In summer, there are many rains and high temperatures. The relative humidity of the air is generally large. Combined with the action of microorganisms such as fungi and bacteria, feed and its raw materials are prone to oxidation, agglomeration and mold during storage, resulting in loss of nutrients and unnecessary waste.
1. Choose the storage location correctly and prepare for it.
The feed storage warehouse must choose a place with high terrain, dryness, coolness, good ventilation and convenient drainage. The surrounding walls and floors should be covered with cement to prevent leakage, anti-mouse and prevent the ground from returning to the tide. After the storage warehouse is cleaned, the doors and windows are closed for fumigation, and the packaging of the feed is disinfected with high-temperature steam. The material tank and the barrel are disinfected with 1:3000 poisonous solution. The feed should not be in direct contact with the ground wall during storage. It should be separated by a wooden bracket.
2. Control the water content of feed and raw materials
The water content of feed and raw materials is directly related to the storage effect of feed, high moisture, and the feed is prone to heat and oxidation, agglomeration and mildew. According to the test, the moisture content of the feed is more than 15%, and the mildew is most likely to occur. The rate of mildew of the feed is also increased with the increase of moisture content. Therefore, the moisture content of the feed should be strictly controlled during storage.
3. Control temperature and humidity, strengthen ventilation,
Low temperature, low humidity and good ventilation conditions are conducive to the storage of feed, preventing the oxidation and mildew of the feed. Generally speaking, the relative humidity of the feed storage room should be lower than 60%, and maintain good ventilation and ventilation, and reduce the temperature of the storage room as much as possible. Conditional thermometers and hygrometers can be installed to facilitate timely inspection. On the contrary, high temperature and high humidity are not conducive to the storage of feed. According to the test, when the temperature is below 10 °C, the mold grows slowly and the temperature is above 30 °C. When the humidity is suitable, the mold will rapidly multiply and the amount of mold in the feed will increase greatly. Causes mildew and deterioration of the feed.
4. Feed storage and safe storage period
When the feed storage time is long, it should be checked regularly, turn up and down in time, and ventilate and ventilate. It is found that the feed or raw materials are heated and released in a timely manner. The damp or hot feed should be used immediately or separately to prevent the other feed from agglomerating and mildew. When using, you should follow the principle of “new†and not mix new feeds. In addition, due to the special reason of high temperature and high humidity in summer, it is not advisable to buy too much material and ingredients, and the feed or raw materials should not be stored for too long. The bulk material should be used up to 3 days, and the bag material should not exceed 7 days, at the latest should be used within 10 to 12 days.
5. Timely rodent and insecticidal
Rats and worms not only consume feed, but also cause additional waste, and their activities also consume oxygen, produce carbon dioxide, water, and release heat, which causes the local temperature of the feed to rise and the humidity to increase, causing the feed to agglomerate and mold. Rats can also burrow holes in the walls and roofs, and smuggle the feed outwards. What is more serious is that rainwater will be poured into the storage room from the rat hole when it rains, causing more feed to be damp and mildew. Therefore, rodenticides and mousetraps should be used for rodent control. It is found that the feed insects should immediately pick out the insect feed, use the safe and efficient insecticide for insecticide treatment, and the other feeds to the insecticide to prevent the pest from happening again.
6. Application of high-efficiency feed anti- agent
Although the feed or raw materials are dried, they always contain a certain amount of mold. Once the conditions are suitable, they will grow and multiply quickly, causing the feed to die, so the mildew is the focus of summer feed storage.
