Method for storing feed ingredients

1. Controlling the moisture content of raw materials is an important measure for safe storage and quality assurance: the moisture content of bulk raw materials is generally below 13% (South) or 14% (North), and the moisture and dry weight loss of trace components should be below the standard requirements. Special feeds It should be determined as needed. The mold can grow under the condition of relative humidity of 75%. We put the feed under the condition of stable relative humidity, and gradually stabilize the moisture content to a level after a long time. At this time, the feed moisture is said to balance the moisture. In general, we balance the moisture that is achieved by a relative humidity of less than 70%, which is stored as safe moisture. The safe moisture of the feed is affected by the amount of hydrophobic or hydrophilic components and the ambient temperature. In production, different feed ingredients and different areas of safe moisture are different, such as 14.5% (Fountain, Zhejiang) 13.5% (other regions), soybean cake 13%, vegetable meal 12%, rice bran 13%, Bran 13%, winter wheat 12.5%, spring wheat 13.5%, rice 14%, sorghum 14%, corn 18% (Northeast, Inner Mongolia, Xinjiang), 14% (other regions). Different seasons, different regions, and different raw materials can stipulate different safe water values. For feeds that exceed safe water values, in principle, they should be refused storage. If they are to be stored, they must be dried and air-dried. dcV China Feed Industry Information Network - based on feed, serving animal husbandry

2. Measures to prevent and control microbial contamination: As feed ingredients are often contaminated by microorganisms during storage, the quality of raw materials is degraded, which seriously affects subsequent processing and production. Therefore, the detection and control of key points in the storage of feed ingredients should be given sufficient attention. In order to prevent microbial contamination of feed ingredients, raw materials must be stacked in accordance with the specified requirements, and measures such as moisture, mildew, and ventilation should be taken. At the same time, in the storage process, the quality control department conducts quality inspections on the raw materials in a step-by-step manner, and finds problems in a timely manner without leaving quality hazards. Adhere to the principle of first-in, first-out, and push the new rules. dcV China Feed Industry Information Network - based on feed, serving animal husbandry

3. Warehouses that meet the standard: store large- scale raw materials warehouses such as corn, soybean meal, cotton aphid, and secondary powder. They are required to be ventilated, rainproof, moisture-proof, insect-proof, rodent-proof and anti-corrosive. Store raw materials such as trace elements, vitamins, pharmaceutical additives, etc., in addition to ventilation, rain, moisture, insects, rodents and anti-corrosion, it also requires high temperature and light protection. After the daily work is completed, the warehouses should be cleaned, sorted and inspected. The problems should be dealt with in a timely manner, and the raw material storage places should be disinfected regularly. dcV China Feed Industry Information Network - based on feed, serving animal husbandry
