In winter, maintaining the right temperature is crucial for laying ducks. The ideal temperature range is 14°C to 20°C, and it should never drop below 6°C. Ensuring good insulation and protection from cold is essential during this season. To achieve this, first, make sure doors and windows are closed tightly, and add curtains or blankets to block drafts. Also, keep the area secure to prevent intrusions. Second, lay thick bedding inside the duck house using materials like wheat straw, hay, or rice straw. It’s best to replace the bedding with a fresh layer every night before feeding to maximize warmth. Third, increase the stocking density slightly—around 8 to 9 ducks per square meter—to help them generate body heat. Fourth, ensure proper ventilation by opening doors and windows when ducks are outside grazing, then closing them when they return. This prevents the buildup of harmful gases like ammonia and sulfur dioxide, which can cause illness. Keep the house clean, dry, and warm at all times.
Adjusting the diet is also important during winter. Ducks need more energy to stay warm, so increase the proportion of energy-rich feeds like corn in their diet. Protein levels should remain around 15% to 17%, while adding more green feed such as cabbage or radishes helps meet vitamin needs. If necessary, consider supplementing with multivitamin products to support overall health.
Feeding practices should be carefully managed. Always provide warm food and water, ideally between 30°C and 40°C. Avoid feeding frozen feed or cold water, as this can shock the ducks and lead to unnecessary energy loss. Feed ducks four times a day and always offer clean, warm water. After each feeding, you can give a small amount of green feed to improve digestion. When changing feed formulas, do it gradually to avoid stress and ensure ducks continue to eat properly.
Finally, implement scientific management practices. Winter days are shorter and colder, so try to let ducks out early in the morning and bring them back in the evening. Minimize the time they spend in water and reduce the number of times they go in. Allow them to exercise once a day between 1 and 2 p.m., followed by about an hour of sunbathing. If the weather is extremely cold, it's better to keep them out of the water. However, make sure they have access to water at least once every three days to maintain cleanliness, stimulate blood circulation, and prevent diseases. With these care strategies, ducks can stay healthy and productive throughout the winter.
Anthocyanidins
Anthocyanidins is a kind of water-soluble natural pigments widely existing in plants in nature. They are colored aglycone obtained from the hydrolysis of anthocyanins. Most of the main colorants in fruits, vegetables and flowers are related to them. Under the condition of different PH value of plant cell vacuoles, anthocyanidins make the petals colorful. The main functions about anthocyanidins are antioxidant and free radical scavenging function, nutritional fortifier in food and Natural Pigment.
