Clone Farm
Factory farming could soon enter a new era of mass production. Companies in the US are developing the technology needed to "clone" chickens on a massive scale, once a chicken with desirable traits has been bred or genetically engineered, tens of thousands of eggs, which will hatch into identical copies, could roll off the production lines every hour. Billions of clones could he produced each year to supply chicken farms with birds that all grow at the same rate, have the same amount of meat and taste the same.
This, at least, is the vision of the US’s National Institute of Science and Technology, which has given Origen Therapeutics of Burlingame, California, and Embrex of North Carolina $ 4. 7 million to help fund research. The prospect has alarmed animal welfare groups, who fear it could increase the suffering of farm birds.

A. Origen and Embrex will jointly invent machines to increase production.
B. Origen wants to purchase an efficient donor cells injecting machine.
C. Origen has joined hands with Embrex in producing cell-injecting machines.
