How to feed beef cattle and the method of feeding beef cattle

1, and the suitable temperature for cattle growth is 10-25℃. Because the enclosed house is used in captivity, it is required that the fence has good lighting, drainage, ventilation and heat preservation performance, which is convenient for disinfection, ventilation, temperature and humidity adjustment in the house, fly driving and mouse killing. At the same time, it is required that there is no noise, water quality and air pollution around.

2. Choose healthy calves with weaning weight of about 200kg at the age of 5-6 months. Angus, Limousin, Charolais, Simmental and Piedmont are the best parents. Before entering the pen, the pen should be completely disinfected, and the newly purchased calves should also be disinfected with 0.3% peracetic acid solution, and the cows with more lice mites should be sprayed with 2% trichlorfon solution for expulsion.

3. The adaptation period is generally 15-20 days. During this period, adjust the diet of cattle, feed some digestible forage, and observe their food intake and activities. After 7 days, deworming was started, and the dosage was 0. 1g per head per kilogram of body weight. If there are ectoparasites, trichlorfon can be used again at a dose of 40 mg per kilogram of body weight on the seventh day after deworming. From the 5th day after warehousing, 30g of salt, 20-60g of urea, 40-60g of rumen element, and 2-7kg of distiller's grains mixture (5 parts of distiller's grains 1 part of chaff, in which distiller's grains, urea and rumen element are gradually added from small to large, and mixed with other diets during feeding to form wet feed, and after eating, 65438. If there is ammoniated feed, you can gradually replace coarse feed with ammoniated feed or micro-storage feed instead of urea. Strengthen epidemic prevention of cattle entering the pen and inject corresponding vaccines regularly.

4. The fattening period needs 65,438+065,438+0-65,438+03 months, with pre-fattening before weighing 250 kg and intensive fattening from 250 kg. At this stage, cattle can be given an injection of fertilizer, and the meat quality can meet the international export standards after use. 1 time. When entering the fattening period, it is necessary to limit the activities of cattle, keep them in a shed and feed them at 6 o'clock every morning and evening 1 time. Feed coarse feed first and then concentrate feed, and the water temperature shall not be lower than 4℃. According to the nutritional needs of cattle at different growth stages, the ration is reasonably distributed and the feed is changed gradually in 2-3 days. In the whole fattening process, we should pay attention to the feed intake and digestion of cattle, so as to find problems in time and solve them quickly, and try to avoid sudden death such as acidosis, urea (ammonia, poisoning, etc. ). If you have symptoms such as anxiety, nystagmus and foaming at the mouth within 1 hour after eating, you should immediately inject cardiotonic diuretics, and at the same time measure the pH value of rumen and urine with litmus test paper (the normal pH value of cow urine is 7.7-). When the urine pH value is higher than the normal value, give the cow 500 ml vinegar and 500- 1000 ml sugar water; If the urine is acidic, give them 200 g soda and 500 ml water, and give them infusion, gastric lavage and diarrhea.
