2010年9月29日 · The Enviropig is the first swine (a Yorkshire, to be exact) able to digest phytate on its own. The project started a decade ago when Cecil Forsberg, a biologist at the University of...

Enviropig™ is genetically engineered to produce the enzyme phytase in its salivary glands to enable more effective digestion of phytate, the from of phosphorus found in pig feed ingredients like corn and soybeans.

Almost two decades ago, researchers used genetic techniques to engineer a transgenic ‘Enviropig’ that could process phytates (Golovan et al., 2001). Now Zhang et al. have created transgenic pigs that express enzymes which allow them to digest both phytates and non-starch polysaccharides.

The best known example is the Enviropig: a pig that is genetically engineered to produce an enzyme that breaks down dietary phosphorus (phytase), thus limiting the amount of phosphorus released in its manure (Laible, 2009).

2010年4月2日 · Canada has approved for limited production a genetically engineered, environmentally friendly pig. The "Enviropig" has been genetically modified in such a manner that its urine and feces contain almost 65 percent less phosphorus than usual.

2003年2月1日 · The Enviropig is a transgenic pig that synthesizes phytase in the salivary glands and secretes active enzyme in the saliva. This capability enables pigs to utilize practically all the P in cereal grains and soybean meal and to excrete fecal material usually containing 60% less P than nontransgenic pigs fed the same conventional diet lacking ...

2013年3月7日 · Researchers say the new line is healthy and can pass the transgenic trait to new generations. A research team at the University of Guelph has developed a new line of transgenic "Enviropigs." The...
