When winter falls and the weather is cold, people will keep warm and keep warm to prevent cold. Of course, chickens cannot be used as exceptions. Farmers who raise laying hens should pay attention to the breeding of laying hens in winter, and the farmers should keep warm from temperature, feed, light and ventilation. Five ways to control the disease and control the disease.

1. Temperature: Generally speaking, the optimum room temperature for laying hens is 18°C~24°C. When the temperature is lower than 5°C, the egg production rate decreases. When the temperature is lower than 0°C, the egg production is significantly reduced, and the feed consumption is obviously Adding causes the ratio of the egg to rise. Therefore, in the winter, it is necessary to adopt a cold and warm method to maintain the temperature inside the house within an appropriate range.

2, feed: 1 progress energy level: winter temperature is low, chicken body heat consumption is large, the energy to maintain body temperature demand increases, in order to satisfy the chicken body’s own consumption and egg production needs, must add the energy content of the guess to make it reach 11.72 ~ At 12.35 MJ/kg, the protein is maintained at 15% to 17% and the calcium content is maintained at 3.4% to 4.1%. 2 Adjust the feeding time: Feed the chicken as soon as possible after turning on the light in the morning, feed the chicken before turning off the light at night, shorten the fasting moment of the laying hen cold night, and relieve the cold stress.

3. Illumination: Illumination has a promoting effect on ovulation and laying of laying hens. It takes 16 hours of light per day. In winter, the natural light is shorter than 12 hours, and artificial light is required. The method is: hang a 5 watt energy-saving lamp in the chicken house, the lamp is 2 meters away from the ground, and the lamp is about 3 meters between the lamp and the lamp. Once the moment of light is compensated, it is necessary to turn on and off the lights on time, and persevere, and must not be interrupted, suddenly.

4, ventilation and ventilation: winter closed chicken house will produce a lot of harmful gases, such as ammonia, carbon dioxide, hydrogen sulfide, etc., have a strong impact on chickens, and even induce chronic respiratory diseases, so, under the premise of heat preservation should pay attention to ventilation. In cold weather, you can open the ventilation window or the ventilation fan to change the air when it is warm at noon. The sunny day is usually between 10 am and 2 pm. The length of ventilation and ventilation, and the size of the ventilation window should be determined according to the density of the flock, the temperature inside the house, the weather conditions, and the degree of harmful gas.

5, do a good job of induction of disease prevention: do a good job of disinfection, regular disinfection of the chicken house table, sink, trough, utensils, etc. Disinfectants should use broad-spectrum, high-efficiency, non-toxic, non-side-effect and highly adhesive drugs, such as chlorpyrifos. It is necessary to select three or more different types of disinfectant cross-rotation to prevent drug resistance. Generally, it is disinfected in the middle and afternoon when the temperature is high. It is disinfected once a week under normal conditions. If the chicken is infected with infectious diseases, the temperature inside the house is low, and the dust is more than 2-3 times a week, together, the drug concentration can be Decrease by 10-20%.
