1. Selecting and feeding hybrid cattle:
Hybrid cattle combine the excellent characters of different breeds and have obvious heterosis, which can produce a large number of high-quality beef in a short time. If there is no crossbred cattle, you can choose local castrated cattle of 3-8 years old, weighing 250 kg, medium fat, healthy and disease-free for short-term fattening.
2. Feeding ammoniated grass:
Feeding cattle with ammoniated grass can improve nutrient conversion rate, enhance palatability and reduce production cost. Ammoniated grass can be made by sealing in ammoniated room according to the ratio of 100 kg grass to 3 kg urea and 40 kg water. The ammoniated straw should be transferred to the open field on sunny days, and the stack should be turned over to release ammonia, and then piled indoors for later use after it has no ammonia smell. Feeding ammoniated grass requires a transition period of 7- 10 days, and the normal intake of cattle generally accounts for 2% of body weight. Feed it three times a day on the principle of eating well and not wasting. Grazing during the day in the grass season and mixing silage in winter and spring.
Thirdly, adding the mixture:
The reference formula of the mixture is: corn 60%, sesame cake or cotton cake 37%, flour 2%, salt 1%, and soybean meal can be used when there is no cake to reduce the feeding cost. Feed is fed regularly according to 1% of body weight and supplemented twice a day.
Fourth, add additives:
"Raising cattle scientifically and asking for meat from technology" is an important way to develop beef cattle industry and improve the efficiency of raising cattle. At present, the technology of planting weighting agent is widely used, which increases the yield of beef cattle and improves the feed reward. Fattening bulls at home can be planted at any time, and the effect of castration is the best, and the cows are not buried with medicine. For cattle with long feeding cycle, it can be repeatedly planted every 100 days/time, and the fattening effect is better.
V. Intensive management:
During the transition period of feeding ammoniated forage grass, albendazole 30 mg can be taken orally per kilogram of body weight, which can also strengthen the stomach and fatten the body. Grazing in the grass season is 1-2 months, and no less than 1 month is required in the later period. The fattening time of using high concentrate diet is 60-90 days. Gain weight until your back is full. Weighing 400kg, 300 yuan can make a profit. It is required that the material be wetted 1 hour before it can be mixed with grass evenly. Be sure to drink clean water twice a day when feeding. Cowshed should be dehumidified and padded frequently to keep it dry and clean.
