To ensure that the hens do not stop production in winter, they must adopt effective feeding and management measures to meet the requirements of laying hens on temperature, light, and nutrition.
Cold insulation
The most suitable living temperature for laying hens is 18°C. In winter, the temperature of the chicken house should be maintained at more than 10°C. In general, a windbreak is installed around the house, and plastic sheets are put on the doors and windows to block the leaks in the walls and prevent the hen's wind from entering the thief.
Increase lighting
Illumination can not only enhance the hen's constitution, but also promote the secretion of pituitary hormones in hens, so that the hens' egg production activity is vigorous. Therefore, due to the shortened winter time, artificial light should be added to stimulate egg production. Usually, electric lights are installed in the house to allow the hen to get 15 hours of light; morning and night lights can also be used to make the layer longer in winter than in summer and autumn. 0.5 to 1 hour.
Increase the number of feedings
In winter, when the temperature is low, layer chickens must eat enough nutrients from the feed to withstand the cold to ensure their high yield performance. The number of feedings can be increased to encourage the layers to feed more.
Increase nutrition
In winter cold, the layer itself consumes more energy and needs to feed from the feed. Therefore, in the winter, the energy level in the layer feed should be increased to 0.12 megajoules per kilogram. In addition, the appropriate increase in the amount of vitamins in the feed in the winter can increase egg production in laying hens. According to the experiment, the double amount of vitamin A and D3 in the feed during the winter can increase the egg production rate by more than 3.5%.
Strengthen disease prevention and treatment
Winter is the season of respiratory infections in chickens. Once a condition is discovered, it should be promptly prevented by appropriate drugs. At the same time, it can be sterilized once every 5 to 7 days with 100 toxin disinfectants.
