Clone on the range: Meat from four clones of a Japanese Black beef bull and milk from cloned cows meet industry standards
Meat and milk from cloned animals have met industry standards in a pilot study addressing their potential as a food source.
Xiangzhong Yang of the University of Connecticut and colleagues cloned a Japanese Black beef bull and Holstein dairy cow using somatic cell nuclear transfer, the technique used to create Dolly.
The researchers then compared the meat and milk from the clones to that of matched animals bred through natural reproduction.
Based on an evaluation of protein, fat and other factors regularly assessed in the dairy industry, Yang and colleagues found no significant differences in milk.
On 100 meat quality criteria, 90% showed no noteworthy variations. Meat from the cloned animals was found higher on about eight variables related to fat and fatty acids, but the researchers say that these still fall within beef industry standards.
The report provides more information for determining whether products of cloned animals should enter the food chain.
In August 2002, the US National Academy of Sciences concluded that food from cloned animals should be considered safe if no genetic manipulation was involved, and government organizations in several countries, including the US and Japan, have already—if tentatively—said that food from cloned animals is safe.
The new research is reported in the Proceedings of the National Academy of Sciences (read abstract).
