the method is characterized in that water is added and uniformly mixed, the mixture is immediately filled into containers such as a cylinder, a barrel, a pool and a plastic bag, the materials are completely sealed but cannot be compacted, when the container with poor sealing performance is used for fermentation, a sleeve is added outside, the sealed plastic bag can be tightened, the sealed plastic bag can be noticed that the container cannot be disassembled and overturned in the sealing process, the container is sealed and fermented for 2-3 days at the natural air temperature, the fermentation is finished when wine aroma or soil flavor exists, the feeding can be carried out, the fermented finished product is noticed to be immediately sealed after the material is taken and fed every time, the condition of a pig farm is investigated and counted, and the rule is found: the piglets added with the fat feed have good development and high disease resistance, and especially the piglets with lower birth weight have more obvious effect, and the basic reason for improving the feed efficiency by the fat is as follows: the inherent characteristics of high energy, easy absorption and easy utilization of the grease, the grease can provide a large amount of fatty acid, particularly necessary amino acid for monogastric animals, the energy content of the grease is high, the grease is easy to be utilized by animals, the energy utilization of other components of daily ration can be improved by the grease, the measured value of the metabolic energy of the grease is reported to be highest when the addition amount of the grease is 5 percent, the metabolic energy value is reduced when 10 percent and 15 percent of the grease are added, the second step is that corn, peeled soybean meal and core materials of big pigs are stirred and mixed, then the fourth-stage soybean oil and cellulose are added, a proper amount of PH regulator is added to ensure that the PH value is between 5 and 7, the PH regulator is regulated by calcium formate, the fourth-stage soybean oil and the cellulose are added and heated to 50 ℃ for mixing, the mildew-proof effect of the feed mildew preventive is not changed at all, even if the same variety and same dose of mildew preventive are used, there are also significant differences in the use of different types of feed, so that the following problems should be noted when using mould inhibitors: the pH value of the feed and the optimal pH value range of the bacteriostatic action of different mildewproof agents are different, for example, the optimal pH value of benzoic acid is 2.5-4.0, and the feed has no effect on a plurality of mildews when the optimal pH value of benzoic acid is more than 5.5; sorbic acid can be used at more than 5-6; the optimum pH value of the propionic acid is below 4.0; the content of dimethyl fumarate is within 3-8, so that the pH value of the feed and the water content of the feed should be noticed by selecting the mildew preventive, the water content is one of the most important factors for determining whether the mildew in the feed can grow, and the mildew is easy to grow when the water content in the feed exceeds 13-14%; when the water content in the feed exceeds 15%, the growth speed of the mold is accelerated, and the generation of toxins is correspondingly increased, so that the using effect of the feed mildew preventive is improved, the water content of the feed is preferably controlled to be below 14%, the temperature and the humidity are proper, the mold harmful to grains can grow at the temperature of 7 ℃ and the humidity of 75%, and the growth and the development are fastest when the temperature is 20-30 ℃ and the humidity is above 80%;
