The pigs in the fermentation bed are bred with pigweed in the pig farmer's shed, using the golden bacon dry-leaf-fermentation bed strain plus sawdust bedding to decompose the urine of the pig's faeces, so as to achieve deodorization and environmental protection. There is no need to clean up the excrement. What mat material is best for litter and how long can it be used?
The role of fermentation mattress material
Fermentation mattress material is mainly an environmental medium for the decomposition of fecal urine by microbial fermentation strains, and litter is also decomposed by bacteria. Therefore, the padding of pigs in the fermentation bed is preferably a pad with a relatively high carbon and nitrogen content. Generally, it can be used. Sawdust, rice husks, straw, cotton stalks, peanut hulls, etc. used alone or in combination, the effect of litter is generally sawdust> Cotton stem> Peanut shell> Rice husk> Straw> Rapeseed cake, sawdust is best, because the ratio of carbon to nitrogen is the highest, most It is resistant to fermentation and has the longest service life. Sawdust is loose and porous, and fineness is more suitable. Breathability and water retention are the best. The use of rice husk straw and so on for several months.
Sawdust selection criteria and treatment methods
Sawdust can not use sawdust of poisonous species, can not use sawdust containing latex and paint, sawdust fineness can not be too fine, can not be less than 1-0.5 mm, too small sawdust will cause the fermentation bed from dust, will have an impact on the breathing of pigs, The respiratory tract is irritated. Sawdust 2-3 mm in size should be used as far as possible. It can not afford dust, good air permeability, and long service life. The sawdust bedding used for the fermentation bed can be exposed to sunlight for 2 days in advance. The first is to kill the eggs and germs in the sawdust to prevent the growth of the eggs and other bacteria after the late fermentation bed to affect the growth of pigs. The moisture in the sawdust bedding can be removed.
Sawmill litter service life
The use of sawdust as a fermentation bed can generally be used for 2-3 years. It is not that the bedding is added once. After 2-3 years, it is gone and it is done again. Because the golden bacon dry-sweeping bed pigs need to ensure that the thickness of the litter is 50cm, as the fermentation bed's use time increases, the litter will continue to decrease in the decomposition of the fermentation, so after a half year or after a year, it needs to be replenished in small quantities. The dunnage is 50 centimeters. It is recommended to replace the dunnage after 2-3 years. If you do not change, you can also add supplements. The purpose of the replacement is that due to the use of litter for 2-3 years, most of the litter loses the original physical properties of sawdust, there is no new sawdust bedding size and permeability, in addition, the use of long fermentation bed sawdust mat As expected, there will be a lot of bacteria and nematodes, which will easily cause pig diseases.
The disadvantages of sawdust as a litter
Although the use of sawdust padding for pigs in fermentation beds is good, but sawdust is generally the highest price, and the cost of the production of fermentation beds is increased, the cost of sawdust bedding per square meter of fermentation beds is generally around 40 yuan (depending on the local sawdust price. There is a difference. If the local sawdust bedding is not easy to find, it can be used with rice husk or straw. If straw is used, it can be crushed to 3-5 cm or so. Spread to the lowermost layer of the house, 20 cm, and use a sawdust for 30 cm, if it is rice husk. Alternatively, the peanut shells, etc., can be laid evenly after being mixed with sawdust, so that the permeability of the fermentation bed can be increased and the cost of the fermentation bed can also be reduced. Peanut shells need to be crushed to about 0.5-1 cm.
Fermentation bed is a new type of environmental protection breeding mode. It can deodorize and protect the environment without cleaning up the excrement. However, the fermentation bed is not a panacea and has a certain service life. It also requires scientific management and normal disinfection.
