ResumoThe effects of dietary protein and phosphorus level, and phytase and/or xylanase addition on performance, nutrient digestibility and energy metabolism in finisher pigs were determined. Protein reduction increased nutrient digestibility, pig performance and dietary net energy. Phosphorus reduction increased heat production, and tended to negatively affect all parameters. Phytase increased daily gain and dietary metabolizable energy. Xylanase improved digestibility of nutrients and energy, but had no effect on dietary net energy. Phytase and xylanase addition were not additive.
