Abstract

The invention discloses a method for cleaning a pig farm to prevent diseases. Pig groups are divided into antibody negative subgroups and antibody positive subgroups according to immunity antibody detection; strengthen immunization is conducted on the antibody negative subgroups, immunity antibodies are detected again after immunization, and antibody positive pigs are brought into the antibody positive subgroups; fluid of umbilical cords of piglets is collected as detection samples when sows in the antibody positive subgroups give birth to the piglets, hog cholera virus and porcine pseudorabies virus are synchronously detected through a PCR method, and the pigs negative for both hog cholera virus and porcine pseudorabies virus are kept; regular casual inspection and comprehensive detection are conducted on the kept pigs, the pigs positive for both hog cholera virus and porcine pseudorabies virus or positive for one of hog cholera virus and porcine pseudorabies virus are weeded out, and then hog cholera virus and porcine pseudorabies virus are synchronously cleaned away. By synchronously cleaning away hog cholera virus and porcine pseudorabies virus, the method is high in efficiency, small in stress and easy and convenient to operate.

Porcine pseudorabies is one of the primary diseases of various infectious diseases in swine herds. Pigs infected with porcine pseudorabies or swine fever in large-scale pig farms directly or indirectly cause diarrhea in piglets in the farrowing room, high defect rate in nursery pigs, and respiratory diseases in medium and large pigs, resulting in high mortality and high morbidity. cause huge economic losses.

[0003] At present, in large-scale pig farms, separate purification methods are adopted for swine fever and porcine pseudorabies. For the purification of swine fever, the...
