Disease prevention of farmed pigs: pig "erythroderma" treatment technology!

Porcine erythroderma is caused by the invasion of porcine erythroglobulin cells transmitted by mosquitoes and flies into the blood of pigs, and its epidemic is obviously seasonal. generally, it is hot and humid from May to June every year, mosquitoes and flies proliferate suddenly. Here's about the disease prevention of farmed pigs: pig "erythroderma" treatment technology!

I. the pathogen of porcine erythroderma

Porcine eperythrozoon has no seasonality and can occur all the year round, but the incidence is higher in summer and autumn. It is speculated that it is transmitted through blood-sucking insects, contaminated needles and instruments, mating and other pathways. Adverse environmental conditions, bad climate, various stresses, concurrent infection and other factors are the decline of pig immune function, which can stimulate the outbreak or aggravate symptoms of recessive disease pigs. The disease can occur in pigs of all ages, but piglets and shelf pigs are more common, and the mortality rate is higher. Sows are susceptible to the disease due to the decrease of resistance after delivery, mainly characterized by pore bleeding, stubborn anorexia, but the mortality is not high.

2. Clinical symptoms of porcine erythroderma

1. Acute onset: high fever, death within half an hour, death of the whole nest within 2 days, sudden lying down, lethargy, convulsions of limbs, poor appetite or abstinence, body temperature above 40-41 ℃, purple-red spots, finger pressure does not fade.

two。 Chronic disease: diseased pigs showed loss of appetite, cough, dry stool, pale conjunctiva, cyanosis in both ears, cold and dry ear tips, and a long course of disease.

3. Piglets and fattening pigs suffer from the disease: the earliest symptoms are fever, body temperature can reach more than 40 ℃, high fever, shivering, gathering and stacking; food intake decreases significantly, showing red skin all over the body, commonly known as: porcine erythematosis, some ears, abdomen, limbs first turn red and then purple spots; a month later, piglets turn into anemia, jaundice, growth retardation, become stiff pigs or die within a few days.

4. The incidence of sows: the main symptoms were body temperature above 40 ℃, high fever staying for several days, anorexia, constipation, diffuse redness all over the body, unwillingness to stand, easy miscarriage or increase in the number of stillbirths in the later stage of pregnancy, weakness, pallor and jaundice in some sows, mastitis, no milk or insufficient lactation after delivery.

III. Prevention and treatment of porcine erythroderma

1. Prevent the spread of insect vectors

Attention should be paid to spraying insecticides in summer and autumn to drive away or eliminate blood-sucking insects. All pig sheds should be injected with avermectin once; all pig houses, especially warm nurseries, should be sprayed with Meisaoling once a day for 3 days, or spray pig houses and pigs with mosquitoes and flies, once every 5-7 days, the insecticidal effect is better; although it is difficult to completely eliminate insects in pig sheds, it reduces the transmission of pathogens between pigs and pigs, thus reducing the incidence of pigs.

two。 Regular drug prevention and treatment

Drug prophylaxis is one of the important methods to control the occurrence of swine disease, which can effectively reduce the incidence of porcine eperythrozoon. Drug prophylaxis can be mixed into feed, fed with Fuzheng and immune housekeeper, 500g, 500kg, mixed probiotics, 1000kg per 1000g, for 5 days, the first dose is doubled.

The above is the introduction of the prevention and treatment of porcine red skin disease by the soil flow net, and the hygiene, temperature and humidity control, disinfection and other aspects of the pig house must be paid attention to, which can not only reduce the occurrence of porcine eperythrozoonosis, but also greatly reduce other pig diseases.
