Distiller's grains contain abundant nutrients, including 412 kcal/kg of total calories, 26% of crude protein in dry matter, 11.14% of crude fiber, 7.48% of crude fat, 12.17% of crude ash, and rich in ash. Vitamin A, yeast. The choice of fattening beef cattle The fattening beef cattle mainly choose shelf cattle, and they require healthy limbs with strong limbs, no digestive tract diseases, no infectious diseases, and compact fur. Generally, more than 200 kg of barns are important on the barn, preferably in Simmental, Angus, Limousin. The other varieties are the offspring of the father. Healthy male yak from 3 months to 4 months of age, after early training, can also adopt the way of fattening. Storage and access of vinasse Due to the heavy moisture content of distillers grains, it is not easy to keep them. Therefore, distillers grains from the distillery need to be properly kept. The best way is to build concrete pools for preservation or use thicker plastic bags for storage. When using the distiller's grains from the pond, the method of water level should be adopted, and it cannot be used on the facade to reduce the rot content of the distiller's grains. After each time it is taken from the pool and the plastic bag, the distiller's grains must be tightly covered with plastic film. Bags should be tightly packed to prevent distilleries from rot due to exposure to air. Pre-finishing technical measures 1. Deworming: After the beef cattle are on the bar, the beef cattle are dewormed with long-acting Avicel at a dosage of 1 ml per 50 kg body weight. After the first deworming, the drugs are repeated once in 10 days. 2. Jianwei: Chinese medicine preparations, such as cow stomach medicine, health ingots, etc., on the stomach for the cattle. If there is a slight diarrhea after the cow is on the fence, diarrhea should be followed by deworming and stomach. Complementary feed formula Due to the lower carbohydrate content and less mineral content in the distillers grains, it is necessary to supplement concentrates in the diet of beef cattle. 1.3 months to 4 months of age: 56% of corn, 22% of Maifupi, 16% of soybean meal, 4% of premix for cattle, 1% of calcium hydrogen phosphate, and 1% of salt. 2.4 months to -8 months of age: 52% of corn, Mafupi 32%, 12% of soybean meal, 4% of premix for cattle, 1% of calcium hydrogen phosphate, and 1% of salt. 3.8 months to 12 months of age: 54% of corn, 32% of momofee, 10% of soybean meal, 4% of bovine premix, 1% of calcium hydrogen phosphate, and 1% of salt. 4.12 months old or older: 46% of corn, Medvelope 32%, 15% of detoxified rapeseed cake, 3% of soybean meal, 4% of premix for cattle, 1% of calcium hydrogen phosphate, and 1% of salt. Distiller's grains and feed usage 1.3 months to -8 months of age: diet mix, every 50 kg of body weight, 3 kg of distiller's grains, 8 kg of green (crude) feed, and 0.5 kg of supplemented concentrate. 2.8 months of age to slaughter: the amount of distiller's grains, every 50 kg of body weight, 8 kg of distiller's grains, 5 kg of green (crude) feed, and 0.5 kg of concentrated feed. Feeding and Management Technology 1. At the beginning of feeding distiller's grains, a few cows did not adapt, and it was necessary to adopt a method of step-by-step training, from less to more until the cows were fully adapted. The distiller's grain used every day is taken out of the pit and mixed with the concentrate. After feeding twice a day, the cow will consume the distiller's grain and concentrated feed and then feed it into the green (crude) feed. After one hour, the feed is sufficient. Clean drinking water. 2. The distiller's grains are mixed and freshly fed. You cannot mix feeds for several days at a time. Do not feed moldy distiller's grains. If you are buying fresh vinasse from a winery, you cannot feed them too much at a time to prevent bovine alcohol poisoning. . 3. Because of the heavier acidity of lees, and the daily feeding of a certain amount of concentrate, over time, it is easy to cause hyperacidity and auto acidosis. Therefore, it is necessary to feed sodium bicarbonate every day. The specific method is based on each cow. The amount of 5 grams per day is mixed with distiller's grains and concentrate feed and evenly fed. 4. Before feeding each feed, carefully check whether there is residual feed in the feed tank. If there is, you must clean up the remaining feed to feed the new feed to avoid the gastrointestinal diseases caused by the corrupt feed. 5. When formulating concentrate feed, be careful not to use moldy feed ingredients to prevent aflatoxin poisoning. 6. When feeding the feed, pay attention to remove the impurities in the feed, such as plastic wire, stone, iron wire, plastic bag residue, etc., so as not to stab cattle stomach and affect the ruminant of cattle. 7. Regular quantification. Feeding feeds on a daily basis is basically the same, and cannot be separated by more than one hour from the previous day, so as not to disturb the conditioned reflexes of cattle feeding. 8. Regularly brush the skin of cattle to increase blood circulation and reduce the incidence of skin diseases. 9. Regularly clean up the excreta of the cows, wash the cowshed as little as possible in the winter, and give the cow a clean, dry environment. Keep warm and cold in winter, and keep cool in summer. Epidemic prevention measures 1. Regular vaccination to prevent the occurrence of infectious diseases. In the spring and autumn season, according to the immunization program, the prevention of vaccination against foot-and-mouth disease, cattle pasteurellosis, and bovine emphysema is required. 2. Strictly implement the introduction regulations of the relevant departments, do not arbitrarily introduce from outside, do not introduce from the epidemic area, do local observations for isolation observation, and wait for the quarantine to expire. 3. Regularly work on cattle deworming to avoid parasite infection. 4. Do a good job of regular disinfection of cattle farms and barns to kill the disease. 5. When the herd develops an epidemic situation, the animal epidemic prevention department shall be notified immediately and measures taken to eliminate the epidemic. 6. No dead cows can be dissected in cattle farms and cattle houses. Diseased dead cows are to be buried or burned innocently. No dead carcasses can be thrown randomly.
