What is a fermentation bed to raise pigs? Pig-raising in fermentation bed is to rapidly transform aquaculture wastes such as raw manure and urine by participating in the collaborative fermentation of padding and livestock manure, so as to eliminate odor and inhibit pests and germs. At the same time, beneficial microbial flora can synthesize padding and feces into nutrients such as sugar, protein, organic acid, vitamins, etc. which can be eaten by livestock, enhance the disease resistance of livestock, and promote the healthy growth of livestock.
Advantages and disadvantages of raising pigs in fermentation bed 1. Raising pigs in a fermentation bed has the following advantages:
1. 1 Raising pigs in a fermentation bed can reduce environmental pollution. There is no need to clean up and discharge pig manure, and a large amount of washing sewage will not be formed, so that there is no waste or excrement discharged from the pig farm, and pollutants are basically realized? Zero row? Standard, greatly reducing the pollution of pig industry to the environment.
1.2 is relatively labor-saving. Because there is no need to clean up feces, regular feeding can enhance the feeding ability of each member.
In general, 1.3 can save the cost of medicine. After pigs eat microbial bacteria, it can help digestion and improve the resistance of pigs to some extent. Moreover, the method of raising pigs in fermentation bed reduces the use of drugs and reduces the problem of drug residues in pork.
1.4 saving water and energy. Conventional pigs need a lot of water to wash, but this method only needs to provide drinking water for pigs, which can save water by 80 ~ 90%. The fermentation bed generates heat, so the pigsty does not need to consume coal and electricity for heating in winter, saving energy expenditure.
1.5 according to the publicity materials of commercial organizations, it is emphasized that feed can be saved. The principle is that feces provide rich nutrition for fungi and promote the continuous reproduction of beneficial bacteria to form bacterial proteins. Pigs supplement nutrition by feeding bacterial protein in the stuffing at the bottom of the ring, which saves some feed to some extent.
After 1.6 years of use, 1.6 padding can be directly used as bio-organic fertilizer for fruit trees and crops, achieving the effect of recycling and turning waste into treasure.
2. Disadvantages of raising pigs in the fermentation bed: Japan, South Korea and other countries are located in the sub-cold zone, and the effect is really obvious in the practice process. However, in many areas of our country, many pig farmers have found that there are still many shortcomings in the way of raising pigs in fermentation beds through experiments.
Mainly reflected in the following aspects:
2. 1 Chemical disinfectants and antibiotics cannot be used in the pigsty. If they are used, they will kill and inhibit microorganisms (so-called probiotics) or inhibit their reproduction, thus reducing the activity of microorganisms. Although the commercial organizations that promote it emphasize that the incidence of raising pigs in fermentation beds will be lower than that in traditional feeding, it is not impossible. When respiratory diseases occur in pig farms and pigs, pig-raising peers are faced with the dilemma of not using drugs. The growth rate of pigs is slow, and the survival rate, growth rate and feed reward are reduced, which is not worth the loss. In addition, it is impossible for so-called probiotics to inhibit the virus. When common viral diseases such as blue ear disease and circovirus occur in pig farms, or serious infectious diseases such as foot-and-mouth disease and swine fever, even chemical disinfectants cannot be used. It is impossible to control the epidemic simply by isolation, but once it is used, it cannot be fermented, and the virus will exist in the hotbed of the fermentation bed pig house for a long time. It is impossible to raise pigs in fermentation bed without getting sick, and the strain is very fragile at this concentration, which is not comparable to the drug-resistant bacteria produced in recent years.
2.2 The construction cost is high and the pigsty covers a large area. 100 square meter can only raise 50-70 pigs (each pig covers an area of 1.5 square meter). At present, large-scale pig raising can raise 100 pigs, but the existing pigsty can't be used, and it will cost a lot of money (3-foot thick sawn wood and miscellaneous wood) to transform it.
2.3 The cost of raising pigs may not necessarily decrease. Some promoters of the fermentation bed pig raising method emphasize that spraying bacterial liquid once can maintain the growth of bacteria for a long time. You know, the growth of bacteria is directly related to the composition and temperature and humidity of the padding. Can the relatively rough bedding composition (even the bedding composition can be adjusted according to local resources) provide suitable conditions for the growth of bacteria? Obviously not, it needs to be sprayed regularly, but the cost of bacterial liquid is very high, because the concentration requirement is relatively high, which will inevitably increase the cost. In addition, pigs have a large range of activities in the pigsty, running around consumes energy, and the feed conversion rate may be reduced.
2.4 The fermentation bed absorbs pig excrement through sawdust, rice bran and other powders, and pigs have the habit of eating. Wood chips, rice bran and other powders will enter the respiratory tract because of pig arching, causing respiratory diseases.
2.5 There are a lot of mycotoxins in the padding after fermentation, and pigs have the habit of eating. After pigs eat mycotoxins, they often cause immunosuppression, decreased resistance and decreased feed returns instead of rising.
2.6 The high temperature of pigsty in summer affects the growth and development of pigs. In Japan, high-rise pigs are raised, and many pig farms are equipped with air conditioners. However, the fermentation temperature in the pigsty with fermentation bed is too high, which is not conducive to the healthy growth of pigs in summer. Especially in the south of China, the temperature is very high. Although the surface temperature of fermentation heat dissipation is not high, the environmental temperature of pigs increases, the growth speed of pigs slows down and the feed reward decreases.
2.7 Bed surface humidity must be controlled at about 60%. Too low humidity is not conducive to microbial reproduction, which will lead to respiratory diseases in pigs, while too high humidity is harmful to parasitic diseases in pigs, which will bring eggs into the body when pigs eat hyphae, resulting in serious skin diseases.
2.8 The method of raising pigs in fermentation bed is inconvenient to transport pigs and troublesome to raise. If the advanced feeding equipment is not matched, the workload of the breeder may not be reduced.
2.9 Because the pigsty is semi-open, affected by the change of external environment, how to make strains play a higher efficiency in different climatic conditions is also a problem to be solved. Moreover, if there are too many pigs per unit area, the fermentation speed of the bed will be reduced, and it is impossible to quickly degrade and digest pig manure. According to the actual situation of our country, it is worth discussing to carry out large-scale fermentation bed pig raising method. Objectively speaking, the current mode of raising pigs in fermentation beds is more suitable for small pig farmers (farms) in northern China.
