Comprehensive management of pig farms, from the design of the site to the daily feeding and management and health care, must have a comprehensive set of management measures in order to ensure the normal operation of the farm and maximize the efficiency and economic efficiency of the farm.
Pig site selection and layout
The farms should be built in Xiangyang, lee, with good ventilation, good water quality, convenient drainage, convenient transportation, and sandy land. It is advisable to have supporting fish ponds, fruit trees, and arable land for the treatment of manure, to achieve comprehensive utilization, to achieve a virtuous circle, and to avoid environmental pollution.
The layout of the farm should arrange the breeding of core groups, breeding grounds, general breeding grounds and finishing pig houses in order of wind direction. That is, the breeding core group is in the upper hand, and then arranged from the life management area to the production supporting area (feed processing plant, feed warehouse, veterinary laboratory, disinfection dressing room, etc.) and then to the production area (pig house). The production area is arranged from the upwind to the downwind direction according to the mating hen house, branch house, nursery house, growth measuring house, bred house, and loading pig stand.
Take closed isolation feeding
Production areas shall set up fences and epidemic prevention ditch, and plant thorny plants outside the enclosure to form epidemic prevention forest belts, leaving only entrances for personnel, entrances for feeds and exits for bred pigs, so as to minimize direct contact with the outside world.
The personnel entrance and feed entrance between the life management area and the production area should be separated from the disinfection tank. A disinfection passage must be set up at the entrance of each pig house in the production area. The production personnel can enter the pig house after being re-sterilized.
Strengthen the hygienic work of the loading pigs. The loading pig station should normally be closed to prevent entry of outsiders and animals; the breeder does not contact the pig transporter when the pig is sold, and any pig cannot be returned to the original pig house once it is rushed to the pig station. After loading the pig, the pig station must be strictly installed. disinfection.
If it is a breeding farm, a breeding pig breeding room should be set up. The purchasing room and the production area must be kept at a certain distance, between the production area and the living area, separated by a partition wall (reserved sealing glass observation window) or a fence, outsiders You must change shoes and disinfect before entering the breeding pig room and select breeding pigs in the selection room.
Feed shall be transported from the feed truck outside the production area to the feed circulation warehouse. The vehicles in the production area will be transported to each pig house. It is forbidden to transport the feed directly into the production area. Any articles or tools (including vehicles) in the production area must not leave the production area except for special circumstances. Any items entering the production area must undergo strict disinfection. In particular, the feed bags should be fumigated before they can be loaded into the production area. It is best to use feed towers on conditional farms to avoid introduction of contaminated feed bags into the disease.
Immunization
The immunization work is one of the important methods for preventing diseases. The type of vaccine used in the farm should be determined based on the prevalence of the epidemic in the area, the nature of the vaccine, the climatic conditions, the health of the herd, and other factors. The sow should be considered comprehensively. Maternal antibodies, the age of the onset of the pig, and the specific conditions of the onset of the disease, were planned immunizations on a weekly or monthly basis, and standardized operations were performed. During the implementation process, it is necessary to periodically monitor and control the growth and decline of antibodies against various diseases. When the effect is not good, vaccines should be supplemented in time and the immunization procedures should be adjusted to ensure the effectiveness of the immunization.
Sanitizing
Disinfection is an important part of cutting off the epidemic diseases. The pig farm should formulate a disinfection system, which mainly includes the following items: First, the nurses of the breeding staff and delivery rooms should disinfect the arm when working and wear disposable rubber gloves to operate the piglets. The use of sterilized instruments should be used for the tail, teeth, castration, ear numbering, injection of iron, etc. Secondly, the epidemic prevention and treatment equipment should be disinfected once a day. The epidemic prevention and surgical instruments should be used separately, before and after each use. Disinfection; Third, the dead pigs should be disinfected after dissection, and the site should be cleaned and disinfected so as to reduce the incidence of disease.
In addition to suspicious cases sent to check the disease, each year in the pigs by a certain percentage of blood for inspection, monitoring of the disease, while doing the following work:
1. Regularly check drinking water and feed to ensure the quality and safety of drinking water and feed.
2. Timely elimination of sick pigs and pigs with no therapeutic value to prevent the spread of the disease.
3. Do a good job of cooling off the heat, keep warm and cold, clean and hygienic and keep the air in the pig house clean.
4. According to the pigs in different periods to provide full-priced feed to ensure the normal operation of the pig's immune system.
5. Breeding pigs and domestic pigs set up sports grounds to enhance sports and enhance body resistance.
6. The source of purification, do a good job of purification and rejuvenation, choose the best and bad.
7. Insist on self-cultivation and self-cultivation. When it is necessary to introduce pigs, they must be isolated for 30 days to 90 days before confirming that there are no epidemics and then transferring them to the breeding area for breeding.
8. Adopt the "all-in, all-out" method, the barnhouse is strictly disinfected, and vacant for a few days before being transferred to the new herd.
Epidemic emergency measures
If pigs develop infectious or suspected infectious diseases, they should be immediately quarantined, fully sterilized, and dealt with accordingly. Any pigs, vehicles, and other animals and articles that may be the route of transmission are strictly prohibited from being shipped out.
Blocked epidemic points, in the event of an outbreak, combined with the specific conditions of the epidemic to strengthen disinfection, and isolation or culling of sick pigs. According to the order of health groups, suspicious group vaccination. Dead pigs and wastes are treated as harmless. Disinfect sewage, eliminate rodents, and eliminate mosquitoes to prevent the spread of pathogens. Collect the material for inspection and diagnose the disease early. The last pig was cured or treated. After a period of time without new cases, the infected epidemic site was strictly sterilized, and it was vacant for one week before resuming production.
