Poultry in U.S. Agriculture

  • Combined gross annual income: over 45 billion.
  • Second-largest sector of animal agriculture.
  • Poultry and eggs farm cash receipts: 23\% of animals
  • Three major segments:
    • Broilers
    • Eggs
    • Turkeys
  • Broiler production has steadily increased since 1975.
  • Lower-cost product than other meat-producing industries.
  • The United States:
    • Produces 8\% of the world’s chicken eggs and 18\% of the chicken meat.
    • Largest poultry meat-producing country in the world.
    • Second to China in chicken egg production.
    • Produces 47\% of the world’s turkey meat.
    • Largest producer of turkeys in the world.
  • More than 90 billion eggs annually:
    • 70\% are consumed as fresh-shell eggs.
    • Rest is used to make cakes, pies, pasta…
  • Duck: the largest of the remaining segments primarily for meat.
  • Geese are raised throughout the U.S. in hobbyist or farm flocks.
  • Game birds and other exotic fowl are usually kept either for exhibition or ornamental reasons or for meat production.

Purpose in U.S.

  • Inexpensive meat production.
  • Very efficient monogastric converting grain to meat.
  • Mainly economical by reducing labor and time to market:
    • Expensive confinement facilities.
    • Full feeding of high-energy rations.
  • Poultry meat and eggs account for nearly 1.6 times as much product as pork and nearly 2.9 times as much as beef.
  • Also used for:
    • Pharmaceuticals production.
    • Vaccine production.
    • Research.

Structure of the Poultry Industry

The U.S. Broiler Industry

  • Meat chickens are marketed primarily as broilers (6-8 weeks), roasters (8-12+ weeks), or game hens (4-6 weeks).
  • Modern broiler production is concentrated in a relatively few large farms with large investments in facilities.
  • Highly integrated corporate industry.
  • All segments are either owned or controlled by the parent company.
  • Well over 90\% of the commercial broilers in the United States are grown under contract to an integrated broiler firm.
  • Top ten largest vertically integrated chicken producers in America
  • The industry located and developed in these areas initially for three reasons:
    • Favorable climate that reduced housing costs
    • Low-cost labor, which was often the small farmer who worked off the farm as well as on the farm
    • Nearby population centers that provided a demand for the product.
  • Southern and Southeastern centered

The U.S. Egg Industry

  • Large units that require large capital investments.
  • Environmentally controlled housing and computer technology are common: never touched!
  • Most production is integrated from hatchery to marketing of the eggs.
  • The poultry egg industry is distributed in a pattern much like that of the human population.
  • The average number of laying hens and pullets in the United States is about 350 million birds.
  • Total U.S. egg production is about 97 billion eggs.
  • That’s an approximate increase of one egg per hen per year.

The U.S. Turkey Industry

  • Most production units grow from 50,000 to 75,000 birds and have approximately 3.5 grow-out cycles per year.
  • Large facilities often have a single brooding complex that serves multiple grow-out facilities.
  • Virtually all turkeys are produced on contract to an integrator.
  • Turkey hens are marketed between 14 and 16 weeks of age and from 14–18 lbs.
  • Toms are marketed between 17 and 20 weeks of age and from 26–32 lbs.
  • Mostly processed further.

Genetic & Breeding Programs

  • Breeding and selection of poultry differs from breeding of the larger animals in three major ways:
    • it is more flexible because of short generation intervals and large numbers of offspring;
    • it has been the industry most subjected to modern animal breeding and selection techniques and has made the most progress;
    • fewer people make all the decisions.
  • Favored traits are quantitative traits such as:
    • egg production potential,
    • egg size,
    • growth rate,
    • conformation.
  • Traits showing favorable heterosis (hybrid vigor) include egg production, egg weight, body weight, and age at reproductive maturity (days to first egg).
  • Breeding:
    • Inbreeding is frequently used.
    • Outcrossing is the term used in poultry for crossbreeding.
    • Poultry breeding is handled in an extremely controlled manner with fewer than 100 breeding programs.
  • Breeds, varieties, and strains:
    • Generally speaking, chickens are one of two types: meat type or egg type.
    • Chickens exist in many colors, sizes, and shapes and in more than 350 combinations of these traits.
    • To identify and classify the species, they are designated by class, breed, variety, and strain.
      • Group of breeds from the same area Specific set of physical features
      • Subdivisions of breeds Based on feather color, comb type, and presence of a beard and muffs.
      • Families more alike than variety
    • Commercial poultry industry is based primarily on strains and strain crosses.
    • The American Standard of Perfection is a compilation of the breed standards.
    • Single Comb White Leghorn: most numerous
    • Single Comb Rhode Island Red
    • Barred Plymouth Rock
    • New Hampshire and White Plymouth Rock were and still are, used to develop many of the synthetic lines of meat-type chickens.
    • Cornish is an excellent meat-producing chicken – found in all broilers
  • Turkey Breeds
    • Descendant of the wild turkeys native to North and Central.
    • The ASP lists 8 varieties of turkeys, including 7 developed in the U.S.
    • Large White, Medium White, Small White, and Bronze varieties are generally offered; the Large Whites have come to dominate the industry.
  • Duck Breeds
    • Mallard: most popular duck in U.S.
    • White Pekin: major duck of commercial importance in U.S.
  • Geese Breeds
    • The domestic goose, which was bred in ancient Egypt, China, and India, is said to have been in the United States since early colonial days.
    • The White Emden and Toulouse are the two most popular goose breeds.
    • The African, Pilgrim, and White Chinese are also raised in significant numbers.

Reproductive Management

  • Breeder Flock Management
    • Selected to be healthy and free of defects that can interfere with proper mating and egg production.
    • Males should be aggressive and willing to breed.
    • Females should be selected for good egg-laying traits.
  • Mating Systems
    • Mass mating—several males are allowed to run with a flock of females.
    • Pen mating—one male is mated with a small flock of females.
    • Stud mating—one female is mated with one male.
    • Artificial insemination—commonly used in turkey production.
  • Selection and Care of Eggs
    • Frequent collection of eggs is important.
    • Eggs laid on the floor or that are dirty should not be used because they spread disease.
    • Hatching eggs cannot be washed because it removes the protective sealing substance from the shell, allowing bacteria to enter the egg.
    • Commercial operations fumigate eggs prior to setting to reduce the bacteria on the shells and increase hatchability.
  • Egg Storage
    • Stored near 60°F and 75\% humidity to prevent delayed embryo growth and prevent moisture loss.
  • Incubators
    • Proper care must be given to relative humidity, temperature fluctuations, ventilation, and other factors to ensure a good hatch.
    • Eggs must be regularly turned to prevent the embryos from sticking to the sides of the shells.
  • Testing for Fertility
    • Candling at 4–7 days of incubation.
    • Infertile refers to an unfertilized egg or an egg that started developing but died before growth could be detected.
    • Dead germs are embryos that died after growing large enough to be seen when candled.

Nutrition

  • Poultry nutrition is more critical, complicated, and thus a greater challenge to the producer because poultry have:
    • more rapid digestion,
    • higher metabolic rates,
    • faster respiration and circulation,
    • higher body temperature (107°F).
  • Monogastric omnivores and have a specialized avian tract.
  • Paired ceca that develop to digest fiber if fed forages.
  • Poultry and swine generally compete for the same feedstuffs: concentrated feeds such as grains, soybean meal, and by-product feeds.
  • Feed is the largest cost in production of the poultry species.
  • Commercial poultry rations are formulated with the use of least-cost ration formulation programs for fast growth.
  • Poultry species are fed almost exclusively on complete mixed diets that are offered in mash or pelleted (less waste) form.

Health

  • Concentrated and confined production outbreaks cost millions of lives and huge economic losses=
  • Biosecurity measures are routinely practiced
  • Rickets
    • Abnormal bone development due to dietary calcium or phosphorus deficiency or as a result of inadequate vitamin D intake.
    • When young birds are affected, they will have stiff gaits, enlarged joints, and stunted growth.
    • Laying hens with calcium deficiency will produce thin- shelled eggs with low hatchability, followed by decreased egg production.
  • Newcastle Disease
    • Contagious infection caused by virulent Newcastle disease virus
    • Signs of respiratory disease
  • Marek’s Disease
    • Viral infection
    • Highly contagious and easily transmitted

What Influences This Industry?

  • Low cost Fast Food
    • Fast-food chicken is available in virtually every fast-food restaurant and even in gas stations.
  • Nutrition and Health Consciousness
    • Poultry products are nutritious, are often leaner than alternative meats, and have gained the status of a health-conscious food.
  • Cholesterol
  • Natural and Organic Production
  • Food Safety Concerns
  • Technological Innovation and Standardization
  • Animal Welfare
