These transgenic goats, created by Randy Lewis at the University of Wyoming , produce about a half ounce of silk from every quart of milk--the equivalent of a hundred spiders.

怀俄明大学的兰迪·刘易斯创造出的这些转基因山羊产的奶，1夸脱能制成大约0.5盎司丝，这相当于100只蜘蛛产的丝。

Approaches being tried include deriving fiber from the milk of transgenic goats with an extra spider-silk gene and adapting silk produced by other insects, such as silkworms.

正在尝试中的方法包括从具有额外蜘蛛丝基因的转基因山羊的山羊奶中获得纤维和改造例如蚕这样其它昆虫的丝。

Transgenic goats carrying a human gene, for example, are used to produce a human protein now licensed for use during surgery in patients whose blood otherwise fails to clot correctly.

例如，现已批准携带人类基因的转基因山羊生产一种人类的蛋白质，用于治疗手术中凝血异常的患者。

Nexia became known as the spider-silk company, after it created transgenic goats capable of producing spider silk (which is, in fact, a form of protein) in their milk.
