Denmark attaches great importance to raising pigs and environmental protection. For example, they use some pig manure as fertilizer and recycle it. They not only raise pigs, but also grow some crops and fish, so they have their own workflow in this ecosystem. For example, when pigs pull feces, they can be used to water their own crops. When crops grow up, they can be used to feed pigs, and some things from crops can also be used to feed fish. So this powerful industrial chain makes their pig industry very developed.
Danish pig-raising technology ranks first in the world. Why do you say that? They are not only very good at raising feed or pig house conditions, but also very good at raising pigs. They always believe that you can raise pigs with knowledge. Without knowledge, it may take three years and five years of training to get the qualification certificate for raising pigs. Therefore, raising pigs is also a technology, not just raising them casually.
