Pig-raising in the fermentation bed has been increasingly recognized by the farmers, especially after the introduction of the new environmental protection law, the pollution penalty and demolition orders imposed by the environmental protection department on the breeding enterprises have allowed more people to understand and use the fermentation bed. The growing acceptance of the fermentation bed, especially the ginba dry fermentation bed, has also been understood by many, but it is hesitant to use the fermentation bed, especially as the fermentation bed is hot in summer. The following describes the main points of the management of the fermentation bed in the summer and the fermentation bed.
First, the principle of fermentation bed culture in the quarters evenly spread gold baby starter mixed with bedding sawdust, the total thickness of about 50 cm, put the animals into the bed to pull urine, usually from the first 2 to 3 days to start heating, After 3 to 7 days of functional colonization, functional microorganisms multiply in geometric progression (up to 272 in 24 hours of theoretical breeding). Animal manure is used as a nutrient source to warm up the litter mixture gradually. Layer temperature up to 35-50 °C or higher, surface temperature in winter and summer, long-term stability in the twenty-odd degrees, the basic formation of a constant temperature bed. After the completion of the lower fermentation, sawdust and other matting materials will gradually darken and darken due to the coloration of the fermentation carbonization. The fermentation product can be used as fertilizer or roughage, and can be transported in batches. Eco-fermentation bed can decompose feces through fermentation and can achieve odor-free cultivation. It does not need to clean up feces, no flushing, no groundwater pollution, no odor gas pollution, and achieves “zero emission†of breeding. It truly achieves aquaculture emission reduction standards. Fundamentally Solve the farm pollution problem.
Second, the fermentation bed is not hot Jinbao dry-type fermentation mattress material is composed of sawdust, the thickness is 50 cm, the fermentation manure layer is generally 30-15 cm, the fermentation temperature is generally 30-40 degrees, the individual will reach At 50 degrees, sawdust has poor thermal conductivity, and the surface temperature of the dry spreader is generally only about 20 degrees, which is basically at room temperature or slightly higher than room temperature, so the fermentation bed is not as hot as we think. The wet fermentation bed will be warmer than the dry fermentation bed. In addition, the pigs themselves are very hot in summer, so we must manage the main fermentation beds in summer.
Third, the summer management of the fermentation bed The climate characteristics of summer are: high temperature, high humidity, especially hot and humid, although the hot and humid climate throughout the year is not long, but if you do not take effective measures against these climate characteristics, may give the fermentation bed Normal operation has had some adverse effects. Beijing Huaxia Kangyuan's Goldbaby Fermentation Acoction Fermentation Aid in the process of farmers, for the fermentation bed pigs "three afraid of not afraid of three" that is, "fear of wet not afraid of dry," "fear not afraid of big," "afraid The characteristics of rain is not afraid of the wind, and some of the effective experience measures summarized can be used as reference for user maintenance and management of the fermentation bed.
1, increase the area of ​​housing.
For small-area pens, it is recommended to expand the pig house. If the large-scale pig house is divided into small areas, it is recommended to open the concrete partition wall so that the litter can be connected. Adopting integral housing, for each individual house to be separated, it can be separated by a moving fence, which leaves room for adjustment and can increase or decrease the area of ​​the fermentation bed of the unit housing at any time, which can effectively alleviate the shortage of fermentation space. The crisis of overloaded fermentation is easy to operate and low in cost.
2, reduce the breeding density.
If the average density of a pig is less than 1 square meter, the breeding area should be enlarged immediately, or it should be kept in separate rows to reduce the number of breeding heads per unit area, to avoid overloading the fermentation bed, abnormal work, or "Fatigue operations" to avoid unnecessary bad bed events. The technician of Jinbao Fermenting Bed Tip: The breeding density should be no less than 1.2-1.5 square feet per pig, and the breeding density can be designed even lower where the cost of construction is low.
3, to avoid excessive humidity. If the pen is leaking, measures should be taken to remedy it as soon as possible, including refurbishing the roof and covering the sides, so as to avoid inflow or infiltration of rainwater into the fermentation bed, resulting in high partial or total moisture in the fermentation bed; drinking water should be provided below the automatic drinking fountain. The "fluid channel" prevents or prevents excess moisture from flowing into the fermentation bed, avoiding anaerobic fermentation, abnormal fermentation or non-fermentation caused by excessive humidity, and failing to achieve the efficacy of exfoliating and promoting growth of the fermentation bed. In the south, due to the high groundwater level, especially when the rainy season arrives, the groundwater level rises and the surface water flow rises, which can easily cause the bottom of the fermentation bed to seep or submerge the fermentation bed. For this case, the fermentation bed should adopt a more secure ground-based structure.
4, increase ventilation measures. In general, pure high-temperature climate will not bring high temperature phenomenon to the fermentation bed; however, continuous high temperature and high humidity, together with poor ventilation of the housing, will cause abnormal or high temperature of the fermentation bed. In response to such extreme weather conditions, the Gymboree fermentation bed technicians are suggesting that you can set up fans on both sides of the house and place a ceiling fan on the top of the house to increase air circulation in the pig house, enhance air convection and enhance heat exchange. Conditional air conditioning can be properly placed in the quarters. For the high-temperature season of the entire environment, air-conditioning is used to cool down. In addition, the air ventilation function can be increased by adding skylights to the roof and adding windows to the walls.
5, increase the overturning frequency. For users who are relatively simple and unwilling to increase their investment, one of the easiest ways is to increase the number of tipping times for fermented mattress materials, such as flipping the bedding once every 2-3 days. The turbulent motion exposes the bedding of the fermentation bed to the surface layer, allowing rapid exchange of heat and moisture with the surface air. The heat is dispersed and moisture evaporates. Jinbao fermentation bed technicians suggest that for pigs that do not love arching, the litter layer should increase the number of overturns and twitches, which can quickly and effectively reduce the temperature of the center layer of the fermentation bed. For cases where the fermented mattress material is too wet due to leakage or water leakage, the wet bedding should be poured out, dried and then back into the bed.
6, effective control of feeding. For the culture mode of the fermentation bed culture, the amount of feed should be controlled. Generally, the amount of feed is reduced to about 80% to 90% of that of the ground culture, so as to increase the turnover of the pigs in the pens, which not only helps Turn over the heat, save the feed and reduce the feed ratio.

Whole-grain porridge is based on whole-grain porridge, and appropriate ingredients such as jujube, peanut, job's tears and wolfberry are added to make the porridge taste sweet and full of nutrition. Modern nutritionist points out, very rich nutrition is contained in whole grain, besides contain protein, sugar, adipose still contain the trace element such as calcium, iron, zinc, still contain dietary fiber and a variety of other nutrients.
The commonly used ingredients are: red bean, mung bean, soybean, black bean, kidney bean, millet, rice, wheat, soybean, sorghum, corn, peanut, walnut, jujube, pumpkin seed, oats, chrysanthemum, shouwu, Huaishan, Pearl barley, wolfberry and so on.
Practice brief:
1, choose the raw materials of porridge, and soak these raw materials in water for several hours;
2. Put the soaked ingredients together with other rice in an electric pressure cooker and cook for 40 minutes.
3. If other POTS are used, the time can be adjusted freely according to the situation, and the boiling glue shall prevail;
