Precautionary measures for asthma in winter and spring
Swine asthma is a common disease in pigs and has high prevalence in winter and spring. The control of this disease is mainly to strengthen the management of feeding, insulation and cold protection, supplemented by vaccine prevention and drug control measures. The pigs did not develop the disease and insisted on self-cultivation and self-cultivation. At the same time, the vaccine was prevented. Pigs may be vaccinated with attenuated porcine asthma, and the response is small after inoculation. The immunity of the disease is mainly based on cellular immunity. The effect of immunization with inactivated attenuated strains of lung is determined, and the immune effects in other areas are indefinite or ineffective. The vaccine is diluted with water and used up within two hours. The needle used to take the vaccine should be changed every time to prevent needle contamination or contamination. From August to October each year, pigs and gilts were injected with a attenuated attenuated piglet vaccine; pigs were first free from 1 week to 2 weeks old, and 2 free from 8 weeks to 11 weeks old. Pigs purchased from abroad may be immediately vaccinated if they have no clinical symptoms. In the unvaccinated pig houses on the outbreak of the disease, emergency prevention can be carried out to reduce the incidence. The immunization period can reach 9 months or more. For the affected pigs and the conditional pig farms, strengthen the daily isolation work so that the sows can be single-circled and the weaned pigs are concentrated and fattened by nest isolation to reduce the number of collaterals. Pigs were reared in isolation, rearing pigs and shelf pigs were housed; pigs and suspicious pigs were removed by various quarantine methods, and the healthy pigs were gradually expanded; and pigs were attenuated by asthma in the outbreaks of the diseased pig farms. Lyophilized vaccine for emergency prevention. Poor farms can be controlled by drugs: During the winter and spring season, when pigs are emaciated and old and weak pigs start coughing and panting, they should add Fengqiang Ganshuangning + Hengfuxing + Linuo and other drugs to the feed of whole group pigs. The therapeutic amount was continuously fed for 3 days to 5 days, and repeated once every 15 days to 20 days. This can not only reduce the incidence but also reduce the impact on the growth of the pigs. 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera v4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera 4g Outdoor Solar Powered 360 Degree Color Night Vision Security Camera Doorbell Camera,360 Degree Camera, Night Vision Security Camera, Security IP Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.szsolarcamera.com
