Crop stalks should be medium or above without mildew, rot and various plant stalks, such as corn stalks, soybean stalks, weeds, leaves; distiller's grains, powdered slag, rice bran, bean dregs, bacteria vinegar, vinegar residue, straw, straw and so on. The raw materials (preferably more than three types) are dried in the sun, powdered with a pulverizer, and then used for 500 g of biological starter. The ratio of starter to grass flour is 1%, ie, 100 pounds of grass powder plus 1 pound of starter , And add 150-180 pounds of clean water. Before fermentation, the biological starter was placed in a container, dissolved in a small amount of water at 15-20 degrees, and thoroughly mixed with a stick to dissolve it into a fermentation broth. When the broth is adjusted, the grass flour and the fermentation broth are mixed according to the proportion, fully wetted, and the degree of wetness is determined by grasping and drafting the powder and pinching to squeeze out a few drops of water. It is then advisable to mix the mixed grass powder (cylinder, The pool and barrel are tightly packed and covered with a plastic film. The surrounding area is tightly closed and placed under a temperature of 10OC or more and 40OC or less. After 2-5 days of fermentation, it is a soft, ripe, sour, and savory biological feed. If the seal is good, it can be stored for a long time without deterioration, or it can be dried by drying. The fermented grass pollen cannot be used alone and must be fed together with the concentrate. For self-contained use, 30% of the feed for grass meal, 70% of corn, bran, bean cake, etc. can be used to feed the pigs. It is also possible to feed 30% of grass feed and 70% of commercially available feed. In order to facilitate the farmers to master the formula and application, reference can be made to the application of this formula, namely: 30% grass flour biological material, 45% jade material, 14.2% bran, 4% soybean cake, 12% soybean meal, 0.25% salt, and 0.01% multidimensional. Trace elements 0.05%. Nutritional level of feed formula: digestive energy 2.648 megacalories/kg, crude protein 14.3%, crude fiber 9.04%, phosphorus 0.39%, lysine 0.66%, methionine 0.77%. The formula can achieve the nutritional standards for growing pigs. The daily amount of 2.5-3 kg. (You can also flexibly control the amount of feed according to the size.) Points to note: 1. Bacterial liquids used to ferment grass powder should be ready for use and must not be left over, and they must not be placed for too long. 2. During the fermentation process, the filling container cannot leak, and it cannot be opened halfway. 3, quality appraisal, can be used to see, smell, touch the method of identification. Look: The fermented grass flour is golden yellow or sauce color, no mold growth or blackening; Sniff: The fermented grass flour has sour flavor, no odor such as mildew, etc.; touch: fermented grass powder, with Hand feels softer than before fermentation. 4. When using the fermented fodder, it should be taken one by one, and the rest should continue to be tightly sealed.
