The addition of a Buttiauxella sp. phytase to lactating sow diets deficient in phosphorus and calcium reduces weight loss and improves nutrient digestibility

This study shows that the addition of phytase to sow diets at 250 FTU/kg is able to replace 0.16% available P and 0.15% Ca in lactating sows diets, enabling producers to safely lower the level of Ca and P in sow diets. However, higher doses up to 2,000 FTU/kg will have further beneficial effects on BW loss, especially in older sows.
