Does Cloning Have An Effect on the Animals?
When an animal is cloned, both the sick and deformed clones and their surrogate parents are put through unneeded suffering. The cloned animals have more problems during childbirth. This causes higher rates of spontaneous abortion and death among host mothers. Severe physical deformities cloned animals have been noted by scientists. Some of these deformities include: over-sized navels, oddly-shaped heads, immune deficiencies, diabetes, heart and lung damage, kidney failure, brain irregularities, and malformed arteries. The cloning success rates in 2007 were as low as 10 percent.
If a cloned animal does survive and make it through their first six months of life, the FDA states that the animal is healthy. Although the FDA states the animal is healthy, problems with cloned animals occurred up to 15 month of age. If cloning animals for food, the animal should be in its healthiest state.
The long-term animal, human, and environmental health impacts of breeding programs based on clones remain unknown. The programs do show a direct opposition to the principals of the Precautionary Principle. The Precautionary Principle proposes that new technology will be proven safe before it is widely introduced.
