  1 Overview of production and trade of layer industry in 2020
  1.1 International aspects
  1.1.1 Production
   The number of layer hens in the United States decreased slightly. At the end of 2020, the number of layer hens in the United States was 326 million, a decrease of 4.5%over the same period of the previous year, failing to maintain the growth trend since 2015. From January to July, the feed cost of laying hens dropped from 31.78 cents per dozen eggs in the same period of 2019 to 30.11 cents, a decrease of 5.25%.

In 2020, EU egg prices fell by 15.4%over the previous year, and egg consumption increased by 1.1%over the previous year. Among the main producing countries, France’s egg production in 2020 is approximately 943,000 tons, an increase of 14%over 2019; Germany’s egg production in 2020 is 937,000 tons, an increase of 2.4%over 2019; Spain’s egg production in 2020 is 891,000 tons, compared with 2019 The same; Italy’s egg production in 2020 is 801,000 tons, 2%less than in 2019.
  1.1.2 Trade
   US egg exports are growing. From January to June 2020, U.S. egg exports increased by 17.6%over the same period in 2019. Among them, processed egg exports increased by 41.14%over the same period last year, and in-shell egg exports fell by 4.78%. U.S. egg exports account for 2.86%of egg production. From January to June 2020, the U.S. in-shell egg exports to China accounted for 42%of the total in-shell egg exports. The other major export regions were Mexico, Canada, the rest of the Americas, and the Middle East, each accounting for the total U.S. in-shell egg exports. 31%, 11%, 8%, 6%. Exports of processed eggs accounted for 1.97%of the total output of the United States. The main export regions of processed eggs were Canada, Mexico, and Japan, which accounted for 25%, 24%, and 19%of the total exports of processed eggs, respectively.
   From January to October 2020, the EU (excluding the United Kingdom) exported 194,000 tons, a decrease of 4%over the same period last year. Japan, Switzerland and Israel are still the three major egg export target countries of the EU (excluding the United Kingdom), accounting for 28.8%, 17.9%, and 5.7%of the EU (excluding the United Kingdom) total egg exports respectively. Other major export targets are Thailand and South Korea, which accounted for 4.1%and 3.8%of EU egg exports respectively.

Argentina is the EU’s third largest source of egg imports, accounting for 7.7%of the EU’s egg import market share. The fourth and fifth places are Albania and Norway, with a market share of 4.9%and 3.5%respectively.
  1.2 Domestic aspect
  1.2.1 production
  ① Overcapacity of laying hens. One is that the production capacity of layer breeders remains in excess. The average stock of ancestral layer breeders is still much higher than the market demand of 360,000 sets, and the supply of parental and commercial chicken fry is guaranteed. According to the monitoring of the China Animal Husbandry Association, the average stock of ancestral-generation breeders from January to December 2020 has decreased by 6.0%year-on-year, but remains at more than 500,000 sets, which can fully meet the needs of the parent and commercial layer breeding market; 1 -In December, the average stock of parent-generation breeders increased by 6.0%year-on-year, and the sales of commercial chicken seedlings decreased by 0.4%. The second is to accelerate the adjustment of production capacity reduction for commercial laying hens. Due to the continued substantial profitability of layer breeding from 2018 to 2019, the farms (households) are enthusiastic about breeding. Affected by the craze of replenishment in 2019 and the new crown pneumonia epidemic in 2020, the stock of laying hens in the first half of 2020 is at a historic high, and the price of eggs is running at a low level. After the live poultry trading was released in May, the farms (households) eliminated the laying hens. , The production capacity of laying hens is obviously reduced.
  ② The price of eggs and the price of eliminated chickens have both dropped significantly year-on-year. Egg prices remained high in 2018 and 2019, both higher than the average egg price in the past five years. In 2020, except for January, the egg price will continue to be below the average egg price in the past five years; the price of eliminated chickens will be in 2016 and 2019 The year is higher than the average of the past five years, and in 2020 it will be higher than the average of the past five years from January to May, July and August. Affected by the surplus of laying hens, the price of eggs and the prices of eliminated chickens have dropped significantly year-on-year. According to the designated monitoring by the Ministry of Agriculture and Rural Affairs, the average egg price from January to December 2020 fell by 22.8%year-on-year, and the egg price in December fell by 12.4%year-on-year. The average price of chickens eliminated from January to December fell 15.8%year-on-year, and the price of chickens eliminated from December fell 15.4%year-on-year.
  ③ Feed costs and feeding costs increased slightly year-on-year. With the implementation of various policies for the stable production and supply of live pigs, the live pig stock has gradually recovered to more than 80%of the stock level at the end of 2017, which has driven the price of feed such as corn and soybean meal to recover, and the cost of layer breeding has increased. According to designated monitoring by the Ministry of Agriculture and Rural Affairs, the average feed cost and breeding cost of laying hens from January to December 2020 both increased by 5.8%year-on-year. The cost of feeding and feed per kilogram of eggs has increased year-on-year except for January and February.
  ④Laying hen farming is at a loss throughout the year. In 2018 and 2019, the efficiency of layer farming increased significantly. In 2019, there were more farm households to fill up the stock, which caused the stock of layer hens in the first half of 2020 to reach a record high. At the same time, the new crown pneumonia epidemic caused an oversupply of eggs and low egg prices. The efficiency is poor, and the trend of capacity reduction has been formed. In October, the stock and egg production decreased year-on-year. With the improvement of the situation of the new crown pneumonia epidemic, the favorable situation of increased consumption and decreased output appeared in the fourth quarter, but the cost of feed increased, and the annual breeding efficiency was at a loss. According to fixed-point monitoring by the Ministry of Agriculture and Rural Affairs, the cumulative chicken profit from January to December 2020 has dropped by 102.3%year-on-year.
  1.2.2 Trade
   From January to July 2020, my country’s egg exports amounted to US$105,600 million, which was lower than the US$1153.2 million in the same period in 2019. From the perspective of egg exports from January to July 2020, January to March was compared with 2019. The year-on-year decline was even greater. In April, it began to show recovery growth, but overall, egg exports were lower than the same period in 2019. Egg imports are also showing a downward trend, with egg imports in 2019 and January-July 2020 at US$110,000 and US$40,000 respectively. Judging from the egg trade from January to July 2020, the export value of processed eggs and fresh eggs was US$43.9 million and US$607.6 million, respectively, accounting for 41.79%and 57.84%of egg exports. The import of eggs is mainly for breeding poultry eggs, and the import value from January to July of 2020 is about 40,000 US dollars. From January to July 2020, my country’s egg products were exported to 41 countries and regions. Among them, the top 5 were Hong Kong, Macau, Japan, the United States and Singapore, which is basically in line with the situation in the same period in 2019. Hong Kong, China remains the largest egg export market in Mainland China.
  2 my country’s technology research and development progress in laying hen industry in 2020
 
  2.1 Genetic improvement technology
   2.1.1 Layer SNP chip”Fengxin No. 1″ upgrade
   Through genome-wide association analysis (GWAS) research results, chicken QTL database, OMIA database, and whole genome resequencing data of the target species, update the important QTL segment sites, important quality and economic trait sites in the chip. On the one hand, the replacement of chip sites can improve the efficiency of chip use and obtain more available genomic information, and the chip sites can also be adjusted according to actual breeding needs to improve the accuracy of selection.
  2.1.2 Identification of candidate genes for important economic traits
   Use GWAS to identify candidate genes for bone growth traits, located on chromosomes 1, 2, 27, including HTR2A, LPAR6, CAB39L, etc.; identify candidate genes RABGAP1 that are significantly related to eggshell strength and eggshell ratios , LMBNL3 and TMEM117. Researched out the regulation mechanism of chicken embryo development-diapause-activation process and identified key genes, such as PPP1R8 and IRF1. According to the transcriptome sequencing of different grades of follicular development, AMH, FSHB, SORL1 and other genes were screened, which play a key regulatory role in follicular development. Through protein interaction network analysis (PPI), 8 key candidate genes that are significantly related to peak egg production and reproductive hormones in Gushi chickens were screened and identified, mainly involved in the secretion and regulation of gonadotropin-releasing hormone (GNRH), follicle-stimulating hormone (FSH) and luteinizing hormone (LH) synthesis, negative feedback regulation of estrogen and progesterone, inhibition of PRL synthesis, promotion of ovulation and other functions. It was identified that PCNT and DDB2 proteins can be used as potential immune markers after ALV-J infection with different genetic backgrounds.
  2.1.3 Analyze the relevant mechanism of action
  Using ATAC-seq technology to sequence and analyze all open regions in genomic DNA, it is found that the apparent modification of female chicken embryo gonadal asymmetric development; construction of circRNA-miRNA-mRNA molecular regulatory network for chicken follicular development; Study the expression patterns of competing endogenous RNAs (mRNA, lncRNAs, circRNAs and miRNAs) in the ovarian tissues of purebred and hybrid populations and found that non-additively expressed RNAs have pathways related to lipid metabolism, energy homeostasis and oxidative stress These processes control the growth and atresia of pre-grade follicles in hens, further determine the efficiency of egg production and affect the heterosis of egg production. Through transcriptome sequencing and proteomics technologies, the expression profile of chicken sperm RNA and its status A new function in sperm motility regulation has found that oxidative stress damage can cause sperm acrosome and plasma membrane damage, mitochondrial dysfunction, and lead to low sperm motility. The blood triglycerides, total cholesterol, fatty acid binding protein 4 (FABP4) and lipoprotein lipase levels of FLHS layers were detected, and it was found that the plasma level of FABP4 was positively correlated with the fatty liver grade of the late laying hens, indicating that FABP4 may be Potential diagnostic indicators of FLHS.
  2.2 Nutrition and Feed Technology
  2.2.1 Establish an analysis model of a small near infrared feed analyzer
   At present, the finalization of the miniaturized instrument has been completed, and the modeling of the finalized instrument has been completed in the corn and soybean meal samples. At present, the use of a small near-infrared feed analyzer can detect three conventional feed indicators such as moisture, dry matter, and crude protein, which can provide a rapid analysis platform for layer breeding companies and small and medium-sized feed companies, and provide a powerful way to achieve”test before eat” Guarantee.
  2.2.2 Establish the key technology of nutrition regulation for high-quality egg production
  ”The research and application of the key technology of nutrition control for high-quality egg production” was evaluated by the Chinese Society of Agriculture as”International Advanced Level” (Zhongnong (Evaluation) Zi [2020] No. 3); Key technologies for regulation and control have been approved by the relevant departments and bureaus of the Ministry of Agriculture and Rural Affairs, and have been selected by the Chinese Society of Agriculture as the”2020 China’s Agricultural and Rural Significant New Achievements in Science and Technology”. This achievement has outstanding effects in improving the strength of eggshells, the consistency of egg whites, and the nutritional content of egg yolks. It has provided strong scientific and technological support for the transformation and upgrading of the layer industry and healthy and sustainable development.
  2.3 Disease prevention and control technology
  2.3.1 Scientific burden reduction technology for chicken immunity
  The essence of the”scientific burden reduction” of chicken flock immunity is to follow the physiological laws of the body, the laws of disease occurrence and the laws of antibody growth and decline, combined with disease monitoring data, rationally formulate and optimize immunization procedures, reduce the number of vaccinations, and improve the performance of laying hens. At present, this technology has been applied in various comprehensive test stations of the national layer industry technology system, and has been further promoted to breeding enterprises outside the system, and has achieved remarkable results.
  2.3.2 Comprehensive prevention, control and purification of Mycoplasma synovialis (MS) infection in chickens
   MS infection is an important infectious disease endangering the poultry industry in my country. Based on 3 consecutive years of field and laboratory research, technical solutions for purification and control of MS infection under different conditions have been determined. For ancestral chickens, a comprehensive prevention and control plan is mainly adopted with biosafety measures and combined immunization with live vaccines and inactivated vaccines. For parental generation chickens, if they come from a negative ancestral generation chicken flock, the same protocol as the ancestral generation chicken is adopted. If there is low-level infection or vertical transmission, sensitive drugs should be used to assist control in a timely manner on the basis of the ancestral generation chicken program combined with the test results . For commercial chickens, according to the strategy of “one policy, one policy” combined with the results of epidemiological surveillance, sensitive drugs are used for prevention at the time when there is a high risk of infection during the brooding period, so that the positive rate of MS infection in chickens is maintained at a low level .
   2.3.3 Development of avian infectious bronchitis live vaccine (LDL-T strain)
   Since 2009, my country’s nrTW type I infectious bronchitis virus has become an important virus that harms China’s chicken industry, and the existing commercial vaccines have poor cross-protection effects. Therefore, a new live infectious bronchitis vaccine (LDL-T strain) against the nrTW I strain was developed, and the new vaccine was discovered through laboratory tests such as seed virus identification, laboratory trial production, quality research, and intermediate trial production. It has the characteristics of good safety and high protection rate.
  2.4 Production and environmental control technology
   Optimize and integrate the technical equipment of the new-type perch three-dimensional free-range breeding system for both breeding and laying period of laying hens. Combined with my country’s cage-bred brooding mode, the integrated three-dimensional free-range breeding equipment for breeding eggs is developed to facilitate the operation of immunized chickens. The structure and feeding space of the free-range perch system have been further optimized; a set of lighting system suitable for the new three-dimensional free-range perch system of laying hens has been designed to control the real-time transmission of data, adjustable light intensity, fade in and fade out, and spectrum control , Illumination uniformity design and no flicker feature, can meet the high-temperature, high-humidity and dusty layer production system of high-efficiency and healthy production of light elements. The effects of different breeding modes and group breeding densities on the growth and development of laying hens and the effects of different breeding modes on the production performance of laying hens during the laying period are studied. The perch breeding system has higher egg production efficiency and earlier than the laminated cage system. Reaching the egg production peak period and maintaining the egg production peak time for a long time provides technical support for promoting the efficient, green and healthy transformation and upgrading of my country’s layer breeding methods. According to the cage breeding technology of layer breeders, a study on the optimization of facility equipment parameters has been carried out, and a set of optimized process parameters of the cage cage equipment has been formed:① 2 laying nests with different parameters are recommended in the cage (A:90 cm× 40 cm×60 cm; B:70 cm×52 cm×60 cm); ②It is recommended to set abrasive belts as the claw grinding pad on the back of the trough in the cage (length×width:50 cm×10 cm); ③ Artificial grass mats are set in the laying nest as floor coverings and 30 lx LED white light and blue light are used as the induction light source at the initial stage of production. The optimization of process parameters reduces the death rate of breeders by 7%and reduces the behavior of breeders. Fear and blood corticosterone content, increase the frequency of mating behavior and fertilization rate, improve the welfare of chickens, provide a basis for the promotion and application of the optimization of the cage breeding mode of layer breeders.
  2.5 Egg quality control and processing technology
  2.5.1 Developed a production technology to improve the emulsification of egg yolk
  The liquid egg yolk is sensitive to heat, and it is easy to denature and solidify if it exceeds 65°C, resulting in a significant decrease in its emulsification performance, which greatly limits the application of liquid egg yolk in the food industry. The enzyme modification method not only improves the heat-resistant temperature of the egg yolk liquid, but also reduces the adverse effect of the heat sterilization temperature on the emulsification properties of the egg yolk liquid, so as to achieve the purpose of improving the emulsification of the egg yolk liquid.
  2.5.2 Developed nutrition chicken soup preparation technology
  Using the elimination of laying hens as raw materials, combining heat treatment, superfine grinding, microcapsule embedding, biological enzymatic hydrolysis, Maillard thermal reaction and other technologies, developed ultra-fine chicken bone meal, chicken fat powder, defatted chicken protein powder, Concentrated chicken broth seasoning. According to the different dietary needs of the elderly, children, women and other people for calcium, protein and other nutrients, a healthy chicken soup formula with certain nutritional fortification and functional characteristics is formulated in proportion, which greatly increases the comprehensive utilization rate of eliminated layers.
  2.5.3 Developed egg yolk and chicken flavor food ingredients
   Based on the traditional egg butter extraction process, the ethanol extraction method is combined with the enzymatic method to improve efficiency. The flavor components of low-cholesterol egg butter before and after oxidation were analyzed and compared by flavor gas ion migration chromatography (GC-IMS) technology. It was found that the flavor components in oxidized egg butter were far more than egg butter, which enriched the aroma level of egg yolk products and expanded to Development, utilization and technological improvement of diversified and personalized egg products such as meringues, mayonnaise, egg yolk cookies and other products.
  2.5.4 Developed compound antibacterial agents such as natural antibacterial agent lysozyme
  Using the lysozyme extracted from the egg white, and the liquor, which is one of the common ingredients of dry-cured sausages, form a compounding agent, which is used to control the pathogenic bacteria Staphylococcus aureus and its enterotoxin in dry-cured sausages and to control the quality of sausages. improve.
  2.5.5 The effect of three kinds of antibiotics administered in the reserve period of laying hens on the antibiotic residues in eggs during the pre-laying period was studied
   During the growing period 103 days of administration, florfenicol drug residues can still be detected in eggs laid by 130-day-old layers, and enrofloxacin can still be detected in eggs laid by 150-day-old layers Residues of doxycycline and doxycycline indicate that antibiotics should be stopped after 70 days of age.
  3 Problems in my country’s layer industry in 2020
 
  3.1 Emergencies such as the new crown pneumonia epidemic have a great impact on industrial development
   The sudden new crown pneumonia epidemic in 2020 will have a major impact on the development of the layer industry. One is to disrupt the production plan of the breeder farm. The transportation of chicks, eggs, feed, etc. is blocked, and the farmers are facing difficulties in supplying materials and capital turnover. They cancel the contract for the chicks and the breeder farm is in a state of reduced production or suspended incubation. Second, it has affected the transportation and circulation of feed. As the prevention and control of the new crown pneumonia epidemic requires traffic control, large and medium-sized feed factories store more main raw materials. Raw materials such as corn and soybean meal can be maintained for a period of time, but the transportation of compound feed is restricted. Since raw materials such as corn and soybean meal are not stored in self-proportioned chicken farms, they will seriously affect production and operation when they are exhausted. The third is the impact of egg sales. The purchase of eggs by dealers has decreased and the prices have been low. Small farmers have encountered difficulties in capital operation, and sustainable production has been affected. There are still great uncertainties in emergencies such as the new crown pneumonia epidemic, and it is particularly important to prepare a response plan in advance to ensure the normal development of the layer industry.
  3.2 The replenishment and expansion of hens are irrational, and the fluctuation of egg prices will inevitably cause economic losses
  According to research, the egg market price fluctuates in a period of about 3 to 4 years, which makes layer breeding generate different profitability every year. The size of the profit margin drives the main body of breeding to adjust production in the next production cycle to continuously adapt to changes in egg market prices. Since August 2016, laying hen farming has continued to be profitable; in addition to the small profit space in 2017, layer farming has made substantial profits in 2016, 2018, and 2019. In particular, due to the impact of the African swine fever epidemic in 2019, the price of eggs was all Maintained a high level during the year, and the profitability of breeding increased significantly. Under the favorable conditions of this market, the enthusiasm for breeding of the majority of employees is high, and they continue to make up for the expansion of production, step by step to increase the overall production capacity of the layer industry, resulting in a serious overcapacity situation in 2020, and then the egg price continues to decline, maintaining low operation throughout the year. Laying hen farming is losing money.
  3.3 No-antibiotic breeding has a long way to go
   With the improvement of people’s living standards and food safety awareness, the general trend of “prohibition of resistance” at the feed end and “reduction and restriction of resistance” at the breeding end has been determined, but the total amount of antibiotics used in the breeding process is in the early stage of “prohibition of resistance to feed” It may not be reduced, and the cost of breeding will increase. It is understood that the small and medium-sized farms lack mature anti-antibiotic solutions, and the hygienic conditions and management level of the farms are not ideal, the incidence of animal diseases is still high, and antibiotics have to be used for treatment. Some farms have treatment drugs. A certain increase. However, the total amount of antibiotics used in the first three years after the EU announced the prohibition of feed resistance did not decrease. Therefore, a systemic alternative solution with good effect, low side effects and high cost performance is the key to whether the anti-resistance policy can be truly implemented. There is still a long way to go in the future. Banning resistance and reducing resistance is a systematic, strategic, complex, and long-term project, and it cannot be achieved by a single path.
  4 Development trend of laying hen industry in 2021
  4.1 The stock of laying hens is gradually reduced, and the supply of eggs is stable
  According to the tracking and monitoring of China Animal Husbandry Association, the source of ancestral layer hens is currently guaranteed, and it can provide enough chicken fry for commercial layer hen breeding. According to the fixed-point monitoring by the Ministry of Agriculture and Rural Affairs, from the perspective of the stock of commercial laying hens, due to the year-on-year decrease in the cumulative replenishment of chickens from January to December 2019, the cumulative increase in the number of eliminated chickens, and the maintenance of low egg prices and eliminated chicken prices. Chicken breeding continues to suffer losses. In 2020, the stock of layer hens will be reduced steadily, and capacity reduction will accelerate. Production capacity will reach a reasonable level in the first half of 2021, and practitioners will return to rational breeding. As the stock of live pigs recovers, the egg replacement effect will weaken, and egg consumption will also decline. A moderate reduction in the stock of laying hens can still meet market demand.
  4.2 The egg price runs at a low level, and the profitability of breeding is small
   In the second half of 2020, the adjustment of layer production capacity structure will accelerate, but the stock of layer hens in the fourth quarter will remain at a high level, and the supply of eggs will be sufficient. With the promotion of consumption during the Spring Festival, egg prices are expected to rise slightly before the Spring Festival in 2020. Later, egg prices will fall. With the gradual return of the live pig stock to the normal level, the consumption demand for eggs and eliminated laying hens has weakened, and there is a large downward space for egg prices throughout the year. Under normal circumstances, the egg price and the price of eliminated chickens will remain low in the first half of 2021; in the second half of the year, driven by the Mid-Autumn Festival, National Day and other festivals, egg prices will rise, but the room for increase is limited. It is expected that the annual breeding benefits will be average. The profit margin is limited.
  4.3 Expand egg marketing channels and develop online sales model
   In the first half of 2020, affected by the high stock of layers and the prevention and control of the new crown pneumonia epidemic, the egg market has been in a long-term downturn, which has promoted the layer industry to expand marketing channels and gradually move from the traditional offline sales model to the e-commerce platform Changes in new sales models such as live streaming, delivery of goods, and social marketing. In 2021, with the acceleration of the pace of life, the popularity of online e-commerce, and the implementation of government encouragement policies, more and more consumers will be used to buying fresh non-staple food online. As consumers pay more attention to brand and price choices when buying eggs online, more and more breeding companies are adapting to changes in the situation, focusing on corporate branding, and striving for more opportunities to participate in online sales.
  4.4 Consumers pay attention to food safety and develop healthy breeding
   With the improvement of residents’ income and living standards, consumers have higher and higher expectations and requirements for the safety and nutrition of livestock products. Foods with high safety and good quality on the market will be favored by more consumers. Favor, people’s demand for eggs has also increased from meeting the demand for quantity to meeting the demand for quality. This trend requires egg producers to develop in the direction of healthy breeding, pay attention to the biological safety prevention and control of layer breeding and the surrounding ecological environment protection, so it is necessary to tighten the string of food safety to ensure the safety of edible eggs and protect the health of consumers . Reasonable industrial planning and layout, scientific field planning and standardized construction, standardized quarantine measures and implementation, inspection and control of inputs, harmless treatment and recycling of sick and dead livestock and poultry, and manure are all related to eggs. Important measures for chicken breeding biosafety and surrounding environmental protection are also important directions for the healthy development of the layer industry in the future.
  5 Suggestions for the development of the layer industry in 2021
  5.1 Prepare a response plan for emergencies such as the new crown pneumonia epidemic
  Laying hen workers should sum up their experience and enlightenment in the face of emergencies that have occurred; in the face of emergencies that may occur in the future, they should prepare a response plan. One is to do a good job in scientific site selection planning. The site should select suitable cultivating areas, non-basic farmland and other places, consider the needs of biosafety such as epidemic prevention, and take into account the convenience of transportation to prevent the”in and out” dilemma in emergencies. The second is to adjust the appropriate scale. According to the surrounding environment, production technology, biological safety, economic strength, management level and other factors, the appropriate scale of supporting aquaculture should be adjusted. It is not necessary to blindly seek large, pursue quickness, and ignore uncontrollable emergencies in the future. The third is to jointly build a risk-sharing organization. Joint insurance, futures, finance and other entities to form multi-party cooperative organizations that share benefits and risks, and establish a joint insurance mechanism to reduce breeding risks caused by emergencies.
  5.2 Strengthen early warning and control, and guide employees to organize production rationally
   In response to frequent egg price fluctuations and blind adjustments in production, the animal husbandry department should give full play to the production early warning and forecast system. First, we must pay attention to the collection of basic data such as production and price, and organize the reporting of data and information in a timely manner to avoid under-reporting, false reporting, under-reporting, and false reporting. Second, it is necessary to quickly carry out data collation and analysis, accurately study and judge market changes, production and consumption changes in a certain stage or period, and grasp the balance of supply and demand. Third, we must release early warning information in a timely manner, expand the publicity audience, let the majority of practitioners understand the industry dynamics in a timely manner, rationally organize production, transportation, warehousing, sales and other work to provide guarantee for the stable development of the layer industry.
  5.3 Promote high-efficiency and safe breeding technology to improve layer breeding level
   One is to promote the scale and standardization of layer breeding. Change the development model of”small-scale and large-scale” and increase the scale of layer breeding. Make full use of the role of the standardization demonstration field, take advantage of the promotion and application of new technologies and new equipment, and accelerate the standardization process. The second is to encourage the upgrading of layer breeding facilities and equipment. Encourage university research institutes and enterprises to carry out research on the intelligence of layer breeding equipment, and promote the full integration of the intelligence of facilities and equipment with Internet of Things technology. Encourage and support layer farms (households) to adopt intelligent facilities and equipment, and strengthen the automatic intelligent control management and real-time recording of inputs. Realize the intelligent management and early warning of egg product safety, environmental and ecological safety, and breeding biological safety. The third is to establish a comprehensive disease prevention and control system. Guide breeding farms (households) to strengthen breeding management, promote non-resistant breeding, and establish the concept that prevention is better than cure. Organize universities and research institutes to accelerate the progress of major vaccine research and development, improve vaccine research and development efficiency, and ensure the stable development of the layer industry.
  5.4 Explore mature and effective countermeasures
   At this stage, the industry’s “consensus” should be gathered to promote and guide the breeding industry to return to the essence of breeding. The first is to explore and reserve related technologies for”reducing and replacing resistance” to prepare for a comprehensive”feed ban”; use antibiotics rationally and scientifically in accordance with laws and regulations to reduce the harm caused by antibiotic abuse. Second, through anti-resistance and anti-resistance propaganda, to alleviate the fear of anti-resistance of the breeding subjects, promote veterinary prescription drugs, and reduce the overall use of drugs in small steps. The establishment of”do not expect to simply rely on non-antibiotic substitutes to solve the era of anti-feeding The basic bottom-line concept of “disease problems that are not eradicated”; strengthen the management of terminal animal product residues, and try to ease unnecessary concerns about “animal products containing resistance” in the consumption link. The third is to increase investment in research and development of substitute products, and actively research and develop substitute products. Initiate the research, development, promotion and application of major technologies for joint research of anti-anti-products, increase publicity in a timely manner, promote the transformation of results, and help enterprises consciously prohibit anti-anti-anti-anti-anti-restrictions.
