Expert, veterinarian of animal husbandry, point out section pig influenza high to take place season summer and autumn, if does not prevent and control well, will probably lead to the fact this disease happens big.
There are many risk factors
Cause pig influenza taking place and prevailing risk factor to be numerous, can sum up for 3 respects on the whole: First, human factor, second, the weather factor, third, environmental factor.
Crude free from worries and petty ideas formula raise management, cause and have illness coming on: Peasant households have taken care of the crops in the field and neglected the pig in enclosing during summering harvest, two autumn harvests busy farming season season, give pig play thimble of epidemic prevention in time, give pig feed in time, make pig full first hungry first, do not give and enclose and give up and sweep hygiene,etc. in time, can cause pig's body resistance to drop and cause and have illness coming on. Raising the family scattered of a lot of areas in our city, locate the pig low and moistly, ventilate the bad, dirty and muddy one and simple and crude to enclose and raise while giving up, the pig is unable to avoid the invasion and attack of heat and cold rain, can't avoid and suck the biting of the blood insect, in addition, feed to go bad corrupt water from washing rice type feed, how could the pig have illness coming on?
Epidemic prevention is uncomplete to result in having illness coming on: In recent years, in a lot of area administrative structure reform, the rural veterinary station of animal husbandry at the basic level is cancelled or merged, make the veterinarian service system line at the basic level break the network broken, cause paralysing or half a paralysis state of animal epidemic prevention, appear pig birds thimble of epidemic prevention have people play and place of production quarantine situation which no one engaged in, thus cause pig's influenza to have illness coming on.
Peasant households serve as the veterinarian and make the bitter pill by oneself: In quite a lot of areas, peasant households serve as veterinarian's phenomenon by oneself generally. They depend on the preventive treatment knowledge of of animal that have half knowledge, buy syringe and daily medicine, see pigs do not eat the food to have an injection to use medicine for pigs. The most people in them do not understand the immune procedure, knowing how to diagnose and mechanism of using medicine, their often flurried trick while finding animals serious, and then go to look for the veterinarian to make a diagnosis and give treatment. Operating so not only can not defend the disease, but also pig's disease often rises one after another constantly all the year.
It causes the vicious circle that freedom is slaughtered: A lot of peasant households see the sick pig have several injection and disappear to take a favorable turn, sell the disease pig cheap knife hands to slaughter. The knife sells the pork of disease on the market, make the condition spread to spread in larger range. If the hotel will contain pathogens ( maliciously) Water from washing rice last countryside, feed by pig,it is have illness coming on to last more pig. Therefore form the vicious circle, often make the prevalence of the disease take shape many times repeatedly or rise one after another, can't control for a long time.
It is apt to guide and catch complication
Until the intersection of pig and influenza prevail the intersection of disposition and condition investigate verse regard pig's influenza as guide often summer and autumn in recent years, and then initiate a lot of complications and continue hair disease, for instance: Swine fever, pig's lung epidemic disease, piglet's paratyphoid fever, pig infective pleura pneumonia, streptococcus suis,etc.. Among them most easy to erupt simultaneously or it continues takes place to be pig's infective pleura pneumonia. According to investigation, in the the intersection of verse and the intersection of pig and disease, influenza is often the root of the trouble in one summer and autumn such as area, it happen and carry on, take place or often make the condition complicate with its complicated disease first, bring very high morbidity, mortality and eliminating rate to pig group.
Sterilize and kill the source extremely urgently
How to prevent pig's influenza from taking place big? Personnel, veterinarian of animal husbandry, point out, warm and high in solar terms in summer and autumn, spend high-temperature season sterilizing and killing the source, can get up to preventing and curing pig's influenza to the result of getting twice the result with half the effort. County the intersection of township and two the intersection of veterinarian and the intersection of epidemic prevention and organization should utilize high-temperature season fully, organize peasant go all out with, sterilize, kill the intersection of source and activity, eliminate the pathogen effectively. The related departments should enforce the law strictly, attack and slaughter and kill the behavior privately excessively sternly, forbid selling and slaughtering the disease pig, prevent diffusion of cause of disease. At present, all parts should well implement the State Council " suggetion on advancing the reform of veterinarian's system " ,Improve animal's service system of epidemic prevention, mend the present epidemic prevention gap conscientiously really, do a good job of the animal epidemic prevention conscientiously.
