Comprehensive matching techniques for safe production of chickens in winter

The work of cold prevention and heat preservation is the most important thing for the safe production of chickens in winter. The main technical links include: increasing the thermal insulation layer of the chicken house, timely adjusting the feeding rate, and paying attention to ventilation. The main technical contents are as follows: 1. Increase the thermal insulation layer of the chicken house. If frosting is found in the roof of the chicken house and the north wall, the hanging shed of the insulation layer should be added, and the insulation layer should be increased with plastic sheeting or linoleum paper to block the north window. Wind barriers can also be set up in the appropriate place where the main wind direction is away from the chicken house to alleviate the cold wind. 2. Adjust the feeding amount timely according to the air temperature. Always pay attention to the weather forecast and add 10-20 grams of feed to each chicken 1-2 days before the cold spell for 3-5 days to maintain body temperature and egg production level. For every 3 ℃ drop in temperature, about 5 grams should be added. After the cold spell passes and the temperature picks up, the original feed quantity will be restored. 3. Pay attention to ventilation. In the cold climate, the relationship between ventilation and warmth should be properly handled, and the feces and sundries in the chicken house should be removed in time to ensure that the air in the chicken house is fresh. When the weather is better at noon, windows should be opened for ventilation, so that the air in the house is fresh and oxygen is sufficient for prevention. 4. Prophylactic administration. The resistance of winter and spring chickens has declined, so special attention should be paid to epidemic prevention and disease prevention. According to the actual situation, we can regularly feed some preventive drugs and appropriately increase the content of vitamins and trace elements in feed to enhance the physique of chickens.
