Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an egg duck cage culture system that no water face combines intermittent type to spray.
[ background of the invention ]
China is a world large country of waterfowls, and the feeding amount and the consumption amount both account for more than 80 percent of the total amount of the world. The water surface breeding of waterfowls becomes an indestructible real reason for hundreds of years. For example, laying ducks are bred, and the traditional water breeding and natural spreading mode is continued. However, such feeding methods have the following disadvantages: 1. the water area in which the duck is put is increasingly polluted by industry and civilian use, the eating and drinking quality of the duck is poor, the death and culling rate is increased, the egg yield of each laying duck is reduced by 20%, the medicine use is increased, the feeding cost is increased, and the medicine use cost of each laying duck is increased by at least 3-5 yuan every year. 2. The pollution of the ducks to the water area causes the problem of environmental sanitation and safety; and cause epidemic diseases to spread along with the excrement through water flow, and have biological potential safety hazards. Research shows that waterfowl (ducks) are huge repositories for A-type influenza viruses, and the waterfowl (ducks) are mainly enterophilic, and the replication of the waterfowl (ducks) is mainly in large intestines rather than respiratory tracts, so that the viruses can be discharged from excrement at higher titer to pollute water areas and feeding places thereof. Waterfowl (such as ducks) not only play an important role in storing the avian influenza virus, but also become birds which are highly susceptible to natural infection, morbidity and mortality of the avian influenza virus, and can transversely infect terrestrial birds to become the infection source of the avian influenza. For example, the duck gosling plague (parvovirus) virus variant "short mouth disease" that has spread along the watershed in my province in these years. The traditional water surface grazing or water surface captive breeding mode of waterfowls faces serious challenges from biological safety systems and water resource environmental protection problems, in recent years, pollution of livestock and poultry breeding water areas is controlled all over the country, local policies for water surface feeding of waterfowls are forbidden to be issued, and the water surface feeding of waterfowls almost reaches the end.
3. The sanitary condition of the egg laying nest is poor, the excrement of the eggshell is serious, the commodity value is low, not only is dining table pollution caused, but also the influenza virus is easily spread to human through the excrement on the surface of the duck eggs, and the human health is damaged.
The water area feeding and the waterfowl non-water surface feeding become irreversible trends. The waterfowls leave the water surface, the transmission path of infectious diseases is cut off, the water source is purified, and the environment is protected; a biological safety system is constructed for the waterfowl industry, and the breeding benefit of vast waterfowl farmers in China is extremely protected. At present, cage culture of laying ducks is started in some places, but because spraying water supply is not combined, feathers are hardened and broken in the process of raising the laying ducks, the price of eliminating old ducks is influenced, and the raising benefit is reduced; some enterprises adopt cage culture and add a bath water tank to provide bath water for laying ducks, and the duck can extend to the mouth for drinking, so that the bath water is polluted by feed and nasal secretion on the duck mouth, the water is drunk by the duck, the drinking dirt cannot be separated, and the drinking water quality of the duck cannot be ensured; some enterprises adopt a water-free feeding mode of meat ducks or egg ducks by using fermentation padding and net beds, and because the fermentation beds are high in preparation cost, farmers reserve the fermentation beds for a plurality of batches for years for saving the cost, duck houses cannot be thoroughly cleaned and disinfected after each batch of ducks are eliminated, full-in and full-out cannot be realized, and the potential biological safety hazard is great.
