After the fall, adult hens cease moulting. Fresh hens in spring breed eggs one after another. However, in autumn, the weather is variable and there is a large temperature difference between day and night. When the “sensitive” season meets with “sensitive” day-old chickens, the disease easily occurs. . Recently, the reporter interviewed members of the expert advisory group of the newspaper and experts of the College of Veterinary Medicine of the Northwest Agriculture and Forestry University, Wang Jingyu, on the precautions of raising chickens in the autumn. Wang Jingxuan said that feeding and management should be strengthened according to the climate change in the autumn and the status of the flock in order to improve the breeding efficiency.

Especially after the fall, the temperature gradually decreases and the temperature difference between day and night is relatively large. Farmers should pay attention to the relationship between heat preservation and ventilation. Make sure that the house's small climate is relatively stable. In particular, the weather in the early fall season is still rather hot, and with more rain, the house is relatively humid and, if necessary, ventilation and ventilation are strengthened. Open doors and windows during the day, increase ventilation, and provide adequate ventilation at night. Ventilate and ventilate air under the condition of ensuring the temperature of chicken house, and avoid respiratory diseases caused by temperature stress and poor ventilation.

The general ground free-range density is 30 to 25 per square meter from 1 to 20 days, and 20 to 15 per square meter at 21 to 40 days. Depending on the age of the house, the size of the house can be grouped in a timely manner.
