The shelf for short-term intensive fattening mainly grows muscles in the early period of cattle, and there is not much fat deposition. As long as a large amount of nutrient-rich roughage and an appropriate amount of concentrated feed containing more protein are provided, and sufficient water is provided, the cow will become a ","forming". At this time, the weight gain ratio of cattle is very low, but if slaughter is not worthwhile, because it has a low meat yield, poor meat quality, and can't sell a good price, this is what people usually call “water maggot†or “virtualâ€è†˜". The late fattening period refers to the month before the slaughter of beef cattle. This stage is a crucial period for improving the quality of beef, ensuring beef safety, increasing carcass weight and net meat rate. It is very important to strengthen the feeding and management at this stage. We should pay attention to the following points: 1 Increase the energy level of the diet. The finishing formula of beef cattle at the late stage of fattening should be set separately to highlight the energy substances. If the conditions permit, appropriate amount of animal and vegetable fats and oils can be added to the diet, which can account for 1% to 3% of the amount of refined feed, and appropriate reduction of protein raw materials. Dosage, pay attention to meet the supply of minerals, vitamins and other nutrients. 2 The ratio of supply of forage and concentrate feed is not more than 4:6, which is calculated after being dried. 3 control the amount of concentrate feed. A fattening cow with a weight of about 500 kilograms will supply no less than 6 kilograms of mixed concentrate on a daily basis. If calculated on the basis of the total amount of diet, the highest amount of concentrated feed can account for 85% of the dry matter in the diet. The forages provided by the 4 need high energy, easy digestion, good palatability, and high biological utilization value. 5 Create a quiet breeding environment, less bombardment, less scaring, and ensure that the cattle bed and playground are soft and sanitary. 6 Observe the feeding and defecation of cattle, and deal with the abnormal problems in the feeding process in time. 7 Prohibit the use of antibiotics and drugs and additives that do not meet safety requirements. The body condition of fattening cattle can reach the following standard at the right time: (1) There are fewer skin folds, full body lumps, and no exposed star skeleton. 2 Feed intake decreased, abdominal circumference shrank, and he did not want to move around. 3 When the hips are full, there are no visible protrusions on either side of the tail. 4 The front of the chest is prominent and round. 5 The skin of the crotch is tightly gripped by the hand, and the hand feels a thick feeling on the lower back. In addition, it is necessary to pay attention to selling fattening cattle to slaughtered enterprises with strict grading and high credit, because such enterprises can implement superior prices and superior prices to ensure the interests of farmers.
