In early spring, the temperature is relatively cold, and the fodder is not very abundant during this season. The beef cattle must be properly managed in the following aspects. General feeding management measures. Mainly do a good job warming, deworming and stomach. Strengthen warm work and prevent thieves and drafts. In particular, we should pay more attention to keeping warm during the cold spell. Trichlorfon is taken internally and taken at a dose of 0.05 grams per kilogram once daily for 2 days. With 75 grams of Cyperus rotundus, 50 grams of dried tangerine peel, 75 grams of radish seeds, 75 grams of oyster shell, 5 grams of medlar, 100 grams of hawthorn, 100 grams of Divine Comedy, 100 grams of malt, 50 grams of betel nut, 50 grams of green skin, 50 grams of osmanthus, and licorice 50 grams, decoction once a day, each cow 1 day, once every 2 days, can increase the appetite of cattle. Strengthen drinking water and exercise regularly. Full house fattening. It is necessary to ensure adequate roughage to meet the activities of rumen microbes. Feeding 2~5kg of fine material on the day, at the same time, 25 grams of artificial salt, 25 grams of urea should be supplemented, and feeding time should be later than 8pm. 1. Ammoniad straw plus concentrate. Ammoniad straw can increase its nutritional value, improve palatability and digestibility. After ammoniated straw crude protein can be increased 1 to 2 times, organic matter digestibility can be increased by 20% to 30%, feed intake can be increased by 15% to 20%. 2. Silage plus fine material. In the agricultural area, the raw materials that can be used for silage are easily available. In particular, silage corn is a good feed for fattening beef cattle. Under the conditions of low concentrate content, feeding silage can achieve higher weight gain. The test confirmed that the corn stalks after ripening were stored in silage before they had become dry litter, and were still high-quality concentrates fed to beef cattle. Adding a certain amount of concentrate to fattening beef cattle could still achieve better weight gain. 3. Bad residue feed. The bad residue feed includes the by-products of winemaking, milling, and sugar production. Most of them are residues of watery substances left after the carbohydrates in the raw materials are extracted. These bad residue wastes have a high moisture content (70%). In addition to ~90%, the contents of crude fiber, crude protein, crude fat, etc. are all high, and the content of nitrogen-free extracts is low. The crude protein accounts for 20% to 40% of dry matter. Strict prevention.
