The summer temperature is relatively high, and then the egg production will drop, and even the egg production will stop. It is a natural phenomenon that some chicken farmers think that this is a natural phenomenon. In fact, as long as artificially improving the feeding and management conditions of laying hens and creating a suitable environment, then the chickens can be kept in the summer. Produce eggs in chicken battery cages.
Ventilation and cooling The closed house can be equipped with a fan or a ceiling fan. The longitudinal ventilation is better than the horizontal ventilation. The wind speed in the summer house is preferably 1.0 m / s to 1.2 m / s. Wet curtain is the most economical and effective cooling measure for large-scale production. Longitudinal ventilation combined with wet curtain cooling to prevent heat stress is better. An open chicken house can be fitted with a fan that opens all doors and windows to promote
Into the air circulation.The best way to relieve the heat stress of laying hens is to spray water. When the temperature exceeds 32 °C, a high-pressure rotary sprayer can be used to spray cold water on the top of the house or to cool the chicken by cold water spray. Reduce the temperature by 5 ° C ~ 10 ° C.
Reduce the stocking density and remove chicken manure in time. Summer chicken manure is easily fermented and induces respiratory diseases. Therefore, the feces and litter in the house should be cleaned up in time to keep the house clean, dry and hygienic.
Change the feeding management schedule In the hot season, you should take the light method of turning on the light early and turning off the light early, that is, turn on the light from 3 to 4 in the morning, turn off the light from 7 to 8 in the evening, and increase the feeding or even before the temperature rises in the morning. The number of feeds allows the chicken to eat at the coolest time of the day. At the same time, try to reduce the activity of the chicken, stop feeding at 1 to 3 o'clock in the hottest afternoon, to reduce the harvest of the chicken.
Supply fresh, clean and cool water throughout the day. In high temperature, the amount of water in the laying hens is about 3 to 4 times that of the feed intake. It is necessary to ensure that the chickens can drink clean, non-polluting cold water throughout the day. Do a good job in disease prevention
