Early Poultry Production
 First poultry raised was

ago.
 Poultry was brought to
North America in 1607
 Turkeys were native to
North America

Raised in Confinement
Leading states for meat production: Georgia,

Poultry Science – the study and use of areas of
science in raising poultry.
Vertical integration – more than one step in the
poultry process
(chick/feed/growers/broilers/buyers)


Classified as Aves
Vertebrates
Differ in digestion and reproduction
Digestion – beak and gizzard
Reproduction – eggs are hatched, 21 days
(chickens) 29-31 days (geese) Turkeys (27-28
days) and ducks (28-35 days). Incubation period
is influenced by temperature and humidity.
Appearance – yellow pigmentation – egg
production. Large red comb – good health.
Ragged feathers – poor health.

4 areas:
 Broiler Production – 6 weeks to raise
 Egg Production – 24 weeks to raise




Egg Quality: 95% marketed are white
Parts: Shell, Albumen, Yolk, Membrane
Judging eggs – Candling
Molting – Process of shedding and renewing
feathers. Laying eggs stops during molting. Takes
about 2 months to have a bird completely molt out.
 Pullet for egg Production
 Pullets begin to lay eggs at 24 weeks.
 Pullet and Cockerel for broiler egg production.
 One cockerel per 8-10 pullets

Housing – Controlled environment.
 Litter – wood shavings
 Lighting – control laying cycle (14 – 16
hours) and cannibalism (red light).
 Temperature – 85 – 95 degrees F for babies,
70 for 6 week birds
 Humidity – 50 -75 % in broiler houses. Mist
systems are used.
 Ventilation – using large fans. Helps
prevent cannibalism.
 Automated equipment is used
