Quantitative prediction of feed intake in ruminants II. Conceptual and mathematical analysis of models for cattle Academic Article

abstract

• A comparative mathematical and conceptual analysis of quantitative feed intake prediction models for cattle was conducted. The objective was to analyse the theoretical basis of current cattle intake models and provide directions for experimental research. Results for the models analysed indicated (1) weak conceptual basis of models in the sense of ability to accommodate experimental data; (2) frequently problematic implementation in terms of mathematical properties of models; (3) absence of new hypotheses for experimental research provided by reviewed models. These findings agree with similar results obtained in an analysis of sheep models. Suggestions for improved model development, implementation and documentation are provided. 2001 Elsevier Science B.V. All rights reserved.
