Winter is a season in which pig respiratory diseases occur frequently. These diseases have similar clinical manifestations and are difficult to diagnose. Therefore, understanding the clinical symptoms of each disease and comparing similar diseases is the key point for accurate diagnosis and prevention and control of diseases. We will often have frequent attacks in winter. The five diseases of the respiratory tract were discussed separately, and the new technology of pig breeding in combination with the golden baby dry fermentation bed (for details, please click), to help the farmers in a timely manner to prevent and control, reduce economic losses.
Porcine reproductive respiratory and respiratory disorders in pig respiratory diseases
Porcine reproductive respiratory and respiratory syndrome, commonly known as "blue ear disease." It is one of the major infectious diseases that endanger the swine industry. It is mainly a kind of respiratory infectious disease caused by porcine reproductive and respiratory syndrome virus. It spreads rapidly and has a high mortality rate. It is susceptible to pre- and post-weaning piglets. Mortality can reach 40%-100%.First, the clinical symptoms of pig reproductive respiratory and respiratory syndrome symptoms of boar after infection, respiratory shortness and dyskinesia is also lack of energy, loss of libido, sperm quality. After the sow became infected, symptoms such as anorexia, elevated body temperature, shortness of breath, runny nose and other similar colds appeared initially. A few (2%) infected pigs had extremities, tails, nipples, vulva, and blisters on the tip of the ear. Individual sows are diarrhea, and later on symptoms such as quadriplegia, generally last 1 to 3 weeks, and may eventually die due to failure. Pre-pregnancy sows miscarried, mid-pregnancy sows had stillbirths, mummified fetuses, or births of weak and deformed fetuses; lactating sows had no milk after giving birth; suckling pigs were starved to death; some neonatal pigs suffered from dyspnea and dyskinesias. Fear, died within a few days.
The piglets before and after weaning are most susceptible to infection, most often appear as rough hair, lack of energy, difficulty in breathing, wheezing or ear cyanosis, and some have bleeding tendency, there are patches under the skin, arthritis, sepsis and other symptoms, the mortality rate is as high as 60 %. The mortality of piglets before weaning increases, peaking usually lasts 8 to 12 weeks, and the embryonic period of the virus, mostly died at birth or died several days after birth, the mortality rate is as high as 100%.
Fatty pigs showed mild symptoms after infection. A small number of cases showed cough, and there were transient dark patches on the back, sides, abdomen, and tail of the ears, which were prone to secondary infections and symptoms. Pigs often die from secondary infections of pleurisy, streptococcal disease, and panting. If no secondary infection occurs, growing pigs can recover.
Second, the pig reproductive respiratory and respiratory syndrome syndrome anatomical characteristics of the main eyelid lesions is diffuse pulmonary interstitial lung disease, accompanied by cell infiltration and catarrhal pneumonia, pulmonary edema, in the peritoneal and perirenal fat, mesenteric lymph nodes, Edema occurs in subcutaneous fat and muscles.
Third, the treatment and prevention of respiratory disease and respiratory syndrome in pig reproductive 1. Treatment: high temperature can be used 30% analgin injection 20 ~ 30 ml, dexamethasone 25 mg, penicillin 320 ~ 480 million units, streptomycin 2 Grams, one intramuscular injection, 2 times daily; Metoclopramide 1 mg/kg body weight, Vitamin B 120 ml, 1 intramuscular injection, once daily for the purpose of improving pig disease.
2. In order to maintain the temperature inside the pig house, pigs can be fed in a kingfisher dry-sweeping bed. Because the pig-breeding technology in the fermentation bed breaks down pig manure, it can generate a certain amount of heat, increase the temperature inside the pig house, and reduce the outside world. Temperatures cause pig infections.
3. The most fundamental method is to eliminate sick pigs, poisoned pigs and thoroughly disinfect pig houses. The whole field can be sterilized and cultured in a fermentation bed, which can effectively inhibit the re-growth and development of pathogenic viruses.
