The invention discloses a method for producing a 
forage immune 
enhancer by adopting a soybean curb residue and an orange peel. The method comprises the following steps: respectively crushing the soybean curb residue, dried pine needles, dry 
dunaliella cells and dry orange peel into coarse 
powder of 60-80 meshes; burdening the raw materials in parts by weight: 45-50 parts of soybean curb residue, 30-35 parts of dried pine needles, 2-5 parts of dry 
dunaliella cells, 15-18 parts of dry orange peel and 2.0-2.5 parts of an assistant, wherein the assistant is prepared from 49 parts of NaHCO3 and 1 part of MgSO4; the 
moisture content of the pine needles, the 
dunaliella cells and the orange peel is 3-5%, the 
moisture content of bean dregs is 18-20%; mixing the mixture of four coarse 
powder with the assistant according to the ratio, wherein the assistant accounts for 2.0-2.5% of 
dry weight of the total material; evenly mixing and then 
grinding for 30 minutes; filtering by a 400-mesh 
sieve; 
processing by using 
enzyme-aid 
micronization treatment, so as to obtain the 
forage immune 
enhancer product, wherein the 
treatment time is 15-30 minutes according to the quality and the 
humidity of the raw materials. By adopting the 
forage immune 
enhancer produced by the method disclosed by the invention, the production cost of the raw materials is significantly reduced, a lot of waste bean dregs produced in bean product production are recycled, low-carbon production is achieved, and the added value of products is increased.
