Let’s talk about Dolly
   1st cloned animal
   Only one born alive
   Died prematurely

        Cloned farm animals


One of the first cloned horses
       More cloned animals                                           Afghan hound with his clone
                                                                     “Snuppy”

Problems with cloning
   Die before birth
   Born alive and suffer from serious
    abnormalities
   Premature death
   High birth weights
   Inefficiency
Other views against cloning
   Stephanie Shain of the Human Society
        “It’s irresponsible to duplicate animals when we are euthanizing happy, healthy
         animals because there aren’t homes for them.”


   Brent Blackwelder, President, Friends of the Earth
    and Wayne Pacelle, Senior Vice President, The Humane Society
Prices
   Horses $150,000
       Cloned horses
        cannot be registered
   Cattle $15,000
       Majority can be
        registered
   Not always a foal or
    calf born alive.
   Inefficiency
Cyagra says cloning can…
   Help keep up with the demand for semen,
    embryos, and offspring
   Repair injured cattle
   Have multiple copies of top performing bulls
   Bring great steers back as bull
   Bring free-martins back as reproductively sound
    heifers
   Build a foundation herd
   Speed up the genetic program
What does Viagen say?
   More affordable protein
   More sustainable farming
   Higher quality products
   More environmentally friendly
   Animal welfare friendly
   Healthier animals before antibiotics
   Completely safe
   Easily implemented
   Says that most of the meat we eat in the future
    will be from cloned animals.
I don’t agree
   Cattle
   Swine
   Equine
FDA
   FDA has sent out an
    assessment whether
    companies and
    American consumers
    agree with eating
    cloned meat or
    believe it is safe to
    eat.

     Call to Action…
        Stay informed
        Challenge you to go to
         legislation
