High phytase doses can benefit both pigs and poultry, but only when used correctly in feed formulations, said academics at the 2nd International Phytase Summit, which took place in Rome, Italy, in December 2012.

Phytase is being used increasingly by the animal production industry to destroy the anti-nutrient phytate that is present in many plant-based foodstuffs. But as well as championing the use of phytase, particularly for improving nutrient digestion, summit delegates advised caution when formulating feeds with increasing phytase levels. Sessions at the summit covered mega-dosing and using nutritional geometry in feed formulation.
