The weather gradually turns cool, compared with the natural disinfection of direct sunlight in summer, pathogenic microorganisms are more rampant in autumn. In addition, the temperature difference between day and night is relatively large, and the moisture causes stress to pigs, resulting in a great hidden danger of pig disease in autumn. It is suggested that the majority of farmers strengthen the management of pig farms, do a good job in pig disease prevention and control, and smoothly pass through the "troublesome autumn" of pig farmers.

First of all, the most important thing is to do a good job in the pig farm disinfection work, in and out of the pig farm to disinfect the whole body, it is best to change clothes into the factory. "Prevention is greater than everything" is a common saying in pig farms. At the World Pig Expo, delegates were told by leading pig experts about the four "pig diseases" and how to deal with them.

Determination of four common pig diseases

1. Symptoms of blue ear disease; Pregnant sows have high fever, anorexia, cough, different degrees of dyspnea, premature delivery, late abortion, stillbirth, fetal mummification, weak offspring, and delayed due date. Mental condition improved after abortion, but weakness, sometimes cyanosis of the skin, blue ears. The piglets became ill with dyspnea, dyskinesia, muscle tremor, slight eyelid edema and progressive wasting.

2. Symptoms of swine fever include: the body temperature of sick pigs rises to 40.5℃ to 42.5℃, and the body temperature of mild swine fever is high and low, mostly between 40.5℃ and 41℃. The spirit is sluggish, shivering, hunching, eating less, not eating, walking slowly, wavering, eye conjunctiva inflammation, and a large amount of sticky or purulent secretions. Constipation and diarrhea alternate, and there is spotty or patchy bleeding in the abdomen, limbs, and jaw.

3. Symptoms of eperythrozoonosis include: temperature rises to 41 ° C to 42 ° C after generally not eating for three days. Persistent persistent fever, mild panting, ear into purple red, late disease for purple red or red body to become red pigs, sick pigs highly anemia, manifested as skin mucosa pale or jaundice.

4. Para-pig symptoms include: common in piglets aged 3 to 10 weeks, acute symptoms of rough coat, severe fever, depression, loss of appetite, unwillingness to exercise, breathing difficulties, body curled up, abdominal pain, lameness, joint swelling. In the acute phase, the symptoms are relieved after 14 days of onset, and thereafter the main manifestations are joint swelling and lameness, which can last for more than two months.

Prevention and control programmes for four common pig diseases

1. Improve biosafety measures for pig farms. To ensure the health and safety of the introduced seeds; Early introduction of pigs, pay attention to quarantine feeding, after passing the quarantine, can be mixed into the large group feeding; Do a good job of pig farm isolation, prohibit pigs to buy vehicles, foreign personnel, etc., in and out of the pig farm at will. Other poultry should not be kept in the site to avoid interweaving infection of patients.

2. Do a good job in disinfection management, clean up the manure in the pig house, and use disinfection agents to disinfect alternately. Aisle and disinfection isolation belt, do regular disinfection.

3. Do a good job in reasonable vaccination. Get the right type of vaccine to prevent and control diseases. Anti-stress drugs, such as Cortisol in drinking water, are more effective in preventing stress during vaccination.

4. Strengthen feeding management, the appropriate temperature and humidity in the enclosure, at the same time, deal with the relationship with ventilation. Supplement clean water. The reasonable proportion of full price ration can select the appropriate feeding feed according to the different growth stages of pigs, and meet the nutritional needs of their growth and development. Pay attention to the control of pig breeding density, especially in autumn, reasonable breeding density, the effect of preventing respiratory diseases is much better.
