First, make preparations for cold protection. Regardless of the size of the chicken farm, before the arrival of winter, conduct a comprehensive inspection and maintenance of the chicken house, block the cracks in the walls, replace the door and window glass, and prepare the films and straw curtains for winter use. Semi-open sheds should be demolished in time for the pergola, and the back windows can be closed with plastic sheets. At the same time, the preparation and installation of heating facilities must also be well done. In particular, chicken farms that use coal-fired boilers for heating must check the flue and chimneys. When leaks or leaks are discovered, they can be plugged, replaced, or reformed as soon as possible.

Second, pay attention to day-to-day management Every day feeding, feeding, picking eggs, we must carefully observe the flock of the demeanor, appetite and desire to drink, but also pay attention to check the color and shape of the feces, if found chicken insomnia, loss of appetite or fecal abnormalities Should be singled out in time for further inspection and treatment. In the seasonal changing season, the chicken nerve is very sensitive, and it is prone to adverse stress reaction to external stimuli. Therefore, when feeding, feeding water, picking eggs, and sanitizing, the actions should be as slow as possible to prevent the occurrence of adverse stress reaction and lead to discontinued production. Or induce disease. For grass-raised chickens that are housed outside the home, chickens should be rushed into the house at night when the temperature is low. Pay attention to watching and listening to the weather forecast and do a good job of keeping warm and cold in advance.

In order to promote the feeding of laying hens, feed can be added at night, and it is advisable to eat chickens before turning off the lights. Feed replacement should be gradual, with a period of 2 to 3 weeks of adaptation to prevent sudden changes in the stress response.

Third, reasonable adjustments to the chickens before the winter, the timely elimination of old chickens in the low-yield chickens and thin chickens in the new chickens. For old chickens without artificial forced moulting, the hens that have finished moulting should be separated to form a new group, focusing on preserving hens with bright red crowns, large pubic bone spacing, loose and loose anus, and soft and elastic abdomen. However, when raising groups of chickens in the process of group adjustment, putting new chickens will destroy the original stability pattern, often fighting to re-establish the group order, before the determination of the affiliation relationship, there will be a fight phenomenon, so when you adjust the flock to control The number of good groups is generally 100 to 200. It is advisable to have a careful observation after the gregarious group to stop the fight in time. For hens who have a strong desire to fight and hens that have been injured, separate cages should be taken out. support.

Fourth, do a good job in environmental disinfection Autumn, autumn, low temperature, humidity is very suitable for the survival of bacteria, and autumn and winter is still a popular season of many infectious diseases, therefore, environmental disinfection, utensils disinfection, drinking water disinfection is also very important. Closed-type chicken houses still need to be sterilized once a week with chickens. They can be sprayed with 100 toxins. They can be sterilized with 10% to 20% lime water, or sprayed with 3% to 4% caustic soda. In the sheds, feeders, buckets, buckets, drinking fountains, and other utensils can be sterilized with 0.01% bactericidal toxin or 100 toxin or chlorine. Vehicles, brooms, shovels, and other equipment used to clean feces should also be regularly cleaned and disinfected. Bacteria poisonous net and 100 poisonous to kill in eggs and meat have no residue, can be used for disinfection of drinking water, but the implementation of drinking water disinfection, the drug concentration must be accurately formulated in accordance with the provisions, can not have the slightest ambiguity.

V. Blocking the epidemic vulnerabilities In autumn and winter seasons, poultry are prone to various diseases such as Newcastle disease, highly pathogenic avian influenza, fowl cholera, infectious rhinitis, infectious bronchitis, infectious laryngotracheitis, and pox disease.

The main principle of disease prevention is to do a good job of environmental disinfection and early immunization. We must carefully examine and analyze the immunization schedules, immunization records, and routine immunization programs for chickens in autumn and winter. Chickens, unvaccinated chickens, and poorly immunized chickens should be replanted in a timely manner according to the local epidemic situation in order to block the vaccination loopholes and ensure the safety and health of the flock.
