Do you understand several key links in the prevention and treatment of blue ear disease?

Blue ear disease

Generally speaking, it spreads slowly in some pig herds as early as March-April, the outbreak period is from June to September, and ends from the end of October to the beginning of December. it is necessary to pay close attention to the trend of pigs at this time.

Clinical diagnosis of blue ear disease

Generally speaking, the following stages are more conducive to the early clinical diagnosis of blue-ear disease, seize the opportunity for treatment, and have a more accurate understanding of blue-ear disease.

1) sows have loss of appetite, like lying, cough and asthma to varying degrees, frequent miscarriages, mummies, high weak rate, dyspnea, dyskinesia, external eight-character phenomenon in some piglets, umbilical cord and tail ulceration in some piglets, and the death rate of piglets within a week is on the high side, up to 40% and 80%.

2) after the general body temperature of nursing pigs increased for 3-5 days, it showed loss of appetite, abandonment, gradual aggravation of cough symptoms, increase of nose, more dirt around the nose tube, some pigs showed abdominal breathing, skin flushing, eye and face edema and so on.

Some pigs appear stubborn diarrhea, thirst symptoms are prominent, some serious pigs appear ear, neck and other parts of the body purple, vomiting, convulsions and circles, hindlimb paralysis and weakness. The mortality rate reached 20%, 40%, and 40%.

3) the susceptibility of fattening pigs is poor, only anorexia and dyspnea, a few ear cyanosis, purplish red bleeding plaques on the back and abdomen, which are easy to stimulate mixed pleuropneumonia and mycoplasma pneumonia.

Prevention and control of blue ear disease.

1) purify the breeding environment

Strictly implement the disinfection system, spray with 3% caustic soda empty ring and clean it one day later. During the epidemic period, pig houses can be sprayed with glutaraldehyde, povidone iodine and other disinfectant twice, including thoroughly disinfecting the appliances in the pig house once a day.

Strengthen the feeding and management, timely adjust the pig herd, improve the ventilation and lighting of the pig house, and reduce the pig feeding density of 1.5 square meters per pig. Abortion, stillbirth, non-estrus sows are eliminated in time to purify the blue ears of pig farms.

2) Scientific immunity

Formulate scientific immunization procedures, effectively do a good job in the prevention of conventional diseases such as foot-and-mouth disease, classical swine fever, circum, porcine pseudorabies, and so on, so as to put an end to the occurrence of the disease as far as possible.

Aiming at the pig farms with high incidence of blue ear, pathogen detection, vaccination with variants of the same and similar strains, blue ear vaccine is not recommended for sows in pregnancy, which is prone to mechanical abortion. at the same time, the virus may infect piglets through the placenta in the middle and later stages, resulting in high weak rate and infection in lactating piglets.

3) Mr. Tian of Secco Group recommends drug prevention and treatment.

Radix Astragali, Coptis chinensis, Huangling, Ganoderma lucidum, Radix Isatidis, Flos Lonicerae, Herbal Medicine and other traditional Chinese medicines have broad-spectrum antiviral and inhibitory effects on virus variation, mainly in the pre-and middle stages of infection, and have a good effect on mixed infection of viruses and bacteria.

In addition, it can antipyretic and anti-inflammatory, clear heat and cool blood, enhance immunity, repair immune system, improve microcirculation, and cooperate with tilmicosin and Tywanin to enhance the activity of pulmonary macrophages and block blue ear virus replication. finally achieve purification, treatment of blue ear effect.
