The Poultry Industry:
 Early Poultry Production
o First poultry raised was more than 5000 years
ago in Asia and in Egypt about 3500 years ago.
o Poultry was brought to North America in 1607
o Turkeys were native to North America
Modern Poultry Industry:
 Confinement
 Leading states for meat production: Georgia,
Arkansas, Mississippi, Alabama, and North
Carolina
 Leading state for egg production: California
 Leading states for turkey production: North
Carolina, Minnesota, and California.
 Poultry Science – the study and use of areas of
science in raising poultry.
 Vertical integration – more than one step in the
poultry process ( chick and
feed/growers/broilers/buyers)
Poultry as Organisms:
 Classified as Aves
 Vertebrates
 Differ in digestion and reproduction
 Digestion – beak and gizzard
5
 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.
Poultry Production Systems:
 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 and Equipment:
 Housing – Controlled environment.
o Litter – wood shavings
6
o Lighting – control laying cycle (14 – 16 hours)
and cannibalism (red light).
o Temperature – 85 – 95 degrees F for babies, 70
for 6 week birds
o Humidity – 50 -75 % in broiler houses. Mist
systems are used.
o Ventilation – using large fans. Helps prevent
cannibalism.
Feeding and Watering Equipment:
 Automated equipment is used
Sanitation:
 Use disinfectants
 Vaccinate
 Dispose of dead birds in an incinerator
 Diseases – mostly caused by a bacteria or virus
o Marek’s Disease – virus - paralysis of legs and
wings.
o Newcastle – Virus – soft eggs, affects birds
gasp, twist neck around.
o Infectious Bronchitis – virus – nasal discharge,
laying stops.
o Fowl Cholera – bacteria – fever, colored heads,
death.
 Parasites –
o Coccidiosis – parasite – droppings get into food
or water. Birds are sleepy, pale and listless.
7
o Large Roundworms – worm – 3 inch worms,
picked up in soil. Deworm.
o Mites – mite – use insecticides. Bird is pale,
droopy and listless.
o Tapeworm – Worm – Bird pale, looses weight.
