Extract

In the past selection programmes for pigs have been based on measurements from individually housed animals. The manual weighing of food and refusals to obtain information on individual food intake is labour-consuming, and the housing method different to that found on most commercial farms where growing pigs are housed in groups. The selection of pigs in one environment to be kept in another often leads to a discrepancy between performance results achieved by pig breeders and those obtained in a commercial situation (Merks, 1989).
