Do hens lay fewer eggs in summer?

In summer, the temperature is high, and chickens have no sweat glands, so they can't radiate body heat with sweat glands, so they can only radiate heat by opening their mouths and breathing faster. Therefore, in summer, many hens lay fewer eggs.

According to scientific detection, the most suitable environmental temperature for laying hens is 13~2℃. If it exceeds 21℃, the appetite will decrease, the eggshell will become thinner, the protein will become thinner, and the egg weight will become lighter. If it exceeds 29℃, the laying will be obviously reduced, or even no eggs will be laid.

How to make hens lay more eggs in summer

First, reduce the ambient temperature

More trees should be planted around the henhouse, and cold water should be sprayed in the henhouse or at the air inlet.

2. Adjusting feed energy and increasing protein content can increase 3% bean cake and 2% fish meal in feed. The more practical feed formula is: corn flour accounts for 3%, bran accounts for 5% and bean cake accounts for 2%.

Third, change the lighting system to improve the feed intake of chickens. If free-range chickens or open chicken coops are used, sufficient feed should be ensured in the morning and evening. If closed chicken coops should use intermittent lighting, it is best to turn off the lights at 3 noon every day, or still light during the day, and turn on the lights at 1-2 o'clock in the evening to feed for one hour.

Fourth, provide enough drinking water. The water consumption of a chicken is 91-325ml, and the water consumption in summer is about 4 times that in winter and 3.5 times that in feed intake.

5. Strengthen ventilation and keep the air fresh. In summer, attention should be paid to opening doors and windows day and night for ventilation, but screen doors and screens should be closed to prevent mosquitoes and flies from entering the house. If the henhouse is above 25℃, a fan can be used for ventilation day and night. In summer, all fans should be fully on during the feeding time.

6. Reduce stress factors and keep the chickens quiet. You should refuse to visit, pay attention to prevent cats, dogs and other animals from entering the henhouse and keep the chickens quiet. The implementation of feeding operation rules can train the adaptability of chickens to normal feeding management, reduce stress factors and improve the egg production of chickens.

VII. Pay attention to regular and thorough disinfection of chicken coops, feeding troughs, drinking fountains and various utensils

VIII. Feed the chickens with proper amount of baking soda. The temperature is about 26℃, and the feeding amount of baking soda (NaHCO3) accounts for .1%-.33% of the total feed. In this period, pay attention to reducing the amount of salt, and feed baking soda on the spot.

9. Don't feed rancid feed, and feed green feed with appropriate amount of garlic and pepper or dandelion and endive.

ten, the density should be appropriate. If thick bedding is used for flat cultivation, the density is 5.4-6.2/m2; If caged, the density should be 14-15/m2.

Xi. Strengthening epidemic prevention and disease eradication.
