The invention discloses a fermentation bed of cane byproducts for cattle. Padding of the fermentation bed comprises alkalized bagasse, sugarcane leaves, bacteria fermentation liquid which is obtained by adding molasses into microorganism inoculants and a mixture which includes unite bran, urea, wheat bran and corn flour. According to the fermentation bed of the cane byproducts for the cattle, the bagasse is alkalized for treatment, the sugarcane leaves are rubbed so as to make the cattle walk and lie on the sugarcane leaves comfortably, so that the growth of the cattle is facilitated; through the development of the fermentation bed of the cane byproducts for the cattle, not only can the problem that an breeding environment of the cattle is polluted seriously in a traditional breeding method be solved, but also a large number of microorganisms which are bred and grow provide the cattle with inorganic nutrition and bacterial protein which can be eaten by the cattle in turn and at the same time; besides, the cane by-products are made full use of, and therefore the fermentation bed is simple in production process, low in cost and worthy of promotion and application in wide cane areas.
