According to tests conducted by professional departments, the growth and development pattern of beef cattle is: The growth of beef cattle before 1 year of age is faster, and the growth rate is slower after 1 year old, especially after 2 years old. Taking the Charolais beef cattle as an example, the daily gain is 1.5 to 1.8 kg from birth to 6 months of age, and 0.9 to 1.05 kg from 7 to 12 months of age. The trial also showed that younger beef cattle need a lot less feed than older beef cattle to gain 1 kilogram. Therefore, from the perspective of total feed consumption, capital and equipment utilization, it is more advantageous to keep young cattle than to feed older cattle.
Therefore, the calves were weaned 4 to 6 months of age. In summer and autumn, grazing is the main method, and feed is properly added. Winter and spring are kept in plastic greenhouses. It is generally 1.5 years after the yak is born in the late fall and winter of the second year of the year. When the weight reaches 300 kg, it is the best slaughter period for beef cattle.
