How to raise hens' egg production rate in winter
How to raise the hen's egg production rate in winter to maintain the temperature: The optimum temperature for laying hens is 18°C. Usually at 16 °C -21 °C, laying hens have a higher rate of egg production. When the temperature is lower than 5°C, the egg production rate decreases; when it is lower than 0°C, it decreases significantly; when it is lower than 10°C, it stops production. If the temperature is too low, it will increase the consumption of feed. Therefore, the appropriate temperature is the key to improving the hen's winter egg production rate. At present, the usual adoption is to raise 10 chickens per square meter. In the sheltered area of ​​the sun, take a heat insulation nest, build a double sandwich wall, fill dry stuff like sawdust or livestock manure, grass ash and other materials in the middle. The wall is low in the north and south, and the roof of the nest is 45 sloping. Cover the plastic sheet and cover the straw at night. The temperature in the nest is kept above 5°C. At noon when there is not enough wind and light, ventilation is carried out, and the hens are driven out of the house for 1-2 hours and cleaned at the same time to reduce the temperature. In general, the chicken house should be covered with thick grass curtains at the entrance of the window, and the doors and windows should be opened before the chickens are placed in the daytime. When the temperature inside the house is adapted to the outside temperature, the chickens are put again. In general, a thick litter can be used for the insulation of the chicken house. Pads are often used for rice husks, comminuted grass, sawdust, shavings, etc. The thickness of the paving is preferably 10 cm. It is gradually added, and is removed after the spring of the second year. Supplemental lighting: light is suitable for 15 hours, up to no more than 16 hours. The way to supplement the light in winter is to install electric lights in the chicken house. Generally, a 15 watt bulb can be installed in the heat insulation nest. You can turn on the lights two times sooner or later, starting at 5 o'clock every morning until dawn, and turning on the lights at 20 o'clock in the evening. Strengthen nutrition: In winter, layer chickens are fed with compound feeds with higher heat energy, and they can be fed 4 times a day. Sand traps and shell tanks are set inside the chickens, allowing any chickens to eat freely. Allow chicken to drink warm water when conditions permit. Strengthen epidemic prevention: In the winter, the main focus is on the prevention of infectious diseases, such as chicken gizzards, fowl cholera, chicken pox and other diseases, and the chicken house is regularly sterilized.
