Written by a globally-recognized authority, Systems Analysis of Livestock Production provides a comprehensive methodological overview of systems analysis (modelling/simulation/quantitative analysis) of livestock systems. It places the method of systems analysis into the epistemological context of livestock science. The book develops a rationale and a descriptive formalism for the use of systems analysis as a necessary element of livestock science. It provides the only methodological approach capable of considering, understanding and predicting the effects of genotype - environment interactions on the ecological and economic outcomes of livestock production.
