1. Adjust dietary ingredients to feed high-quality dairy cows with high-quality forages, and feed more concentrates or high-fat substances to increase the energy of the diet. Available beans, cottonseeds, and animal fats, supplemented by 1%~ 1.5% is appropriate. In the full-price diet, increase the protein level by 1% to 2% so that the protein content is within 19%, and the crude fiber content should not be excessive, especially for silage. Practice shows that dairy cows with a milk yield of more than 32 kilograms should be controlled at 17 to 22 kg/day in the fall for feeding silage. 2. Increase dairy cows' beverages to prepare milky cows with good palatability and nutrient-rich beverages. Promote dairy cows to increase appetite. Practice has shown that a ratio of 140 kilograms of feed to 600 kilograms of water per day is cooked into thin porridge-like beverages plus 9 kilograms of brown sugar. Pouring beverages to leftovers three times a day will make all the remaining ingredients eaten. 3. Do a good job in disease prevention and control. Do a good job in environmental sanitation, reduce disease in dairy cows, regularly disinfect cowsheds, deliver and abortion cows, and timely feed brown sugar wheat bran soup or amniotic fluid to promote the timely discharge of the tires. Do not milk at any time. Swab the breasts with warm water before milk and use 0.1% potassium permanganate after milking to reduce the incidence of mastitis.
