First, the principle of chicken bed fermentation
In the nature we live in, there are many different types of bacteria that we live in. We call them microbes. These microorganisms are both beneficial and harmful. EM bacteria is a mixed group of many local microorganisms. EM bacteria have vitality and adaptability and have strong decomposition ability. Then put the bacteria into the house and decompose the chicken manure by the activity of the bacteria to achieve zero emissions and no emissions.
The digestive tract of the chicken is relatively short, and about 70% of the organic matter in the feces rate is not broken down. Well, as a manure, it has a large water content and high organic nutrients. If it is not resolved in time, it will degenerate and stink. After the chicken pulls out the faeces, the EM bacteria on the fermentation bed break down and become the bacterial protein. Chicken can also eat these bacteria protein supplements. Reduce feed intake. The broiler house generally produces odors. The vocabulary is called ammonia. After the ammonia gas is heavy, it affects the health of the chicken and induces respiratory diseases. If the airway is light, it will cause the feed intake to decrease and the egg production will decrease. In severe cases, it will lead to death. EM bacteria can effectively deodorize, fully decompose the feces, reduce the amount of ammonia in the house. The hen house will not produce bad odors. When the feces is decomposed, the liquid can effectively prevent parasite infection and reduce the incidence of chickens.
Second, chicken shed construction
1. The chicken shed is built according to its own breeding needs, with a length-to-width ratio of 5:1.
2. Build a chicken shed to consider ventilation. Adjust the indoor temperature and humidity to ensure normal temperature between 15 and 20 degrees.
Third, the production of fermentation beds
The main raw material for the fermentation bed is rice husks and sawdust, which are usually 20 to 25 cm thick. Then add 2% of the total amount, sprinkle with uncontaminated soil, and 0.3% coarse salt, because the coarse salt is rich in minerals, which is conducive to microbial reproduction and decomposition. Then press 0.5 kg per square meter to sprinkle the good strains. Pay special attention here. Don't immediately put the chicken up when the fermentation bed is done. First pre-fermentation, one week later chicks can be placed
Part IV Benefit Analysis
1. Reduce operating costs.
1, save labor. There is no need to clean the house every day.
2, save feed. Chicken manure usually takes only three days to be decomposed by microorganisms on the fermentation bed. The manure provides rich nutrition to the microorganisms, which promotes the continuous propagation of beneficial bacteria and the formation of bacterial proteins. The chickens eat these bacterial proteins and not only supplement the nutrients, but also Improve immunity. In addition, due to the addition of micro ecological preparations to feed and drinking water in chickens, there are a large number of beneficial bacteria in the gastrointestinal tract. Some of these beneficial bacteria can break down the cellulose and semi-fibrils in the straw. Such as the use of this method to breed, can increase the proportion of roughage, reduce the amount of concentrate, thereby reducing the cost of feeding. According to production practices, savings in feed are generally above 10%.
3, reduce drug costs. The chicken lives in a fermented bed and is healthier, less prone to illness and reduces medical costs.
4, litter and chicken manure mixed fermentation, directly into a high-quality organic fertilizer.
5, to improve the quality of chicken eggs, more competitive market.
V. Precautions
1, often drinking 1:200 times the EM dilution, feeding EM fermentation of feed, can break down the nutrients of the feed in advance, easy to fully absorb the chicken.
2, the density of chicken stocking should be mastered, after the dense unit of feces too much, the fermentation bed bacteria can not effectively decompose the feces, five to six per square meter.
3, EM bacteria need moist environment, observe the humidity of the fermentation bed, you can spray 1:200 times EM dilution. The humidity is controlled at about 30%.
4. Pay close attention to the activity of the probiotics: If necessary, add 1:50-fold EM broth to adjust the activity of the probiotics to ensure that the fermentation can proceed normally.
5. Prohibition of chemical drugs: The use of chemical drugs and antibiotics is prohibited in chicken houses to prevent the killing and inhibition of probiotics and to reduce the activity of probiotics.
6, must pay attention to ventilation.
7, normal epidemic prevention.
