Feeding Management Techniques for Winter Cows

Cows have a certain level of resistance to both cold and heat, but they still have temperature limits. The ideal temperature for dairy cows is between 12°C and 14°C, while pregnant and lactating cows prefer a slightly warmer range of 16°C to 20°C. Lactating dairy cows are more sensitive to temperature changes. When the temperature exceeds 24°C or drops below -4°C, milk production tends to decrease. Calves, on the other hand, require a much warmer environment, with an optimal temperature range of 35°C to 38°C. Proper management of cowshed density is essential once all the cows are housed. Good ventilation must be maintained to avoid high humidity, which can negatively impact cow health and milk yield. The relative humidity should not exceed 55%. Excessive moisture can cause discomfort, reduce productivity, and even lead to fungal infections in severe cases. Water temperature plays a crucial role in maintaining milk production. For lactating cows, drinking water that is too cold (below 8°C) can lower milk output because the body uses energy to warm the water. In winter, it's recommended to provide water at 9°C to 15°C. Studies show that cows drinking water at 0°C to 2°C can increase their milk production by 8.7%, producing about 0.57 liters more per day. Hot porridge around 38°C can also help improve cold resistance and boost milk yield by up to 10% in winter. Additionally, feeding cows with bran water at a temperature slightly higher than body temperature (1°C to 2°C) helps replenish fluids and provides warmth after calving. For calves, the drinking water temperature should be higher than for adult cattle, ideally between 35°C and 38°C. When bottle-feeding, milk should be heated and sterilized before being cooled to 35°C to 37°C. Extreme temperatures, either too hot or too cold, can harm the calf’s health. During winter, feed diversity is important. Adjust the feed ratio accordingly, increasing energy-rich feeds like corn by 20% to 50% while keeping protein sources stable. Silage, micro-feed, or brewer’s grains are better choices for roughage than green, juicy feed common in summer. A well-managed dairy herd follows a seasonal breeding pattern—“summer with spring, winter with autumn.” Breeding during winter helps avoid calving in hot weather, which is beneficial for both the cow and calf. Farmers should take advantage of this period to improve breeding success and ensure healthy calf development. Brushing the cow’s body regularly not only keeps it clean but also improves blood circulation, supports metabolism, and helps regulate body temperature. It also strengthens the immune system. It is recommended to brush cows twice daily, in the morning and evening, for 3 to 6 minutes each time, making sure to cover all areas thoroughly.

Bullet Solar Camera

Installing Bullet Solar Camera
1. Understand how solar monitoring works
The solar Security Camera mainly relies on its attached solar panel to convert the solar light into electricity and charge the built-in battery for monitoring. The integrated inverter in the monitoring can also convert the DC power from the solar panel to AC power, so as to provide power when the sun comes out. It is stored in its rechargeable battery during the day, and its power can maintain the continuous work of solar monitoring at night.
2. What are the advantages of solar monitoring over ordinary monitoring
Unlike wired common monitoring, it does not need to run wires to connect it to the power supply. They connect to the home safety system via a Wi Fi connection rather than a data cable. As a result, they are true wireless security solutions that are easier to install. With wired cameras, you need to place them on the wall where the power cord runs, or close to the wall outlet. In contrast, you can install additional solar monitoring anywhere, even if there is no outlet nearby.
3. Which functions are necessary in solar monitoring
Camera resolution, field of view, solar panel wattage, night vision, motion activation, remote monitoring and smartphone alarm. The resolution of the camera determines the sharpness of the monitored safety picture. Look for models with High Definition (HD) cameras or better. The field of view describes the coverage of the camera. Security monitoring with a wider view is always better. Night vision and motion activation indicate whether the camera can see at night and start recording when it detects motion in the coverage area. The wattage of the solar panel paired with the security camera indicates how much power it can generate from sunlight. The battery panel with higher wattage can charge the attached battery faster and provide more power for monitoring. Smartphone alerts and remote monitoring are designed to help you monitor your home or office in the absence.
4. Whether the sun monitoring can continue to work in cloudy days
The answer is yes. The solar panels connected to the solar monitoring system generate less power in cloudy and rainy days, but the excess power stored in rechargeable batteries in sunny days can help them survive rainy and cloudy days.
