Origen面临的另一个挑战是提高生产量。为了做到这点,他和Embrex合作研制了一个可将疫苗注入50000个鸡蛋中的仪器。Embrex正试图改造那个仪器,从而使胚胎和注射的细胞落在准确的位置而不杀死它。
在将来,Origen设想将不同品种小鸡的干细胞冷冻,如果定单要某一种小鸡,成百万的卵能在几个月甚至几个星期被生产出来,目前,维持市场可能需要的各种小鸡对养殖者来说太昂贵了,那要花数年的时间培育足够多的小鸡以生产出农民需要的上百万鸡蛋。
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 be 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 USs 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.
