The pigs in the fermentation bed are involved in the cooperative fermentation of litter and livestock manure to rapidly transform the culture wastes such as raw manure and urine, eliminate odor, and suppress pests and pathogens. At the same time, the beneficial microbial fermentation bacterium group can synthesize litter and feces. Nutritional substances such as sugars, proteins, organic acids, vitamins, etc., which are consumed by livestock, enhance the disease resistance of livestock and promote the healthy growth of livestock.

Fertility bed pigs

The fermentation bed pig raising technology has the following advantages:

Fermenting pigs can reduce the pollution of the environment. There is no need to use sweeping emissions for pig manure, nor does it generate large amounts of flushing water, so that no waste or excrement is expelled from pig farms. Basically, the “zero discharge” standard for pollutants is achieved, which greatly reduces the pig industry. Pollution of the environment. Relatively saving people power. Because it does not require excrementation, keeping it as usual can increase the number of feeds per person. Under normal circumstances, drug costs can be saved. After the pigs eat microbes, they can help digestion and, to a certain extent, increase the resistance of the herd. And the fermentation bed pig-raising method reduces the use of drugs while reducing pork's drug residue problems. Save water and energy, conventional pigs need a lot of water to wash, but this method only needs to provide the pig's drinking water, can save 80~90%% of water; the fermentation bed generates heat, the pighouse does not need coal consumption in winter Electric heating, save energy costs. According to the promotion materials of commercial organizations, it is emphasized that the feed can be saved. The principle is that the feces provide rich nutrition to the fungi, and the beneficial bacteria are continuously propagated to form bacterial proteins. The pigs only supplement the nutrients in the filling material of the ring bottom and supplement the nutrition. Therefore, to a certain extent, it can save a part of the feed. After being used for one and a half years, the litter forms bio-organic fertilizer that can be used directly for fruit trees and crops to achieve the effect of recycling and turning waste into treasure.

Disadvantages of fermented bed pigs:

Fermentation bed pigs can not use chemical disinfectants and antibiotics in pig houses. If used, they will kill and inhibit microorganisms (so-called probiotics), or inhibit their reproduction. This will reduce the activity of microorganisms, even though they are promoted by commercial establishments. Emphasizing that the disease rate of pigs in fermentation beds will be lower than that of traditional breeders, but it will not happen. When pig farms and pigs develop respiratory diseases, the pig-racers face a dilemma: without drugs, pigs grow slowly and survive. Rate and growth rate, feed remuneration are reduced, gains are more than gains, in addition, the so-called probiotics can not inhibit the virus, when the farm has blue-ear disease, circovirus and other common viral diseases, or foot-and-mouth disease, swine fever and other potent infections In times of illness, even chemical disinfectants cannot be used. It is not possible to control the epidemic only by isolation. However, once the drug is used, it cannot be fermented any longer, and the virus will remain in the warm bed of the pig-raising pig house for a long period of time. Will suffer heavy losses. Pig-raising pigs in the fermentation bed are not unlikely to get sick. The strains are very fragile at this concentration. Compared to the pig-raising bacteria caused by pig breeding in these years, it is not an opponent at all.

The construction cost is high and the piggery has a large area. Only 50-70 pigs can be raised on 100 square meters (each pig covers an area of ​​1.5 square meters). Currently, 100 pigs can be raised for large scale pigs. Can not be used, a large amount of money to transform (to pad 3 feet thick sawn wood, but also to be mixed wood). The fermentation bed absorbs the pig's excrement by powdery substances such as sawdust and rice bran, and pigs have a habit of arching. Powders such as sawdust and rice bran can enter the respiratory tract due to the pig arch food, causing respiratory diseases.

After fermentation, there is a large amount of mycotoxins in the litter. Pigs have the habit of arching food. After the pigs only eat mycotoxin, they often cause immunosuppression, decreased resistance, and no increase in feed remuneration.

The temperature in summer pighouse is too high, which affects the growth and development of pigs. Japan is a high-level pig farm. Many pig farms are equipped with air-conditioning, while fermentation beds produce pigs that are too warm to ferment, and summer is not conducive to pigs. Healthy growth. Especially in the southern regions of China, the temperature is already high, although the surface temperature is not high, but the temperature of the pig's environment is increased, the growth rate of the pig is slow, and the feed repayment is decreased.
