First, the clever straw processing. Ammonialization of wheat straw and rice straw is "smartly" handled, soft grass is hardened, and hay becomes wetter. Method is: the wheat straw, straw, etc. into a short section of 2-3 cm, 100 kg of crushed grass plus 4 kg of urea. Dissolve the urea with 40 kg of water and stir it in the crushed wheat straw or straw. Stir the mixture well and put it into a concrete tank or a large cylinder. Compact, seal, and airproof. Generally, the ammoniation is performed in one month in winter. Ammonium forage, soft and aromatic, cows love to eat, easy to digest, increase fast. Each cow feeds 10-15 kilograms. Second, forage with clever. Feeding cattle in winter, because there is no grass, the forage should be diversified, with short grass with long grass, good grass with grass.

In addition, the color of forage grass is different, and its nutrient composition is also different. In general, green hay contains high nutrients, yellow hay is poor, and white hay is worse. It should be done in three colors. For example, green hay peanuts, sedge grass, corn leaves and white hay wheat straw and straw each account for 30%, yellow hay accounts for 40%, and three kinds of grass should be finely chopped and mixed to feed cows.

More than 6 months old calves feed 40-60 grams, 70-100 grams fattening cattle, adult cows feed 150 grams a day. Urea poor palatability, can be mixed with 1% and concentrate feed after mixing grass, do not drink water within half an hour after feeding. Fifth, the food quantity is arranged wisely. The winter months are long and short, not only feeding during the day, but also feeding a slot after 10 o'clock in the evening. On the grass, 13-15 kg. Six, drinking water Qiao Wen. Winter does not allow cattle to drink cold water, should drink warm water 15 °C -25 °C, but also add salt to the warm water, add 30 grams daily, into the temperature after the water soluble drinking, can reduce fire, reduce inflammation, increase appetite, Tim add. Seven, health and clever scraping brush. The excrement in the barn should be diligently laid out, and the soil should be kept dry to keep the house warm, clean, and dry.
