Changsha Partial PRRS Prevalence And Its Prevention And Control Technology Research

[purpose] In 2006, in a number of provinces and cities nationwide to highly pathogenic porcine reproductive and respiratory syndrome (PRRS), after the onset of fever, dyspnea was abdominal breathing, serious was sitting dog breathing; inflammation of the conjunctiva, most swine have traces of tears; ears, abdomen, buttock skin was purple red patches. The urine was yellow or dark brown; pig hindquarters weakness, walking and rocking. The disease duration ranged from 5 to 10 days, the incidence rate of piglets and fattening pigs was 100%, mortality rate of more than 50%. Sow is mainly manifested as abortion, stillbirth and infirm piglets, the abortion rate of up to 40%, many farmers because the disease suffered heavy losses, even more "disease" leads to poverty. In spite of this, the farmers still have no knowledge of the disease, did not do a good job in preventive measures, or because of inappropriate immune, prevention and control, resulting in loss of. This paper mainly through scientific data collection and scientific experiments, from the use of the vaccine and the immune order, the traditional Chinese medicine treatment and comprehensive prevention and control, and so on, to provide a scientific basis for the prevention and control of PRRS.[method] The author from 2009 to 2013, the Changsha City 328 middle and small scale farms visited the site survey and data collection, and one of the three pig pig serum sampling analysis, when the incidence of small scale farms of PRRS; and for the injection of PRRS vaccine and CSF vaccine immune order the different time interval, the difference of experimental groups, to be vaccinated one month after the detection of the antibody level of value; at the same time to verify the experimental conclusion; for the initial onset of the disease by pigs, pigs were divided into three groups, respectively by different methods of traditional Chinese medicine treatment, based on the detection of food intake, mental health etc. the observation and temperature, summed up the treatment of Chinese medicine.[results] 1. In surveys of small scale pig farm, and take measure of immunity farms accounted for only 78.95%, no implementation of immunization accounted for to the 21.05%. Once had the disease of pig farms accounted for 57.62%, no illness or uncertain accounted for 32.38%. On some farms for sampling, sampling rate of 100% pig infection.2.The first CSF immune immune PRRS and CSF interval of one week, the highest pass rate of only 75%, while the PRRS the highest pass rate of only 80%, but the first immunization with PRRS vaccine and CSF vaccine, and the interval for a week, CSF pass rate in more than 85%, and the qualification rate of PRRS is 100%, both of which proved immune effect can be guaranteed, and the interval of more than two weeks, the qualification rate reached 100%, and through the verification of the results of 3 pig farms, that the conclusion is consistent with the actual production, to meet production needs; 3. the traditional Chinese medicine in the treatment of the case analysis, after the onset of the pigs treated with traditional Chinese medicine, the disease has been effectively controlled, after 10 days of treatment, the illness no further development, more than 80% pigs began eating, in good spirits, gradually restored. No medication of pigs to the further development of the disease, the signs of the whole does not improve, only about 30 percent of the pig began to feed, most pig standing instability, and ataxia. Symptomatic treatment group, the condition is not improved, instead than no drug control group is poor,10 days mortality up to 51%, no death of pig, only seven in a stable condition and the remaining 41 pigs poor spirit, difficulty in breathing temperature most has begun to decline that traditional Chinese medicine treatment in the early stage of the disease, can play a good therapeutic effect.[Conclusion] The middle or small scale pig farm to prevention and control of PRRS, first at the same time the PRRS vaccine and immune CSF immune, and the interval of at least two weeks, the effect can be guaranteed, good effect of traditional Chinese medicine in the treatment of PRRS, quick is a very good choice.
