Shelf cattle are cattle that have not been fattened or not enough to slaughter their body condition, such as the use of culled meat, milk cows, and old disabled cattle. Shepherd cows are usually purchased from the pastoral areas to the finishing farms in the agricultural areas, and used high-energy feed for short-term fattening to further increase fat deposition and improve meat quality. Distiller's grains fattening method This method is suitable for areas where there are rich and convenient sources of distiller's grains in the suburbs of Dazhong. Distillers' grains, fresh or dry beer vats can be used. 1 adult cattle fattening period is generally 80 to 90 days, young cattle 120 days. A large amount of hay and roughage was fed at the beginning, and only a small amount of vinasse was given to make it adaptable. After about 15 to 20 days, the amount of distiller's grains was increased and the amount of hay fed was reduced. To 35-40 kg, young cattle up to 20-25 kg. At the same time, it must be matched with a small amount of fine material and strong palatability (dry grass) to ensure its strong appetite. Feed twice a day, drink three times, and train in the middle and late fattening to control their activities. At the same time to regularly feed salt, usually 7 to 10 days. Liquor tank 15 to 20 kg, cornmeal 2.5 kg, 1 dry bean cake, 50 grams of bone meal, 50 grams of salt, 2.5 kg of corn stover (or straw). At noon to forage grass-based, add a small amount of fine material, sooner or later the main channel, fine material, the average daily gain of up to 1.3 to 1.65 kilograms. Straw and ammoniated straws have a large amount of crop stalks in the agricultural area. They are cheap beef cattle feeds. After the straws are treated with peramination, fermentation, and salinization, the nutritional value is improved, and the palatability and digestibility are improved. The beef cattle can freely eat ammoniated straw and feed energy feeds or cheap cottonseed cakes to obtain a higher fattening effect. The diet composition of fattening cattle is generally: 14 kg of ammoniated corn stover powder, 2 kg of compounding material, 33 g of additives, 33 g of salt, and the average daily weight gain can be more than 1 kg. Tofu dregs, powder residue, beet residue fattening method powder residue, bean curd residue, beet residue is a good feed for fattening cattle. Reasonable use can save fine material and reduce the cost of raising cattle. 1 bean curd fattening. The bean curd residue is generally freshly used. The amount of 400 grams of bovine cattle per day does not exceed 30 kg. Raw soybean curd residue is best cooked and then fed. The proportion of its diet is: 5 kg of fresh bean curd residue, 0.5 kg of corn flour, 30 g of salt, and 5 kg of crude material such as cereal grass. Daily gains up to 1 kg. 2 powder slag fattening. The maximum amount of fresh powdered slag is 30 kg per day. The diet consists of 9.5 kg of fresh starch residue, 2 kg of fresh beer pellets, 0.6 to 1 kg of dry chicken manure and 9.4 kg of silage corn. Grazing grass replenishing fattening method This method makes full use of the grass season, play a role in urea, short-term rapid fattening, there are significant economic benefits. The beef cattle with a weight of 250 kg were selected to take wild grazing during the day and three times early, middle and late nights. The mixed diet formula is: cornmeal 1.5kg, artificial salt 50g, urea 50g. Grass free to eat, eat enough. High-energy dietary fattening method This method is suitable for areas with sufficient concentrates. The weight of 300 kg of shelf cattle fattening program: 1 early (transition period), 15 to 20 days, the amount of concentrate material to give 1.5 to 2 kg, crude material is 40:60. 2 Medium-term (40-50 days), the amount of concentrated material is 3 to 4 kg, and the ratio of refined coarse material is 60 to 70:30 to 40. 3 In the later period (30-40 days), the amount of concentrated material is more than 4 kilograms per day, and the rough ratio is 70-80:20-30. The formula for mixing concentrates is: 75% to 80% of corn, 5% to 10% of wheat bran, 10% to 20% of soybean cake, 1% to 2% of salt, and 1% of additives.
