Technology of raising chickens in fermentation bed

The technology of raising chickens in fermentation bed is an effective and more reasonable ecological technology, which not only achieves the effective treatment of chicken manure, achieves zero discharge, no pollution and no odor, but also provides the most suitable ecological environment for the healthy growth of chickens. When chickens grow in this environment, they grow fast, lay more eggs, have good egg quality and less illness, greatly save labor, water and materials, and significantly improve the efficiency of raising chickens. let's take a look at it.

Principle of raising chickens in fermentation bed

The digestive intestines of chickens are relatively short, and about 70% of the organic matter in the feces rate has not been decomposed. As a fecal treatment, it has high water content and high organic nutrients. If it is not decomposed in time, it will deteriorate and stink. After pulling out the feces, the chicken was decomposed into bacterial protein by EM bacteria on the fermentation bed. Chickens can also eat these bacterial proteins to supplement nutrition. Reduce the amount of feed. Stench is generally produced in the henhouse, which is called ammonia. When the ammonia is heavy, it affects the health of chickens and induces respiratory diseases. If the respiratory tract is light, it will reduce its food intake and egg production, and if it is serious, it will die. EM bacteria can effectively deodorize, fully decompose feces and reduce the amount of ammonia in the chicken house. The henhouse will no longer produce an unpleasant smell. While the feces are decomposed, the liquid can effectively prevent the transmission of parasites and reduce the incidence of chickens.

Construction method of chicken shed

1. The chicken shed will be built according to its own breeding needs, with a ratio of length to width at 5:1.

2. Ventilation should be considered in the construction of chicken shed. Adjust the indoor temperature and humidity to ensure that the temperature is between 15 and 20 degrees.

3. In accordance with the requirements of environmentally safe livestock and poultry houses, dust and ammonia can be effectively controlled.

Technology of raising chickens in fermentation bed

1, dilution bacteria: dry spread fermentation bed fermentation bacteria can cover chicken bed 1520 square meters per kilogram, according to 1:5 proportion with rice bran, corn meal or wheat bran without water mixed dilution, in order to increase the amount of sprinkling, evenly sprinkled into the bedding.

2. Bedding preparation: the chicken bed with an area of 20 square meters needs about 8 square meters of sawdust. Sawdust must be non-toxic, harmless, get rid of impurities and be used after drying.

3. Sow and sprinkle bacteria: you can spread it while laying, or you can mix it well and then spread it. Remember that there is no need to add water. The amount of bacteria spread in the top layer is slightly more.

4. Bedding: sawdust is required to be 40 cm thick in chicken bed. Sawdust can be partially replaced by rice husk, peanut shell and straw, which is laid at the bottom of fermentation bed. Sawdust is still used on the surface of the bed between 15 cm and 20 cm.

5. Put the chicken into the bed: you can put the chicken in after it is made. Don't wait for the fermentation to be done. If the surface is dry, you can sprinkle a little water first, so that the sheep can't afford to run.

Benefit of raising chickens in fermentation bed

1. Reduce the operating cost: raising chickens in the fermentation bed can reduce the operating cost, save labor, and do not need to clean the chicken house every day.

2. Save feed: chicken feces will generally be decomposed by microorganisms in three days on the fermentation bed. Feces provide rich nutrition to microorganisms, promote the continuous reproduction of beneficial bacteria and form bacterial proteins. Chickens eating these bacterial proteins can not only supplement nutrition, but also improve immunity. In addition, due to the addition of microecological agents in chicken feed and drinking water, there are a large number of beneficial bacteria in the gastrointestinal tract, and some cellulases and hemicellulases in these beneficial bacteria can decompose cellulose and hemicellulose in straw. by using this method, the proportion of roughage can be increased, the amount of concentrate can be reduced, and the feeding cost can be reduced. According to production practice, feed saving is generally more than 10%.

3. Reduce the cost of medicine: chickens live on the fermentation bed, so they are healthier, less likely to get sick, and reduce the cost of medicine.

4. Other benefits: after the mixed fermentation of bedding and chicken manure, it is directly turned into high-quality organic fertilizer, which improves the quality of chicken and eggs and has a competitive advantage in the market.

Matters needing attention for raising chickens in fermentation bed

1. Often drink 200 times of EM diluent and feed the feed fermented with EM, which can decompose the nutrients of the feed ahead of time and facilitate the full absorption of chickens.

2. The density of chicken stocking should be well mastered. After the density, there are too many feces per unit area, and the bacteria in the fermentation bed can not effectively decompose the feces, five to six per square meter.

3. EM bacteria need a humid environment. To observe the humidity of the fermentation bed, you can spray 200-fold EM diluent. The humidity is controlled at about 30%.

4. Pay close attention to the activity of probiotics and, if necessary, add 1:50 times EM to regulate the activity of probiotics to ensure that the fermentation can be carried out normally.

5. The use of chemicals and antibiotics is prohibited in the chicken house to prevent the killing and inhibition of probiotics and reduce the activity of probiotics.

6. Attention must be paid to ventilation and normal epidemic prevention.

Maintenance and management of fermentation bed

1. The permeability management of bedding materials: maintaining the appropriate permeability of bedding materials for a long time, that is, the oxygen content in bedding materials is always maintained at a normal level, which is one of the key factors for the fermentation bed to maintain a high decomposition capacity of feces and urine, and it is also an important means to inhibit the reproduction of pathogenic microorganisms and reduce the incidence of disease. Usually a relatively simple way is to turn the cushion material frequently, which can usually be combined with dredging feces or replenishing water to turn the cushion evenly, and turn the cushion thoroughly every other period of time (30 days), and mix the cushion layer up and down evenly.

2. Water regulation: due to the natural volatilization of moisture in the cushion material in the fermentation bed, the moisture content of the cushion material will gradually decrease, but when the moisture content of the cushion material falls to a certain level, the reproduction of microorganisms will be hindered or stopped. replenishing water regularly or timely depending on the moisture condition of the cushion material is another key factor to maintain the normal reproduction of the cushion microorganism and maintain the fecal and urine decomposition ability of the cushion material. The appropriate moisture content of the cushion material is usually 38-45%. Due to the difference of season or air humidity, the conventional way of replenishing water can use humidifying spray to replenish water, or it can be combined with replenishing bacteria.

3. Fecal management: because live pigs have the characteristics of centralized excretion of feces and urine, uneven distribution of feces and urine will appear on the fermentation bed, where the feces and urine are concentrated, the humidity is high, and the digestion and decomposition rate is slow. Only when the fecal and urine is scattered on the cushion (that is, sparse fecal management), and mixed evenly with the cushion, can the moisture in the fermentation bed be kept uniform, and the feces and urine can be digested and decomposed in a relatively short time.

4. Replenishing bacteria: regular supplement of Shenzhong EM probiotic liquid is an important means to maintain the normal microecological balance of the fermentation bed and maintain the continuous decomposition ability of feces and urine. Supplement EM probiotics once a week, spray at 1:50-100x dilution, while turning over the pig bed 20cm while spraying. Bacteria replenishment can be combined with water regulation and fecal management.

5. Bedding material updating

① usually the highest temperature section of the fermentation mattress material should be located in the lower middle of the bed, and the fermentation bed is 20 cm downwards. If the high temperature section is still shifted to the surface of the fermentation bed according to the operation rules, it means that the fermentation mattress material needs to be renewed. It can be mixed with cushions with less organic matter, such as sawdust.

The water-holding capacity of ② fermentation bed decreased, and the water content of cushion increased gradually from top to bottom. When the cushion material reaches its service life, the carbon supply capacity weakens, the decomposition rate of feces and urine slows down, water can not be volatilized through the high heat produced by fermentation, it will seep down, and the speed will gradually accelerate, the batch of pigs should update the bedding material in time after coming out of the pen.

③ enclosure has a bad smell, the decomposition ability of feces is not complete, and gradually aggravated, it needs to replenish bacteria or renew.
