Fermentation bed duck farming technology is emerging in recent years, if useless fermentation bed duck feces excreted directly into the ground, a long time will produce ammonia stench and harmful bacteria on the duck cause great health threat, then fermented bed role is when the duck feces fermentation fermentation bed when the bed surface inside em bacteria can be decomposed manure to produce bacterial proteins for duck feed, inhibit the growth of harmful bacteria and thus to create a useful duck habitat, prevent the occurrence of various diseases to enhance the resistance of duck, and now from the following major advantages in terms of the benefits and methods of fermentation bed duck em a bacteria, regulate animal gastrointestinal balance and promote nutrient absorption, improve feed utilization. 2, to improve the amount of meat, eggs and other animal products, improve the quality of livestock products. 3, to improve the body's non-specific immunity, improve the survival rate and uniformity. 4, to improve the body's ability of anti should reduce production losses due to transfer group, vaccination, temperature, etc., causing upheaval. 5, fermentation roughage and meal and bad residue feedstocks, reduce toxin levels, reduce costs and improve flexibility. 6, improve digestion and absorption of feed utilization, improve production performance, contains a variety of beneficial microorganisms live bacteria, establish animal intestinal microflora balance, animal feed nutrients for which complete absorption and utilization, make use of protein, energy, minerals, rate of 95%, greatly enhance absorption and utilization of roughage, thus reducing feed costs, the long-term use can save 10-15% of the production of feed fermentation bed duck species diluted em, 10 kg of water to a boil when the temperature drops time will be about 20 degrees inside the sealed fermentation broth poured in 3-5 days you can use a bottle with 10 kg of bacteria may be able to do the fermentation broth mattress 5 square material selection generally use sawdust and rice shell generally accounts for 80% -20% sawdust, rice husk, 20% -80% if none of these substances can also use straw and other litter were instead. Adding nutrients to a square bed fermentation nutrients needed cornmeal or rice bran 1 kg, 1 kg of deep soil, and some salt. After mixing of nutrients and bacteria, if not urgently closed fermentation two days better, will marinated nutrients, salt and stuffing evenly mixed stew heap fermentation to Hold the fingers but not dripping watermark appropriate, if high temperature fermentation can be tiled, summer 3-5 days, 7-10 days of winter, and finally, after the surface evenly sprinkle the soil, two days to the ducks reared. Note fermentation bed duck daily management 1, regular consumption of 1: 200 dilution fold em, feed em fermented feed, feed nutrients can be decomposed in advance, easy to fully absorb the duck. 2, duck stocking density to master, secret unit area after much manure fermentation bed fecal bacteria can not effectively break down every five to six meters. 3, em bacteria need a wet environment, observe the fermentation bed humidity, can be sprayed 1: 200 fold dilution em. Humidity at about 30%. 4, pay close attention to the activity of bacteria em: 1:50 fold em again join em bacteria modulate the activity of bacteria, if necessary, to ensure that the fermentation can be carried out normally. 5, the prohibition of chemical drugs: prohibit the use of chemicals in the duck and antibiotics to prevent and suppress em kill bacteria, so that the active em reduce bacteria. 6, we must pay attention to ventilation. 7, normal vaccination.
