How to identify the quality of straw micro-storage?
1. Look: After 21 to 30 days of sealing, the fermentation process can be completed. According to the external characteristics of the micro-storage, the quality of the micro-storage can be identified by the method of looking, smelling and feeling. The color of the high-quality micro-storage green corn (2400, -9.00, -0.37%) straw is olive green, and the rice and wheat straw are golden yellow. If it is brown or dark green, it is of poor quality.
2. Smell: The high-quality straw micro-storage has a mellow and fruity odor and has a weak sour taste. If there is strong acidity, it indicates that acetic acid is more, which is caused by excessive water and high temperature fermentation; if there is rancid smell and musty smell, it can not be fed.
3. Feel: The quality micro-storage feed is very loose in the hand, and the texture is soft and moist; if it gets sticky in the hand, or sticks to one piece, it means the quality is not good; some are loose, but dry and hard, Bad feed. The live dry bacteria used in micro-storage are anaerobic bacteria. As long as the operation instructions are used, the moisture of the storage materials is mastered, and the storage materials are compacted as much as possible, the excess air is discharged, and the fermentation is sealed to obtain a satisfactory high-quality micro-storage feed. .
What should I pay attention to when using straw micro- ?
1. Straw micro-storage feeds generally need to be stored in the pot for 21 to 30 days to feed, and in winter it takes longer.
2. When picking up the material, start from the corner and use it from top to bottom.
3. Each withdrawal should be done on the same day.
4. The mouth should be sealed immediately after each material withdrawal to avoid deterioration of the micro-storage caused by rainwater infiltration.
5. The tank should be cleaned every time the micro-storage is fed, and the micro-meal that is frozen in winter should be used after being opened.
6. Mild crop straws should not be made into micro-storage.
7. The micro-storage feed is added with salt, which should be deducted from the diet fed to the livestock.
9 How to feed straw with micro- ?
The crop straw micro-storage feed should be mainly fed grass-fed livestock, which can be used as the main roughage in the livestock diet. It can be matched with other forage materials when feeding, or fed with the concentrate. At the beginning, livestock have an adaptation process for micro-storage, which should be gradually increased gradually. The micro-stocking cattle and sheep diets are basically the same as the feeding silage, and no major adjustment is needed. Generally, the feeding amount of micro-reservables per head per day is: cows, bred cattle, beef cattle 15-20 kg, sheep 1-3 kg, horses, donkeys, clams 5-10 kg.
What is the key to the success of straw micro- production?
1. Compaction: Compaction is directly related to the important part of the success or failure of production. If the compaction is not tight, the residual air in the sputum is not conducive to the growth of the straw-fermented live dry bacteria, but creates conditions for the mold and spoilage bacteria, causing wastefulness such as mildew and deterioration.
2. Sealing: If the micro-storage straw is not compacted, the upper seal is not tight enough to cause the mold to deteriorate. The solution is to cover the plastic (9850, -65.00, -0.66%) film and press 20-30 cm thick on the top according to the method described above. To ensure that the air can not enter the raft. If the soil is inconvenient and the workload is large, the innovative micro-storage method of the Dachang County Animal Husbandry Bureau of Hebei Province can be used to cover the micro-storage straw with about 30 cm thick ammoniated straw, and then covered with plastic film. Buried, it can also solve the mildew caused by the lack of tightness in the upper part.
3. Micro-storage construction size: According to the number of cattle and sheep to be raised, under normal circumstances, 1 窖 micro-storage feed can be prepared for 2 to 3 months, such as feeding more than normal. Several micro-reservoirs were built for alternate use. The purpose of this is to avoid the problem of local deterioration caused by the lack of time after the opening. If a household only has 1 or 2 cows, it is recommended to use a plastic bag for micro-storage.
4. Micro-storage volume and weight calculation: Each cubic meter of micro-storage can accommodate 200-300 kilograms of dry straw. The more compact the pressure, the more loaded, which not only improves the utilization of micro-storage, but also ensures micro-storage. quality.

First, the live dry bacteria resurrection: cut the aluminum foil bag, pour into 200 ml of tap water, fully dissolved. Under conditions, you can add less than 2 grams of white sugar (5344, -18.00, -0.34%), dissolve in 200 ml of water, and then add live bacteria to dissolve, the revitalization rate can be increased by 10 times. Then, it is allowed to stand at room temperature for 1 to 2 hours.
Second, the bacterial liquid preparation: pour the resurrected bacterial liquid into a fully dissolved 1% salt solution and mix well. The calculation method of the amount of the salt solution is shown in the preparation table of the bacterial solution.
Third, micro-storage processing: cut the straw into 5 to 8 cm (for cattle) or 2 to 3 cm (for sheep).
Fourth, the construction of micro-storage: generally choose the place where the terrain is high, the drainage is easy, the soil is hard, and it is close to the animal house. The family raises cattle and sheep. Generally, it is suitable for height 2 meters wide and 1.2 meters long. It is best to build two 窖 at the same time for alternate use. If a household only has 1 or 2 cows, it is recommended to use a plastic bag for micro-storage.
5. Put a layer of 30 cm thick straw on the bottom of the raft and then pour the prepared broth on the straw according to the table. Use the foot to step on the ground. The more solid the step is, the more the straw is sprinkled. For the fifth of the corn flour, you can also mix the straw evenly outside the pot and spread it in the pot. Repeat several times until it is above the dome.
Sixth, spray the bacteria liquid should be uniform, the storage material should be fully compacted, exhausted air, and sealed, no air leakage. Before covering the plastic film, sprinkle 250 grams of salt per square meter and then cover with a plastic film.
7. Cover the plastic film with 20 cm thick rice straw or wheat straw, then cover 20 to 30 cm of soil. Do not use mud. Each cubic meter can contain more than 200 kilograms of dry rice straw and more than 300 kilograms of dry corn stover.
8. Micro-storage feeding: After the micro-storage is fermented for 30 days, it can be taken out for feeding. When starting to feed, from as little as possible, let the animals have an adaptation process and gradually increase the amount of feeding. When taking the storage material, how much is used, and then take the plastic film to seal the mouth after taking it.
