title: The application of new ideas on the protein requirements of the dairy cow.
abstract: The intake of undegradable dietary protein in a cow's early lactation may be a major factor in determining peak yield. The natural degradability of proteins varies with different feedstuffs. Maturity of crop, use of additives, drying or grinding all affect the degradability. Time spent in the rumen is an important factor in the amount of protein degraded.
