At present, the domestic chicken industry has gradually formed a pattern of excellent varieties, full price of feed, and large-scale feeding. However, most chicken producers believe that nowadays chickens are more and more difficult to support, and the more they raise, the more they will not raise them. It is estimated that the direct economic loss caused by the death of chickens in Shandong each year amounts to more than 4 billion yuan. Why is the chicken breed improved, the feed nutrition is full price, the quality of vaccines and veterinary medicine is good, the chicken production technology is improved, and the chicken is still raised? The answer is: frequent epidemics plague the healthy development of the chicken industry.
The deficiency of chicken environment and facilities is a hidden danger of disease
Compared with the developed countries, the chicken industry in China has gradually narrowed the gap in its breed, feed, and disease control technologies, and the gap between the environment and facilities is still quite large.
For example, at present, more than 80% of commercial broilers in northern China are kept in plastic greenhouses or simple chicken coops. The winter is not warm, the summer is not heatstroke, the space is small, and ventilation is poor. In this type of chicken house, the survival rate is Unable to guarantee. The environment and facilities of broiler breeders and layer chicken hen houses are also very simple and the layout is extremely unreasonable, resulting in difficulty in sewage discharge, serious site pollution, and more flies; in summer, heat death chickens often appear, fertility rate and egg production rate. Significantly lower; cold winter chicken house, respiratory diseases occur from time to time.
According to incomplete statistics, at present about 90% of the domestic chicken farm design is not reasonable. Using unreasonably designed chicken farms, the best breeds, feeds, and pharmaceutical vaccines cannot achieve the desired level of production. Therefore, the lagging environment and facilities are the key factors causing the outbreak of disease. As a chicken producer, the money should be used to transform the chicken house to create a comfortable and comfortable environment for chickens. Specifically consider the following points:
The layout of the house
The chicken house should be built away from densely populated villages or towns. The farming community should not be implemented. Intensive construction has brought great difficulties in controlling infectious diseases. Some local governments have imitated the construction of animal husbandry plots under the agricultural plan. Both of them have experienced serious horizontal transmission of diseases and diseases and caused huge economic losses. To this end, we advocate decentralized construction.
The chicken farm must have good sewage conditions. The excrement and sewage must be transported and removed in time. Prevent the contamination of feces and sewage around chicken farms.
The distance between henhouses, broiler breeding, bred and egg production areas must be clearly divided to prevent cross-infection.
The structure of the hen house strives to be reasonable. It mainly includes ground treatment, ceiling setting, wall height, thickness, door and window design, etc., making it resistant to erosion, good heat insulation performance, spaciousness, and good ventilation performance.
Building specifications
The breeder houses are mainly black houses, and the high requirements are 2.6 to 2.8 meters, the width is 9 to 12 meters, and the length is 70 to 100 meters. The closed chicken house had air inlets on the walls on both sides of the entrance, and wet curtains were installed. Fans were installed on the other side of the walls and used negative pressure ventilation. The size of the fan and air inlet is determined by the number of chickens in stock. Commercial chicken houses are mainly windowed and closed (black) houses. The height of the chicken house is not less than 2.6 meters and the span is 9 meters to 12 meters. The length is determined according to the capacity of each building.
Environmental Facilities
Insulation facilities mainly include coal-fired hot blast stoves, gas hot blast stoves, and electric brooding umbrellas or brooders, accelerating the abolition of traditional stove heating methods.
Cooling and Ventilation Facilities In recent years, the summer temperatures have become higher and higher. Therefore, the use of wet curtains to reduce temperature, vertical ventilation is the most effective way to reduce temperature. This method can reduce indoor temperature by 5 °C ~ 6 °C in the summer, not only reducing the number of dead chickens in the heat stroke, but also can improve the fertilization rate of breeder 5% to 10%.
Nipple drinkers are used in drinking water facilities, which not only saves water, but also ensures drinking water hygiene and reduces the occurrence of E. coli disease. At the same time, due to less water leakage, the manure is not fermented, the ammonia concentration of the house is reduced, and the fly is also greatly reduced.
Feeding facilities can use automatic feeding lines to reduce feed waste and artificial contamination opportunities.
Cage-raised chickens can use automatic scraping plate device to manually clean the manure in the chicken house, and the environmental pollution is serious. The use of automatic scraper plate device can effectively solve the problem of fecal pollution, but also can increase the amount of per capita feeding.
Feeding methods Layer chickens and egg breeders are kept in cages or high bed scaffolds. Broilers are reared on 2/3 scaffolds and 1/3 litter. Commercial broilers are fed with thick litter or scaffolding (net beds).
Feeding scale
Chicken farms should gradually transition from small-scale decentralized rearing to large-scale, intensive farming. The number of farms should be reduced to expand the size of individual farms.
Accelerate the pace of renovation of environmental facilities
Enhance public opinion guidance
Should change from the concept, vigorously publicize the importance of the transformation of the environment and facilities, so that people are fully aware that the money spent on chicken house reconstruction is more economical and more strategic than using money to buy medicine for chickens. Chicken products cause serious drug residues.
Put the acceptance of the good chicken farm
When accepting the breeder farm, the proportion of the environmental facilities shall be increased. If it does not meet the standards, it shall be ordered to reform or suspend. The results of the acceptance shall be announced by the media. In addition, the construction of some large-scale chicken farms must be well-documented and approved. Individuals who want to build chicken farms must apply in advance, and the animal husbandry authorities must agree before they can be constructed to prevent adverse consequences after they are completed.
Accelerate the formulation of residual drug sales standards for both inside and outside chicken products. At present, there is no question about the drug residue and pollution levels of domestic chicken products. Drug residues seriously endanger people's health and cause a lot of environmental pollution. To this end, it is recommended that relevant departments expedite the establishment of domestic standards for drug residue in chicken products, and strictly quarantine the quality of chicken products sold in restaurants and on the market, so that poor products have no market, and guide chicken farmers to improve the health level of chickens by revising aquaculture facilities. To reduce medication.
Do a good job of standardization of the chicken house
It is recommended that the competent animal husbandry authorities organize relevant scientific and technical personnel to carefully design and make drawings of chicken houses suitable for different regions, different types, and different investment sizes to avoid investment risks and achieve the purpose of optimizing production.
Development to a standard family farm or farmstead
The main body of chicken production in China will be a professional large-scale farm or farm in a certain period of time in the future. The state and local governments should encourage and support farmers with certain conditions to establish a financial system and enterprise management system, establish a standard family farm (or farm), and promote the development of the farmers' households in the direction of normalization. At the same time, the production structure of “company + farmer†has been strengthened, from the loose type to the compact type in the past, and the core company has centralized the bank to provide loan guarantee for its peasant households. Accelerate the improvement of the current backward feeding methods and simple conditions. For some small breeders who have low breeding techniques, few in number and poor returns, they do not give support and they are naturally eliminated. In short, chicken production in the future is in a meager operation, and it is only profitable to adopt large-scale breeding and standardized management.
In short, the environment of the sheds is simple, the disease of the flock is difficult to control, and the management is no better. If we provide a good and comfortable standardized chicken house for chickens, the incidence of disease will be significantly reduced, the genetic potential of the species will be fully realized, the production cost will be reduced, and the economic benefits will be significantly improved. In the era of low profit management in the chicken industry, it has strong competitiveness. I hope people will pay close attention to this.
