New research shows a step-wise reduction in milk intake may facilitate rumen development. According to research in the July Journal of Dairy Science, rumen wall thickness, papillae length, papillae width and papillae concentration were all higher in step-fed calves than conventionally fed calves. Calves on the step-down method received milk at the rate of 20 percent of bodyweight, and later at 10 percent of bodyweight. Other calf-performance results were published earlier this year.
