Influence of Natuphos® phytase and organic acids on the performance of growing/finishing pigs

Numerous studies have clearly shown that the digestibility of phosphorus in pig diets can be improved 20-30% by supplementation with Natuphos® phytase allowing the phosphate content of the feed to be reduced without the P-intake becoming deficient. It is also well accepted that organic acids can significantly improve performance of pigs, particularly up to 30kg liveweight, and recently that synergistic benefits result when both Natuphos® phytase and organic acids are included in the same ration. The objective of this study was to investigate the influence combining Natuphos® phytase (replacing calcium and phosphorus) and organic acids (liquid v dry product) on growing/finishing pig performance.
