We must also pay attention to the color and shape of the feces. If chicken spirit, loss of appetite, or fecal abnormalities are found, we should promptly pick out.

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 layer chickens, feeds can be added at night, and it is advisable to feed the chickens before turning off the light.

Reasonably adjust the flock Before the winter, the low-yielding chickens in the old chickens and the thin chickens in the new chickens will be eliminated in time. 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 observe carefully after gregarious, and to stop the fight in time. For hens who have strong fighting desires and hens that have been injured, separate cages should be taken out. support. 4. Do a good job of environmental disinfection Autumn season has low temperature and humidity, which is very suitable for the survival of pathogenic bacteria.

The closed chicken house must still be sterilized with chicken air once a week. The virus can be sprayed with 100 poisons. The external environment can be sterilized with 10 to 20% lime water, or 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. 5. Blocked vaccination loopholes In autumn and winter, 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 based on the actual situation of the local epidemic, and replant vaccines in a timely manner in order to block the vaccination loopholes and ensure the safety of chickens in winter.
