Extract

In commercial pig production, several diets are offered to pigs dependent on their age and/or weight. A common dietary regime includes at least four changes of diet from wean to finish but there is a lack of information in the literature regarding the optimum method of changing diet. A common practice is to abruptly change from one diet to the next, although an abrupt diet change has been reported to cause a disturbance in the gut flora resulting in diarrhoaea, especially in the post-weaning stage (Meyer et al 1974). The aim of the current study was to investigate the effect of changing diet in an abrupt, phased or free-choice manner on the performance of pigs from wean to finish.
