Maintenance of the fermentation bed The maintenance of the fermentation bed after the completion of the laying of the fermentation bed is also very important. The service life of the fermentation bed and the use effect are affected by the maintenance management. The maintenance management can increase the service life of the fermentation bed instead of the maintenance management. The insufficiency of the fermentation bed will greatly reduce the service life of the fermentation bed and will greatly reduce the use of the fermentation bed. So how can we do a good job in the maintenance and management of the fermentation bed?
First of all, ventilation is necessary because most of the functional microorganisms in the fermentation bed are aerobic microorganisms and require the participation of air, so it is necessary to ensure good air flow in the housing. The structure of the pen quarters is to be “complete with four windowsâ€. The four windows are skylights, windows, exhaust windows, and windows. The various windows play a different role in the normal operation of the housing. For example, skylights mainly emit gases with lighter molecular weights and higher temperatures, such as ammonia gas, and the ground windows mainly emit gases with larger molecular weights such as carbon dioxide and hydrogen sulfide. The main purpose of windows is to complete gas exchange in the middle of the housing, such as water. Steam, exhaust windows are used mainly in hot summer or cold winter seasons: sweltering summer air does not flow, can be forced ventilation, will take away excess heat, keep the cool feeling of the house; cold winter, the temperature in the house Above 15 degrees, and outdoor temperature below zero, the outdoor temperature difference is more than ten or even twenty degrees. If you open the window directly or open the door for ventilation, it will cause a strong heat exchange, and you can use a fan for ventilation. At the same time, the partition between the pen and the pen is best to use the railing instead of the cement wall to ensure the air mobility between the pens.
Secondly, avoiding the soaking of the padding in the soaking fermentation bed will result in a decrease in the permeability of the fermentation bed, which will prevent the fermentation from proceeding smoothly. Failure of the fermentation will lead to more and more decomposing of the sewage and result in a vicious cycle. In order to avoid the fermentation bed being immersed in water, it is necessary to do a rainproof measure for the shed so as to avoid soaking the shed in case of rain, and at the same time installing a diversion trough below the drinking fountain to facilitate the discussion of excess water and water pipes. Water that flows out of the enclosure when it bursts. Avoid excess moisture soaking the litter on the fermentation bed.
In addition, the overturning, tumbling, and upset movements are crucial to the operation of the fermentation bed. Due to the different growth habits of the pigs, there is a need to turn over the arches, and some do not like to turn over the arches. Pigs who do not like arching tend to grow longer with pigs on fermented mattress materials, resulting in more and more dense litter, affecting the loss of excess water in the litter and the air permeability of the litter. In severe cases, it also leads to fermentation. Termination. This requires manual turning to turbulence, so that the dense structure of the mat becomes more loose. The frequency of overturning depends on the specific conditions of the fermentation bed. It generally increases with the increase of the density of the cultured bed and the weight of the pig.
The above points are the points that need special attention in the operation of the fermentation bed. After doing the above points, the operation of the fermentation bed will certainly be no problem.
