(1) The proportion of refined coarse material is reasonable, and the amount of refined feed is appropriately increased.
Tests have shown that when the ambient temperature is below 18°C, the cow needs to maintain 2.51 kJ per kilogram of metabolic mass for every 1°C drop, and needs to eat more energy feed to maintain milk production and body temperature. The usual practice is to increase the mix by 10% per day. In addition, in the winter, to control the proportion of water in the wet mix, it is best to feed dry or pelleted feed; if the full-mix diet is used, the moisture content should be controlled at 40% to 45%, not too wet to avoid freezing.
(2) Keep warm and keep warm, pay attention to livestock house hygiene
Prevent wind and thieves from attacking. The cattle bed should be covered with grass to avoid direct contact with the cold ground. Do not flush ground and cattle pen with water. Excreta discharged from steak and contaminated bedding should be treated in time.
(3) Ensure the quality of feed and provide sufficient drinking water. It is best to drink warm water for cows.
Experiments have shown that drinking more warm water can increase the milk production of dairy cows. There are fewer green and blue fodder in winter, so it is necessary to relatively increase the content of nutrients such as vitamins and minerals in feed. At the same time, we must do a good job of forage processing and fine materials. The feed must be clean and fresh. The frozen juicy feed and silage should be thawed before feeding. Mildew, rot, deterioration, trampled feed cannot be fed.
(4) Maintain the health of the car body and strengthen daily exercise and other daily management
Always brush the body of the cow to keep the body clean, improve the breathing of the skin and lungs, and improve blood circulation. Brushing the cow body often can increase the milk production by 8% to 10%.
