The health status of sows. It not only affects the reproductive performance of sows, but also affects the health of the whole pig herd, thus affecting the economic benefits of the whole pig farm. Therefore, the health care of pig farms should start from the source, and the disease control of pig farms should start from sows.
This paper introduces the purpose of sow health care and the selection principle of sow health care antibiotics for your reference.
First, the purpose of sow drug health care is to prevent mother-to-child transmission. Control the vertical spread of diseases from the source. The second is to prevent sow endometritis, mastitis, agalactia or agalactia.
The medical care of sows mainly refers to the control of bacterial, viral and parasitic diseases, and viral diseases are mainly prevented by vaccination. Parasitic diseases are mainly prevented by regular deworming, while for bacterial diseases, antibiotics are mainly used at present.
Second, the common bacterial pathogens that harm pigs At present, the common bacterial pathogens that harm pigs mainly include mycoplasma, chlamydia, Eperythrozoon, treponema, Toxoplasma gondii (protozoa), Actinobacillus pleuropneumoniae, Haemophilus parasuis, Streptococcus, Staphylococcus, Escherichia coli and Corynebacterium pyogenes.
Among them, chlamydia, Eperythrozoon, Toxoplasma gondii, Streptococcus, Staphylococcus, Escherichia coli and Corynebacterium pyogenes are the most common pathogens causing reproductive disorders in sows.
Third, the selection principle of sow health care antibiotics generally follows the principles of broad spectrum, high efficiency, safety and low drug resistance.
Although different kinds of pathogens exist in different pig farms, many pathogens often coexist in the same pig farm, resulting in mixed infection of many pathogens. Therefore, we should consider the combination of drugs, make the combination of drugs broad-spectrum and efficient, and at the same time pay attention to the incompatibility.
Sows have high requirements on drug safety, and can choose drugs such as Zhiyuan Fu, Kangshumi (sulfachloropyridazine sodium), doxycycline, chlortetracycline, Linzhuang mycin, tylosin and amoxicillin. The following drugs should be carefully selected:
1, florfenicol. Pay attention to fake prevention. Fake florfenicol may contain chloramphenicol, which can cause aplastic anemia and is toxic to embryos.
2. Drugs such as sulfa -5- methoxypyrimidine or sulfa -6- methoxypyrimidine have strong renal and hepatic toxicity. Long-term use will lead to aplastic anemia
3. Ribavirin has strong cytotoxicity and hepatotoxicity. There are many cases of sow death caused by ribavirin poisoning in clinic.
