Treatment of swine fever

Pig high fever is a disease with high morbidity and mortality, that is, pig nameless high fever syndrome. The main clinical manifestations of sick pigs are elevated body temperature, mental depression, loss of appetite or abstinence, dyspnea and wheezing. Some pigs are accompanied by symptoms such as red and purple skin, and a few pores have bleeding spots. Let's take a look at the treatment of pig high fever.

Characteristics of High Fever in Pigs

The main results are as follows: 1. it occurs in the season with high temperature, the course of disease is long, usually about 5-20 days, and the case fatality rate is high.

2. Pig farms do not attach importance to epidemic prevention, technical staff have a poor concept of health care, and pig farms without strictly closed pig farms and systematic health care for pig herds have serious disease.

3. The body weight of diseased pigs is generally 20-80 kg, and the incidence is the highest, and there are also piglets after weaning.

4. The effect of drug treatment is not ideal, and the mortality rate of pig farms with misuse of drugs is higher.

Clinical symptoms of porcine high fever

1. Growing and breeding pigs: growing and breeding pigs often show acute disease, with sudden lying on the ground, heavy breathing, obvious respiratory symptoms, severe individual pneumonia, later conversion to suppurative pneumonia and death due to respiratory failure.

2. Nurturing pigs and piglets: after the onset of the disease, the body temperature of nursing pigs and piglets increases, breathing is accelerated, accompanied by sneezing, coughing, runny nose, increased eye secretions, like clustering, like influenza symptoms, tolerant piglets are often accompanied by respiratory symptoms, emaciation, pale skin, rough coat, decreased resistance, easy to be secondary to other diseases.

3. Pregnant sows: individual individuals of pregnant sows have obvious symptoms of high fever, shortness of breath, lying on the ground, loss of appetite, and heavy fetal sows have miscarriage. The rest are generally paroxysmal hypopyrexia, showing loss of appetite, poor mental state, yellow urine, dry feces and so on.

4. Lactating sows: the incidence of lactating sows is not high, large groups show anorexia, individual severe respiratory symptoms, elevated body temperature, loss of appetite, lying on the ground can not afford, lactation decreased or disappeared, the reproductive function is affected in varying degrees after the course of the disease. The incidence of piglets during lactation is not high, and some piglets have symptoms of cough, fever and pneumonia.

Prevention and treatment of High Fever in Pigs

1. In order to prevent the purchase of recessive infected pigs, it is best to adhere to self-breeding. We should pay attention to the feeding and management of pigs and minimize all kinds of stress factors.

① should do a good job of heat prevention and cooling in summer, increase the ventilation rate of pig houses and spray with cold water, so as to promote evaporation and heat dissipation through convection. The doors and windows of the piggery should all be opened to let the air flow. When the temperature is high, wash the pig body with cold water or install a spray device, spray 4 times 6 times a day, and add ice cool feed to relieve summer heat and cool down.

The feeding density of ② should be reduced when it is hot. Growing pigs should have a living space of more than 0.8m2. The best breeding house should be 1.2m2 / pig, and the number of pigs in each column should be about 1012. Keeping reasonable feeding density and cooling can effectively control nameless high fever and respiratory tract disease of pigs.

③ strictly adopts the feeding method of "all in and all out" from delivery, conservation, to breeding, to avoid raising pigs with different ages in mixed groups, and to reduce the number of turning and mixed groups of pigs as far as possible, so that all pigs in the same pig house are transferred out at the same time. After each batch of pigs are out of the pen, the pig house must be strictly washed and disinfected, and then transferred to the new pig group after being left vacant for a few days.

2. The pig house and the environment should be disinfected with virus purifier regularly to reduce the content of pathogenic microorganisms. Disinfect with quicklime, plant ash water and chemical disinfectants once a day, and use a variety of disinfectants alternately.

3. To ensure that the feed is fresh and mildew-free, improve the nutritional level of pigs, and enhance the non-specific resistance of pigs. Honeysuckle, Artemisia annua, Herba Houttuyniae, Radix Isatidis, Radix Isatidis, Plantago asiatica, Artemisia annua, Artemisia annua, Phyllostachys pubescens, sweet mulberry leaves, wild chrysanthemum, big green leaves, loquat leaves, raw gypsum, cactus (to thorn and mash), earthworms, dandelions, Ichianxi and other mixed or single kinds of fried water can be used for pigs to drink or feed.
