Fermented bed sawdust pretreatment

Pretreatment of sawdust by the fermentation bed sawdust is a very good resource. The correct use of the sawdust can be multiplied. The use of sawdust to make a pig bio-fermentation bed is a very good use. The pig fermentation mattress material layer is mainly made of organic litter. The main components of the organic litter include sawdust, sawdust or crushed straw. Sawdust or sawdust accounts for approximately 90% of the total weight of the litter. Its soft texture absorbs much water. Therefore, the quality of sawdust directly affects the fermentation effect of the fermentation bed. Some customers do not pay attention to the quality of sawdust, and some of the toxic, mildewed sawdust is made into a fermentation bed, and naturally it will not receive good results. So what should you pay attention to when preparing a swine fermentation bed?
1. The source of sawdust should be clear. It must be ensured that the sawdust is non-toxic and that mildew has not occurred. Of course, the best is fresh dry sawdust.
2. Natural sawdust in the primeval forest is good because the fresh wood harvested from the original forest does not have any pollution, and the production of a fermentation bed is the best.
3, to avoid the residual chemical substances in sawdust, such as the secondary processing of wood preservatives, paint, asphalt and other chemical substances, so that the effect of fermentation bed not only is not good, but also affect the growth of pigs.
4. Some sawdust with impurities and chemical residues, sawdust with unpleasant pungent odors (such as oil pine sawdust) must be air-dried, washed, dried and then made into a fermentation bed so that most of the harmful substances have been degraded or separated. , Reduced residue, thereby reducing the hazard.
5, fresh sawdust has a relatively high moisture content, the best way is to go through the drying process, reduce its moisture content, and then increase the water absorption capacity of sawdust to achieve the desired fermentation effect.
