At present, there is no special technology for raising snakes, because snakes are sacred in China, and people in China do not have the habit of eating snakes, so all agricultural colleges and universities do not have the specialty of raising snakes. The largest number of snakes should be zoos or some acrobatic troupes, but there is no special training base, and they are all groping by themselves. Raising snakes is a special kind of breeding, and there is no ready-made technology and special varieties. Be careful even if someone sells snakes in the market. They may not be able to feed them well and reproduce.
