1Analysis of the spring and comprehensive prevention and control of common swinePaper Keywords swine; spring; control measures Abstract presented in the spring common swine, including swine fever, swine flu, lung disease, piglet paratyphoid fever, E. coli disease, summed up its integrated control measures for pig farmers for reference. Spring is the season of more than swine and more mixed infections, difficult to cure after the onset of most common with classical swine fever, swine flu, lung disease, piglet paratyphoid fever, E. coli disease. The highest mortality rate of classical swine fever, swine flu mortality rate is low, but can lead to pig growth retardation, decreased the effectiveness of breeding this end, the pig farmers to implement case-based approach, using a variety of preventive measures to control the disease occur, the disease prevention work earnestly to ensure the healthy development of swine industry. I production practice, now common in spring fashion swine control measures described below, for pig farmers 2for reference. 1 swine fever Classical swine fever is also called bad intestinal plague, is caused by the swine fever virus, porcine an acute, febrile, septic diseases. Different species, age, gender, .1-month-old pigs are susceptible to infection within a few pigs disease, 1 month after increasing susceptibility to this disease is highly contagious, when pigs are susceptible to infection, that cause acute outbreaks, the first disease of pigs was the most acute after the death, morbidity and mortality are high mainly reflected a sudden onset, high fever missed, convulsions, twitching limbs, skin and mucous membrane cyanosis. into the CSF before and after the onset of the spring peak, often in disease-prone areas or threatened areas, to the sows in before or after the breeding mating immune l times; piglets in the first 20 to 25 days for free, 50 to 60 days two free in the non-affected areas to deal with breeding sows in each immunization before or after mating 1; species boars in spring and autumn the immune l times; after weaning the immune 1 In addition, you can be ahead of the immune piglets (born after 3intramuscular injection of a copy, 2h after feeding colostrum), can effectively prevent the occurrence of the disease Due to the large temperature difference in spring, should be prepared pig warm, moisture-proof job, regular disinfection, environmental sanitation, strengthen management, improve the pigs disease resistance. pigsty frequently changes within the ground pad, pens around the common ash water , lime, caustic soda water disinfection feed should be diversified, and often feed some carrots, white radish and other succulent green feed. anti-drug prevention and treatment of immune-enhancing intramuscular injection needle, the amount of 0.1mL/kg weight. injection of ice points 5 (the main component of Luo Waer fine), the amount of 0.2mL/kg weight. If respiratory symptoms and bacterial sexually transmitted infection may intramuscular cough mixture Health (the main component of acid, earthworm) better while with the school poisoning (mainly composed of povidone iodine, copper) to the barn every 3d disinfection 1. 2 swine flu Swine influenza is a virus family are 4sticky swine flu virus in pigs caused an acute, highly contagious respiratory disease of clinical disease on in breath, coughing, difficulty breathing, fever, exhaustion, characterized by rapid recovery. Pigs and with swine virus is the main source of infection of this disease, mainly transmitted through the respiratory tract. the incidence of pigs, regardless of breed, sex and age, occurred in the winter and spring, and more endemic in the early spring, often a sudden onset, rapid spread of the swine group, the incidence rate as high as 100%, the incubation period 2 7d, duration of 1 week or so, if the onset period of mismanagement, is prone to bronchitis, pneumonia, pleurisy, etc., to increase pig mortality in this disease is currently no effective vaccine with continuous swine flu vaccine adjuvant inactivated vaccine twice, immune period of up to 8 months. prevention should be strengthened disinfection of barns, pig keeping clean and dry. strengthen management, regular use of 5% caustic soda pig disinfection, in wet weather, when mutated or attention to warm cold, keep the environment stable note barn ventilation, especially in the spring, but Fangzei wind, moisture addition, the onset of the season is not 5the introduction of new pigs from the field, where the introduction of New pig breeding must be isolated until one week after confirmation of disease-free into the original herd. A drug used regularly (the main component of ribavirin) to prevent spices. in the event of swine flu, first supply of nutrient-rich green succulent feed, pigs and timely identification of suspicious pigs, isolation and treatment. piggery disinfected with 2% caustic soda solution, feces accumulation of fer
