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 …

For the past several decades, nutrient requirement systems for beef cattle in North America
have recommended that dietary ME can be calculated as dietary DE× 0.82, but considerable …

A deterministic and mechanistic growth model was developed to dynamically predict growth
rate, accumulated weight, days required to reach target body composition, carcass weight …

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

Development of nutritional energetics can be traced to the 1400s. Lavoisier established
relationships among O2 use, CO2 production and heat production in the late 1700s, and the …

Livestock production efficiency is essential to improve the world food chain in terms of
making meat available to more people and reducing producer costs, while supporting …

Despite tremendous advancements in the livestock sector, additional opportunities exist to
improve even further livestock production around the globe. Forecasting is not an exact …

Models are representations of reality. The fields of nutrition, metabolism and biomedicine
have used models to aid in research and its applications since before World War II. A model …

Demands of domestic and foreign market specifications of carcass weight and fat cover, of
beef cattle, have led to the development of cattle growth models that predict fat cover to …

Until now, the development of precision livestock farming has been largely based on data
acquisition automation. The future challenge is to develop interpretative tools to capitalize …
