In early spring, the temperature is relatively cold, and the fodder is not very abundant this season, so beef cattle management and management must be strengthened. First, keep warm. Strengthen warm work and prevent thieves and drafts. In particular, we should pay more attention to keeping warm during the cold spell. Second, deworming. Trichlorfon is taken internally and taken at a dose of 0.05 grams per kilogram once daily for 2 days. Third, stomach. 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 cornus, 100 grams of Divine Comedy, 100 grams of malt, 50 grams of betel nut, 50 grams of green skin, 50 grams of Chinese wolfberry, and 50 licorice Grams, decoction one serving, one dose per cow per day for 2 days, can increase the appetite of the cow. Fourth, strengthen drinking water and exercise regularly. Requirements of water quality without pollution, proper drinking warm water, ensure adequate drinking water. Appropriate exercise is beneficial to the metabolism of cattle, promote digestion, increase the ability of cattle to adapt to changes in the external environment, and prevent the decline of bovine constitution and the occurrence of limb and foot disease. In the early spring, the fodder was insufficient. Grazing should not be carried out and full house fattening should be carried out in the house. It is necessary to ensure adequate roughage to meet the activities of rumen microbes. Feed 2-3 kg of concentrate at the same time, it should be supplemented with artificial salt 25 grams, 25 grams of urea, feeding time after 8 pm. 1, ammoniated straw plus fine material. Ammoniad straw can increase its nutritional value, improve palatability and digestibility. After ammoniated straw crude protein can be increased 1-2 times, organic matter digestibility can be increased by 20% to 30%, feed intake can be increased by 15% -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. Contaminated slag feeds include by-products of brewing, milling, and sugar making. Most of them are residues of water that are left after the extraction of carbohydrates in the raw materials. These bad slag wastes have a high moisture content ( 70% to 90%), the content of crude fiber, crude protein, crude fat, etc. are all higher, while the content of nitrogen-free extract is low. The crude protein accounts for 20% to 40% of dry matter. In the category of protein feeds, although the crude fiber content is relatively high (mostly between 10% and 20%), the digestibility of the various substances is similar to that of the raw materials. Therefore, in terms of dry matter, the energy value is similar to that of bran. Sixth, strict prevention and quarantine. Formulate scientific immunization procedures; timely prevent diseases, treat diseases, and plan immunizations in a timely manner; regularly disinfect, maintain the cleanliness of the feeding environment, prevent the increase and spread of pathogenic microorganisms; often observe the status of cattle's mental status, appetite, feces and so on. Keep brushing on the body regularly to keep the body clean.
