To keep the animals alive while preventing damage to resident's property, the Kibo-no-Bokujo -- Fukushima Project is working on a plan to enclose the animals on Yoshizawa's farm, where researchers will use them to observe the effects of radiation on large mammals. They are planning to get help from universities and other research institutes.
Earlier, in May of this year, university researchers asked the central government to let livestock exposed to radiation in Fukushima Prefecture live for use in research. Senior Vice Minister of Agriculture, Forestry and Fisheries Nobutaka Tsutsui expressed support for the idea, but almost no concrete measures have been mapped out.
According to the Kibo-no-Bokujo -- Fukushima Project, there were approximately 3,500 cows, 30,000 pigs and 680,000 chickens remaining in the 20-kilometer radius no-entry zone, which got that designation on April 22. On May 12, the government decided to slaughter all livestock in the zone, and it has so far killed about 300 cows. Most of the pigs and chickens are believed to have died from lack of water and food without people to look after them. Not counting any remaining chicken, there are estimated to be somewhat less than 2,000 animals left, mostly cows.
