Ostrich Hatchery Requirements
.
Hatchery
Hatchery is a machine which provides the basic
requirement for the development of embryo into a
health chick
.
Oology
The branch of science which deal with the study of eggs is
known as Oology
EggA chamber that provides
nourishment and protection for the growth and
development of embryo inside it
.
Embryo The earliest development of
germinal disk within egg until it hatches
.
Germinal disk
A small, circular, white patch on the upper surface of yolk, containing cell from which
the chick develops if the egg is fertilized
Incubation Periods of Avian Species . 1 Hen 21 Days
2 Quail 21-23
3 Duck 28
4 Turkey 28
5 Ostrich 35-49
Incubation Methods Natural Incubation Artifical Incubation
Natural Incubation For small scale household purpose Required by Medium Size ostrich
Characterized by Ruffled feathers
Loosing feathers under wing & legs Free from parasite (External & Internal)
Capacity of eggs 15-20 eggs/ ostrich Clean nesting material

Setter Hatcher
Setter
From 1-38 days Broader end up & Pointer end at bottom Turning automatically--------4-6 times It has multiple trays Ventilators for Ventilations Heat source –electricity with fans for uniform distribution

Temperature
Setter 36.5
Hatcher36
Effect of High Temperature
smaller / weak chick
unhealed naval
missing eyes & brain
Effect of Low Temperature
delayed chicks
sticky chicks
Humidity %age of moisture in air
Setter 14-20
Hatcher30-35
Effect of High Humidity
less evaporation
hatching delayed
soft abdomen chicks
Effect of Low Humidity
excess loss of water
early hatching
dehydrated chicks
Ventilation Crossing of fresh gasses with foul gasses
Normal Co2 level-------0.3%Above 0.5%-----------reduced hatchability Above 2%-------------0% hatchability
Altitude High altitude – reduced hatchability Normal hatchability is –50-70%
At 2500 ft--------85% At 4950 ft--------74% At 7160 ft--------64%
Recommended sea level –2500 ft
Position of eggs
Position of egg is Broader end up & Pointer end at bottom
If broader end at bottom 50% dead in seal due to non-establishment of pulmonary respiration
Turning of eggs Normal turning angel 40-45o each side 4-6 times turning / 24 hours If turning in circle it will rapture allantois membrane
Normal turning provides uniform temperature reduce sticky chicks
50% dead in shell due to non-establishment of pulmonary respiration
