After the ecological fermentation bed is constructed, the next task is to start and run. The use of fermentation bed leavening agent can be started in 1-3 days in the summer. It is only a dozen degrees or even tens of degrees in the cold winter, as long as the insulation measures Well, it will start within three or five days. It can be seen that the start of the fermentation bed is very simple, and it is basically not affected by the seasonal climate. Its focus is on the daily management and post-maintenance of the fermentation bed during its operation.
To ensure the normal operation of the fermentation bed, it is necessary to first understand the basic conditions for the normal operation of the fermentation bed, namely the species, the thickness of the litter, the moisture in the litter, the temperature, the nutrients needed for the bacteria (provided by the excreta), and Ventilation, ventilation, etc. The importance of bacteria is self-evident, because the decomposition of wild boar's excreta depends on the life activities of microbial strains. The types of microorganisms, the strength of microbial activity, the number of strains and their activity are extremely important. Moisture is also very important. The optimum moisture content of the fermentation bed strain is 60%. If the moisture is high or low, it will directly affect the decomposition of the excreta. The thickness of the bedding is an important standard for the production of a fermentation bed. The fermentation bed requires 50 cm. (Other manufacturer's fermentation beds generally require a thickness of 80-100 cm.) The thickness of the bedding (50 cm for wild boar, 40 cm for rabbits, pheasants, etc.) This thickness is the thickness of microorganisms that can normally decompose the feces and is too low At this thickness, the "core fermentation layer" is forced to become a "protective layer" or "buffer layer," and the "core fermentation layer" that is really required for functional strain fermentation disappears, and there is no room for survival of functional bacteria, which will lead to The ability of microorganisms to decompose and decompose feces is reduced or terminated, so the basic thickness of the litter should be guaranteed. The general temperature range (from minus tens of degrees outside the ambient temperature to 45 degrees above zero) has little effect on the viability of the already started fermentation bed, but it has a great influence on the growth activity of the wild boar in the fermentation bed, and the temperature is too high or too high. Low will affect the feeding and growth of wild boars. Due to the restrictive factors mentioned above, it is possible to ensure the safe, continuous and stable operation of the fermentation bed by adjusting the ventilative air permeability of the housing.
Second, non-standard fermentation bed bad scourge
Breathability of the fermentation bed house directly affects the vitality of the bacteria species and the moisture and temperature of the house. Poor ventilated ventilation generally leads to the following adverse consequences.
1, fecal decomposition is slow or does not break down. Poor ventilation results in little or no heat, and litter temperature is low. This is mainly due to the fact that most of the bacteria in the fermentation bed are oxygen-consuming strains. If there is a lack of oxygen in the housing, microbial activity will be greatly inhibited. Decomposition of feces or failure to disintegrate in time will lead to excessive accumulation of feces, heavy ammonia, and high concentration of carbon dioxide in the pens. The anaerobic bacteria are active and produce harmful gases such as humic ammonia, ammonia, hydrogen sulfide, etc. Air irritates the mucous membranes of the respiratory tract, causing mucous membrane congestion, resulting in conjunctivitis and respiratory diseases; hydrogen sulfide is a strong neurotoxin, has a strong irritant, can also cause conjunctivitis and respiratory diseases, so that the wild boar can not grow normally or grow slowly. With wild boars originally living in the outside world, the requirements for the environment and air quality are relatively high, so it is even more careless.
2, increase the humidity or drops of water droplets. For the normal and stable operation of the fermentation bed, due to a large amount of water vapor, carbon dioxide and other gases generated during the operation process, timely or regular ventilation is required to discharge these gases out of the housing. If it is not discharged in time, it will be easy to fog in the winter housing. , At the same time, water vapor rises in case of poor ventilation and cold plastic film ceilings, or foamed plastic ceilings, color steel plates, etc., will condense into water droplets and even form a drop back into the fermentation bed, resulting in partial or entire fermentation bed surface moisture, poor ventilation It eventually led to the death or bad bed of the fermentation bed bacteria, resulting in the production of a large number of fly maggots. The wild pigs slept on cooler beds and suffered from colds. Poultry larvae in poorly ventilated corners are also often found in poorly ventilated housing.
3, house hot or cold cold. The poor ventilation of the winter fermentation bed can cause the temperature of the house to go up. The winter temperature is too low and the wild boar will catch cold and grow slowly. In the summer, the bad ventilation will cause the air in the fermentation bed to be stuffy, excess heat, carbon dioxide and ammonia. Can not escape or spread too slowly, affect the healthy growth of wild boar.
Third, take effective measures to improve ventilation
Ventilation is affected by many aspects, summer and winter are not the same, north and south are not the same, dry and wet areas are even more different, should be timely, according to local conditions, take effective measures to improve the ventilation ventilation of the pens, and promote the health of wild boar Fast growth.
1. The structure must be reasonable. First of all, we must start from the structure of the shed. The wild sty is best to face south and south and north and south, with a certain span and height, and places with high dryness, etc. (Specific information can be requested from the company).
2, to ensure that the "four windows" complete. For large and medium-sized farmers or farms with conditions, overall windows, skylights, windows, and induced draft fan windows should be considered (small-scale or retail households have lower requirements for breeding, with skylights, windows, and conventional windows). With both natural ventilation and mechanical ventilation, the ventilation of the windows can be opened when the air circulation is good (the summer window is always open, the winter is open at high temperatures at 12-14 noon, and it is closed at night), and the sunroof is opened to remove ammonia. Gases with low molecular weight such as gas, the ground window is a gas with a relatively large molecular weight such as carbon dioxide, and windows and windows have better effects on the discharge of water vapor. In hot weather, air flow is negative, or indoor and outdoor temperatures exceed 10 degrees Celsius. The situation should consider the use of forced draught fan ventilation to enhance air mobility, to avoid excessive heat and heat exchange caused by window opening.
3, timely upset shake. The purpose of the upturning of the fermentation mattress material is to increase the air permeability of the litter and prevent the litter from being excessively compacted to cause local or short-term anaerobic fermentation. During the turbulent process, a large amount of water vapor can be lost and can be effectively reduced. Moisture and heat in the fermentation bed (in the summer it is particularly effective to adjust the moisture quickly). When you turn over, you should open the window or draw the fan to make the water quickly lost.
4, cement brick partition to change the iron fence. Increasing the ventilation performance in the housing also reduces the retarding effect of various unreasonable facilities on the flow of air. If the existing columns are separated by common brick walls, they should be separated by iron fences, which can greatly reduce the air flow resistance. It also reduces dead air flow (air, ammonia, carbon dioxide, and other harmful microorganisms are extremely high).
The fermentation bed housing is well ventilated and breathable. Together with other supporting measures, the safe, continuous and stable operation of the fermentation bed is also basically guaranteed. The production of wild boar with delicious meat and robust system is also guaranteed!
