- - the method of controlling swine high fever
with the change of temperature, mosquitoes breed rampant, pig disease resistance decreased. in recent months, swine fever has been occurring in a small area in parts of hunan province". huge economic losses have been brought to the pig farm. through the comprehensive analysis and diagnosis research professor of domestic and foreign famous pig: this disease is a variety of pathogens (blue ear disease, swine fever, porcine circovirus pathogen, eperythrozoon, toxoplasma, streptococcus disease) mixed infectious disease.
pathogen analysis
prrs has a specific affinity for macrophages and macrophages. macrophages are responsible for phagocytosis of bacteria and viruses invading the body, and have immunological functions. the macrophages then failed to kill the blue ear virus. in contrast, prrs viruses proliferate in macrophages and cause macrophages to die. the virus will always exist after invading the pig and can be activated at any time.
classical swine fever virus (csfv) mainly plays an important role in the proliferation of immune organs and lymph nodes in the body, and destroys the defense function of the immune system.
porcine circovirus porcine circovirus (pcv ii) can cause the immune system against pig, pig body immune suppression and decreased resistance, interference and damage to other pig produce and maintain disease antibody, thus secondary to other diseases simultaneously.
eperythrozoon, toxoplasmosis altered red cell surface structure, the deformation of pathogens can also make the red blood cell antigen denaturation, resulting in autoimmune hemolytic anemia; blood coagulation disorders caused by severe, hemorrhage; glycolysis strengthened, glucose consumption, lactate production increased, resulting in hypoglycemia and acidosis; the destruction of a large number of red blood cells, immune suppression.
streptococcal disease under natural conditions, pigs by respiratory and digestive tract infection, pathogenic bacteria can invade the lymph and blood circulation through the mucosa and tissue barrier quickly, and in the blood and tissues rapidly proliferate and produce toxins and enzymes, and death due to structural damage and function of body defense barrier and collapse the brain, spinal cord, liver, kidney, heart and other essential organs disorders.
to sum up, it is not difficult to see what they have in common
virus disease mainly destroys the immune system of animal body and interferes with the immunity of organism, thus forming immunosuppression and greatly reducing the disease resistance of animals.
protozoan disease mainly destroys the blood circulation system of animals, and changes the surface structure of erythrocyte, resulting in autoimmune hemolytic anemia, hypoglycemia and acidosis.
bacterial disease - the animal body's immune system damage, streptococcus, infectious pleurisy, resulting in secondary mixed infection take advantage of a weak point.
two 、 clinical symptoms
1, high temperature 40.3~42 degrees, the whole group of sudden onset (2 - 3 days), severe anorexia, skin flushing, purple, hemorrhage, bleeding spots.
2, voice hoarse, unwilling to move, such as dry stool with spherical outside blood, yellow urine, ear tip becomes dry and rolled up to the late, cyanosis, recumbency, do not eat, only drink water or urine etc..
3, eye redness or purple, conjunctivitis, dyspnea, runny nose or thick nose. weak limbs, some slight cough, some vomiting, and some showed neurological symptoms. the death process is very fast.
4, sow depression, loss of appetite or waste vast, panting, cough, dyspnea; pregnant sows of premature birth, abortion, stillbirth, fetal mummification, weak piglets.
5, neonatal pig body temperature 40 deg c, dyspnea is abdominal breathing, do not eat milk, yellow diarrhea, muscle tremors, ataxia, paralysis, claudication. to the late individual disease of vulva, pig ear, tail, waist cyanosis, limb distal skin purple plaque and other symptoms.
three 、 pathological examination
90% of the gastrointestinal tract is damaged, and the stomach wall and intestines are congested, bleeding, ulcer, gall bladder filling or empty. lymph node hemorrhage, enlargement, marble lesion, splenomegaly, enlargement of lung, enlargement of stroma, soft and weak color of heart muscle. there is a large amount of foam or purulent discharge in the trachea. some visible kidney needle like bleeding, some showed hepatomegaly and necrotic.
four, health care prevention
1, high immunity platoon toxin and three disease elimination (even mixing)
2, the immune peptide of fu fu and astragalus root (evenly mixed)
for any of the above options, refer to the following usage
the 200g mixture of 400kg, for the 7-10 sow prenatal and postnatal day ad libitum.
the 200g mixture of 400kg, for the weaning piglets before and after 7-10 days, ad libitum.
the 200g mixture of 400kg, for fattening pigs and boars per month for 7-10 days, ad libitum.
3, to undertake scattered and three disease epidemic febrile disease elimination immune interferon (mixed)
4, avoid high row toxin fluoride xingkang (odd aphagia or who can be administered through drinking water) (mixed)
the above options are optional (used on a scalar basis) for 7-10 days a month
5, experts recommend large and medium-sized farms disinfection, the first drug - plague tyrants (used by scalar)
summary: to strengthen scientific management, increase the pig body resistance, scale raising and closed management, ventilation and disinfection, cooling fan heatstroke and environmental health, etc.. the sports field is set up and cool shade, shade net, anti mosquito bites and stings.
five 、 comprehensive treatment
morning fever tratch mixed and mixed feeling full treatment mixed injection
the afternoon of morninglight honggong chain and blood mixed clearing point injection
(all the drugs are strictly used on a scalar basis)
