Text/Agriculture and Animal Husbandry Frontier Zhu Jingqiang Intern Editor Yuan Heling
The pig raising in the "iron bucket" building now resounds throughout the country, and Yang Xiang has contributed a lot.
Yangxiang, known for its "low cost", focuses on self-raising pigs and serving pigs. In the era of non-epidemic disease, Yang Xiang has achieved a great improvement in the prevention and control of pig farms through the "iron barrel" building system. In the anti-resistance era, how does Yang Xiang respond to the risk of anti-resistance through a healthy pig raising system, and achieve cost reduction and efficiency increase without anti-resistance?
Healthy pig raising depends on the system. How does Yangxiang achieve low cost in the era of no resistance?
Dr. Yu Haifeng, Director of Technology and Service, Yangxiang Group, Henan and Hebei District
The sixth issue of No Anti-Bright Lights, Frontiers of Agriculture and Animal Husbandry Dialogue with Dr. Yu Haifeng, Technical and Service Director of Henan Hebei District of Yangxiang Group, to explore Yangxiang No Anti-res, share Dr. Yu's experience in technical support for large-scale pig farms, and improve the management level of pig farms. Unique insights into production performance.
1. Yangxiang, healthy pig raising depends on the system
Healthy pig raising depends on the system. A pig farm wants to raise pigs, especially in the era of no resistance. What are the specific aspects of this system?
Yu Haifeng: We explored and summarized the five elements of pig raising. The first is genetic inheritance, combining traditional quantitative genetics and modern molecular genetics to improve the reproductive performance of pigs; the second is precise nutrition, precise raw material testing, nutritional requirements, formula adjustment, production technology and feeding management; the third is biological safety and soundness System and system to strengthen disease prevention, monitoring, and treatment capabilities; the fourth is environmental control, which is practiced in automation and intelligence; the fifth is production management. According to the hardware conditions and large-scale conditions of the pig house, Yangxiang develops pig raising The process pig house model has undergone open, semi-open and closed models. Batch management is implemented under different models to achieve full-in and all-out, simultaneous estrus, simultaneous breeding, simultaneous delivery, data benchmarking and simplification of production processes.
In the face of the ban, what optimization has Yang Xiang made to pig feed? What are the key indicators?
Yu Haifeng: Raw material optimization: For bans, the choice of raw materials is currently the most concerned. Different companies have different focuses. Yangxiang focuses on the selection and combination of large raw materials, including raw material origin, evaluation of raw materials before purchase, control of raw material hygiene indicators, and control of raw material quality between different batches.
Nutrient optimization: We scientifically evaluate the combination of raw materials and are committed to solving the problem of excessive nutrients. Based on the low-protein diet, we consider the increase in nutrients related to intestinal health, and then adjust it according to different breeding environments. The focus of feed focuses from the optimization of education and protection feed, the optimization of lactating sows to the integrated mother-child nutrition, and the design changes from only focusing on the nutrition during lactation or late pregnancy, to the implementation of nutrition packages for the full reproductive cycle; thinking, from late pregnancy The "backgammon" mode of fetal attack to the "high-low-high" mode of high production performance sows can alleviate the problems of overnutrition and late reproductive performance obstacles. Focus on indicators: adjust the use of fiber and amino acids related to intestinal health in the absence of resistance.
There are various anti-anti-additive products on the market. Which anti-anti-additives does Yang Xiang use in pig food?
Yu Haifeng: We advocate the gradual use of alternative products, such as enzyme preparations, acidulants, essential oils, and microecological preparations, in the process of optimizing the use of bulk raw materials. From 2010 to 2018, Yangxiang evaluated and screened many products, and put them into use after comprehensive evaluation. Use probiotics in the designated stage to help balance the intestinal microecology; if the source of raw materials is wide, the use of enzyme preparations and acidifiers should be increased accordingly; high-grade pig feed is matched with the "luxury package", and all four products are added. Many adjustments will be made in the future without resistance, such as the conversion of trace elements from inorganic to organic; anti-stress vitamins should solve the stress of weaning, the stress of refeeding, and the stress of sows in the late pregnancy. At present, companies do not have the ability to use one or one or two products to solve problems. The use of anti-additive products requires a "luxury package" (combined use).
Yangxiang has been screening replacement products for many years. Can you tell us about the pits that can be avoided in the screening process?
Yu Haifeng: The indicators we evaluate are daily weight gain, material ratio and added cost, taking into account the rate of return. Diarrhea alone does not have the power to explain. A large amount of test data is the only way to identify whether it is effective and avoid jumping into the pit.
How do you share the processing technology of non-antibiotic feed?
Yu Haifeng: Feed mills must do a good job in biological safety prevention and control. Because it is a specialized pig feed factory, Yangxiang has unique advantages in terms of cleanliness compared with other compound factories. In addition, the feed factory has a first- and second-level decontamination and professional disinfection team, and a four-level non-non-reflective structure.
In terms of processing technology, I think the evaluation and selection of raw materials are the basis. In the production process, we implement multi-layer modulation and multi-layer holding, and the preparation and holding time is more than 150 seconds. At the end of 2018, Yangxiang realized the braising irrigation process to ensure that it can achieve 85℃, ten minutes maturation.
In addition, Yangxiang's factory cleanliness and sanitation control are very strict. In the past, customers had to go to the factory's mixer, feeding port, weighing room, and office to sample and test PED every month. After the epidemic, it has withstood the inspection of most cooperative enterprises. And many unannounced visits. We sacrifice a part of the profit to prevent non-compliance, so the factory has greater advantages in terms of cleanliness, biosafety level and production technology.
2. Benchmarking management and efficiency improvement projects
In addition to the optimization of feed, the breeding end should also make some changes in the environment, hardware, and feeding management to adapt to no resistance. What are the main changes? What experience does Yang Xiang have in this regard?
Yu Haifeng: The environment and hardware are mainly bio-safety transformation. For example, Yangxiang has always advocated "iron barrels for anti-fungal protection". All people, pigs, materials, and vehicles in the pig farm must be filtered. Doing structural design on the hardware, without working hard on structural design, it is difficult to change from the root cause.
In terms of personnel management, the pressure on employees under high epidemic conditions needs to be relieved, and Yang Xiang improved the sharing system for this. Let everyone give full play to their subjective initiative and implement the anti-failure system.
From the aspect of breeding management, we implement different production management methods according to the funds and management capabilities of different companies. For example, the northern region recommends large batch production and all-in all-out management models. After no resistance, the service will be adjusted in terms of weaning age, feeding package, and feeding mode, and it cannot be "one move to beat the world."
The large-scale pig farms are relatively complete in terms of hardware and equipment. If you want to further improve the production performance, what should you do? How to improve the energy efficiency project and benchmarking management?
Yu Haifeng: Enhance the efficiency of the project and benchmarking management are the characteristics of Yangxiang. Under the condition of complete hardware facilities, cultivating the biosafety awareness of all employees, understanding and implementing anti-non-non-safety measures are important prerequisites for raising pigs or for the current safe transition to resistance-free.
Benchmarking management: Benchmarking management refers to benchmarking with the industry and within the company to find its own strengths and weaknesses, and then establish projects.
Improve the efficiency of the project: the process of project approval requires a fixed person in charge, the implementation time of the project, the elements of the project, the milestone events at each stage of the project completion process, and the incentive measures after the project is completed. The establishment of a project is to implement the management of small projects in different stages, find the weaknesses and then establish the project, find different resources to solve the problem, solve the problems in one stage, and the production performance can be gradually improved. If every link in the pig raising process is done well , Then the entire pig raising process is done.
For small feed companies or small pig farms, they may not be prepared until now, and it will take some time to adjust slowly. For these feed and breeding companies, what problems may occur after they are resistant? For these problems, you Any suggestions?
Yu Haifeng: If the commercial feed enterprise customers are not high-quality or the breeding management is at a disadvantage, the future face of no resistance may be large-scale diarrhea in pigs. At present, everyone has excessively reduced the protein level of low-protein diets, and the growth rate is greatly affected. To solve these problems, you can start from three aspects. First, with the help of third-party platforms, many third-party companies now have technology platforms that can detect and control raw materials; second, cooperate with and communicate with large companies. Obtaining technical support can make up for the shortcomings; third, cleanliness, in the production process, try to make the sanitary indicators and cleanliness level well.
From the current point of view, if small companies have a fixed customer base, technical reserves, and sales capabilities, they can adjust in time according to the situation. Compared with large companies, they are more flexible and have certain advantages.
3. Small-scale pigs can also be raised in buildings
Many large-scale enterprises are now raising pigs in buildings. Small-scale pig farms and ordinary farmers can raise pigs in buildings? How can they do it?
Yu Haifeng: Everyone can build buildings and raise pigs. Building houses and raising pigs requires reliable design ideas, reliable design schemes and capital investment. Building houses and raising pigs requires a relatively large amount of funds, and requires higher management and production technicians. If you want to build a building to raise pigs, you should communicate more, understand and learn more, and consider environmental control, ventilation, feeding mode, pollutant discharge mode, pig material truck in and out mode, etc. to reduce cross-contamination. Risk, after having some knowledge of the building conditions, decide whether to enter the building for breeding.
Q: You just mentioned the increase in the dosage of enzyme preparations and acidulants, how much can it be increased?
Yu Haifeng: The amount of additives should be determined based on the source of dietary raw materials. When adding enzyme preparations, acidifiers and other additives, we will invite professional people to evaluate, combine the composition of the diet to conduct field trials, and finally draw up a plan.
Q: How to avoid diarrhea when entering pigs?
Yu Haifeng: We rarely have large-scale diarrhea in pigs. First, from the perspective of breeding management, the decontamination process can be optimized. The pig house is decontaminated and dried at 65 degrees for more than 10 hours before loading the pigs. , Improve the cleanliness of the pig house; second, let the upstream sow farm cool down the farrowing room before entering the pigs, and warm up the nursery room 2 to 3 days in advance to ensure that the temperature will not cause stress to the pigs; third, nutrition Diarrhea or stress diarrhea usually occurs 4 to 5 days after the pigs arrive on the farm. If the pigs have diarrhea just after they arrive, it may be related to the upstream source of pigs, and timely communication and adjustment should be made with the upstream sow farm.
Q: Can you talk about backfat management?
Yu Haifeng: The breeds of each pig farm are different, and the backfat standard of any company cannot be used to pull the back fat. The backfat data should be combined with the production performance of the sow, such as piglet birth weight, feed intake during lactation, and weaning After the fat loss, evaluate the backfat management of the sow at different stages and formulate parameters. Different people will have errors in the measurement of backfat, so we fix 1-2 people for back-label management, and the data obtained is meaningful and repeatable.
Q: Regarding the personnel management and scheduling of the pig farm, what suggestions does Yang Xiang have to share?
Yu Haifeng: First of all, the superiors and subordinates must share the joys and sorrows, and participate in and participate in the production process of the pig farm; secondly, there must be a better platform for scheduling, and there must be more room for improvement; and finally, we must according to each person's ability range and personality Carry out the division of labor, let everyone do what they like to do, perform their duties, and show their strengths.
Q: How do companies provide technical services to farmers to solve the problem of resistance?
Yu Haifeng: The biggest service at the moment is to help customers successfully prevent fraud and ensure the survival of pigs. We combine the company's own capabilities and personnel reserves to take corresponding anti-non-non-standard measures, and provide people with technical knowledge and bio-safety awareness to help customers check production technology weaknesses and prevent non-vulnerabilities. In most cases, customers need not only labor, but the assistance of people who understand production technology and biosafety technology.
Q: Can you share successful customer service cases?
Yu Haifeng: For example, when a customer introduces pigs, the first thing they think of is Yangxiang. We can provide sampling and inspection, assist in decontamination, contact transfer pig logistics vehicles, design processes, and road steps. Customers only need to pay the corresponding fees. Everyone in Yangxiang knows how to prevent faults, but also personally participates in the practice and reforms together with customers. Only when the company consists of such personnel can it serve better.
Q: How to prevent and control diarrhea in piglets 7~15 days after delivery?
Yu Haifeng: It may be related to the feeding and management of pregnant sows or the nutrition during lactation. The first aspect is to control the condition of sows, and to prevent and treat postpartum endometritis and mastitis in time; the second aspect is to control the feeding of sows; the third aspect is to keep the breeding environment dry. We should first distinguish whether it is a nutritional problem, a feeding management problem, or a disease problem, and then "prescribe the right medicine."
Q: How to ensure the sow's feed intake under the conditions of high temperature and humidity in summer?
Yu Haifeng: We must first improve the hardware conditions, otherwise the problem cannot be solved from the root cause. If the environmental conditions cannot be improved, the solution can be taken. First, you can stagger the feeding time, a little earlier in the morning and a little later in the evening to avoid the high temperature and high humidity period; second, ensure the sanitation of the trough, the cleanliness of drinking water and the amount of drinking water.
Q: As far as you know, what is the biggest difficulty in re-raising a pig farm?
Yu Haifeng: First, the boss is worried about capital, technology, and future policies, and lacks confidence in rehabilitation; second, the boss has no technical reserves or technical support, and cannot fundamentally solve the problem of non-non-prevention.
Q: The price of pigs has been rising recently, what do you think will happen to the price of pigs in the future?
Yu Haifeng: First, the price of pigs is related to the region; second, the price of pigs is related to the timing of selling pigs. At present, the key is still whether you can feed the pigs and whether you can bear the temper. If you can bear the temper and don't panic selling, I think the price of pigs should be more optimistic, at least in the short term.
Q: Will it be effective to add dietary fiber or microecological preparations to increase the sow's feed intake?
Yu Haifeng: Dietary fiber should be the most expensive feed material for sows, and domestic sources of fiber are limited. If there is a source of fiber and the quality is controllable, appropriately increasing the fiber will greatly improve the sow's feed intake and health.
If you can use appropriate probiotics at different stages of the sow, you can have a very good effect.
Q: You have always been on the front line, and now you are also fighting in Hebei District, Henan. Compared with other PhDs, you seem to be more difficult. Do you think this is very unbalanced?
Yu Haifeng: Everyone chooses differently, but now that they choose, even if they don’t like it, they should like it slowly. Together with colleagues who raise pigs on the front line, we help them solve problems through practical operations on the spot. Not only did they gain practical experience, but also reflected a pioneering spirit, and the subsequent command and work were more coordinated.
