A kind of medicine of pure treatment by Chinese herbs porcine hyperthermia
Technical field
The present invention relates to the veterinary and use medicine, a kind of specifically medicine of pure treatment by Chinese herbs porcine hyperthermia.
Background technology
It is one of major industry of China's animal husbandry development that ecological pig produces, also be a main pillar of China livestock products foreign exchange earning, be aspect increasing national income and uplifting the people's living standard, accelerate the important goal of aspects such as farming and animal husbandry development, adjustment agriculture industrialization structure.Yet, since 2006 by the end of May, numerous pig farms from south to the north, pig is bred in growth and part sow, nursery pig have broken out unknown high fever of pigs, the pig sickness rate is suffered from more than 50% in most of morbidity pig farm, and mortality rate has caused serious economy loss for the pig farm and the family of raising pigs up to 50~90%, some pig farm even therefore go bankrupt, people are with one's hair standing on end once talking " heat ".
" porcine nameless high-fever " is high fever syndrome of pigs, it is the equal disease with high of a kind of M ﹠ M, mainly occur in finishing period pig and part sow, the clinical temperature of pig body of 1. falling ill that mainly shows as of sick pig is increased to 40~42.5 ℃, spirit is depressed, and feed intake descends or appetite is useless cuts off, and trouble Corii Sus domestica skin is rubescent, behind the ear in one's ear edge cyanosis, abdomen down and health many places skin such as extremity tip the speckle shape is arranged, be aubergine; 2. dyspnea, happiness is lain prostrate, and serious ventral breathing appears in the part pig, and asthma is rapid, and the performance that has is breathed or is irregular breathing; 3. part is suffered from pig rhinorrhea, sneeze, cough, discharge of eye and is increased, and most of pig has the tear speckle, the conjunctivitis symptom occurs; 4. part swinery constipation, feces is constipated, is spherical, yellowish urine and less, muddiness, color burn.The sick pig whole body that the course of disease is long slightly is pale, the anemia phenomenon occurs, and disorderly thick by hair, myasthenia of limbs behind the sick pig of part can not be stood indivedual sick pigs are dying before, and last whole body is twitched and extremely.Morbidity swinery mortality rate is very high, the pig farm that has even up to 50~90%.The part sow miscarriage occurs in later stage of pregnancy (100~110 days), produces stillborn fetus, weak son and mummy.
Its characteristics of incidence is: 1. occur in temperature higher season, the course of disease is long, generally about 5~20 days, and the case fatality rate height; 2. the pig farm to epidemic preventing working think little of, technical staff's idea that keeps healthy is poor, do not have strict sealing pig farm, swinery not to be carried out the pig farm morbidity of health care of system serious; 3. fall ill the body weight of pig generally at 20~80kg, sickness rate is the highest, and the piglet morbidity after the wean is also arranged; 4. medication effect is not ideal, and the pig farm mortality rate of abusing medicine is higher.
The characteristics of porcine hyperthermia " three-hypers one is low " are that fever, sickness rate height, mortality rate height, cure rate are low.This disease is a kind of height contagious disease, ill pig and be the important source of infection of primary disease with malicious pig, and main route of transmission is that contact infection, air borne and seminal fluid are propagated, and also can pass through the Placenta Hominis vertical transmission.But number of ways such as susceptible pig per os, nasal cavity, muscle, abdominal cavity, vein and intrauterine inoculation and infective virus, 2-14 week all can be given other susceptible pig with virus disseminating by contact behind the pig infective virus.Flowing of infected pigs also is important circulation way.
Country adopts antibiosis prevention and control usually at present, to the swinery of pig hyperpyrexia is taken place, adds Florfenicol+sulfamonomethoxine 300 gram/tons in feedstuff per ton; Feedstuff reduces because ill swinery searches for food, and can not absorb the medicine of enough therapeutic doses, and dosing in drinking-water is simultaneously used the effective antibiotics of antibacterial and virus, allows swinery freely drink 5~7 days.Or a pig isolated rearing to having fallen ill, use sulfamethoxyplridazine class injection to carry out injection for curing, or with 80% Tiamulin, 125 gram/tons+chlortetracycline 300 gram/tons+ampicillin 200 gram/tons, or injection florfenicol, doxycycline, ampicillin etc., or cut off the horizontal transmission of disease between piglet and piglet.This cause of disease is responsive to above used chemical drugs, but toxic and side effects is big, and carcinogenic teratogenesis is in various degree arranged.To state of an illness especially severe and the not good sick pig of therapeutic effect, electricity can only resolutely be eliminated.
The Ministry of Agriculture makes the industry standard (NY5029-2001) of " pollution-free food-Carnis Sus domestica ", has stipulated organoleptic indicator, physical and chemical index, microbiological indicator of nuisanceless Carnis Sus domestica etc.It is more and more higher to the appealing of nuisanceless Carnis Sus domestica that " clenbuterol hydrochloride " incident of in March, 2011 exposure just can embody people, so the equal toxic side effect of chemical drugs has very big harm to people's health.The present invention is a pure Chinese medicinal preparation, does not contain any antibiotic, and chemical hormone etc., have no side effect at noresidue, and are safe, are the environmental type preparation.
