The aim of this paper is to derive economic weights for parameters of the Technisen Model Varkersvoeding (TMV) growth model, in particular for feed intake and to illustrate the effects of different levels in these parameters on performance traits and economic weights for parameters of the growth model. It is found that economic weights for parameters of the growth model depend on the level of feed intake in relation to the optimum feed intake, while conventional breeding objectives always put a negative economic weight on feed intake. Advances in performance recording procedures to obtain information necessary to implement growth models into breeding programs are required. Electronic feeders that are able to control the level of feed intake for individual pigs together with electronic
scales and video images allow recording of the information necessary to implement growth models in genetic
evaluation systems.
