In the winter and spring season, you need a vigilance of chicken disease – bird illness prevention and control – China Animal Husbandry Website – A useful animal husbandry website

In the winter and spring, the climate change is frequent, and the chickens are prone to disease due to changes in external factors. It is to know that when the chicken farm has a disease, it will form a wide range of communication, which has a great impact on farming work. Therefore, we should pay attention to the diagnosis and treatment of chicken disease, and improve the safety of breeding. Today, I discussed the diagnosis and treatment of five common chicken diseases in the season season, I hope to help everyone. 1. Avian influenza influenza is a continuous harmful infectious disease in recent years. This disease will appear in the four seasons of the year, especially in the winter and spring season. Avian flu is mainly caused by viruses, and the general non-pathogenic avian influenza virus can produce certain antibodies in the boulder body. Low pathogenic avian influenza viruses can produce some discomfort in the chicken body, resulting in a decline in eggs in the egg hns, and the mortality rate increases. At this time, the antibody of chicken itself will not play too much; highly pathogenic poultry The influenza virus is more harmful and can cause a chicken death in a short time, and a very large loss of breeding work. Chickens have different symptoms due to different degrees of virus, but most of them have problems, face edema, chicken black, organ and muscle function, digestive tract, respiratory hemorrhage. 2, new city disease new city evolution is a common chicken disease, which will appear in the chicken group in each age group, and its infectious sources are sick chops, and the drain of the disease will affect healthy chicken. The new city duel will endanger the digestive tract and respiratory tract of the chicken body. Over time, the function is gradually declined until death. This disease is high in winter and spring season. After this disease occurs, it will cause a wide range of diffusion, which has increased the difficulty of farming, which is the most embatful new market disease is the largest (directly died), and the harm of chronic new city disease is small (the function declines, the amount of energy, the reduction of egg production, etc.) However, it also needs to be paid to avoid affecting benefits. At present, the best way to respond to new city is to immunize chickens, improve the immunity of chickens, and related farmers should use the correct vaccine to use the correct vaccine to achieve the expected prevention effect. At the same time, it is necessary to pay attention to the vaccine preservation work, according to the preservation of the vaccine, to prevent incorrect storage methods to lose the vaccine, affect the immune effect. During the inoculation, the vaccine drops into the nasal cavity and eyes of chicken, which is the best inoculation method that enables the vaccine to be sufficiently absorbed, or the vaccine is added to the water, butDo not add a disinfectant in the water; or add the vaccine into the sprayer to spray, so that the spray is full of chicken farms. Before and after vaccination, the chicken group should not be carried out, otherwise the immune effect will decrease, while monitoring the effect of the immunity, when an abnormal situation occurs, it is necessary to solve it in time. Taking into account the actual situation in breeding and the current market against antibiotics, it is best to use some micro-generated fermentation products similar to nuclear honesty and new city dual-resistance in treatment and prevention. The dependence on the dependence of antibiotics and the problem of drug disability during the breeding process. 3, chicken respiratory diseases typically cause respiratory problems when there is infectious disease, which is the problem that should be paid attention to. In the winter and spring season, the climate change is frequent, and the probability of chicken respiratory sickness will increase. Therefore, in the breeding process, pay attention to avoiding respiratory diseases in the raw group, prevention and treatment through reasonable measures. Disinfection: In the course of breeding, the breeding site should be disinfected, disinfected with disinfectants, feeding, tools and other disinfectants, once a day, 7 days for 7 days, reduce the number of bacteria; insulation and ventilation: general in winter In the spring season, in order to maintain the temperature of the farm, the farm will not take ventilation homework. In fact, this practice is very incorrect, because with the increase in temperature, the activity of the pathogen will increase, but the chicken will have a negative impact Therefore, we must do a good job of ventilation work while doing a good job of holding, while reasonably controlling the number of chickens, avoiding excessive density, safeguarding breeding work; doing a good job in vaccination: Immunojection for chickens in time Increase the safety of breeding, the excrement of chickens should be removed in time to reduce the possibility of pathogenic propagation. Drug prevention work can not be dropped: in terms of drug prevention, it is not only to take into account the cost of breeding, but also the pharmacodynamic, drug disabled problem, and choose a microecological preparation similar to anti-Shuchi. It can often achieve the effect of half the power, which greatly reduces the probability of the disease on the disease. 4, chicken E. coli disease is mainly caused by E. coli, which is also a common chicken disease. It will cause problems in the digestive tract of chicken, and the growth efficiency of chickens is lowered. There will be a large-scale disease situation, affect the economic interests of the entire farm. This disease will appear in any age of chickens, so it is necessary to attract enough attention. E. coli can be in the outside worldUnder the stimulation of factors, to this end, try to minimize the external stimulus, so that E. coli is constrained, the best way is to do hygiene and disinfection work, and strengthen vaccination work and improve the safety of breeding. 5, broiler ascites syndrome, broiler, the growth rate of broilers is faster, if the ventilation work of the farm is not good, or the density of the farming is too large, it will make the chicken group appear as ascending syndrome, bring a large negative impact . In order to effectively prevent, we should do a good job of ventilation, reduce the number of pathogens, while doing a good job of heat preservation, avoiding cold problems in the flock; second, to control the growth rate of chickens, avoiding too fast growth, to reduce fine feed The quantity, adding crude feed to lower the probability of appearance of ascites syndrome. In short, in the winter and spring season, the probability of disease occurs is high, and the breeding staff should strengthen disease prevention and treatment, and do scientific management, do a good job of ventilation and heat preservation, and the temperature cannot be too low, but also do Good immunization work, properly improve the immunity of the chicken, and choose the appropriate drug to prevent it. At the same time, in the breeding process, pay attention to the environment clean, strengthen nutrient supply, prevent disease from spread over a larger range, and reduce the loss to the lowest level.
