For enterprises that use the "zero-emission ecological pig-raising technology of fermentation bed" for pig production, its economic benefits are reflected in:
1, reduce infrastructure costs and improve land utilization. The investment in manure treatment system (such as biogas digester) which is indispensable in the traditional pig raising mode is saved, and the land utilization efficiency is improved.
2. Reduce operating costs:
(1) Save labor: it is not necessary to wash the shed every day.
(2) Water saving: water can be saved by more than 90% because there is no need to flush the shed.
(3) Save feed: Pig manure will be decomposed by microorganisms in three days on the fermentation bed, which provides rich nutrition for microorganisms and promotes the continuous reproduction of beneficial bacteria to form bacterial proteins. Eating these bacterial proteins not only supplements nutrition, but also improves immunity. In addition, because microecological agents are also added to pig feed and drinking water, there are a large number of beneficial bacteria in animal intestines, and some cellulase and hemicellulase in these beneficial bacteria can decompose cellulose and hemicellulose in straw. Using this method to raise pigs can increase the utilization rate of feed and reduce the consumption of concentrate, thus reducing the feeding cost. In addition, the living environment of pigs is comfortable, and the growth rate is accelerated. Generally, pigs can be slaughtered 10 days in advance.
According to the production experiment, the feed saving is generally above 10%.
(4) Reduce the cost of medicine. Pigs live on the fermentation bed, which is healthier, less likely to get sick and reduces the cost of medicine.
(5) Saving energy: raising pigs by fermentation bed is warm in winter and cool in summer. Floor heating, air conditioning and other equipment are not needed, which greatly saves energy. The heat generated by fermentation in summer can make the surface temperature reach about 20 degrees, which solves the problem of thermal insulation of the enclosure; In summer, the problem of hot pens can be solved simply by ventilation and shading.
3. After mixed fermentation, the padding and pig manure directly become high-quality organic fertilizer.
4, the pork quality is improved, and the pork has a competitive advantage in the market. At present, the purchase price of pigs in enterprises that raise pigs in this way is 0.4 ~1yuan/kg higher than that of ordinary pigs, while in the consumer market, the price of pig liver is several times higher than that of ordinary pigs.
5. The advantages of eco-friendly pig-raising method are summarized as follows: five provinces, four improvements, three nothing, two increases, one less and zero emissions.
Five provinces: saving water, labor, materials, medicine and electricity.
Four suggestions: improve meat quality, improve immunity, slaughter ahead of time, and improve the ratio of meat to feed.
Three noes: no odor, no fly maggots and no environmental pollution.
Second increase: increase economic benefits and increase ecological benefits.
One less: reduce drug residues in animals.
Zero discharge: pig manure and urine are all degraded in the pig house, and no sewage and feces are discharged.
