¿Fitasa más allá de los requerimientos?

La destrucción del fitato y la posible producción de inositol pueden ser los posibles beneficios
Cuando apareció por primera vez la fitasa en el mercado, hubo escepticismo sobre si había un beneficio financiero, así como una serie de otros problemas. Sin embargo, en las últimas dos décadas hemos visto que han desaparecido muchas de esas preocupaciones y que hoy en día se incluye fitasa en casi todas las dietas avícolas. Es fascinante ver que se expande el uso de la fitasa más allá de sólo la liberación del fósforo para reducir el costo de la dieta. ¿Cuáles son los verdaderos beneficios?

Preventing phytase matrix problems in poultry nutrition

Phytase matrices are derived through the amalgamation of bone ash, growth and balance/digestibility studies using methods that can result in inappropriate safety margins that expose the user to potential risks in the field.
Phytases entered commercial use in the early 1990s and are now widely included in monogastric diets. However, phosphorus (P) replacement values determined by controlled trials are not always replicated in the field, and feed manufacturers have become wary of recommendations, often reducing the P matrix value applied to the phytase.

Potential extraordinary turkey performance through high phytase feed dosages

Increasing phytase dosage could lead to improved turkey performance.
Phytases have traditionally been employed to reduce inorganic phosphate usage in monogastric rations, saving money and reducing phosphorus (P) pollution. However, two recent turkey trials show improved performance in response to higher phytase inclusions when phosphorus is not limiting, indicating this is linked more to phytate hydrolysis than phosphorus provision and suggesting commercial benefits from higher phytase doses.
