Epidemic prevention method suitable for rural free-range pigs

Abstract

The invention provides an epidemic prevention method suitable for rural free-range pigs. The method comprises the following step of establishing the immune antibody decrease and increase rule of the hog cholera of the rural free-range pigs, a foot-and-mouth disease and a highly pathogenic pig blue ear disease, and an immune procedure. A ''CSF, FMD and HPPRRS three-vaccine-synchronization two-pointcommon immune technology'' is adopted for the rural free-range pigs, which accords with a rural traffic geographical condition and a current rural pig breeding situation, a current pig epidemic prevention situation is changed and rural free-range pig immune pattern conversion is accelerated. A set of new CSF, FMD and HPPRRS prevention and control mode suitable for a basic level is provided so asto reduce the labor intensity of basic-level epidemic prevention personnel, improve work efficiency and increase immune quality. Through implementing programmed immunity, village-level epidemic prevention officers have a large time control right so that animal epidemic prevention work can be organically combined with agricultural production, and the operability of basic-level animal epidemic prevention work can be improved, and an epidemic prevention effect is comprehensively improved.

Description

technical field [0001] The invention relates to the technical field of free-range pig breeding, in particular to an epidemic prevention method suitable for free-range pig breeding in rural areas. Background technique [0002] Traditional rural free-range pigs are an important part of the current rural pig industry, supplying a lot of pork to local cities. Rural free-range pigs are also one of the main sources of farmers' economy, but the scale of rural pig breeding is extremely small, and it is based on Free-range farming is the mainstay, and the management is extremely extensive. In addition, farmers underestimate the economic losses caused by animal diseases. Most farmers have a weak awareness of animal disease prevention and do not pay enough attention. Unlike professional farms (households) that invest a lot of money to improve the housing environment, compared with large-scale farms, they are seriously behind in terms of epidemic prevention facilities and breeding techn...

[0002] Traditional rural free-range pigs are an important part of the current rural pig industry, supplying a lot of pork to local cities. Rural free-range pigs are also one of the main sources of farmers' economy, but the scale of rural pig breeding is extremely small, and it is based on Free-range farming is the mainstay, and the management is extremely extensive. In addition, farmers underestimate the economic losses caused by animal diseases. Most farmers have a weak awareness of animal disease prevention and do not pay enough attention. Unlike professional farms (households) that invest a lot of money to improve the housing environment, compared with large-scale farms, they are seriously behind in terms of epidemic prevention facilities and breeding technology, and their risk of epidemics also increases. The effect of prevention and control needs to be paid more attention to. Although large-scale farms have taken effective measures to control animal diseases, due to the existence of adjacent small-scale farms or free-range animals, large-scale farms continue to have potential threats of re-infection. For the prevention and control of major animal diseases in pigs, all localities have been implementing the "spring and autumn two prevention" epidemic prevention mode of centralized immunization in spring and autumn every year, and regular supplementary immunizations every month

[0003] The traditional "spring and autumn" epidemic prevention mode is no longer suitable for the current pig disease immunization requirements, and the immune effect is not ideal. (1) The traditional "spring and autumn two prevention" mode of epidemic prevention has complicated procedures, time constraints, and heavy tasks. Most of the rural breeding areas It is relatively remote, with rugged terrain, inconvenient transportation, and scattered pig farmers. Each epidemic prevention officer is responsible for the epidemic prevention work of more than 200 households in 2 to 3 natural villages. In the traditional epidemic prevention mode, each pig has to be immunized against 3 diseases at different time intervals, and the epidemic prevention personnel need to complete the immunization of highly pathogenic PRRS, swine fever, and foot-and-mouth disease within 40 days, which is difficult to meet the national requirements. ( 2) The centralized arrangement of epidemic prevention work conflicts with seasonal agricultural production. The time of "spring and autumn prevention" conflicts with the time of spring plowing and autumn harvest. The epidemic prevention personnel are all part-time farmers, and their main source of income is still farming. For them, the epidemic prevention work seems to be a little secondary, resulting in a passive situation in the epidemic prevention work. Farmers and epidemic prevention personnel are passively accepting services and carrying out epidemic prevention work at the request of their superiors. (3) Due to the traditional "spring and autumn two prevention" Because the interval between the end of spring defense and the start of autumn defense is as long as 150 days, during this period, it happens to be the slack season, the trading of live pigs is frequent, and the fluidity of pig herds is very high. There is a gap in epidemic prevention. (4) Because the farmers mainly use free-range farming and the management is extremely extensive, the sanitary conditions in the pigsty are extremely poor, making the pigs extremely vulnerable to bacteria during the growth process, resulting in a very high disease rate of pigs
