Since last fall, a series of bird flus have been confirmed to be virus-free in all poultry farms by the 13th, and the epidemic has converged to some extent.
During this period, the number of chickens slaughtered was close to 10 million, the highest number ever, and experts say that the background was that the virus entered the area where the poultry farm was being scaled up.
Occurs at 52 poultry farms in 18 prefectures
Avian influenza has spread unusually since November last year, and has occurred in 52 poultry farms in 18 prefectures including Kagawa and Chiba prefectures, and the number of slaughtered animals is about 9.87 million, which is the highest ever in one season. I went up to the wings.
The poultry farms where the slaughter was carried out are conspicuous in large scale, with 20 places where more than 100,000 birds were bred and 3 places where more than 1 million birds were bred.
At poultry farms, corn, which is used as food for chickens, is also used as biofuel, and as prices continue to rise worldwide, management efficiency is required, and the average number of breeding is average for adults. The number of birds is increasing year by year, such as 67,000, which is 1.5 times that of 10 years ago.
In this season's bird flu, the virus entered a large-scale poultry farm and the number of cullings increased. Professor Yoshihiro Sakoda of Hokkaido University, who is familiar with bird flu, said, "Eggs are being supplied cheaply due to the large scale. It cannot be resolved immediately, but in the long run it is also necessary to reduce the number of poultry farms and the density of locations. "
