several weeks.
This leaves little time to develop a immune system.
Therefore, broiler chicks are vaccinated against several
diseases.
Vaccines are delivered via spraying or via drinking water.
14. Vaccination
0 day at hatch Marek’s disease vaccine
