Application of microbial fermented bean dregs in pig raising


Operation method: kilograms of wet bean dregs, kilograms of bran or straw powder (the dosage is based on adsorbing excess water in the bean dregs. If the bean dregs is already relatively dry, you do not need to add this part of the raw material), kilograms of corn flour, 3. Table salt, kg** beneficial microorganisms. After mixing, compaction and sealing fermentation, it can be fed when a slight wine aroma or sour aroma wafts out within 1 day (depending on the temperature). When starting to use it, it is recommended to discard the thin white layer on top and seal it tightly again immediately after each withdrawal to prevent spoilage.


When fermenting ingredients, the more corn flour is added, the stronger the wine aroma will be. If less corn flour is added, the sour aroma will be more prominent and the wine aroma will not be strong. It should be pointed out that the time when a relatively obvious wine aroma is produced only during the vigorous fermentation period, and only for a few hours. After the vigorous fermentation period, the wine aroma will not be smelled. If the fermentation peak occurs at night, you may have missed the opportunity to smell the aroma of the wine. Generally, the fermentation peak occurs about two days after fermentation.

If the fermented materials are to be stored for a long time, they must be tightly sealed and compacted, and the air in the packaging bag should be exhausted as much as possible. , the degradation will continue, and after a longer time, the digestion and absorption rate will be better and the nutrition will be better. The same principle applies to other solid fermentation residues. Of course, the prerequisite is to ensure strict sealing and no air leakage into the material. The longer the time, the better the quality and the better nutrition (but in actual production, many users cannot Make sure the sealing is tight, so it is recommended to use it up as soon as possible).

No matter what the formula is, it is best to try feeding a small amount first, and there must be a process of acclimation. For example, feed it with a certain amount first, and then increase it after it adapts to it. In this way, slowly increase the amount. Until large pigs can reach the highest dosage, and sows can even use the highest dosage.
