First, cold and warm. The effect of low temperature on laying hens is very obvious. In winter, the breeding density can be appropriately increased, doors and windows can be closed, straw canopies can be added, warm water can be served, and stove warmers can be used to keep warm and keep warm so that the temperature of chicken houses can be maintained at a minimum of 3°C-5°C. between. Second, moderate ventilation. When the air in the house is dirty, it is easy to induce diseases such as the respiratory tract of chickens. Therefore, it is necessary to remove the feces and debris in the house in winter. When the weather is good at noon, the windows are opened for ventilation, so that the air in the house is fresh and the oxygen is sufficient. Third, reduce the humidity. The hot air in the winter house comes into contact with the cold roof and the walls will condense into a lot of water droplets, causing the house to be overly moist, creating the conditions for large numbers of bacteria and parasites. Therefore, we must pay attention to keeping the house clean and dry, it is strictly forbidden to splash water on the floor of the house. Fourth, regular disinfection. Resistance to chicken body in winter is generally weakened. If neglected disinfection, it can easily lead to disease outbreaks. Winter chickens use water disinfection methods, that is, by adding disinfectants (such as 100 toxins, strong disinfectants, sodium hypochlorite, and Weidao disinfectants) in drinking water, and once a week. The ground of the house can be disinfected with dry powder disinfectants such as white lime and powerful disinfectant, which is suitable for 1-2 times a week. Fifth, add light. The total daylight for winter chickens should not be less than 14 hours or 17 hours. The supplemental lighting is divided into two ways: fill light and segment fill light. A fill light is to make up the required light at one time in the morning before the morning light or in the dark at night; the insufficient light time for subsection light fill is divided into two supplies in the morning and the evening. Six, reduce stress. Chickens are small and frightened. Therefore, there must be a certain amount of time and order for the feeding of chickens, adding water, quail eggs, disinfecting, cleaning, and excreta removal. The movement during the work should be gentle, and strangers and other animals are strictly prohibited from entering the house. If there are strong noises from the outside world, such as the sound of firecrackers at the festival, harsh gongs and drums, etc., the keeper must enter the hen house in time to create a sense of security that the “owner is in the bodyâ€. It is also possible to add appropriate amounts of multivitamins or anti-stress drugs to the feed or drinking water to prevent and reduce the loss caused by stress response. Seven, increase energy. Chicken feed on the body to obtain heat to maintain body temperature. The lower the ambient temperature, the more calories the chicken uses to protect against the cold. In order to meet the physiology and production needs of chickens, it is necessary to ensure sufficient energy in the feed for winter chickens, in addition to guaranteeing a certain percentage of protein, to increase the amount of high-energy feed containing starch and sugars. Eight, enhance physical fitness. The resistance of chickens in winter is declining. Special attention must be paid to epidemic prevention and regular vaccination. Can also be regularly fed some preventive drugs, appropriate increase in the content of vitamins and trace elements in feed, avoid feeding moldy feed, sewage and cold water mixed with ice and snow. Nine, to prevent the thief wind. The cold wind that blows in from the cracks in windows and doors and in the walls is called a thief, and it is easy for chickens to catch a cold. Therefore, the doors and windows must be closed in time to block the wall holes and crevices. X. Eliminate predators. Winter rats, weasels and other animals often gather in the shed to steal food, bite bad utensils, even spread the disease, bite, kill chickens, or cause chickens to respond to stress, so we must make every effort to destroy the enemy.
