• China achieves a cloning breakthrough with the creation of three 'super cows.'

• Animal cloning is mainly used to improve the quality and productivity of livestock, as well as for conducting research in the field of biotechnology.

• Earlier, China cloned various species, including cattle, sheep, pigs, horses and even pets.

Chinese scientists have successfully cloned three cows that can produce an unusually high amount of milk, state media reported. According to researchers, these cloned cows are capable of producing 50% more milk than the average American cow.

Scientists sampled tissues from cows across China and used what's called the somatic cell nuclear transfer method, which involves taking the nucleus from a body cell of the animal to be cloned and transferring it into a donated egg cell. Then embryos were placed inside surrogate cows.
