Seasons alternate, beware of sheep pleuropneumonia
Currently at the turn of the seasons, sheep pleuropneumonia is prone to disease. The survey found that in addition to suckling lambs, the incidence of pleuropneumonia accounted for about 40% of the entire flock. Therefore, farmers should pay attention to the prevention and treatment of pleuropneumonia.
The disease is a respiratory infectious disease caused by Actinobacillus pleurisi. It is clinically manifested as pneumonia and pleurisy with typical symptoms and lesions, most of which are acute and die suddenly, and some are chronic or debilitating weight loss. In particular, it is more prone to disease under the action of congestion during transportation, sudden climate change, poor ventilation and other stress factors, and toxins produced by germs can cause severe lung damage.
This disease mostly occurs in spring and autumn, and is closely related to crowding, poor ventilation, and humidity. Rehabilitation sheep can carry the bacteria for several months. Pathogens are spread over short distances via droplets or aerosols, and are most easily spread under conditions of high intensive breeding. Sheep are highly specific hosts. Sheep of all ages are susceptible, and the shortest incubation period is only 12 hours. The acute incidence rate is 8%~10%, and the fatality rate is 0.4%~100%.
1. Diagnosis points
Easily confused diseases: Streptococcus, sheep pneumonia, chronic
Sexual cases and asthma.
2. Prevention measures
①Strengthen the prevention of flocks and detect diseases
Sheep should be isolated and handled in time.
②Strengthen feeding management, pay attention to ventilation
Keep the air clean and fresh in the house. Reduce the influence of various stress factors and maintain adequate and balanced nutritional levels of the sheep. Reduce the degree of feeding.
③Using the "all-in and all-out" breeding method, the stalls are thoroughly cleaned and disinfected after the sheep are sold, and the stalls are left empty for a week before reuse.
④ Use double-stranded quaternary ammonium salt disinfectant to disinfect the entire sheep farm, including utensils. Prevent disinfection once every 10 days, once a day when onset, and disinfect for 5 consecutive days.
① Penicillin, amoxicillin, tilmicosin, tetracycline, etc. have therapeutic effects on this disease. Once a sheep becomes ill, immediately isolate and treat it with 10% florfenicol injection + dexamethasone mixed injection, once a day, twice a day. At the same time, all sheep in the entire sheep farm were fed with 1500 grams of amoxicillin per ton of feed for more than one week.
②Inject florfenicol, lincomycin or penicillin and other drugs into the sheep in the same pen. In order to reduce the stress caused by catching sheep, while taking the drug for 2 days, choose drinking water or mixing with the above drugs for more than one week. . While effective treatment can prevent new cases from appearing.
③The effect of drug treatment on chronic disease sheep is not ideal. It should be noted that although antibiotics can reduce mortality, the diseased sheep after treatment are often still carriers.
