Do you know that Japanese pig farming that continues to restrict pigs have very bad breeding grades?

The results of Japanese pig raising are not good.

The breeding ability per sow is largely separated from overseas.

The industry says that it is because the species are different, but the species used in the pig farming in Japan originally originated from the UK or Denmark. Although some species have been modified in Japan, species will not be a problem.

In addition, few farmers breed the kind of pig (Duroc) which originally has few births.

The climate certainly differs in each country and region, but it is the same handicap everywhere.

The big difference is whether they do restrained breeding or not considering animal welfare.

	Japan	USA	Netherlands	Denmark
Annual number of childbirth (time) (a)	2.3	2.4	2.4	2.3
Cultivating number per birth (head) (b)	9.9	10.7	12.3	13.6
Annual weaning number (head)(ａ)*(ｂ)	22.8	25.6	29.5	31.4

From ambiguous and concrete Japanese flow animal welfare, you should switch to the original scientific and useful animal welfare now.
