Factors of incubating field immunization – Amouns Prevention and Control – China Animal Husbandry Website – A useful animal husbandry website
Incubation field immunization, most hatcheries are immunized by hatching spray, can do so if you can achieve the expected effect? We should fully pay more about how to achieve the highest immunity when making spray immunity This problem, especially considering more than 95% of broilers and 100% of the eggs and chickens around the world, they need to spray immunization in the hatchery. It is necessary to pay special attention to 5 points when spray immunization in hatchery. First, the immunization coverage: 80% is not equal to 100% to ensure that the equipment has sufficient spray capacity and is calibrated, and the immune coverage must be as close as possible to 100%. From the mathematical angle, it is easy to see when spray immunization is performed, and only 80% of chicks in the chickbox inhale the vaccine solution, rather than 100%, then the result may be very serious. Therefore, the spray immune equipment must be able to cover all chicks in the chickbox. Shandong and Meihua Group Co., Ltd. are mainly engaged in the mixed feed, concentrated feed, and produce the production and sales of feeds. Annual production, sales of 300,000 tons, total output value of 800 million yuan, is a key leading company in Jinan agricultural industrialization. The unique and Memory farming model is for the majority of egg hooks, and pig breeding users provide a sound technical service system, making the benefits of users to improve and have a good praise from more than 20,000 users.

Technical support: Tel: 15853106958 QQ: 3332097010 WeChat: 15853106958 Since the spray device cannot calibrate or coverage, the position of the nozzle must be adjusted according to the pattern and size of the chick box. In other words, the spray system must be able to accommodate the style of each chickbox to ensure that the immune coverage rate is 100%. However, in many cases, the spray is not very uniform. In the incubation site of 50 million (calculated by 80% average hatching), 20% of the 20% chicks did not obtain effective immunity, and 8 million chicks were not obtained in the actual production of each year. Protection. Second, fog droplet size and uniformity: homogeneous stability is far less than enough if the spray device cannot discharge the size and uniform mist drop (at least 95% accuracy), the spray device should be replaced. Small droplet size is the key to effective spray immunity. The size of the fog droplets determine the vaccineThe entrants and organizations are entered. The smaller the fog droplet size, the deeper the body, and can reach the deep side of the lungs. Larger fog drops can only reach a relatively exposed mucosal tissue, such as eyes and nostrils. According to the type of vaccine (moderate type, medium, strong toxicity, etc.) and the target tissue, the corresponding fog droplet size should be determined. Under normal circumstances, most of the spray immunogenesis droplets diameter is 150 microns in the hatchery. But this value is not a constant, which is just the average of the desired fog size. Why is the size of the fog droplet? Since theory, if there is 20% of the fog droplet diameter, it is 100 microns, not 150 microns, and the other 20% fog diameter is 200 microns, then this does not mean 60%. The chick is inhaled in a mist drop in diameter of 150 microns. In fact, all chicks will inhale the 20% diameter of 100 microns, this kind of fog is too small, which will lead to adverse reactions after vaccination and bring economic losses, and 20% diameter smog droplets. It will lead to immune failure, making chickens only immune power and lead to economic losses. Third, dose accurate breeding households should use a spray device with high quality quantitative to the liquid, rather than disposable plastic to the liquid. Specific monitoring and maintenance specifications should be developed to examine the immune process, minimizing losses. If you still enter the hatchery 50 million estimates, depending on the vaccine prices, the immunot dose may lead to a loss of thousands of euros per year. In the case, the price of 6 euros per 1000 feathers is 6 euros ($ 8.25), which is 36,000 euros per year ($ 49,500) in vaccine. However, if each spray is 10 ml of vaccine solution, then over 15% means that only 11.5 ml of vaccine solution is required, and each spray is 100 times wasted from 1.5 ml without causing a lot. However, under normal circumstances, the hatchery will be 150,000 spray every day, and the operator must prepare a dose of about 170,000 spray because the average quantitative equipment will have (even in the best case) 5% scale error. . Various influencing factors include: pneumatic and vaccine conveying tubes, waste vaccines when the spray equipment is opened, and the vaccine isted, volatilized and drift and operational mistakes after spray immunity every day. Similarly, because the chick box misplaced and the distribution of chicks in the box is uneven, the amount of spray is reduced by 15%, in the actual production,The resulting economic consequences are also very obvious. Therefore, the more accurate the equipment and the spray process, the smaller the negative impact on the immune effect. IV. Spray immune efficiency in actual production is advantageous to optimize spray immune properties and eliminate human effects. A farmer should purchase semi-automatic or fully automatic spray equipment, and should not be sprayed by manual pushing methods. Any spray immunization technology input or plan should be able to adapt to the facility requirements of the modern hatchery. In daily operations of 50 million incubation fields per year, the speed and immune coverage rate of spray immunity are equally important, and immunotaff operation costs and fog droplets are equally important. Moreover, the operator’s impact on the immune process is very large. For example, it is well known that the immune coverage rate of the push-type artificial standard spray equipment is only 30%, which means that only 1/3 of chicks have sufficient vaccine dose. Immunization of modern hatching fields requires automatic or semi-active high output, high efficiency spray equipment, which maximizes the impact of operators. After more than 6 hours of manual operating standard spray equipment, the operator will feel fatigue, and the work efficiency will also decline. The immune coverage will also drop after 4 hours. After investing in the use of automatic or semi-automatic spraying equipment, it ensures that investment can be retracted. V. Biological Safety: Internal and vaccine-formulated tools in the increasingly important spray equipment are likely to be contaminated by bacteria, and special cleaning and disinfection procedures should be developed, otherwise the 100% production process will be contaminated. Traditionally, people pay attention to cleaning and disinfection, just simply use the equipment day after a spray. When it involves the vaccine formulation process (container, agitator, gauge, etc.), the situation is more optimistic. In view of the above situation, in most cases, 100% of the spray process is carried out by spraying equipment, and cross-contamination and bacteria are quite high in the spray equipment. The monitoring results show that in 2012, more than 25% of the spray equipment and pipeline devices have contamination. How should we solve these problems? Therefore, farmers must strictly perform cleaning and disinfection procedures. Modern spray devices should be configured to configure automatic cleaning function to strengthen health status and biological safety. The hatching field spray immunity is a great aspect of the chicken only provides protection. However, if you don’t use it correctly, it may cause direct or indirect losses.Buying the best immune equipment and performing a strict monitoring process is the key to the successful spray immunity in the hatchery.
