After the laying hens are laid, the egg production rate gradually rises, and it is about 25-44 weeks old at the peak of egg production. During this period, in addition to providing adequate protein feed, proper control of energy feed and scientific and reasonable calcium supplementation, creating a safe and comfortable environment for chickens is the key to prolonging the peak period of laying hens and improving the efficiency of raising chickens. 1. Ventilation: Regardless of the size of the chicken house or the number of chickens, it is indispensable to keep the air in the house fresh and well ventilated. Especially in high-density rearing henhouses, the house has poor ventilation, oxygen, hydrogen sulfide, sulfur dioxide, etc. The accumulation of harmful gases can induce a variety of diseases and directly affect the production of eggs. In the production, the ground window is set at the bottom of the chicken house, the middle window is set, and the exhaust cylinder with cap is arranged on the roof. All summers are open. In the winter, the central window can be closed. Only partial windows and exhaust cylinders on the roof can be opened. Exhaust fans can also be set in the middle to quickly discharge foul air in the winter. In addition, pay close attention to the ventilation system during the winter and do not cause sleaze or reduce the temperature inside the house too low. 2. Illumination: layer chickens start from 20 weeks of age, add 0.5 hours of light per week until reaching 16 hours per day, then maintain 16 hours of light every day, and gradually increase to 17 hours until the laying hens are eliminated 4 weeks before they are eliminated. . Artificial light supplements work best every morning before dawn. When supplementing light, the floor is preferably 3-5 watts per square meter. The bulb is about 2 meters from the ground and the distance between the lights is 3 meters to ensure uniform lighting throughout the house. 3. Temperature: The most suitable temperature for laying hens is 13-23°C, which is not conducive to laying eggs. In summer, pay attention to the ventilation of the coop, increase the power of the ventilation fan, change the horizontal ventilation to vertical ventilation, combine water spraying and watering, and appropriately reduce the rearing density to reduce the temperature. In winter, large furnaces can be produced to heat and heat, but to prevent gas poisoning and smoke and dust pollution. 4. Humidity: The suitable humidity for laying hens is around 60-70%. If the humidity is too low, the feathers of the chicken are disordered, the skin is dry, the feathers, fleas and claws are dull, and it is easy to cause dehydration of the chicken body and a variety of respiratory diseases. If the humidity is too high, the chicken body will be contaminated and the bacteria will multiply. Easy to cause a variety of diseases, so that the egg production decreased. Therefore, in the production can be combined with spray to increase the humidity within the house and reduce dust pollution; by strengthening the ventilation, or release moisture from the chicken house to remove moisture. 5, drinking water: water is very important to the production of layer chickens, the consequences of water shortage is often more serious than the lack of material, inadequate drinking water can reduce egg production by 2%. During the peak period of egg production, sufficient clean drinking water meeting drinking water standards should be provided. 6. Stress: Layer chickens have high production intensity at the peak of egg production, heavy physiological burden, poor resistance, and sensitivity to stress. The direct increase in feed consumption has led to a sharp drop in egg production and it is difficult to return to the original level. Therefore, to keep the sheds and the surrounding environment quiet, keepers should wear fixed work clothes, and no casual workers should enter the henhouse; plug the rat's rathole and periodically kill poisoned rods outside the house; put doors and windows, ventilation nets, Barbed wire is sealed to prevent cats, dogs, birds, and rats from entering the coop. Fireworks and firecrackers are prohibited from being placed around the coop. Feed processing and loading and unloading should be kept away from the coop to prevent noise stress. 7, quail eggs: timely quail eggs, create an egg-free environment, you can increase chicken egg production rate. The peak of chicken egg production is generally 3-4 hours after sunrise, and the afternoon egg production only accounts for 20% of the whole day. Depending on the time of laying and the amount of eggs produced, quail eggs are used 2-3 times a day.
