The basis of the proposed scheme introduced by the A.R.C. (1980) for calculating the protein requirements of ruminants is the division of the protein requirement into two parts, (1) a minimum rumen degradable protein (RDP) supply to satisfy the requirements of the rumen microflora for cell wall synthesis, (2) a minimum undegradable protein (UDP) supply (protein that passes through the rumen to the intestine) which supplements the microbial protein produced in the rumen ensuring the tissue protein requirements of the ruminant can be met. The purpose of the experiment reported here was to investigate the effects on lactation parameters of feeding early lactation cattle levels of UDP or RDP above the minimum requirements proposed by the A.R.C. (1980).
