With the arrival of autumn, the changeable climate, cooler weather and migration of migratory birds, the high incidence of infectious diseases in chickens is about to enter, and chickens are susceptible to diseases caused by cold stress and migratory birds.
Daily poultry inspections help to identify problems in the chicken coop environment and improve management in time to cope with the changing autumn.
The weather gradually turns cooler in autumn, the climate is changeable, rainfall decreases, according to the climate characteristics, the main point of chicken health care is based on the “prevention is more important than cure” policy, to improve the work of autumn prevention, remind the majority of farmers pay attention to the details of chicken.
The impact of environmental changes on the chicken epidemic
1.the temperature difference becomes larger, the morning and evening become cooler. In general, the weather in September cooled down, so that the chicken group quality has some recovery and adjustment . However, as the temperature difference between morning and evening continues to increase, and the weather turns cooler, it will provide favorable conditions for the prevalence of viral diseases and respiratory diseases.
2.the climate is dry, the chicken coop dust increased, the chicken respiratory mucosa is prone to dry cracking damage, the air suspended with pathogenic microorganisms of dust, easy through the damage of the respiratory mucosa infection, induced respiratory disease, especially the poor environment of the chicken coop, prone to Escherichia coli and Mycoplasma fowl venomous mixed infection.
3.the night mosquitoes increased. September mosquitoes are still more, some mosquito-induced diseases, such as chicken pox and white crown disease incidence gradually increased, especially skin-type chicken pox-based mosquito disease will occur in poor management conditions and no anti-mosquito measures in the chicken farm epidemic.
From autumn, chicken farming has entered the stage of careful management, the majority of farmers should fully consider the structure of the shed, internal hardware and other conditions, and then decide on the chicken density, on the chicken time, sub-transfer group governance, insulation, ventilation and specific manipulation implementation methods and other details.
The focus should also be on the prevention and control of the following diseases.
1.to improve the prevention and control of respiratory diseases, most of them are due to the neglect of the temperature difference between day and night, not to provide star service to the chicken.
2.The frequency of cold stress disease caused by the big temperature difference between day and night increased, mainly kidney transmission and bursal, characterized by a close relationship with the rain and cooling at night, the onset of the disease is more urgent, but a lot of misdiagnosis and mistreatment.
3. due to the density of the flock is large, the need for insulation at night, closed chicken house caused by poor ventilation and more frequent E. coli and mycoplasma mixed sense.
4. Influenza and E. coli, mycoplasma mixed infection began to occur epidemic.
5.chicken pox also began to appear serious cases, mostly due to neglect of inoculation. To do a good job of chicken pox prevention and control measures.
6.the prevention of chicken “low temperature disease”. High summer temperatures, chicken respiration to strengthen the body easily caused by the loss of HCO3-, resulting in chicken calcium, phosphorus and other minerals metabolism absorption is reduced, causing abnormal growth of bone tissue.
In addition, you need to pay attention to several points:
1. The natural light time in this period is in a trend of gradual shortening, which is not conducive to the egg production of chickens.
For chicken houses that use a combination of natural and artificial lighting, attention must be paid to the time when the lights are turned on and off to ensure that the daily light hours are stable.
2. Do a good job in feed management. Pay attention to temperature and humidity during the alternating seasons to prevent feed from becoming moldy and ensure that the chickens eat the feed in the trough clean once a day to prevent the feed from deteriorating at the bottom of the trough.
During the alternating summer and autumn seasons, the chicken coop is often in high temperature and high humidity, which can easily cause moldy items. If too much feed is added to the trough, the remaining feed at the bottom of the trough for too long is likely to lead to moldy feed deterioration.
3, pay attention to the use of new corn, usually autumn came on the market will appear a large number of new corn, new corn moisture content is high to a certain extent diluted the nutrition of corn, with the rise in moisture content of crude protein significantly reduced, so to accurately adjust the feed ration in a timely manner.
At the same time, the high moisture content of corn need to pay more attention to the storage of corn, good anti-mold measures.
