Short communication: Comparison of the newly developed DVE/OEB (2010) system and the National Research Council (2001) model in modeling metabolic characteristics of proteins in dairy cattle.

Abstract

The truly absorbed protein in the small intestine/degraded protein balance (DVE/OEB)2010 system is a recently developed protein evaluation system for ruminants. The objective of this study was to compare the DVE/OEB2010 system with the National Research Council (2001) model in determining the metabolic characteristics of proteins in dairy cattle. The metabolic characteristics of proteins in bioethanol feedstock and their co-products were compared in terms of (1) truly absorbed rumen synthesized microbial protein in the small intestine; (2) truly absorbed rumen undegraded feed protein in the small intestine; (3) endogenous protein in the digestive tract; (4) total truly absorbed protein in the small intestine; and (5) protein degraded balance. The DVE/OEB2010 system predicted 30% more truly absorbed rumen synthesized microbial protein in the small intestine, 4% more truly absorbed rumen undegraded feed protein in the small intestine, 64% more endogenous protein, 9% more total truly absorbed protein in the small intestine, but 27% less degraded protein balance.
