NOVELTY - Floor bedding comprises raw materials (in pts.wt.): agricultural crushed straw (50-80), waste residue obtained from fermentation industry (20-50), nutritional additive for microbial growth (0.4-0.8) and microbial inoculum for microbial fermentation (0.02-0.2).    USE - Floor bedding used in house for breeding animal e.g. cattle, sheep, pig, rabbit, chicken, goose and duck and for carrying, absorbing, dissolving and converting excrement of the fed animals (all claimed).    ADVANTAGE - The floor bedding is cost effective (because it requires fermentation of industrial and agricultural waste residue as main raw material), environment-friendly (because it keeps the ecological balance by converting excrement of the fed animals into excellent biological organic fertilizer), and suitable for big animal breeding farms.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for processing the floor bedding, which involves:    (A) crushing the agricultural straw and sieving it by 20 mesh sieve for use;    (B) performing filter pressing the waste residue obtained from fermentation industry and controlling the water content at 50-60% for use;    (C) dissolving the nutritional additive for microbial growth in water to obtain an aqueous solution of concentration 5-10%;    (D) dispersing microbial inoculum for microbial fermentation in 100 ml of water uniformly to obtain microbial inoculum dispersion liquid;    (E) mixing agricultural crushed straw, waste residue obtained from fermentation industry, nutritional additive for microbial growth and microbial inoculum for microbial fermentation to obtain a mixed material for main layer of bedding; and    (F) laying agricultural crushed straw uniformly to form 10-30 cm thick bottom layer of the bedding, where the main layer of 50-150 cm thickness is arranged on the bottom layer of the bedding and made by laying mixed material and microbial inoculum dispersion liquid at an interval, and the layer of microbial inoculum dispersion liquid is sprayed by defined proportion when one layer of mixed material which is 10 cm thick is laid, and the surface layer of the bedding is 10-30 cm thick and made by laying agricultural crushed straw.
