A South Korean study reported in the February Journal of Dairy Science shows that a step-wise reduction in the amount of milk fed to calves on a higher plane of nutrition yields a three-fold benefit.

During the study, calves fed whole milk at the rate of 20 percent of bodyweight, and later at 10 percent of bodyweight, gained more weight, were heavier and had better feed efficiency than conventionally fed calves.

For instance, the step-fed calves gained 111 percent more bodyweight between birth and 30 days of age and 41 percent more weight between 31 and 50 days of age than conventionally fed calves. The step-fed calves also were 32 pounds heavier at weaning at 50 days
of age.
