The rewards of using a modelling approach in directing poultry research

Abstract

1. The purpose of this paper was to demonstrate the advantages of using a good theory as the basis for designing and conducting research, using personal experience of developing a simulation model to predict food intake in laying hens and broiler breeders.

2. To develop such a model, research projects were designed to measure, among others, the effect of lighting programmes on age at sexual maturity, changes in internal cycle length, egg and body component weights over time, effects of temperature on performance, and to determine whether these birds would make use of body lipid reserves as an energy source.

3. Most of the experiments described here were conceived and conducted only because they were seen as a means of collecting information required for the development of empirical and mechanistic models, both of which have contributed to a better understanding of the birds themselves, as well as to the basis for predicting food intake in broiler breeders and laying hens.

4. For those researchers seeking ideas for further study, there is no better way of generating such ideas than by first developing a theory of the subject to be studied, the greatest benefit from this approach being that such targeted research is bound to be new, innovative and useful.
