Abstract

A comprehensive mechanistic model of the lactating cow has been described by Baldwin and coworkers (Baldwin, 1995). Over the past year, we have undertaken enhancements to that model in an attempt to address deficiencies. Such work has led to significantly better fits to a reference data set (Hanigan et al, J Dairy Sci, 2001). The work described herein represents a challenge of that model with independent data.
