The current market prospects of mutton are very good, and the price of mutton has always been high. Therefore, many farmers want to expand the scale of breeding, but this is not an easy task. If they encounter infectious diseases, they will cause huge economic losses to the farmers. Not conducive to the development of China's sheep industry. Therefore, it is necessary to strengthen the epidemic prevention of sheep disease and timely vaccination. Let's take a look at the main points of sheep disease prevention and the use of common vaccines.
1 sheep disease prevention points
1.1 Establish a sound anti-epidemic system
The health of the sheep is related to the vital interests of the farmers, so the epidemic prevention of sheep disease should be strengthened. China has always attached importance to improving farming technology. At this stage, it has also achieved good research results in sheep disease prevention and epidemic prevention technology. With the progress of the times and the development of science and technology, the epidemic prevention work needs to be innovated, and a sound epidemic prevention system should be established through scientific and rational methods. Therefore, relevant departments should strengthen supervision and management work, and clarify the standards for sheep epidemic prevention, so as to avoid a large number of sheep deaths caused by improper epidemic prevention work. Once the dead sheep enters the market, the impact will be very bad and seriously endanger food safety. Relevant departments and farmers should enhance the awareness of sheep disease prevention, such as strengthening the training of relevant personnel, establishing a scientific disinfection system, and regularly disinfecting the sheep house.
1.2 Establish a scientific immunization program
In order to improve the immunity of the sheep and reduce the probability of infection of the sheep, the sheep need to be vaccinated during the breeding process. Immunization is very important. It is about whether sheep can grow healthily, so it is necessary to establish a scientific immunization program. When cultivating sheep, the farmers must make vaccination arrangements based on the actual conditions of the sheep's growth, that is, when the sheep grows to a certain stage, the vaccination plan for this stage is implemented. It is worth noting that if the sheep is in poor health or is a young sheep with maternal antibodies, it is not vaccinated. Therefore, before vaccinating the sheep, the farmers must understand the specific conditions of each sheep, observe and record their physical state, and carry out scientific and reasonable vaccination according to the norms. When vaccinating, be sure to use qualified vaccines and injection equipment, and the staff who perform the vaccination need regular training. The livestock management department should strengthen supervision and technical guidance to prevent the occurrence of major diseases.
1.3 Comprehensive epidemic prevention is in prevention
Many livestock infectious diseases can be circumvented through preventive measures. However, in the actual breeding process, many farmers tend to consider the immediate interests more, and in the absence of the epidemic, the idea of ​​saving aquaculture costs is not carried out. When an outbreak occurs, it is often difficult to deal with, causing major losses, which is not conducive to the development of the aquaculture industry. Therefore, preventive work should be done in a timely manner.
First, control the farming of sheep. Mainly refers to the principle of “self-supporting and self-supportingâ€. If there is a need for introduction, the introduced sheep must be placed in the quarantine area for several days to ensure that the introduced sheep are abnormal and very healthy before they can be introduced. The sheep are placed in the sheep house for polyculture. Second, strengthen the management of sheep breeding. In the feeding management process, in order to ensure the normal and healthy growth of the sheep, it is necessary to select the appropriate feed according to the actual size and growth of the sheep, and to achieve regular and quantitative feeding. When feeding the feed, pay attention to check all the feed regularly. If the feed is found to be moldy or insects, the feed should not be fed to the sheep. In addition, the drinking water needs to be clean and temperature suitable. Third, to maintain a good sanitation environment in the breeding grounds, clean, ventilate and disinfect the sheep house regularly and irregularly to prevent the growth of bacteria and effectively prevent the occurrence and development of diseases.
1.4 Measures to be taken when an infectious disease occurs
Once an infectious disease is found in the flock during the breeding process, the diseased sheep must be immediately isolated, the ward should be isolated and blocked, and the condition should be reported to the animal husbandry and veterinary department step by step, diagnosed by the superior veterinary department, and processed in accordance with relevant regulations and standards.
2 common vaccines and methods of use
2.1 Non-toxic anthrax spores
Non-toxic anthrax spores are a common class of anthrax vaccines. More experienced farmers are familiar with this vaccine. It should be noted that in order to improve the injection efficiency, inoculation of this vaccine requires subcutaneous injection. The vaccine is administered at a dose of 0.5 mL, and after 2 weeks of injection, the corresponding antibodies are produced in the sheep. In order to ensure the immune effect, it is recommended to inject a non-toxic anthrax spore seedling once a year to improve the immune effect.
2.2 tetanus alum sedimentation of taxomycin
Tetanus aflatoxin is mainly used to control tetanus blight. The tetanus disease is extremely harmful to the flock. Once a sheep is sick, the sheep will die in a short time, causing serious economic losses. The sheep were given a tetanus injection of tetanus, mainly by subcutaneous injection, using a dose of 0.5 mL, and the sheep produced antibodies in vivo one month after the injection. In order to ensure the immune effect, it is recommended to inject once a year to improve the immune effect.
2.3 O-type foot-and-mouth disease inactivated vaccine
Among the flocks, foot-and-mouth disease is also a relatively common type of disease. The O-type foot-and-mouth disease inactivated vaccine injection method is different from the above two vaccines, and the intramuscular injection is performed at a dose of 2 mL, which is significantly higher than the dose of the above two vaccines. It should be noted that the lamb's immunity is weak, so the injected dose is reduced to 1 mL. The sheep will produce antibodies 15 days after the vaccination, but since the vaccine can only last for 4 months, it needs to be re-injected regularly.
2.4 sheep, goat pox attenuated freeze-dried seedlings
Inoculation of sheep and goat pox attenuated freeze-dried seedlings is mainly used to prevent diseases such as sheep rapid epidemics, intestinal toxemia and lamb dysentery. The inoculation of sheep and goat pox attenuated freeze-dried seedlings is to inject 1 mL subcutaneously or intramuscularly, and produce antibodies after 14 days of injection to enhance the immunity of the sheep.
2.5 sheep rapid epidemic-çŒç–½-intestinal toxemia triple vaccine
The vaccine is mainly used for the prevention of rapid disease, intestinal toxemia, sputum and lamb dysentery. When used, it is dissolved in dry powder seedling 20% ​​aluminum gelatin. Regardless of the age of the sheep, a 1 mL dose was administered subcutaneously or intramuscularly. Immunity was produced 14 days after injection, and the immunization period was 1 year. The wet seedlings should be shaken before application, and 5 mL should be injected under each sheep skin or intramuscularly for 6 months.
