It is divided into three aspects: daily prevention and control measures, high-risk seasonal control measures, and disease control on farms.
First, the specific measures for daily prevention and control measures include all-in, all-out, pig control, environmental hygiene, daily disinfection, immunization, and admission control.
(1) All-in/all-out measures: refers to pig farms (fields of unsold sows) that only raise one batch of live pigs. When pigs are entered and slaughtered, they should try to do it at the same time. After the live pigs are all slaughtered, relevant sites and articles are implemented. Final disinfection: Thoroughly clean the farm and strictly use caustic soda and quicklime to disinfect. The utensils are soaked or sprayed with disinfectant solution. The closed housings can be fumigated and sterilized. The pig farms can be re-tested after 14 days of disinfection. Large quantities of pigs are best left empty for 1-2 months.
(b) Control measures for pigs in pigs. The following three points should be taken into account when pigs are introduced into pig farms:
1. Do not introduce live pigs from the affected area. Be aware of the national epidemic situation in a timely manner and master the epidemic situation in the pig farm.
2. When introducing pigs, they must go through the quarantine of the local veterinary department and do not introduce sick pigs.
3, to prevent the pig's stress response during transportation, the method is:
(1) Pay attention to keep warm, can be transported at high temperatures at noon, and prevent thieves from invading during transportation.
(2) Before and during the transportation, give enough clean drinking water and add electrolytic multidimensional and vitamin C powder, etc. Do not overfeed the feed.
(3) Actions should be light, slow and reduce irritation when driving pigs.
(III) Environmental Hygiene Measures. To keep pig farm clean and tidy, the bar is hygienically dry. The specific measures are as follows:
1. Sweep the farm every day to remove weeds and dirt in time to prevent the damage of rats, snakes and mosquitoes.
2. Clean the laps twice a day, morning and evening, to prevent contamination of excreta and urine, and eliminate water in the circle in a timely manner to keep it dry within the circle.
3, feces, dirt to be selected in the farm under the tuyere accumulation of fermentation or biogas digester reuse.
4. Under the condition of ensuring comfortable temperature (15-25 degrees), the ventilation of the pig house shall be strengthened, and the high ammonia concentration in the pig house shall be prevented, which will affect pig growth and disease control.
(D) Daily disinfection measures. Pig farms should establish a regular disinfection system, pay attention to the following four points:
1, the winter and spring seasons should adhere to disinfection once a week.
2, after disinfection 2-3 times to replace a disinfectant, dressing every 15-20 days in the winter season.
3. There should be a special disinfection pool and disinfection room at the entrance of the farm, and the personnel and vehicles entering and leaving the farm should be disinfected.
4, a variety of disinfection methods and precautions:
(1) UV lamp disinfection requires a very close distance (not more than 0.5 meters, no more than 2.5 meters after the destruction). UV penetration is weak, the back of the glass, clothing, hair inside the pathogen damage is not strong.
(2) spray disinfection requires no more than 3 square meters per liter of water spray, to ensure that the ground spray wet; with pig disinfection should choose odorless, and a small irritant disinfectant for pigs, such as iodine preparations.
(3) When the empty house is sterilized, it must be cleaned first, thoroughly washed with a high-pressure water gun and then disinfected with a disinfectant, and dried more than one week after disinfection.
(4) During fumigation, attention should be paid to the confinement, temperature, and humidity of the pig house. After disinfection, the window should be ventilated for a week. The method is: 7 to 21 grams of potassium permanganate per cubic meter is added to 14 to 42 milliliters of formalin. Fumigation disinfection. Fumigation, the general room temperature should not be less than 15 °C, relative humidity should be 60% -80%, can be added to the container before adding potassium permanganate formalin, closed doors and windows more than 7 hours Can achieve the purpose of disinfection, and then open the doors and windows for ventilation, eliminate residual odor.
(5) During flame disinfection, ensure that the flamethrower functions for a certain period of time.
(5) Immunization measures. The immunization of pigs should be done in a timely manner according to the procedure:
1, according to the epidemic of the local epidemic situation and the prevalence of pig farms to develop a reasonable immunization program. The pig broom, highly pathogenic pig blue ear disease, foot and mouth disease, streptococcus, infectious gastroenteritis and epidemic diarrhea, etc. For the immunization program; Haemophilus parasuis, gasping disease, infectious pleuropneumonia, edema disease, piglet vice injury as a selective immunization project.
2, to monitor the immune status of the pigs after the antibody level, according to the level of herds of antibodies raised the level of immune-related vaccine in a timely manner.
3, attention when pigs are immunized:
(1) 2 days before and after the injection of vaccine, given electrolytic multivitamin and vitamin C powder to reduce the stress response.
(2) The pig should be in a healthy state when immunized.
(3) Within 2-3 days before and after the vaccination, the pigs were given antibacterial and antiviral drugs, and no other vaccine was given within 4-7 days.
(4) The vaccine should be used as soon as it is opened, and the oil seedlings should be injected back to normal temperature after injection to reduce the pig's stress response.
(6) Admission control measures.
1. Minimize the number of outsiders and vehicles entering the site. All personnel entering and exiting areas must be strictly sterilized.
2. The following measures shall be taken for the outsourcing of live pigs:
(1) To isolate and observe for 14 days, the pigs can be reared in groups after being healthy.
(2) Pigs are quarantined for one week and the pigs are healthy before starting to make the vaccine.
(3) Freshly transferred live pigs should not be fed within two hours and should not drink water within one hour. Let the pig rest for one hour and then supply drinking water with a small amount of multiple methods, then drink for 30 minutes to prevent the pigs from drinking too much. Clean drinking water, plus electrolytic multi-dimensional and vitamin C powder. Two hours later, a small amount of gradually feed the pig, to reach the normal amount of feed after 1 day, to prevent overfeeding, the amount of oxytetracycline or Amo added in the feed Xilin and other preventive drugs.
(4) Set up the pigs to set up excrement and urine by means of sweeping the pen before the feed in the morning, and drive the pigs to the designated place in the pen circle to excrete the urine, so that the pigs can develop fixed-point eating and the habit of defecate urine.
Second, the high-risk season prevention and control measures refer to the prevention and control measures that should be taken in the pig farms during the epidemic. It includes emergency immunization, preventive drug use, high-risk season disinfection, and pig farm closure management.
(1) Emergency immunization. When the high-risk season approaches, regular monitoring of the pig's antibody level in the field, according to the level of antibodies in time to strengthen the immunization, to ensure that the pig has sufficient resistance.
(2) Preventive drug use measures. During the epidemic season, pigs should be given preventive medications to the rearing pigs. Attention should be paid to the following five points in the process of drug administration:
1, using intermittent dosing method. That is, after 3-5 days of drug administration, stop drug for a week, and then 3-5 days after drug administration, and then stop drug for a week.
2, antibacterial and antiviral drugs used at the same time. Such as terracotta powder and astragalus polysaccharide mixed feeding.
3, preventive medication should pay attention to the dose, usually half the therapeutic dose.
4, antibacterial drugs 1-2 courses change once, do not long-term feeding a drug.
5, to give room for therapeutic drugs. That is, to prevent the application of drugs to keep 2-4 kinds of drugs do not use, to prepare for treatment.
(C) high-risk season disinfection. The high-risk season should pay attention to the following three points:
1, to adhere to disinfection once every 1-2 days, replace a disinfectant every week.
2, to choose a strong disinfectant against the epidemic disease resistance. Bacteria and viruses, the ability to survive in the external environment is poor, as long as the disinfection measures are appropriate, commonly used disinfectants have a very good effect.
3. It is best to use a disinfectant with a small irritating odor when disinfecting pigs.
(D) Closed farm management. In the high season of epidemic disease, the pig farm should implement closed management.
1. Outside personnel and vehicles are forbidden to enter the farm, and personnel and pigs in the field cannot only enter the farm.
2. Send special personnel to purchase items every day, and purchasers are not allowed to enter the farm.
3. It is forbidden to purchase pork and its products from the outside world.
3. Control measures for diseased farms Once the farm is affected, comprehensive control measures such as isolation, disinfection, therapeutic use, secondary infection control, and symptomatic treatment shall be taken. The specific measures are as follows:
1. Isolation of sick pigs. Isolation occurs once, and healthy pigs and sick pigs need to be reared and managed by different people.
2, farm disinfection. Adhere to a day of disinfection, a week for a disinfectant, and to ensure the concentration of disinfectants.
3, drinking water administration. Drinking water to add electrolytic multidimensional, vitamin C powder and other drugs to improve immunity for the whole group to drink, the amount can be added 2-3 times as appropriate.
4. Mix the ingredients and feed them. Add antibacterial drugs and antiviral drugs to the feed for the whole group, and add aspirin, baking soda and other drugs according to the onset and medication status of the pigs. Note the following points at the same time:
(1) The use of antibacterial drugs should be replaced in 1-2 sessions.
(2) According to the feed intake of the pigs, adjust the concentration of administration to ensure that the pigs with reduced appetite feed enough doses.
(3) Diffusion method should be used for drug mix, and it is necessary to ensure that the mix is ​​even. The method is to mix the drug into a small amount of feed, and then stir the feed into a sufficient amount of feed.
(4) It is recommended to use a pulsed drug delivery method. The method is to use a conventional dose of 2 times the drug for 3-5 days, and then halve for 3-5 days. This method is 10-15 days longer than conventional drug use. The treatment effect is better, but it should be noted: the safety range and dose of some drugs. For example, the first dose of sulfa drugs should be doubled, and continuous use for no more than one week. The use of net overdose can cause obvious gastrointestinal reactions. Excessive use of fluorobenzol over long-term use may cause gastric ulcers.
5, injection administration. For pigs with decreased appetite or loss of appetite, the administration of injection, the principle of administration and precautions with the mixed feed. In addition, special attention, if the pig can drink or mix materials, try not to use injection method , because the injection method will cause a strong stimulation to the pig, not conducive to the rehabilitation of the disease.
6, Harmless treatment. Dead pigs should be buried in time and be strictly sterilized. Pigs and utensils must be strictly disinfected. The farm shall strictly implement the "four inaccurate and one treatment" measures. That is, no slaughter, no food, No sale, no transshipment, no harm to dead pigs.
First, the specific measures for daily prevention and control measures include all-in, all-out, pig control, environmental hygiene, daily disinfection, immunization, and admission control.
