NOVELTY - Livestock bedding material comprises crude proteins, crude fats, crude fiber, crude ash, nitrogen-free extract (NFE), acid detergent fiber (ADF), neutral detergent fiber (NDF), lactic acid, acetic acid, butyric acid, valerate and green bamboo powder. The livestock bedding material is prepared by crushing green bamboo branch and leaves to 5 mm diameter or less, and fermenting the powder using 200 million/1 g or more lactic acid bacteria, where the water content is 50-60 wt.% and pH is 4.7-6.2.    USE - The livestock bedding material is useful for preparing deodorized pig-feces fertilizer and livestock farming, preferably pig farming (claimed). The bedding material is also used as feed for improving breeding of livestock. The livestock farming chosen from cow, horse and hen. The deodorized pig-feces fertilizer is used in horticulture or gardening for cultivating ornamental plants.    ADVANTAGE - The bedding material is free of pollution, cost-effective and reduces offensive odor. The deodorized pig-feces fertilizer is convenient to use.    DETAILED DESCRIPTION - Livestock bedding material comprises 1-2 wt.% crude proteins, 0.2-1 wt.% crude fats, 18-25 wt.% crude fiber, 1-2 wt.% crude ash, 16-25 wt.% nitrogen-free extract (NFE), 23-32 wt.% acid detergent fiber (ADF), 33-45 wt.% neutral detergent fiber (NDF), 0.25-0.45 wt.% lactic acid, 0.20-0.35 wt.% acetic acid, 0.10-0.25 wt.% butyric acid, 0.01-0.06 wt.% valerate and green bamboo powder. The livestock bedding material is prepared by crushing green bamboo branch and leaves to 5 mm diameter or less, and fermenting the powder using 200 million/1 g or more lactic acid bacteria, where the water content is 50-60 wt.% and pH is 4.7-6.2. INDEPENDENT CLAIMS are included for the following:    (1) preparation of livestock bedding material, involves mixing green bamboo powder, silage and water in a ratio of 80:20-60:40, adjusting the water content to 50-60 wt.%, and mixing the mixture and fermenting the mixture, where the pH is maintained to 4.7-6.2;    (2) flooring livestock farming, involves intergrally spreading the livestock bedding material on the surface of water-retention concrete type floor; and    (3) pig farming system comprises discarded bamboo, waste material obtained after fermentation of koji and shochu liquid waste, where the materials are used as feed or bedding material for pig.
