How to prevent high fever in pigs?

Since the summer, the weather has entered the hot summer with high temperature and high humidity, and the thermal stress of pigs has gradually increased. The main reason of high fever is that pigs in pig farms are generally in sub-health state, and their physique is low, so high fever will occur under high stress. In view of the current epidemic causes and characteristics of high fever, Aobang Bio has summarized a set of effective prevention and control programs, which will provide effective help for the prevention and control of the disease in pig farms.

The course of high fever is longer, usually 5 to 20 days, and the mortality rate is higher, especially in suckling pigs, which are higher than in previous years, reaching 80% and 50% respectively. Symptoms are similar to those in previous years. Sick pigs usually have a high fever of 40℃ or even 42℃, and they start to eat less, lose appetite or even give up eating, and their spirits are sluggish and their water consumption is reduced. The skin is red and purple, the tail is bleeding and blood stasis, and some sick pigs have diffuse erythema all over the body, accompanied by severe dyspnea, abdominal breathing or sitting dog breathing, shortness of breath, and some show panting or irregular breathing; Digestive system disorder, diarrhea or constipation; Seriously ill pigs die of organ failure quickly, and pigs with a long course of disease are difficult to cure, and eventually become stiff pigs or die of chronic consumption; Some sows have miscarriages, stillbirths, weak offspring and fetal mummies in the third trimester.

According to epidemiology, clinical symptoms and laboratory test results, this epidemic situation is still a mixed infection or secondary infection caused by multiple pathogens. The main pathogens are: classical swine fever virus, blue ear virus, circovirus, Haemophilus parasuis, pleuropneumonia, mycoplasma, Eperythrozoon, Toxoplasma gondii and Streptococcus. Many diseased pig farms have multiple pathogens at the same time, and some pig farms are dominated by 2 ~ 3 pathogens.

Treatment plan: high fever legend is injected into muscle once or three times alone, and plenty of water should be ensured during treatment.

Avoid by all means: do not use drugs indiscriminately during the period of high fever, especially hormones, dexamethasone and sulfonamides, which have high mortality; Don't take a large dose of vaccine after illness, as long as it is vaccinated, it will be counterproductive.

In the course of treatment, it should be noted that the legend of high fever is octa-immunoglobulin. If the temperature exceeds 40 degrees, Bupleurum, Qingkailing and Radix Isatidis can be used together with this medicine. After two or three days, the appetite will recover. Livestock should ensure adequate drinking water during treatment. This product can be injected into the subcutaneous tissue of muscle, and the drug can be released slowly for up to seven days.
