An Argentine laboratory announced that it had created the world's first transgenic cow, using human genes that will allow the animal to produce the equivalent of mothers' milk.
A cloned cow whose offspring's meat entered the British food chain may have more than 100 descendants in the country, records suggested Thursday, amid fears about their spread into the food system.
South Korean researchers said Wednesday they have successfully cloned a rare local species of cow in a government-funded project.
Scientists in China have cloned a dozen goats engineered with a gene that boosts wool growth, with a view to increasing output of cashmere fibre, state-run media reported Wednesday.
