What are the specific requirements for supplementary feeding in grazing-based beef cattle fattening?

The first key point is to improve the pasture, enhancing its quality and grass yield, which means raising the nutritional level for the beef cattle; otherwise, the expected fattening results cannot be achieved, and there will be no good economic returns. Second, supplementary feeding is effective after the day's grazing is finished; do not give the beef cattle concentrated feed at the start of grazing. The supplementary concentrated feed should be crushed (such as corn). Third, during grazing, pay attention to providing sufficient drinking water and supplementing salt, with 30 to 50 grams per adult head of cattle per day. Fourth, to make up for the lack of minerals and trace elements in grazing beef cattle, pay attention to supplementing mineral and trace element additives.
