The raising and processing can be carried out throughout the year. As for the feed, besides a small amount of mulberry leaves, more evening primrose, Jiancan grass, white clover, cup plant (Silphium perfoliatum) and the like can be added to replace mulberry leaves, so as to supplement the shortage of mulberry leaves and reduce feeding costs.
