Title: Understanding Organismic Biotechnology


1
Lesson 6
  • Understanding Organismic Biotechnology

2
Next Generation Science/Common Core Standards
Addressed!
  • HS-LS4-6. Create or revise a simulation to test a
    solution to mitigate adverse impacts of human
    activity on odiversity. Clarification
    Statement Emphasis is on designing solutions for
    a proposed problem related to threatened or
    endangered species, or to genetic variation of
    organisms for multiple species.
  • WHST.9-12.7 Conduct short as well as more
    sustained research projects to answer a question
    (including a self generated question) or solve a
    problem narrow or broaden the inquiry when
    appropriate synthesize multiple sources on the
    subject, demonstrating understanding of the
    subject under investigation. (HSLS1-3)

3
Work!
  • 1. Identify the major areas of biotechnology in
    animal science.
  • 2. Discuss applications of organismic
    biotechnology.

4
Terms
  • Animal biotechnology
  • Biotechnology
  • Embryo transfer
  • Molecular biotechnology
  • Organismic biotechnology
  • Super ovulation

5
Interest Approach
  • Is biotechnology safe?
  • What are some practices done by animal producers
    every day that are a form of biotechnology?

6
What are the major areas of biotechnology in
animal science?
  • I. Biotechnology is the management of biological
    systems for the benefit of people and their
    environment. It is also viewed as the application
    of science in food and fiber production.
  • Animal biotechnology is the application of
    biotechnology methods to improve animals.

7
  • Biotechnology has been used for hundreds of
    years. Using yeast to make bread and bacteria to
    make cheese are everyday examples of
    biotechnology.

8
  • There are two major areas of biotechnology in
    animal science
  • A. Molecular biotechnology
  • B. Organismic biotechnology

9
  • Molecular biotechnology is changing the structure
    and parts of cells to change the organism. It
    begins with the atom.
  • Molecular biotechnology often changes the
    physical appearance of an organism.
  • In some cases, undesirable traits may develop
    along with those that are desired.

10
  • Organismic biotechnology deals with intact or
    complete organisms.
  • The genetic makeup of the organism is not
    artificially changed.
  • This is the most widely used type of
    biotechnology.

11
What are some applications of organismic
biotechnology?
  • Most animal management practices done in
    livestock production are organismic
    biotechnology. Several examples of this area of
    biotechnology are from
  • A. Greater Fertility
  • B. Increased Production

12
  • Greater fertilityIncreasing the reproductive
    capacity of top animals is important to
    producers.
  • Two methods to increase the reproductive capacity
    of animals are

13
  • Super ovulation is getting a female to release
    more than the usual number of eggs during a
    single estrous cycle.
  • Hormones are injected to assure more eggs.

14
  • Embryo transfer is taking an embryo from its
    mother and implanting it in another female.
  • The embryo completes development in the recipient.

15
  • B. Increased productionThree methods used to
    increase production are

16
  • 1. Milk hormonesInjections of milk hormones
    cause the cows mammary system to become more
    productive.
  • The most common milk hormone is bovine
    somatotropin (bST). Since bST is a naturally
    occurring hormone, it has been widely accepted in
    the dairy industry. Some areas of the country
    limit the use of bST due public concerns.

17
  • 2. Meat hormonesInjections of meat hormones
    causes the animal to produce more muscle cells
    resulting in larger and leaner cuts of valuable
    meat. This process actually began in cattle
    feedlots in the 1960s.

18
  • 3. Growth implantsGrowth implants are small
    pellets placed under the skin.
  • They promote growth by making the animal more
    feed efficient.

19
Enhancing animal nutritionThe greatest results
of biotechnology have been seen in animal
nutrition.
20
Some of the enhancements are
  • 2. Controlled feedingComputer chips can be put
    in a monitor around the animals neck, ear tag or
    under the skin.
  • A computerized feeding station will read the
    chip regulate the amount of feed the animal
    receives. Use quite a lot in the dairy industry
    to regulate grain fed during milking.
  • Daily feed intake is used to aid in the detection
    of health problems.
  • 1. Digestibility testingTests are made by
    getting samples from the digestive systems
    ofanimals after they have eaten. This
    information is used to improve feed use and
    animalgrowth.

Review/ Summary
  • 1. What are some of the major areas of
    biotechnology in animal science?
  • 2. What are some of the applications of
    organismic biotechnology?
