Pig straw straw feed production

First, biological feed production methods 1. Raw material selection and processing crush. Crop stalks should be selected from various above-average plant stalks that are free of mildew and rot, such as corn stalks, soybean stalks, weeds, leaves, distiller's grains, powder slag, rice bran, bean dregs, mushroom vinegar, vinegar residue, rice straw, straw, etc. Can be used as raw materials. 2. Dry the ingredients (preferably 3 or more) and pulverize them with a pulverizer. 3. The use of biological fermentation agent 500 grams, the ratio of starter and grass powder is 1%, that is, 50 kg of grass powder plus 0.5 kg of starter, and add clean water 75-90 kg. Before fermentation, the biological starter is placed in a container (cylinder, barrel, and pool), dissolved with a small amount of water at 15 to 20 degrees, and thoroughly mixed with a stick to dissolve it into a fermentation liquid. 4. After the fermented liquid is adjusted well, the grass flour and the fermented liquid are mixed according to the proportion, fully wetted, and the degree of wetness is suitable for drafting a powder and pinching a few drops of water. 5. Combine the grass powder in the mix (pool, cylinder, and barrel) into a tightly packed plastic film and tightly around it. Place it under a temperature of 10 degrees or more and 40 degrees or less. Fermentation 2— 5 days serve as a soft, cooked, sour, and scented biological feed. If the seal is good for long-term storage, it can be dried or dried. Second, feed formulation and feeding methods Fermented grass meal can not be a single use of biological feed, must be fed with the fine feed. For self-contained use, 30% of the grass feed can be used. 70% of the corn, bran, bean cakes and other mixed feed 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 this formula application. Grass meal 30%, corn 45%, bran 14.2%, bean cake 4%, soybean meal 12%, salt 0.25%, multi-dimensional 0.01%, 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 feeding amount is 2.5-3 kg (you can also flexibly control the feeding amount according to the size). Third, pay attention to matters 1. For the fermentation of grass powder, must be present with the current use, can not be left, but can not be placed too long. 2. During the fermentation process, the filling container cannot be leaked and cannot be opened halfway. 3. Quality appraisal, can use the method of seeing, sniffing, touch to identify. 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, remove it layer by layer and keep the rest of the material tightly sealed.
