Doing well in the feeding and management of dairy cows in winter has an important role in improving milk yield and quality.
Cold insulation of dairy cows is easily overlooked by people. People mistakenly believe that the low temperature has little effect on dairy cows, and “milk cows are afraid of heat and not afraid of cold†is relatively speaking. This sentence means that dairy cows (especially cows) have strong adaptability. As far as the black-and-white flocks that are farmed by farmers are concerned, the range of adaptation to the external environment temperature is 7°C~16°C. Below or above this range, the cow's own consumption will increase. Therefore, it is very important for the cows to keep warm during the cold season. At present, the measures taken by farmers to protect the cowshed are mainly windproof. At night, the windows are covered with curtains to prevent draughts. During the day, the sun comes out to open the windows to ventilate the air so that the humidity in the circle is too high.
At low temperatures, the amount of nutrients used to maintain and produce dairy cows in the winter increases accordingly. In the winter, high-level dairy cows can maintain good sensation and can effectively improve the cold resistance of dairy cows; if they are fed at low levels, they will have poor chills and winters will not be tolerant to cold. At the same time, due to the limited intake of cows, they cannot consume more dry matter. Therefore, it is necessary to add more nutrients in the forage. Farmers increased the proportion of oil residue in forage grass in winter, and the effect was good. In addition, it is forbidden to feed frozen feed during the winter. Keeping drinking warm water in the winter is an indispensable measure to prevent body heat consumption. In addition, the cows should be given proper exercise. One or two times a day, it is best to brush the cows, which can promote the blood circulation of the cows, strengthen the cows' resistance, and help maintain the health of the cows and increase the milk production.
