1, with a good material: ready soybean dregs (add 60% or so), rice bran, rice straw (crushed and add 5-15% or so), corn flour, feed fermentation agent (0.2% of the weight of fermented materials) and other materials.
2, adjust the moisture: moisture content is generally controlled between 60% -65%.
3, sealed fermentation: the material will be loaded into the fermentation tank, fermentation bucket and other sealed containers, and then in the ventilation of the fermentation can be, there is a wine aroma overflow, which indicates that the fermentation is successful.
4. Precautions: the material should not be moldy and half deteriorated; stored in a cool and dry place.
First, with good materials
1, ready to soybean dregs, rice bran, straw, cornstarch, feedstuff fermentation agent and other materials. Among them, according to the weight of the material to be fermented 0.2% ready to feed fermentation agent.
2, first of all, with fresh rice bran will fermentation agent according to the ratio of 1:5-10 dilution (each kilogram of fermentation agent plus 5-10 kilograms of rice bran); and then crushed rice straw, add 5-15% or so, and then add 60% of soybean dregs, the rest of the rice bran or cornstarch instead of rice bran, cornstarch and soybean dregs can be based on the proportion of soybean dregs, moisture and other actual conditions of the proper adjustments; and finally add the prepared The last addition of the prepared fermentation agent can be.
Second, adjust the water
The material will be well mixed, and then add water to mix, the water content is generally controlled between 60% -65%. Add water when the first less, close to the requirements (65%) to slowly add, to prevent excess water exceeds the standard, with a hand grasp can leave a print but not dripping water can be. In case of excess water exceeds the standard, you can add dry material to adjust the humidity.
Three, sealed fermentation
1, sealed fermentation containers include: fermentation tank (for dedicated users, large households, feed mills), fermentation tank, fermentation bucket (for small households, retail households), fermentation plastic bags (for small households, retail households) and so on. Note that the sealing must be good, do not easily move the container to avoid leakage.
2, will be stirred evenly into the sealed container of dregs, placed in a ventilated place to ferment can be. When the color of the dregs becomes olive green or yellowish brown, with the aroma of wine overflowing, it means that the fermentation is successful. In the process of fermentation, pay attention not to casually open the bag to see, open the bag should be immediately tied.
Fourth, note
1, the fermentation of raw materials can not be moldy and deteriorated, or have a strange smell. After the fermentation is completed, if the material is moldy or has a bad smell, it can not be used to feed animals.
2. It should be sealed when stacking and loading, but not pressed.
3, it should be stored in a cool and dry place, if you take the material from the container or bag to feed, you should immediately seal the container, the exposure time should not be too long, so as not to avoid corruption and spoilage.
4, to feed animals fermented soybean dregs feed, at first a small amount of feeding, and then slowly increase, the beginning of the available 10%, slowly increasing to 30%, 50%.
