Chinese scientists said they have successfully cloned three 'super cow' calves that, once fully grown, are capable of producing 50% more milk than the average American cow.
Holstein Friesian cows
The so-called super cows were created using Holstein Friesian cows, a Dutch breed of cattle known for producing a higher than average amount of milk. Chinese scientists made headlines last year for cloning the world's first arctic wolf, but the super cow experiment has been hailed as another important breakthrough by the researchers, who also noted how much China depends on imports of cows.
Faced with rising demand for milk and cheese, China imports roughly 70% of its dairy cows from other countries. The nation has roughly 6.6 million Holstein Friesian cows within its borders, but only five in every 10,000 are actually capable of producing the high volume of milk, the Global Times reported.
Yaping Jin, a bovine veterinarian at Northwest A&F who led the experiment, told the Global Times that cloning will help revitalize China's agricultural sector. Jin said his team's experiment produced more than 100 cloned embryos that were implanted into the surrogates with a pregnancy rate of about 18% after 200 days.
