Do beef calves use only milk from their dams for their diets?

When calves are first born, milk from their dam will be the major part of their diet. However, it is surprising, especially for calves that are born in the spring, our data indicates that they will start eating grass when they are 60 to 70 days of age. They will eat about 1.1 to 1.2 percent of their body weight on a dry matter basis of good quality grass starting at that age.
