In early spring, the air is cold, and the temperature difference between day and night is relatively large. The flock is affected by changes in the external environment, often causing the AAT龌龊W to decline or sudden epidemic. In order to prolong the peak period of egg production, it is necessary to strengthen the coops and flock management to the flock. Provide a suitable egg production environment, so that the stable production of high-yield chickens.
1, keep warm
The egg laying temperature range is 10°C~28°C, and the optimum temperature is 13°C~21°C. If the temperature is too high or too low, the egg production rate will be affected. Each increase or decrease will cause the laying rate to decrease by 0.3. %. In early spring, the temperature in the chicken house will decrease as the ambient temperature decreases. Attention should be paid to improving the temperature of the chicken house and adopting insulation measures. It is possible to heat the room indoors or use a hot air heater, and block the windows on the back of the house to keep the house temperature no lower than 8°C.
2, ventilation
Due to the early spring cold, the house is closed tightly, and a large amount of harmful gases such as carbon dioxide, ammonia, hydrogen sulfide, etc. are produced in the house. If it is not discharged in time, the most likely cause is the occurrence of chronic call, transmission, rhinitis and other diseases in the flock. . Therefore, ventilation and ventilation should be carried out every day under the condition of maintaining temperature, or exhaust fans should be installed in the house to eliminate harmful gas inside the house. However, attention should be paid to preventing thieves from invading the flock.
3, add lighting
Illumination is one of the important factors affecting the AAT龌龊W of laying hens. It plays a decisive role in sexual maturation, ovulation and laying of chickens; generally requires that the light is maintained at 16 hours per day during the laying period, and lighting can be provided after 60 weeks of age. Increased to 17 hours; especially in the fog when the light is dark, affecting the chickens to eat, so in the dark fog when the light is dark, turn on the lights in time to supplement the light, but also pay attention to often wipe the bulb to prevent dust on the bulb Too thick to weaken light intensity.
4, feed level
In early spring, the temperature is low, and the chicken's internal body maintains increased energy. Therefore, it is necessary to appropriately improve the energy content in feeding and guessing, and an appropriate 2% increase in corn or 0.2% of animal and vegetable fats and oils can be used to improve energy supply.
5, adjust the flock
After the chickens begin to lay eggs, they need to pay attention to seeing the chickens at any time. If chickens have atrophy, weight loss and poor spirits are fed alone or eliminated, they can save the feed and increase the egg production rate. Spread of the disease, reduce the number of medications, thereby improving economic efficiency.
