Numerous mathematical nutrition models have been developed in the last sixty years to
predict the dietary supply and requirement of farm animals' energy and protein. Although …

Farm planning has increased in complexity and importance as agriculture in the developed
world has become concentrated in larger, more specialized farm units. These changes have …

Systems approach techniques have been applied to modeling production systems for beef
cattle from the relatively micro‐level of tissues and organs to the macro‐level of farms and …

This paper outlines typical terminology for modeling and highlights key historical and
forthcoming aspects of mathematical modeling. Mathematical models (MM) are mental …

A mathematical computer model of beef cattle production systems was developed at
Montana State University. The objective of this report was to describe the rationale and …

A comparative mathematical and conceptual analysis of quantitative feed intake prediction
models for sheep was conducted. The objective was to extract underlying theoretical …

Two beef animal growth computer simulations were compared as to the effects of altering
feed energy density. Steers of varying initial degrees of fatness were evaluated. The BEEF …

Considerable progress has been made in the last 25 yr both in definition of components of
forage quality and in the development of animal and laboratory techniques for quality …

The quantitative description of either a plant or animal system is indeed complex. Describing
the plant/animal grazing interface presents an even greater challenge. The beef-forage …

A dynamic simulation model has been developed that relates beef animal performance to
environment, management practices and selective grazing of pastures. Daily measures of …
