Some times I wonder why Japan has the wierdest inventions in the world?! This one is not so bad, and the least wierd?
A farmer thought tea is good for human, it must be good for pigs too, isn't it? He started a test in 1997, mixing tea in food for his pigs. When the pigs were matured for consumption, scientific examinations were done to these fleshes. The result reflected 3 times more vitamin C compare to pigs did not have tea. Amino Acid is also 3 times more, pig "smell" is significantly less, therefore taste better.
In 1999, Japan produced 40,000 of these "Tea Beauty Dolphin" pigs, catering to major cities like Tokyo in Japan.
