Establishment

1. Introduction to the preparation process

(1) After the project was approved, Huawei Group took the lead in organizing and setting up a standard drafting group. The members of the group include Xuancheng animal disease prevention and control center Shuanghong poultry professional cooperative in Xuancheng City, Anhui Province Anhui Agricultural University, animal husbandry and veterinary administration of Xuanzhou District, etc. relevant technical personnel were selected from each unit to participate in the drafting of the standard, and the schedule and work division of the drafting were clarified.

(2) In order to optimize the breeding density, light, temperature, humidity and other parameters, we established a technical experimental base for cage broiler in Huawei Group, Shun'an Food Co., Ltd., and Muzi poultry professional cooperative.

(3) Extensive investigation, collection of standards related information, comparison of technical differences;

(4) Determine the overall framework of the standard, form the first draft of the standard, and widely solicit opinions;

(5) According to the solicitation of opinions, further improve the content of the standard, and form a standard draft for examination and approval, and apply for standard review.

2. The necessity and significance of establishing standards

At present, the scale breeding of broilers in our province mostly adopts the mode of ground level breeding or net frame breeding. Compared with the three-dimensional cage culture mode, it occupies more land, has lower breeding efficiency and higher veterinary drug residues. Therefore, it is of great significance to formulate the technical regulations for the management of commercial broilers and promote the three-dimensional cage breeding mode of commercial broilers, which is of great significance to save the land for broiler breeding, improve the efficiency of broiler breeding, reduce environmental pollution, improve the quality of broiler products, and promote the transformation and upgrading of broiler industry.

As a new type of broiler breeding mode, three-dimensional cage culture of commercial broilers has the characteristics of high density, high automation, fine feeding management and so on( one )Save land for farming. It has the advantages of high feeding density, less land occupation, saving land cost input and high yield per unit area. Chicken farm cage equipment three Layer three-dimensional structure, aquaculture per unit area 30-45 only / M2, at least if it is a flat feeding mode three For such a large chicken house, the cage mode saves equivalent to two The construction land of the same chicken house greatly reduces the land cost.   two )Low feed to meat ratio and high feed conversion rate. In the process of cage breeding, the maximum fine management can be achieved. The automatic feeding and water supply system can effectively reduce the waste of water and materials. The fine environmental control ensures the chicken to grow in a comfortable and healthy environment, which can greatly improve the feed conversion utilization rate. three )The survival rate is high. The chickens are separated from each other to reduce the transmission speed of infectious diseases and avoid fighting and pecking. four )The cost of heat preservation fuel is low. Because of its high feeding density, chickens have high heat production, which can be well utilized in winter, saving heating costs and reducing fuel costs.   five )Improve the quality of broiler products. The incidence of chicken flocks is low, and the cost of medicine and other inputs is reduced. Drug residues can be strictly controlled to provide food safety guarantee from the source. Chickens do not directly contact with feces by using conveyor belt, and the excrement is cleared once a day by the conveyor belt. There is no old manure in the chicken house, which can ensure the fresh air in the chicken house, reduce the production of ammonia, and reduce the oxygen consumption of feces in the chicken house, so that chickens have coccidiosis and large intestine The probability of bacteria and foot pad burns was almost zero. six )Automatic breeding equipment is used to save labor cost.

3. The principle and basis of formulating standards, and the relationship with current laws, regulations and standards.

This standard is formulated in accordance with the principle of "facing the market, serving the industry, independent formulation, timely introduction, timely revision and continuous improvement", and in line with the principles of advancement, scientificity, rationality and operability, and in accordance with the GB / T 1.1-2009.

4. Description of main clauses, description of main technical indexes, parameters and test verification (detailed description)

This standard specifies that The technical requirements such as the terms and definitions of commercial broiler cages, site selection and layout of chicken farms, design and supporting facilities of caged chicken houses and cages, feeding management, health management, epidemic prevention and control, etc

This standard mainly describes the following aspects: (1) Site selection requirements of chicken farms; (2) layout of chicken farms; (3) design and supporting facilities of chicken houses and cages; (4) feeding management; (5) biosafety and health management; (6) epidemic prevention and control.

5. If patents are involved in the standard, there should be a clear description of intellectual property rights

This standard does not involve patent issues.

6. If international standards or foreign advanced standards are adopted, the degree of standards adopted and the comparison of similar standards at home and abroad shall be explained

In recent years, cage breeding of broiler has gradually become popular in China. Hebei, Shandong and other developed provinces have been promoted earlier. Shaanxi, Guangdong and Fujian are also actively promoting and applying in recent years, and have achieved certain results. Some provinces have also formulated cage standards, which are different from those of our province due to different regional environment.

7. Handling process and basis of major differences

None.

8. Requirements and suggestions for implementing the standard (including organizational measures, technical measures, transitional measures, implementation date, etc.)

It is suggested to be the recommended local standard of Anhui Province.

(1) The animal husbandry and veterinary departments are responsible for the publicity, implementation and guidance of the standards, and organize technical personnel to carry out training and on-site guidance.

(2) Combined with the relevant project policies of poultry industry transformation and upgrading, enterprises are encouraged to gradually transition from flat breeding mode to cage mode.

three )Continue to carry out technical research and further improve the standard content.

9. Suggestions on Abolishing the current relevant standards

None.

10. Other matters to be explained

None.
