ARTICLE 64 FEED & ADDITIVE MAGAZINE August 2022 on P-release. The latter depends on the efficacy of the phytase in finding the last remaining phytate molecules as well as on the ability of the phytase to release P from partially degraded phytate, such as IP4 and IP3. The price of feed phosphates has increased dramatically during the last year (Graph 3). This has led nutritionists to look at the possibility of using phytase enzymes at higher concentrations (from 1,000 to 2,000 FTU/Kg) than they were normally using (500 to 1,000 FTU/kg) aiming to release more P. Beyond the mineral matrices usually applied (P, calcium and sodium), companies have also started to adopt strategies including additional matrix values in the formulate software, such as energy and amino acids. Prices of all raw materials and energy items (electricity, gas, fuel) have increased beyond record levels, due to the current economic and political situation. One of the strategies that AB Vista promotes is to use higher doses of phytase than normally are being used (above 1,000 FTU/Kg) for the purpose of releasing the maximum amount of nutrients from phytate molecules to eliminate its antinutritional effect in the diet. In addition, it is being Graph 2. Exercise in starter feed which shows the amount of MCP kilograms (Kg) per treated tonne that should be used in different diets depending on the dosage of phytate applied. Graph 3.
