To ensure the well-being and productivity of dairy cows during cold seasons, several key measures should be implemented. First, construct a warm shelter by building an anterior wall approximately 2 meters high in front of the existing cowshed. Install a weatherproof door about 2 meters wide in the center to allow easy access for the cows. The gables should be integrated with the front wall. Place bamboo rafters with a diameter of 8–10 cm between the house and the front wall, spaced 70–80 cm apart. Cover these rafters with wide plastic film and secure it properly. After rain or snow, remove the plastic promptly to avoid damage. On both sides of the gables, leave 2–3 air intake holes measuring around 30 cm square. At the highest point of the shed, install 2–3 round vent holes with wind direction caps, each twice the diameter of the air intakes, to improve ventilation. The greenhouse area should be at least 5–6 square meters per cow, adjustable based on actual conditions.
Second, provide timely shelter. The ideal temperature for optimal dairy production is around 10°C. A warm greenhouse can maintain a temperature about 10°C higher than the outside. When outdoor temperatures drop below zero at night, cows should be moved into the greenhouse for feeding. During the day, when the outside temperature rises, they can be taken out. Before letting the cows exit in the morning, open the air intake holes 30–60 minutes in advance to equalize the indoor and outdoor temperatures. Clean the shed 2–3 times daily, removing urine and manure, and dry the area as needed. In the afternoon, when there is ample sunlight, close the cold doors and air intakes to retain warmth.
Third, feed warm materials. During winter, avoid feeding frozen fodder or water. Provide warm water and feed at a temperature no lower than 15°C, preferably using fresh well water. To encourage water consumption, prepare porridge-like concentrates at around 30°C. Monitor silage moisture and protect it from freezing, reducing feed amounts if necessary. Increase the supply of quality hay, ensuring each cow receives at least 3–5 kg per day.
Fourth, manage breeding effectively. The general rule is to breed cows in spring for summer calving and in autumn for winter calving. Ensure proper timing for winter breeding by checking the herd three times daily, especially during feeding and milking. Identify estrus cows promptly and breed them. For postpartum cows, aim for conception within 3–4 months after giving birth. Treat cows with reproductive issues promptly to reduce the number of open cows.
Fifth, focus on disease prevention and treatment. Strengthen feeding and management practices to boost the cows' immunity. Conduct regular disinfection and administer vaccines to prevent infectious diseases. Promptly treat common ailments such as mastitis and metritis to maintain milk quality and overall health. Regular monitoring and care are essential to ensure a healthy and productive herd.
