4. that most of our so-called poultry
breeds were developed within the
last 100 years
5. consideration of poultry as a source of meat, rather than just for
egg production, started in the early 1900’s. The term “broiler”
seems to have originated in the eastern USA describing a very
young (10-12 week old) bird which was most often prepared by
splitting the bird longitudinally and “broiling” over an open fire
6. As early as
1900 there are reports of flocks of
5000 broilers grown to 12 weeks of
age for this specific market..
7. as late as 1940 there is often
mention of White Leghorn males
being suitable for broiler
production
8. Barred Rock: Because of its
popularity at Cornell University
and the
University of Guelph, this breed
was promoted as a meat producing
bird
in the early 1900’s. Apart from
having only moderate growth
potential
compared to some other breeds, a
subsequent disadvantage was the
dark pin feathers associated with its
feather color.
9. White Plymouth Rock: Developed
in the New England States in the
1870’s, this breed was to become
the choice for female lines within
most breeding programs. Its main
advantage was white plumage, and
while initially most birds were slow
feathering, this characteristic was
quickly changed to the fast
feathering allele.
10. New Hampshire: Also used on the
female side of early broiler
breeding
programs, the New Hampshire had
reasonable growth characteristics
and good egg production and
hatchability.
11.
12. White Cornish: With white feathers and
yellow skin the White Cornish
offered great potential for establishing
white feathered broilers in the
1920’s - 30’s. With relatively short legs
and a heavy muscled broad breast, the
breed quickly became established as a
major contributor to the male lines within
the breeding programs.
Because of relatively poor
egg production, the Cornish was little used
in female lines of the 3 or 4 way crosses
that were to become the most popular
breeding systems.
13. Light Sussex: More popular in
Europe, the Light Sussex was
somewhat comparable to the New
Hampshire in the USA, in
providing a breed that could be
reasonably well used in either male
or female lines.
14. Over time, the White Cornish male
crossed with the White Plymouth
Rock female became the basis for
most broiler breeding programs. In
addition to being white feathered,
the cross gave an excellent balance
of growth, conformation and
livability together with a
reasonably good
level of reproduction.
15. The modern broiler industry started
in the Delmarva region of the USA
in the mid 1930’s
The Delmarva Peninsula, or simply Delmarva,
is a large peninsula on the East Coast of the
United States, occupied by the vast majority of
the state of Delaware and parts of the Eastern
Shore regions of Maryland and Virginia.
16. New Hampshire also
quickly developed a new broiler
industry, although this New
England
region was soon to become more
important as the location of many
influential primary breeding
companies.
New Hampshire is a state in the New
England region of the northeastern United
States. It is bordered by Massachusetts to
the south, Vermont to the west,
17. Georgia was one of the
first to apply sharecropping
systems to broiler production. As
farms
became larger with 10,000+ birds,
the local feed dealer became the
Industry Development major
source of credit. There was a move
to also supply chicks on
credit, and so there was a natural
development of tying chick and
feed sales together, and this became
the basis for contract production
and
integration within the industry.
18. During World War II, the Delmarva
region accounted for almost 50% of
the chicken meat production in the
USA, with much of this contracted
to the government.
20. virtually all selection for heritable
traits has been accomplished by the
primary breeding company. For
grandparents and parent stock, we
have only to select birds based on
their phenotype for such traits as
skeletal integrity morbidity
21. The breeding of broiler chickens
ultimately comes down to gradual
multiplication of the generations
necessary to meet the ever
increasing demands for broiler
meat production.
22. Each generation results in
multiplication of bird numbers
by factors of about 50 or 100
depending on whether one or both
sexes are needed.
23. Within a few generations, pure bred
stock measured in just
hundreds of birds quickly evolve
into commercial broilers measured
in hundreds of millions.
