Effective prevention and control measures of common diseases of pigs

In addition to swine fever, swine flu, piglet paratyphoid fever, Haemophilus disease, diarrhea, in recent years, there are also epidemics of streptococcal disease, eperythrozoonosis and toxoplasmosis, which have produced some new diseases in summer. The changes and characteristics of the disease, so the diagnosis and prevention should be distinguished and paid attention. Here are some effective prevention measures:

1.Eperythrozoonosis of swine.

Pigs of different breeds and ages were susceptible, and the morbidity and mortality of piglets were higher. The disease occurs in the summer, spread and blood sucking insects, especially pig lice. In addition, injection needles, surgical instruments, mating, etc. can also spread. Stress factors such as poor feeding tube, bad weather or other diseases can cause recessive infection of pigs. It presents primarily with acute icteric anemia and fever. The production performance of sows decreased, piglets became worse, anemia, intestinal and respiratory infections increased. At the beginning of the fattening pig's illness, his body temperature rose39.5°C-42℃, trembling in circles or unwilling to stand, lying on the ground, constipation or diarrhea. Sick pig ears, under the neck, chest, under the abdomen, the inside of the limbs and other parts of the skin red and purple, finger pressure does not fade, become "red pig".

Although there are many kinds of drugs to treat this disease, there are not many effective drugs. Treatment with Xuezonjing, Imidazole Phenylurea, New Arsine and Sodium with Tetracycline, Oxytetracycline, etc.

2.Streptococcus suis disease.

More in spring and summer, sporadic infection. Infections, mainly through wounds or bites, contaminated by sick pigs are the vectors of infection. Mainly occurs in body weight10kg－30kgPiglets, with septicemia and meningitis type more common, in pig infection more common in suppurative lymphadenitis type. Sudden onset, eat little or no food, the spirit is not good, often pigs suffer from a cold fever after the secondary. Acute disease pig body temperature rises41Above ℃, diet or stop eating, conjunctival flushing, runny nose. Part of the disease occurred arthritis, claudication, crawling or unable to stand; some showed ataxia, empty molars and other neurological symptoms; some nape, such as extensive skin congestion or bleeding spots.8Piglets often die within two days of age. Pigs with chronic diseases often have large papules with round light rose coins on the head, chest, abdomen and medial skin of the thigh, which are covered with brown scabs. Mixed infection of swine fever, suffering from swine flow of serous nasal fluid, ear tip, under the abdomen, the end of the limbs, the medial side of the purple or blue-purple bleeding points, bleeding spots. Disease of the boar visible foreskin accumulation of urine, extrusion out of white, turbid, foul-smelling liquid. Sick pigs first constipation and then diarrhea or constipation diarrhea alternately appear, late dyspnea, often in1Days-3day of death.

In recent years, the pathogen of the disease has developed resistance to a variety of antibiotics, which has increased the difficulty of clinical treatment. But intramuscular injection of strong amoxicillin15mg/kgweight,2.5% Enrofloxacin Injection2.5mg/kgWeight, Daily1times, use together3Days, the disease will be effectively controlled. Mixed infection of swine fever, but also the whole group of emergency vaccination of swine fever vaccine.

3.Porcine toxoplasmosis.

This disease is more common in3month-old piglets,6The incidence of pigs over the age of months is less. It occurs in summer and autumn, and can be transmitted through the placenta, digestive tract, respiratory tract and blood-sucking insects. Sudden onset, often with flu symptoms, with a rise in body temperature40.5°C-42℃, missed fever, manifested as dyspnea, abdominal breathing, cough, runny nose, limb and body muscle pain, stiffness, large areas of the inner limbs and abdomen are reddish purple. Body surface lymph nodes, some diarrhea or constipation, and with mucus or blood, pregnant pig infection can cause abortion or death.

Sulfonamide-6-Methoxine, sulfadiazine plus trimethoprim and other sulfonamides are effective in treatment.

4.Eczema.

Swine eczema, also known as swine dampness, is mainly caused by long-term living in a humid environment. The incidence of high temperature season is more. Most of the acute cases are sudden. At the beginning of the disease, the skin on both sides of the pig's jaw, abdomen and perineum is red, with nodules as large as broad beans, itching and uneasy. Later, with the aggravation of the disease, blisters, papules and ruptures are often accompanied by yellow exudate, scabs and scales. If the acute pig is not treated in time, it often turns chronic, the pig's skin is thick and itchy, and the pig often wipes the wall to wipe the tree to relieve itching, resulting in hair loss all over the body. Often local infection, erosion or suppuration, long-term pig body emaciation, weakness and death. Do not accumulate fertilizer in the pigsty in high temperature season, but clean the pigsty frequently, keep the pigsty clean and dry, prevent rain leakage in the pigsty, and expose the bedding grass to the sun frequently. Wall humidity can also sprinkle some lime in addition to moisture.
