A production-mode genetic evaluation system for pigs using the multiple trait animal model has been developed to run on microcomputer systems. The system, called PIGBLUP, currently analyses four traits: average daily gain, backfat and feed conversion ratio in a production module and number of piglets born alive in a reproduction module. An interim updating module and a module to combine the estimated breeding values into a single index value based on economic, production and marketing data supplied by the individual breeder are also included. The general characteristics of the system, which is now being made available internationally, are described.
