Animal Cloning

In 2001, when the cloning of animals became a commercial enterprise that obviously helps to improve the quality of herds, the FDA will not allow livestock producers and researchers to remove animals from cloning animals or descendants I requested it. Since that time, the FDA made a thorough evaluation, including testing food safety and animal health risks of these animals.

Based on the final risk assessment that was written by FDA scientists and published in January 2008, the FDA says meat and milk from cattle, pigs, goat clones and descendants of animal clones every day food to eat I concluded that it is like. safety

The answers to the questions provided in this document represent the FDA's views based on the conclusions and recommendations outlined in the "Animal Cloning Risk Assessment", "Risk Management Program" and "Industry Guide # 179" .

In this document we address the health risks of animals related to cloning and the safety of cloned foods and take action within the mandate of the authorities to control the risks associated with the cloning of animals I will. Products are used for human food and animal feed. No Like other calves, calves do not require special treatment. For example, depending on the region, rendering may be an option. The US Food and Drug Administration (FDA) policy on the use of dead cattle in animal clones for animal feed is the same as other dead cattle. For more information on the use of extract products in animal feed please refer to the compliance policy guide 7162.24 entitled "Rendering animal feed material".

Animal cloning is a way to produce multiple copies of a single animal. There are many forms of cloning animals. The latest and most commonly used technique is called somatic cell nuclear transplantation. It involves removing the nucleus from the egg or oocyte (receptor) and replacing it with nuclei from the animal (donor) to be cloned. The donor is usually an animal with the desired trait, and after successful transplantation the cells grow into embryos, which are transplanted for feeding to surrogate mothers. Animals born from this embryo will have nearly the same DNA and therefore will have the same ideal characteristics as donor animals.

Animal cloning: During somatic cell nuclear transfer, scientists collect cells from cloned animals (called "genetic donors"). Somatic cells contain DNA from genetic donor animals. Scientists collect eggs from female animals ("egg donors") and discard the nucleus of egg cells, which is part of the cell containing the egg donor gene. Then the scientist inserts the somatic cells into the egg. The resulting fused egg contains the DNA of the genetic donor. We transfer fused eggs to substitute mothers and continue their development. After full term pregnancy, the birth of the recipient is normal, the animals are basically the same twin genetic donor.
