1. Choose to feed hybrid cattle. The hybrid cattle concentrates the good traits of different varieties, has obvious hybridization advantages, and can produce a large amount of high-quality beef in a short time. If there is no hybrid cattle, local calves aged 3 to 8 years old, weighing 250 kg, moderately sensational, and disease-free can be selected for short-term fattening.
2. Feed ammoniated grass. Feeding cows with ammoniated grass can increase nutrient conversion, enhance palatability, and reduce production costs. According to the ratio of 100 kg of grass, 3 kg of urea and 40 kg of water, the ammoniated chamber was sealed to produce ammoniated grass. The ammoniated straw should be transferred to the open space during sunny days and be continuously turned to release ammonia. After the ammonia taste is exhausted, it will be stored in the room for use. Aminated grass feeding should have a transition period of 7 to 10 days. The normal feeding amount for beef cattle usually accounts for 2% of the body weight. The principles of eating and drinking are not waste, and they are fed 3 times a day.
3. Make up the mix. The reference formula for the mixture was 60% corn, 37% cake, 2% starch, and 1% salt. According to the weight of 1% of the cow's body weight, the mixture was fed twice a day.
4. Add additives. "Cultivating cattle by science and technology to meat" is an important way to develop the beef industry and increase the efficiency of beef cattle. At present, the application of a wide range of weight gain agent technology. Feeding fattening bulls can be planted at any time, and the weight gain of the calves is best. The fattened cows do not need to be buried. For cattle with a longer feeding period, they can be replanted at intervals of 100 days and the fattening effect is better.
5. Fine feed management. During the transitional period of feeding aminated forage, 30 mg of albendazole was administered per kilogram of body weight and the stomach should be taken after serving. During the fattening stage, the grass season is grazing for 1 to 2 months, and the rear stage requires no less than 1 month of house-feeding and fattening. The use of high-concentrate diets can be used for 60 to 90 days. When mixing materials, it is required to mix wet materials first, and then mix well with forage grass after one hour. In addition, clean water must be supplied twice a day and the wet bedding is often removed to keep the bullpen dry and clean.
