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.
1. Site selection and layout of the farm The farm 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.
2. Closed and isolated production areas should establish 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 outlets for bred pigs 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.
Third, loading pigs should usually be closed to prevent outsiders and animals from entering. When the pigs are sold, the breeder does not come into contact with the pig transporter. Any pig can not be returned to the pig house once it is rushed to install it. After the pig is installed, the pig station is strictly sterilized. 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 trucks outside the production area to the feed circulation warehouse. The vehicles in the production area will then be transferred to each pig house. It is forbidden to feed 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.
V. Immunization Vaccination is one of the important methods for preventing diseases. The type of vaccine used in the field should be determined on the farm according to the prevalence of the disease in the area, the nature of the vaccine, the climatic conditions, the health of the herd and other factors. Taking into consideration the maternal antibody of the sow, the age of onset of the pig, and the specific conditions of the onset of the disease, the planned immunization was conducted 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.
