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
