Short-term strength fattening of beef cattle is to fertilize the rack cattle with high-energy diets. The beef cattle that are used for the strength of fattening are usually shelf cattle of 2.3 years old and weighing about 300 kilograms. This bovine skeleton has basically grown. Therefore, the purpose of short-term strength fattening is to improve the quality of beef and increase the degree of skewness of the cattle in order to meet the needs of exporting cattle; in addition, short-term strength fattening of shelf cattle can reduce the consumption of “maintaining needsâ€. Reduce total energy consumption. Therefore, the development of short-term fattening of cattle can not only improve the quality of commercial cattle, but also reduce the cost of raising and speed up cash flow. In recent years, we have promoted the short-term fattening method of beef cattle in field trials of some cattle raising specialties and achieved remarkable results. Tests show that the short-term intensity of fattening beef cattle can reach a maximum daily gain of 1.35 kilograms, a weight gain of 0.90 kilograms over that of normal fattening methods. When the weights reach 340 kilograms, the fattening method is generally used to maintain the required energy ratio over short-term strength. The fattening method is 2 times more, and the total energy needs about 90% more. The 150-day strength fattening method is now carried out on a shelf weight of 300 kilograms of cattle. The proportion of concentrates in the diet is 55% (45% for forage-based roughage) during the first 20 days of birth, and crude protein levels in the diet. About 12%; daily intake of dry matter quality (finger, total amount of roughage) is about 7.6 kilograms per head. From 21 to 60 days, the proportion of concentrate in the diet is 75% (25% of the forage based on forage grass), the crude protein level of the diet is 10%, and the daily dry matter intake per head (finger, roughage Total amount) is 8.5 kg. 61 to 150 days, the proportion of concentrates in the diet is 80% to 85% (20% to 15% for forage-based coarse material); the crude protein level in the diet is 10%; each head feeds daily The dry matter quality (referring to the total amount of refined and roughage) was 10.2 kg.
The following matters should be noted when developing beef cattle fattening:
1 The shelf cows newly purchased from foreign countries are fed for a recovery period of 10 to 15 days in order to restore the fatigue caused by long-distance transportation or rushing out and adapt to new feed points in terms of feed, feeding methods, drinking water and the environment. . During the recovery period, the feed was mainly dry and coarse (corn stalk, dry grass) or 50% dry coarse material plus 50% silage. After feeding during the recovery period, they are fed for a transition period of 15 to 20 days. That is, the feed transitions from coarse material type to fine material type. The specific method is: the fine material and roughage plus adequate amount of water and mix well, so that the fine material can be attached to the rough material; or the fine material and the silage material and then feed after feeding, so that after several consecutive feeding, fattening cattle You can get used to eating fine food. Gradually increase the proportion of concentrates in the ration. At the end of the transitional period, the proportion of concentrates should account for 40% to 45%.
2 Observe the ruminating activities of cattle and find out if they are abnormal. Pay special attention to bulging disease and laziness.
3 Ensure that drinking water is sufficient throughout the fattening period.
4 Provide a good environment. The cowshed should be cool in winter and cool in summer, light and airy, clean and hygienic, and keep quiet; Fertility period should be fixed and kept in order to minimize the movement; regular brushing of cattle body, keeping body surface clean and hygienic, and doing a good job in vivo and in vitro Insect control.
