1 mixed infection of swine streptococci
Pigs are susceptible to this disease after a cold. In acute pigs, the body temperature rises above 41 °C, and the appetite is reduced or abolished. Conjunctival flushing, runny nose. Some sick pigs are limp, crawling or unable to stand due to arthritis, and some show neurological symptoms such as ataxia and empty molars. Sick pigs have constipation after diarrhea or constipation diarrhea alternately, late breathing difficulties, often die within 1 to 3 days after the onset.
Treatment: Early injection of vaccine can effectively prevent the disease. After the onset of the disease, the use of potent amoxicillin, ofloxacin, enrofloxacin and other drugs can effectively control the disease.
2 Eperythrozoonosis (erythroderma)
The typical clinical symptoms of the disease are decreased sow production performance, poor piglet physique, anemia, increased intestinal and respiratory infections. The fattening pig has a mental illness at the beginning of the disease, and the body temperature rises to 39.5 to 42 °C. It is trembling or not standing, lying in the ground, constipation or diarrhea. The skin of the sick pig's ear, the neck, the chest, the abdomen, and the inside of the limbs are red and purple, and the finger pressure does not fade.
Treatment: bloodworm net (Benil), arsenic acid combined with long-acting oxytetracycline, supplemented with drugs or feed additives for feeding blood.
3 gastroenteritis and porcine epidemic diarrhea
Both of these diseases are viral infectious diseases. Generally, every 2 to 3 years is a disease cycle, but since the disease law is difficult to grasp, it is necessary to vaccinate the sows when entering the fall.
Treatment: If the disease occurs, adult pigs can be injected with antibiotics and supplemented with vitamins, which can be recovered by medication for 5 to 7 days. However, young pigs that are not weaned have an infection, and the mortality rate is high and there is no specific treatment.
4 Porcine Reproductive and Respiratory Syndrome (Blue Ear Disease)
The appetite of the sick pigs decreased, and the fever reached 40.5 to 41 °C, which made it difficult to breathe. Pregnant sows have miscarriage; movement disorders and circling disorders; boar libido; lactating pigs born with weak fetuses, depressed, weight loss, valgus leg posture; difficulty breathing, conjunctival edema, individual piglets with tremor symptoms; weaning Piglets and growing pigs showed persistent anorexia, depression, difficulty in breathing and skin congestion, and purpleness in the ears, lower abdomen, and hind legs.
Treatment: Once the farm is ill, the sick pigs and the healthy pigs should be kept in isolation as soon as possible. The waste and the sink are strictly separated, and the pigs cannot contact each other to prevent infection. Symptomatic treatment for sick pigs: penicillin 20,000 IU / kg, chlorpyrifos 0 · 1 kg, 2 times / day, 7 days for a course of treatment to relieve symptoms and prevent secondary infection. Pregnant sows can try traditional Chinese medicine to clear away heat and detoxify, prevent miscarriage: Angelica, rehmannia, fried white peony, Miao Ai, clam shell, motherwort, honeysuckle, magnolia, moxibustion licorice, decoction prevention, once every other week, once every two times.
5 pseudorabies
The disease can lead to a large number of deaths in suckling piglets, sows, abortion, mummified fetuses and infertility. Mandatory immunization measures can be taken: two immunizations are performed after the introduction of the breeding pigs, 4 weeks apart; the pregnant sows are immunized 4 weeks before delivery, the boars are immunized twice a year, and the weaned pigs are immunized once every 8 weeks and 12 weeks.
There is no specific treatment for this disease. For infected pigs, pigs can be injected with pseudorabies high serum, which has obvious effects on weaned piglets. At the same time, it is treated with Astragalus polysaccharides. Emergency immunization of pigs that are not affected by the disease.
6 Toxoplasmosis
The body temperature of the pig is raised to 40.5～42°C, the heat is reserved, the breathing is difficult, abdominal breathing, coughing, runny nose, limb and muscle pain, stiffness, large area of ​​red and purple on the inside of the limbs and the abdomen, surface lymph nodes Swollen.
treatment:
Methionine tablets: 0.074 grams per kilogram of body weight, orally, 2 times a day, 5 days for a course of treatment, the first dose doubled.
Sulfadiazine injection: 0.07 g per kg body weight, intramuscularly, once daily.
Sulfonamide 6-methoxypyrimidine: 60-100 mg per kilogram of body weight, once a day for 3 to 4 days.
Synergistic sulfa 5-pyroxine injection: intramuscular injection of 0.2 ml per kg of body weight, 2 times a day for 5 days.
Long-acting sulfonamide: 50 mg per kilogram of body weight combined with sulfadiazine, orally, once a day for 3 to 5 days.
7 piglets
The swine fever is dominated by mild and atypical. If the vaccine is of poor quality, the immunization schedule is unreasonable, the injected dose is insufficient or the operation is not standardized, even if the swine fever vaccine is injected, it may be ill. If the sows have not been injected with the swine fever vaccine (single seedling, double seedling or triple seedling), lactating piglets are likely to have unnamed fever, constipation, skin blemishes, dirty water, good appetite, late squatting, etc. disease. Sows have been injected with swine fever vaccine. Piglets that are not weaned do not have swine fever. If the piglet is vaccinated within 6 weeks after birth, the immune failure will be caused by maternal antibody interference, until the piglet, shelf pig and finishing pig At the time, atypical swine fever can occur.
There is no specific treatment for this disease. The reference method is to attack with poison: to inject more than 10 times more than the preventive dose of porcine sputum to stimulate the body to produce interferon, interfere with the replication of the swine fever virus, and make it immune.
8 porcine lung disease
The body temperature of the pig is raised to 41-42 °C, breathing is difficult, it is in a dog sitting posture, red spots appear in the abdomen and abdomen, the neck under the throat is swollen, the palpation is hard and hot, the mouth and nose flow white foamy mucus, diarrhea, weight loss .
Treatment: ciprofloxacin hydrochloride 25 mg per kilogram body weight, plus 1000-2000 ml of normal saline, ear vein infusion, recovered after 5 days.
9 flu
The disease mostly occurs in late autumn or after a sudden change in temperature. After the pig has got the flu, it often becomes the "source of all diseases", especially the symptoms such as elevated body temperature and cough, which will become a precursor or cause of many diseases. If not controlled in time, it will cause immeasurable losses.
10 rheumatism
The disease is mainly caused by factors such as thief wind, wet house, cold and other factors. There are obstacles in the functioning of the affected herds, and there are more pigs with lumbar back and rheumatism in the limbs. The performance is that the waist is as hard as the board, the movement is not flexible, the initial adhesion step, slow and short steps, the limbs can not stand up after the disease is aggravated, the lying can not afford , forcibly lifted up, limbs and muscle tremors. The body temperature is slightly higher and the appetite is diminished. Screams when the pain is severe. If it is treated early, it is easier to cure. Strengthen the management of pigs, strictly prevent wind, cold and wet invasion, increase ventilation and ventilation, timely remove waste, sludge and turbid water in the circle to keep the ground dry and clean. Thickening of grass, cold protection and other measures are the focus of autumn pig breeding work.
treatment:
Prescription 1: Cortisone acetate injection 1 time 2 ~ 4 ml (50 ~ 100 mg), 1 intramuscular injection; oral administration of sodium salicylate tablets 2 ~ 5 grams and sodium bicarbonate tablets 2 ~ 5 grams, 2 per day Second, for 2 to 3 days;
Prescription 2: Compound sodium salicylate injection 20 ~ 50 ml, 1 ear intravenous injection, once a day, once every 2 to 3 times.
