What causes pore bleeding after a pig becomes ill?
After a pig becomes ill, what exactly causes pore bleeding?
In recent years, when some high-fever diseases and major epidemics occur, bleeding from the pores of sick pigs is often seen, commonly on the ears, around the eyes, and on the back, with pinpoint to millet-sized bleeding spots, most obvious at the bristles on the neck.
Cause analysis
Pore bleeding in pigs is not an inherent symptom of the infectious diseases involved. Pore and internal organ bleeding occurs only when red blood cells in the animal's body are destroyed, granulocytes are reduced, and platelets are reduced. When we find pore bleeding in pigs, it is usually the situation after several days oftreatment. Looking at it now, quite a few materials and journals also list pore bleeding as one of the clinical symptoms of certain infectious diseases. They just repeat what others say. And whenever pore bleeding appears, it is considered a severe illness or an incurable disease, but this is not actually the case. First, from the perspective of infectious diseases, swine fever is pinpoint subcutaneous bleeding spots or bleeding patches that do not fade under pressure, while swine erysipelas is rhombic or irregular purplish-red patches raised above the skin that fade under pressure. Swine pasteurellosis, septicemic streptococcosis, Haemophilus parasuis, and others all present diffuse bleeding patches. And they each have their own unique clinical symptoms. Apart from swine eperythrozoonosis, in which red blood cells are destroyed by Eperythrozoon and pore bleeding occurs, other infectious diseases rarely have this phenomenon. Furthermore, when pigs develop high fever, using antipyretic drugs plus antibiotics is an indisputable fact. In fact, this phenomenon is all caused by improper medication.
Antipyretic drugs include traditional Chinese diaphoretic medicines and antipyretic-analgesic drugs (pyrazolone class and their derivatives). In particular, pyrazolones, although they have relatively strong antipyretic, analgesic, and anti-rheumatic effects and good efficacy, can cause reduced platelets and reduced granulocytes when used long-term in large doses. Pigs have underdeveloped sweat glands and cannot lower their temperature by sweating like humans. Once a pig develops fever, without determining the specific disease, antipyretic drugs are used indiscriminately and repeatedly. Little do people realize that fever is a protective response of the immune system that appears when the body is attacked by pathogenic microorganisms. At this time, we should use diagnostic methods and measures such as clinical symptoms, vaccine immunization status, disease epidemic season, disease characteristics, laboratory diagnosis, and when necessary necropsy...... to determine the disease and prescribe the right medicine. We should not blindly use antipyretic drugs fortreatment。
At present, veterinary drugs produced by veterinary drug factories are mostly compound preparations, and almost all contain antipyretic drugs (except for some targeted drugs). Some drugs are labeled as containing “Novalgin” or “Pyramidon”, which are actually metamizole sodium and aminopyrine. Surprisingly, some rural veterinarians and breeding personnel do not know what these are and treat them as miracle antipyretic remedies. Moreover, some veterinary drugs only state that they contain “special antipyretic ingredients”. Intreatment, in pursuit of efficacy, people often casually increase the dosage, or when using drugs in combination, drug A contains antipyretic-analgesic drugs and drug B also contains antipyretic-analgesic drugs. This unknowingly increases the dosage of antipyretic drugs. It causes pore bleeding in pigs.
When Itreatedrheumatism, after continuous use of antipyretic-analgesic drugs alone for several days, pore bleeding symptoms also appeared in pigs. And this has been verified many times. If VC or vk3 is added, the bleeding symptoms are significantly reduced, or there are no bleeding symptoms.
Solutions
1 When purchasing drugs, ask the manufacturer clearly about the active ingredients and content of the compound preparation.
2 Make clear the dosage of the drugs you use.
3 Prevent overdosage and repeated medication.
4 . If antipyretic drugs must be used, it is best to use vc and vk3 at the same time, which can both enhance the pig's immunity and prevent pore bleeding.
5 Choose drugs with a single ingredient, and it is better to compound the medication yourself according to the specific symptoms and condition.
