An HSUS Report: Welfare Issues with Genetic Engineering and Cloning of Farm Animals
Developments in biotechnology have raised new concerns about animal welfare, as farm animals now have their genomes modified (genetically engineered) or copied (cloned) to propagate certain traits useful to agribusiness, such as meat yield or feed conversion. These animals have been found to suffer from unusually high rates of birth defects, disabilities, and premature death. In the United States, there is significant public opposition to the introduction of meat and milk from cloned animals and their progeny into the food supply and currently no regulations exist to protect the welfare of farm animals during cloning or genetic engineering agricultural research.
