Title: Animal SCience

Animal SCience
What is Animal Science?
  • Study of the principles of animal nutrition,
    physiology, genetics, health, behavior, products
    and production systems.
  • Why do we raise animals?
  • - Enjoyment
  • - Use / Work
  • - To make money

Animal Industry???
  • All of the activities involved in raising animals
    and meeting the needs of the people for animals
    and animal uses
  • Livestock
  • Are animals produced on farms and ranches for
    food or other purposes.
  • Ex. Beef, Pork, Chicken, Turkey, Eggs Clothing

Relative contribution of the major meat species
to world meat supplies.
Per capita meat supply in pounds, selected

Figure 3 US Net Exports of Red Meat and Poultry
(Carcass Eqivalent, Million Pounds)
How does the Animal Industry impact the United
States Fiscally ?
  • - Agriculture is 17.5 of the GNP in the United
  • - The largest segment of the US economy
  • - 50 Crops, 50 Animal Agriculture

Animal Terminology
  • Animal domestication
  • taking animals from nature and raising them in a
    controlled environment. ( taming wild animals
    to be raised by humans)
  • Animal Selection
  • choosing animals to achieve desired goals.
  • Nutrition
  • the study of the kind food an animal eats and
    how it is used by the animal
  • Ration
  • the animals diet. What is consumed each day.

Animal Classification Terminology
  • Animals are classified and named by
  • Neutering-
  • are animals that are altered sexually
  • Why is this done?
  • Castration-
  • the removal of the testicles
  • Spaying-
  • removal of the ovaries or cutting the fallopian

Scientific Method
  • Ask a Question Describe a problem
  • Do Background Research
  • Construct a Hypothesis
  • Test Your Hypothesis by Doing an Experiment
  • Analyze Your Data and Draw a Conclusion
  • Communicate Your Results

Animal Physiology
  • Internal functions and vital process of animals
    and their organs
  • 8 Categories
  • 1. Skeletal System -
  • Bones which provides support for the body
    and protection of organs.
  • 2. Muscular System
  • Provides movement in cooperation with skeletal
    system and to support life.

Animal Physiology
  • There are two types of muscles
  • A. Voluntary muscles- can be controlled by
    animals to do things such as walking
  • B. Involuntary muscles operate in the body
    without control by the will of the animal.
  • 3. Circulatory System-
  • Heart, veins arteries and lymph glands these
    provide food, oxygen to cells of the body and
    filters waste materials from the body

Animal Physiology
  • 4. Respiratory System-
  • Provides oxygen to the blood of the animal
  • Allows for breathing through
  • Nostrils, nasal cavity pharynx, larynx, trachea
    and lungs.
  • 5. Nervous system-
  • Central Nervous System Spinal cord and brain
  • Coordinates movement and allows the sense of
    hearing, sight, smell, touch and taste
  • Peripheral nervous System controls body tissues
    including the organs transmits messages from
    brain to outer parts of the body

Animal Physiology
  • 6. Urinary system
  • Remove waste materials from the blood
  • Parts include- kidneys, bladder and urethra
  • 7. Endocrine System (Hormone system)
  • These are ductless glands that release hormones
    into the body
  • Hormones are chemicals that the body makes to
    regulate growth, reproduction, milk production,
    and breathing rate

Animal Physiology
  • 8. Digestive System
  • Provides food for the body and for all of its
  • This temporarily stores food for use b the body
    and removes the waste products from the body.
  • There are 3 basic types of digestive systems
  • A. Ruminant
  • B. Monogastric
  • C. Poultry
  • Animals on the farm can be classified as either
    ruminant and non ruminant.
