deductive thinking on controlling swine diseases
add time:2014.03.22    views:765

in recent months received several farms on continuous pig calls, some even ask too many people come to no avail diagnosis. i'd like to talk about one of my personal views on one of the special cases.
first of all, i think the best doctor is pig pig (breeder), why? because the cause of disease process only know pig people most clearly, they have the most detailed, the veterinarian or foreign experts understand the situation are very limited, only by experience and imagination is not exhaustive, this is not to say that there is no place for wuhan technology experience, on-site diagnosis must fully collect details, especially. and the management of visits of people may not see the problem.
a southern pig farm, there are hundreds of pigs and sows, piglets have 600 long, from november 100 to 200 pounds of fattening pigs of onset, the main symptoms of swine respiratory difficulties, some have a fever, redness of the skin, the size change is not too large, the individual has diarrhea. according to the swine epidemic prevention of swine respiratory disease syndrome medicine, successively through drinking water, mixing, injection with mycoplasma net, tylosin, lygo, florfenicol, doxycycline, roxithromycin, rifampicin, enrofloxacin, multidimensional, herbs and so on, from the last month with the drug situation (mix feed a week withdrawal 2 - 3 days), about the use, but the actual situation, the pig almost every day the death of 1 - 3, some of the previous night seems fine, but also have some material, died second days.
after dissecting death, the main pathological changes of the myocardium are bleeding, pericardial effusion, pulmonary edema, bleeding, lymph node bleeding, liver swelling slightly, small intestine hyperemia or bleeding point.
because i can not go to the field (inter provincial inconvenience), after understanding that the site was remote, the hog cholera vaccine was done two times with the spleen vaccine. all the feed products are processed from the commodity premix, and the feeding and management personnel have no change after being treated with mildew. at the same time, not far from the 200 long conservation pigs basically safe, so far seems to have no reason to be checked......
only can think of to ask again, look at the big pig and nursery pigs where on earth is not the same, ask questions are finally taking shape. the field of special geographical conditions, very dry, pig drinking groundwater pumped wells, while the big pig is drinking pond water, and feces are dealt with directly into the pond, the back of the analysis i think as can be imagined, we will do a few 1 1=.
pig management is a top priority in pig farming. i see the light for reading jun xiao long.
