In the study, researchers from the University of Connecticut in the US and the Kagoshima Prefectural Cattle Breeding Development Institute in Japan cloned a Japanese black beef bull and Holstein dairy cow using somatic cell nuclear transfer, the same technique used to clone the sheep Dolly in year 1996, says Xinhua.
They compared the meat and milk from the clones to that of animals of similar age, genetics, and breed created through natural reproduction. Analysis of protein, fat, and other variables routinely assessed by the dairy industry revealed no significant differences in the milk.
"In this study, we conducted extensive comparisons of the composition of milk and meat from somatic cloned animals to those from naturally reproduced comparator animals," said Xiangzhong Yang who led the study.
"We found no significant differences between clones and their controls, and all parameters examined for the clones in this study were within the normal range of beef and dairy products approved for human consumption."
There has been much debate about whether it is safe to eat cloned livestock and their offspring. US federal regulators began looking at cloned food safety four years ago as it became clear that the cloning technique that led to the 1996 birth of Dolly the sheep had commercial potential.
